CCTV News:Made in Germany is synonymous with high quality in the eyes of many people. However, the latest frigate "Baden Wü rttemberg" made by German military enterprises for the German navy failed in the sea trial and had to go back to the factory for improvement.

　　　　　　 "Baden Wü rttemberg" was manufactured by ThyssenKrupp Marine System Company of Germany, with a length of 150 meters and a displacement of 7,000 tons, and the cost was as high as 2 billion euros, about 15.7 billion yuan. This new frigate will replace the existing "Bremen" class frigate.

　　　　　　 In recent sea trials, this expensive frigate has gone wrong. The German navy said that this was because the central computer system of the frigate failed to meet the standard.

　　　　　　 In this regard, the spokesman of the manufacturing enterprise said that they are very skilled in dealing with this kind of problem and can solve the current problem quickly.

　　　　　　 However, the German media "Kiel News" exposed more problems. It is reported that the radar system, electronic system and fire-retardant coating of the fuel tank of Baden Wü rttemberg have problems.

　　　　　　 The electronic system should have been an advantage of the Baden-Wü rttemberg, enabling it to carry fewer crew members to perform its tasks. However, the test shows that too much electronic equipment leads to frequent failures of software systems, frequent failures of shipborne radar, and frigates with ineffective radar can easily become enemy targets.

　　　　　　 The Wall Street Journal quoted critics as saying that during the design process, the frigate was not equipped with sonar system and torpedo launcher, and even if it was repaired, it would be difficult to resist submarine attacks.

　　　　　　 "Baden-Wü rttemberg" class frigate is a large frigate built by Germany in the 21st century, also known as F125. Its full-load displacement is as high as 7,200 tons, which is close to China’s 052D destroyer. This frigate combines the most advanced technology in Germany and is known as the "king of frigates" among the global navies.

　　　　　　 This warship, known as the "king of frigates", is equipped with a 127mm Otto Breda gun, which can be equipped with volcanic guided shells, and can accurately strike targets 100km away. Although it is classified as a frigate, its naval gun is more powerful than the main destroyers in many countries.

First, wonderful views

1. Cognition of varieties is the core factor of making money.

2. In investment transactions, we are not so much trading our own ideas as human nature.

3. Choosing a stop loss doesn’t mean completely giving up trading on that variety, but waiting patiently for the next better trading opportunity. This is my secret.

4. Risk control is always the focus in the transaction process, and controlling capital risk is always on the road.

5. Any variety will have a ceiling of price and a cost line.

6. When stopping loss, we should not only look at the range of market fluctuation, but also pay attention to the market sentiment.

7. Adding positions after floating profits is a big taboo in futures investment.

8. Wealth is the realization of cognition, and futures investment is actually the money to earn personal cognition.

9. Traders must make friends with data, establish their own database, and focus on inventory through the database.

10. The withdrawal of funds is a process that investors will inevitably experience in their growth, and it is an inevitable price to pay.

11. Futures trading is the human nature of investors, so the result of futures trading is actually the embodiment of human nature.. Only by constantly training and improving themselves can investors become more and more mature.

12. Positions reflect investors’ greed and fear of the market. When you are greedy enough, you will often add a lot of positions, and many mistakes will occur during this period.

Second, the introduction of Pan Wang

"Datian Aaron", a contestant in the National Futures Firm Competition of Big Handnet, was born in 1982, and is now 39 years old, from Shanghai.

After graduating from college, I worked as a project manager in an IT company in Shanghai. After resigning in 2014, I started to invest full-time, and I started to do futures in 2017. Amateurs like playing football. Good at trading based on fundamentals, expert in futures investment.

Third, performance analysis

As of August 16, 2022,Pan Wang’s accumulated net profit in Xiaotian Aaron, an entry account of Dapan Handnet, was more than 20.51 million yuan, accumulated profit was more than 22.79 million yuan, Sharp ratio was 2.72, and accumulated yield was 62.17%.

Pan Wang’s current entry account is "Datian Aaron". Since April 21, 2022, within 80 days of trading, the cumulative yield is 84.97%, the cumulative net profit is 5.19 million yuan, and the maximum withdrawal is 38.26%.

The transaction analysis artifact of "Seven-tailed Fox" in the large-scale mobile network analyzes the entry account of Pan Wang as follows:

Pan Wang is almost a full-variety transaction.It belongs to the style type of partial intraday trading based on fundamentals.

Panwang trades more in apples, palm oil and other varieties, accounting for nearly 25% of the positions. On April 29, 2022, the highest position reached 94.81%, and the lowest position rate was 48.61% on May 9.

Panwang’s profits in iron ore, apples, palm oil and thread all exceed 1 million yuan.It is profitable in black varieties such as coking coal and hot coil.

Fourth, the interview record

01

IT paves the way and lays a good foundation for your career

I have been doing futures for about 4 to 5 years. Before that, I was doing stocks. I participated in the futures competition of the big hand net for about two years. My previous account was "Xiaotian Aaron", but now I have changed my account to "Datian Aaron".

Before professional investment, I worked in an IT company. At that time, my main job was to manage projects.

From a professional point of view, my previous work experience did not help me much in my later investment work, mainly because my attributes were completely different and had no relevance, but it was actually helpful in a deeper level.

When managing the project, I considered it more and comprehensively, which laid a foundation for the cultivation of trading personality characteristics such as logical thinking, endurance, execution, endurance and mentality required by my later investment work.It is helpful in this respect.

02

At the beginning of the investment, there was a stumbling block to retreat.

When I started my amateur investment, I was always doing stocks.

In 2017, I began to contact futures, among which there was a leader. With his guidance and help, I slowly began to learn to do futures and have a better understanding of how to make good investments. Therefore, compared with ordinary futures investors, I may have taken fewer detours, which is a very lucky thing.

I have always used subjective trading based on fundamentals in futures, and I have never been exposed to programming.

In the early days of full-time futures trading, the biggest difficulty I encountered was the relatively large withdrawal of account funds.

The fund management method of investing in stocks is different from that of futures. When investing in stocks, it is basically Man Cang. Now it seems that compared with futures, the fluctuation of stocks is actually relatively small.

When I started to do futures, I had no experience in fund management, and my position was always heavy, so I often encountered a relatively large withdrawal of funds. Especially in the first two or three years, the withdrawal of funds was relatively large, almost more than 50% every year.

During that time, I always lost, won, rose and fell, and my account was often a roller coaster, and I didn’t do well.

It was not until the last two years that I slowly controlled the retreat, broke through the bottleneck and embarked on the road of steady profit.

To solve this biggest difficulty at the beginning, I mainly adopted the following methods:

First, strengthen research and strive to make it thorough.When I first started to do futures, I was actually an out-and-out novice. I didn’t know anything about varieties, almost completely, so I paid a lot of tuition for the first two years.

But in the past two years, with the gradual deepening of research work, I have become more and more familiar with the fundamentals of the varieties I trade, so I have become more and more confident.

The second is to control your own trading frequency.

If you are in full bloom, butterflies will come; If you are well, it will be sunny.

It is because I am more and more familiar with it that I make fewer and fewer mistakes when placing orders.

Therefore,Doing research well is the basis of fundamental traders.

The third is to strengthen fund management. The amount of money I invested in a single variety has gradually shrunk.There was no concept of fund management at the beginning, and now my position in a single variety is basically not higher than 30%, usually about 10% to 20%.

These changes made me control the retreat.

03

Strong knowledge of successful trading control risk

I think: the core of trading is to thoroughly understand the fundamentals, because we are not programmed trading, and we rely on the degree of cognition of a certain variety when trading.

In the past, my commodity futures trading was mainly apple, and then it gradually developed into other varieties. In fact, the methods are the same, and all transactions are based on their own research and understanding of varieties, in other words, cognition.Good cognition is the core factor of making money.

I am a subjective investor who focuses on fundamental trading. At the beginning of investment, I had both experience and lessons in variety selection, opening and closing positions, stop loss and take profit.

When I started trading futures full-time in 2017, the variety that traded more was Apple. Mainly because in 2017, Apple suffered a serious "cold spring", which led to a sharp rise in prices in 2018.

It was based on this fundamental factor that I chose to trade Apple at that time and earned my first bucket of gold in investing in futures.

Investors are essentially trading their own cognition and personality, and they also need luck.

"Success is Xiao He, and failure is me". After making money on trading apples, on the one hand, I managed my position badly; On the other hand, due to my lack of trading experience, I soon returned most of my profits to the market.

At that time, I didn’t have any knowledge about where the price of Apple might go up. I naively thought that it could go up all the time, and then I encountered a big retreat.

Therefore, the first trading experience of Apple had both the joy of success and the frustration of failure, but in any case, it brought me valuable experience through that trading process.

Since then, when I choose a certain trading product, I usually base it on whether I understand it or not. Only in this way will I start investing. Whether it is apple or other varieties later, I will open the warehouse only after I have studied it clearly.

Although the research before the transaction was well prepared and considered to be very certain, I would choose to stop if the fact that it showed in the market at that time made me lose money or was different from what I expected.

Now, I am very disgusted with making the loss bigger, which is absolutely unacceptable to me. It is normal to admit mistakes.

Choosing a stop loss doesn’t mean giving up trading on that variety completely, but waiting patiently for the next better and more certain trading opportunity. This is my secret.

My trading system, in fact, is not much technical. You can keep the list of making money; For the list of losing money, the stop loss will be firm. For example, if the capital loses 10% or 15%, then we will unconditionally cut positions.

Risk control is always the key point in the transaction process, and controlling the risk of funds is always on the road.

04

Take profit and stop loss, carefully judge the market.

The profit-taking method I adopted in the transaction is mainly based on the following aspects:

One is based on the understanding and familiarity of varieties.

For a variety like apple, first of all, 5 yuan a catty is a very high price; Secondly, it has a fixed fee brought by the delivery rules. For example, when the market price of crude oil exceeds $120, the general duration will not be too long.

Unfortunately, in 2018, I didn’t understand this at all.

Any variety will have a ceiling of price up (or high price will curb consumption) and a cost line down, which are two very important trading factors.

The second is based on the understanding of the historical price of a variety.If the market price of a certain variety reaches or approaches a historical high and the price deviates seriously, then we should also choose to take profit;

The third is based on the judgment of fundamentals.If the fundamentals of the market change, we will also take profit.

Since we buy with reference to fundamental factors before trading, we must track the fundamental changes in the market every day. When there is a fundamental change in fundamentals, then we will also take profit and leave.

There are similarities and differences between fundamental trading and technical trading.As long as the conditions change, then the transaction must change.In technical trading, we often buy and sell according to the situation of big yin or big yang; If you use fundamental trading, this is probably the same reason.

When stopping losses, we should not only pay attention to our own stop loss points, but also pay attention to the market sentiment.In trading, sometimes you can obviously feel that the market sentiment is not quite right or not quite what you imagined. If this happens, you can stop the loss earlier.

Sometimes, if you think it is possible that the market has made a temporary mistake, then the stop loss range can be slightly enlarged. Of course, this should be judged according to your own experience and trading feeling, provided that you have a thorough study of the fundamentals before you can enlarge or narrow the stop loss range.

As a trader, it is necessary to accumulate knowledge of fundamentals and trading ability. Otherwise, it is just a waste of time to do it year after year, and I have not grown up.

05

A big taboo for floating profit and jiacang futures investment

When I first made futures, I had a bad habit, that is, I liked to add positions after floating profits. Because your risk awareness is not strong enough, if you often add positions after floating profits, then a small fluctuation will destroy the profits you have accumulated for a long time.

I think:Adding positions after floating profits is a big taboo for futures investment.

On the one hand, when you plan the number of open positions, you should try to abide by it and not change it.

Now I have achieved that I will not add positions after floating profits, which also avoids the differentiation of mentality caused by fluctuations.

Fundamentals sometimes do lag. For example, when the market price of a variety fluctuates greatly, we sometimes have no way to know what happened in the first place. At this point, I will make some changes according to the market, so there will inevitably be some intraday trading.

When I feel that the trend is not quite right, or when the disk gives me a bad feeling, I will do some transactions, sometimes this is a helpless move to deal with risks.

Therefore, taking profit and stopping loss does not mean that the price must fall on the set ceiling or floor. When there are some fluctuations beyond your cognition in the market, you should also be vigilant. This is an experience.

Some programmed investors, they think that floating profits and adding positions is a better method, which has something to do with their trading types. While they are making floating profits and adding positions, I believe that they will inevitably match the corresponding stop loss bars, and the transactions are all matched.

We can’t just see the beginning of their transaction and not the end of their transaction.Any kind of transaction, whether fundamental or procedural, has a head-to-tail match.

We can’t "blind the eyes with one leaf, but we can’t see Mount Tai", just look at the surface and ignore the inside; It still depends on the integrity, systematicness and consistency of a strategy.

06

The Soul of Fundamental Research of Data Analysis

I have some experience in fundamental research, which can be used as a reference for investors who do fundamental research in the market.

Over the past five years, I have spent a lot of energy on data statistics. For example, Apple, including Zhuo Chuang’s data, analysts’ daily opinions, etc., we will pay attention to and carefully study and check. We track the inventory and delivery speed every week.

For example, if we want to make black varieties, then we must know the data of steel joint, steel valley and steel search.

At the same time, I will set up my own database and do their own data over the years, so as to make some comparisons and predictions for myself.

As long as you do more data, you will have a deeper understanding of a variety and an industry, and this understanding is our future wealth.

Wealth is the realization of cognition, and futures investment is actually making money from personal cognition.Maybe programmed trading may be different, but I think fundamental traders mainly rely on making cognitive money.

The best way to improve personal cognition is to study hard. When one’s knowledge accumulates to a certain extent, one can naturally discover real logic. As long as an investor’s cognition is improved to a certain extent, the investment efficiency will be improved.

I suggest you:Traders must make friends with data, establish their own database, and focus on factors such as output and inventory.

Investors should not only pay attention to the yield, inventory and consumption of varieties, but also learn to make charts themselves. The key is to improve their ability to analyze and find contradictions.

Although the data we need is cold on the surface, there are some opportunities for undercurrent; Investors need to spend time to analyze data, love data, build emotions with data, and find opportunities in love.

The data of some varieties over the years often imply certain laws or contradictions, and we need to catch it out.

Pay attention to the fundamentals, in addition to the above methods, you can usually participate in some research.

When I first made futures, I participated in the investigation of apples, glass, soda ash and sugar.

In those two years, I ran a lot and did a lot of research. However, I gradually realized that the research actually didn’t work very well. Because in that process, on the one hand, you can’t see a lot of things; On the other hand, many enterprises or industrial farmers, if you ask them something, people will actually take some subjective views.

Therefore, I think it is more objective to pay attention to the effect of the database. As long as you learn to analyze data, you can know what’s going on in the world without going out. So from the last two years, I basically stopped participating in the research, mainly doing data analysis and thinking for myself.

07

Facing the information science, identifying and grasping contradictions

No matter the stock market or the futures market, it is an effective market. In other words, when you see some information, the disk may have explained the changes brought about by this information.

If you only deal with this information every day, it will have little effect on the transaction, but it will make you indecisive because of the interweaving of information in the news every day.

In the market, most of the news is noise. As a fundamental player, you must remember that you can only trade any variety after seeing the biggest contradiction in fundamentals.

A while ago, I decided to invest in rebar trading, mainly because the market supply exceeds demand, while the demand is really sluggish, and there is a huge contradiction between supply and demand.

When an investor grasps the biggest contradiction in the market, he can and needs to see a lot of information in the market, but he must have the ability to distinguish, and don’t let the daily information change affect his trading decision.

If there is an inflection point in the market price and the fundamentals have indeed changed, then it is important to test a fundamental trader.

Investors should have the ability to grasp the detailed changes in fundamentals in a noisy market environment, which is determined by the trading skills and needs to be accumulated.

Because investment is a thing that needs to be accumulated, and the accumulation is thin, and haste makes waste.

08

Trading strategy method has no definite method to look at the market

My position cycle is long and short, and there is no fixed pattern.

There are not many trends in the market. Many times, the market fluctuates in shocks, and the holding time of a variety matches investors’ cognition of the variety.

If there is a big contradiction in the market, such as the coke and coking coal market in 2021, and there is a serious mismatch between supply and demand, then the holding period can be appropriately longer.

If the market only deals with short-term changes and prices often rise and fall, then this kind of trading is less involved.

If the market deals with major changes in fundamentals, the holding time will be relatively long.

Therefore,The length of holding positions mainly depends on whether the changing factors of fundamentals are large enough.

My entry account "Datian Aaron" has a maximum historical retracement of 35.84%, and the trading is still biased towards intraday trading. In fact, this is also a bad habit of mine, because I can’t help doing some transactions every day because of some time-sharing changes. In fact, most of these transactions are losing money, so this habit is not good, but the fundamental trading is not always holding on, which is two different things.

The varieties I trade cover almost all markets, including stock indexes, among which apples and palm oil account for the largest percentage.

My preference for variety selection is actually a reflection of my understanding of fundamentals. It can also be seen from the account of "Datian Aaron" that started in May 2022 that I trade more apples and palm oil.

I think, since that time, the market contradiction of these two varieties has been more prominent. Apple has indeed suffered a reduction in production this year, which is a relatively certain opportunity, so there was a previous wave of gains.

As for palm oil, when Indonesia accelerated its export after June 2022, we knew that it had gone through a big bull market for two or three years, and the price rose from more than 4,000 to around 12,000, which was already a very big increase, with the help of the Russian-Ukrainian war. However, after Indonesia accelerated its export, the fundamental situation changed completely, and we saw this.

In fact, palm oil is a variety that has fallen a lot and is smooth recently. If it is smooth, it is easy to hold it, including cotton and copper. There are obvious fundamental changes and it goes smoothly, which will be more friendly for the transaction. Therefore, palm oil and apples are the varieties that I traded more recently.

Followed by the black plate, there are also many transactions, including threads, iron ore, coking coal and coke. From May to now, these varieties are mainly traded.

09

Raise awareness. Iron ore earns more than one million yuan.

In the investment of iron ore, my profit reached more than 1.5 million yuan.

The investment result is the realization of personal cognition, and the fundamental trader earns the money of knowing the world.

The market of black varieties, starting from the monetization of shed reform in 2015, accelerated to "carbon neutral peak carbon dioxide emissions", and experienced a magnificent bull market, with all varieties increasing greatly.

In 2021, after the national "three red lines", we think that the market logic foundation of the black plate began to change. But it doesn’t mean that as soon as the fundamental situation changes, we have to trade immediately, and it sometimes takes time to change from quantitative to qualitative.

The real decline of the black system also began this year. Last year, it may be related to the global political and economic situation, especially the easing after the epidemic.

Starting from 2022, the United States will lead to contraction, and international varieties such as iron ore will be affected. Iron ore is a relatively volatile variety, which is related to both the black plate and the global macroeconomic environment. So it is a variety that I have made more in black.

Judging from the situation of supply and demand, everyone has already seen the reduction of steel production. In addition, the global economy is affected by the tightening caused by the interest rate increase in the United States. These factors are more obvious in iron ore. In addition, screw thread and "double coke" have also been done. These varieties have achieved good returns this year.

10

Laughing deeply understands the withdrawal of red dates with losses

My experience of losing money is very rich. Last year, about 60% of the capital interest in Xiaotian’s account was withdrawn.

The withdrawal of funds is a process that we will inevitably experience in the process of growing up, and it is an inevitable price to pay.

When the retracement happened, it seemed that we lost money, but in fact it helped us expose our own problems in the transaction and brought us an opportunity to reflect, correct and improve.

We have gradually enriched our experience in dealing with retracement, first, in fund management, and second, in grasping the fundamentals. This is a progressive process, and I hope I can slowly control the retreat after that.

Every big loss is a good accumulation of experience and a personal transformation. Every big loss experience is unforgettable, and every big loss variety is painful.

After each loss, I have a deeper understanding of a variety. In 2021, my big loss was on red dates. At that time, the production of red dates was reduced, and the price was predicted to rise.

For a variety like apple, we already know its ceiling price, but for a new variety like jujube, to be honest, there was still a lack of understanding of the price ceiling at that time, and the consumption power was overestimated.

Loss is not a bad thing; At least, for that variety, we will be more confident in the future, and the immediate loss is the cost that will not be lost in the future.

When trading red dates, my own position basis and reasons for opening positions were based on my own judgment at that time. The main basis was that I learned the information of jujube production reduction at the first time, which benefited from the information blessing of many friends and investment partners around me.

I know that after the production of red dates was reduced, I entered the market as soon as possible, although there were also exits on the way. Regulatory factors or various kinds of information from the market, such as less production than expected, will have a certain impact on intraday trading, but they have been taken down all the way, and the bottom warehouse has basically been there.

We thought there would be a higher price in the future, so we didn’t leave the position, but later there was a big retreat, basically like this.

When I fell, I was also carrying it at first. Until the New Year, I found that I really couldn’t keep up with my consumption. At that time, I decided to come out, but I had already retreated a lot of profits, so I made a wave and retreated a wave.

The biggest lesson we have learned is:The price of any variety in the transaction has a ceiling. This ceiling is essentially the point where high prices curb consumption.

Varieties such as red dates and apples are expensive to a certain extent, and people’s acceptance is poor. After doing it once, you will get a valuable experience, and you will know later.

In fact, my mood is rather depressed because the withdrawal of net worth is very large, and my psychological pressure is relatively great. But after you are out, you will let go. Adjust yourself as soon as possible to meet the next transaction. There will always be progress.

If you are small-minded, you can’t bear the fluctuation. When we finish the last transaction, we should invest in the next transaction with a brand-new mentality. Only by earnestly learning from the last experience and lessons can we do better and better.

11

It is common to study the stock market futures market carefully.

If we want to succeed in the stock and futures markets, we must study them thoroughly.

Fundamental trading, whether in stocks or futures, must be thoroughly studied.

For stocks, it is necessary to be able to calculate the profit of an enterprise in the future. The expectation of profit depends not only on your judgment of this industry, but also on your understanding of the profitability of the enterprise itself.

When we plan to invest in stocks, we can calculate how much money it will earn in the next year and what kind of valuation the market will give it, then we can figure out what price it will rise in the future. Although this calculation is not necessarily very reliable, at least you can know what its future trend should be like.

I used to do a lot of cyclical stocks, which have a certain connection with commodities, which is also a favorable help for me to transform into commodities later.

The price of goods will be reflected in the profits of listed companies; Similarly, the judgments on commodities and futures are basically the same.

We can draw some preliminary conclusions about stocks through calculation. For example, coal companies and mining companies can basically calculate their profits through the prices and costs of commodities. If you can give a correct valuation, you can probably figure out what price their share price will reach.

The same is true of futures. When you understand the relationship between supply and demand, you can know the ups and downs.

twelve

Reduce retracement management positions and strengthen self-discipline

Many people have ups and downs in futures investment, which is also a problem I encountered two years ago. That is to say, you can’t control the retreat, you can earn a lot when you earn, and you lose a lot when you retreat.

Futures trading sometimes embodies human nature. In this process, investors can only become mature day by day if they constantly experience and improve themselves.

Positions reflect the degree of greed and fear of investors. When you are greedy enough, you will often add a lot of positions, and many mistakes will occur during this period.

We should avoid the ups and downs in income and strive to reduce the retracement.First, to strengthen position management, we must have strict discipline.For example, ask yourself that the allocation of funds for a single variety should not exceed 20% or even 10% of the invested funds. As long as you can control yourself, then you can basically control the retreat.

The second is to improve personal cognition.Studying the fundamentals clearly can improve the winning rate.

If an investor not only improves the control of his own greed and fear, but also strengthens the cognition of the attributes of the goods themselves, it will certainly be of great help to control the withdrawal of funds and avoid ups and downs.

Investors can’t guarantee that the fundamental research they have done is correct, and the chance of making mistakes is inevitable.

When we place an order through fundamental research, if the market runs in the direction of research, then we should hold this order because you are right.

If there is a loss after two or three consecutive orders, it indicates that there may be something wrong with our research or the timing is wrong.Fundamental trading does not mean stubborn trading.

If the market trend does not match the research results, then we will start to question whether our research is correct. Is there anything else you haven’t noticed?

Sometimes my position will be higher, but this may be because there are many kinds of transactions. In fact, my position of a single variety will not exceed 20% now.

13

Short palm, seize the opportunity and make a big profit

I didn’t have many successful transactions in the past. Whether I made apples or red dates last year, although I made money, I made a big retreat.

I think it is a successful case to make palm oil in 2022.

At that time, when I saw Indonesia’s major turning point from banning the export of palm oil to accelerating the export one month later, I began to short palm oil, but unfortunately I didn’t get it from the beginning to the end.

Although the decline of palm oil exceeded my personal expectation, I basically entered the market at the highest point in this variety. Although I came out early, I didn’t retreat, so I was quite satisfied.

I was able to do this transaction better because:

First of all, thanks to our continuous tracking of its fundamental data.I have made detailed data on all oils and fats.

Secondly, seize the right opportunity to enter.At the moment when the contradiction between supply and demand occurred, I captured the information in time and was able to open the warehouse decisively.

Finally, the trading system and plan were strictly implemented.Instead of being a "frightened bird" in the market development, we have become a "snail that climbs up step by step".

This should be a successful case.

14

Hard work pays off.

Many fundamental traders are persistent and dedicated.Apart from the hobby of sports, I spend most of my life doing research except eating and sleeping.

I do data every day, and I buy a lot of data myself, such as Zhuo Chuang and Gang Lian. The time spent doing research is much longer than the time spent doing business. Except for trading, they are basically doing research.

With the accumulation of time, your cognition will continue to improve; You will become more and more familiar with all aspects of the variety. In the long run, you will have a qualitative change. When there are some fundamental changes in the varieties you are familiar with, it will be relatively easy and faster to grasp.

When each variety has a very clear sense and cognition in your mind, you are very skilled in it, and once the market changes, you will know how to judge.

Since 2017, I have accumulated nearly five years. Looking back now, it was relatively ignorant and naive.

Since 2019, I really accumulated the data and began to gradually understand various varieties.

15

Looking forward to the future, my heart is still climbing hard.

Many subjective traders around me have a lot of ups and downs.

When losing money, the mentality will not be too good.If an investor has a large position, the pressure can be imagined when he encounters losses. This is also related to the investor’s personality.

No matter what kind of investment you make, don’t be too heavy, which is the core of futures trading. It is necessary to grasp the fundamental situation and control human nature.

The result of the transaction matches the investor’s personality.A successful investor, after trading for several years, should be able to realize: what kind of person am I? What is my risk tolerance? Will I be anxious? Everyone’s personality is different, and the answers cannot be the same.

Experience can be replicated.If we have a knowledge of our own personality, then we will slowly explore a set of position management methods suitable for us. Everyone’s personality experience is different, and naturally it will not be repeated when it comes to trading, so everyone should optimize their own model, and it is more difficult to completely change it.

I hope I can do better in futures.

Many commodities have fallen for a long time this year, so you can pay attention to it. Varieties that have not fallen sharply, such as crude oil and soybean meal, can still be concerned.

Whether it is a subjective transaction or a programmed transaction, as long as it can make money continuously and steadily, it is a good way to trade for yourself.

Many excellent programmed trading teams or individuals have small retracement, well-controlled capital curve, stable income and excellent performance. The key is to find their own methods.

Therefore, I also agree with programmatic trading, but I will still stick to my fundamental trading method.

I am full of curiosity about this world, and I have a heart that I always want to explore and know. When I study a variety and understand its silent language and movement trend, I will have a great sense of accomplishment.This feeling, if I engage in programmatic trading, may not be available.

The ruler is short and the inch is long, and what suits you is the best.In the commodity market, behind the price changes of different varieties, there are many contradictions in economy, politics, macro-policy, culture, company management and supply and demand. If I can know more about the world, understand it more deeply, and reflect it with good results in my trading account, this is my greatest sense of accomplishment and my greatest happiness.

For traders, courage is definitely a double-edged sword. I think it’s better to be timid.

There are many ups and downs in the market, and not many people can make money for a long time and steadily.

A wave of big market can achieve a group of people; But after two years, you will find that many people have disappeared again. This is the normal state of investment.

Instead of ups and downs like that, it is better to take small steps steadily every day and not be too greedy. I prefer this mode.

Message exchange and learning in the competition have been greatly improved

Two years ago, my trading account retreated a lot, so I always wanted to find a good solution, and I wanted to communicate with experts and learn more from you.

I’ve tried many ways before, but the results are not ideal.Later, I found that it might be a good idea to participate in the competition, because during the competition, I can see the fund curves and net worth charts of some other excellent players, and the master’s practice will be of great enlightenment and help to me; Compared with our own capital curve, we will find many problems, understand many truths, correct many shortcomings and improve our requirements.Therefore, with this purpose in mind, I signed up for the big hand net competition.

There is a "seven-tailed fox" transaction analysis software in Dapan. com, which can conduct a comprehensive dialysis of its own fund accounts, which is better than some curve analysis of fund management we have done ourselves. So I like and cherish such an opportunity to learn and improve.

I hope that the large-scale mobile phone network can continue to be run, and the better it is! I also hope that more and more investors can join this platform of learning, communication and improvement, and I hope that everyone can make money!

200609 was compiled from an exclusive interview with the contestant "Da Tian Aaron"

　　　[Disclaimer] This article only represents the views of the third party and does not represent the position of Hexun. Investors should operate accordingly, at their own risk.

　　Although my son just entered the first grade of primary school this year, Xu Ying has started asking around about the registration of children’s programming. "Ignorance of programming is illiteracy in the new era", and the voice from the training institution made her feel anxious. Knowing nothing about programming, she was worried that her son would lose at the starting line and decided to take action as soon as possible.

　　The tuition fee, which starts at ten thousand yuan a year, is not a small sum for her, but it may not be able to get reliable teaching quality. The reporter’s investigation found that some institutions have very low requirements for franchisees’ teachers, and zero-based staff can take up their posts and teach after one week of training, and some even take as short as two or three days.

　　student recruitment

　　Kindergarten children with tuition fees of tens of thousands are "the most sought after"

　　Searching for "children’s programming" on the Internet, a variety of organization names appeared in front of Xu Ying. "Online and offline, most of the course contents include Scratch, Python, and robot programming, like me ‘ Layman ’ I really don’t know how to choose. " Under the entanglement, Xu Ying intends to conduct a field trip to the offline institutions closer to home.

　　"I thought I acted early, but I didn’t expect it to be ‘ Half a beat ’ 。” In the training institution, Xu Ying was surprised to see many children who just went to kindergarten. According to the course consultant, in the past, children’s programming was based on computer operation, and the starting point was relatively high. Generally, they had to go to primary school at least to get started. Nowadays, the Legou building block course, which focuses on construction, has been incorporated into the whole system as "programming thinking enlightenment", and children aged 3 to 6 have become the training objects of institutions.

　　In the investigation, the reporter also found that the trend of younger children’s programming is becoming more and more obvious. Take Chaoyang Joy City as an example. Within 1km of Fiona Fang, there are at least eight institutions offering children’s programming courses, and seven of them are for preschool children.

　　"Early exposure to these can exercise children’s logical thinking ability, and later learning higher-level programming has an advantage over others." In the consultation, the course consultant strongly recommended to the reporter, "Now, there are construction competitions in the kindergarten stage. After going to primary school, programming learning is more helpful for further studies. For example, at the beginning of junior high school, if you can have a certificate to participate in the competition, you can give priority to admission. In the middle school stage, there is also the Informatics Olympics, and programming can increase the weight of children entering prestigious schools. "

　　According to the course consultant, the institution currently provides two learning paths. One is based on hardware, focusing on the intelligent control of robots by programming. The other is software-oriented. At the age of 6, you can learn Scratch graphic programming, and at the age of 9, you can enter Python code programming. After that, there are courses specifically for informatics Olympics.

　　"The tuition fees are different at different stages, and the enlightenment stage is cheaper." According to the course consultant, there are usually 80 class hours in a school year, and each class is divided into 2 classes. Lego creative enlightenment for 3 to 6 years old is at least 8,400 yuan, while Scratch’s discount is at least 15,000 yuan, which is equivalent to 375 yuan per class.

　　survey

　　Send courseware to teach speech teachers a week "out of the oven"

　　In the online search for children’s programming, in addition to a variety of marketing advertisements, there are many joining advertisements for national investment promotion. The reporter immediately called a Beijing-based institution on the grounds of consulting and joining, and the staff said that the one-time fee was 106,000. There are not too many rigid requirements for franchisees except that the venue is suggested to be 150 square meters to 200 square meters and equipped with 3 to 4 classrooms.

　　When the reporter raised the concern that the teachers were not professional enough, the staff said that the programming course was divided into different stages and the requirements for teachers were different. Among them, the 4-to 7-year-old programming thinking enlightenment does not need to be carried out on the computer, as long as the teaching AIDS developed by the organization are used; From 7 to 12 years old, the first half is Scratch graphical programming, and the second half is Python code programming. From 12 to 18 years old, it is more advanced artificial intelligence and C++ algorithm. "The requirements for teachers in the enlightenment and Scratch stages of programming thinking are lower, as long as it is a college diploma or above. There is no restriction on majors. The key is to have affinity. You can start these two stages of courses first. When you go to an advanced course, you need a background in computer and other related majors, and it is not too late to recruit the right person. " The staff said that the recruited teachers will have a week of offline training at the Beijing headquarters, and even if they are zero-based, they can start teaching soon.

　　"Generally speaking, a single store only needs two or three teachers. Under the age of seven, a teacher can take six or eight students. If it is over 7 years old, a teacher can bring 8 to 10 students. " Aware of the reporter’s hesitation, the staff further stated that programming has been included in the new curriculum standard, which is a compulsory course. Primary and secondary schools have to study and take exams, which is linked to the college entrance examination, so the market potential is huge. "There is no strict requirement for pricing here at the headquarters, as long as it is reported in advance, it is not much worse. For example, in Beijing, there are 48 classes a year, and you can receive more than 10,000 yuan within the Fourth Ring Road. If the location is a little bit off, you can receive 8,900 yuan. In addition, it is different between districts, and Haidian is more expensive than Fengtai. "

　　When consulting another children’s programming organization headquartered in Beijing, the staff gave a low threshold for franchisees. "Most of the children’s programming on the market now begins at the age of six or seven. Our courses are specially designed for three to six years old. At this stage, the requirements for teachers are not so high, and kindergarten teachers are professional, which is somewhat similar to early education. Usually the training time is one week, but in the younger stage, two to three days is almost the same. We will provide courseware for teachers and also teach verbal skills. "

　　As for enrollment, the staff said that they can sell small class hours at the entrance of the kindergarten, preferably three or four in-depth audition classes, which is much higher than the conversion rate of free audition classes. "Three to six years old is a huge market. To put it bluntly, it is actually the function of drainage and water storage. When these children grow up, they are likely to learn a higher level of programming, so you are equal to occupying the students in advance. Many students have been taken away by other institutions before they start recruiting at the age of six. " The staff repeatedly stated that the headquarters does not charge the joining fee, but charges a one-time comprehensive service fee. The specific price depends on the city. "For example, there are 300,000 in the north, Guangzhou and Shenzhen, 200,000 in the new first-tier cities, and the lowest county is 135,000. Student fees are also graded. Beijing costs more than 10 thousand a year, and there are 36 classes a year, excluding winter and summer vacations. The cost is lower in the younger stage, and the more expensive it is. "

　　remind

　　Don’t be brainwashed to learn logic without writing code.

　　"At present, children’s programming education in the market has the problem of excessive hype to a certain extent. For children who are still in primary school or even kindergarten, there is actually no need for universal children’s programming education." Zhou Lizhu, a professor at the Department of Computer Science and Technology in Tsinghua University, said that from the perspective of programming learning itself, we should teach students in accordance with their personal interests and characteristics after their mental development is relatively mature. If indoctrination is carried out too early and the method is not scientific enough, it will not be conducive to the long-term development of children.

　　"Some training institutions claim that children can make small games and other works in a short time, and more are just gimmicks for commercial operation. Parents don’t have to blindly follow suit." In Zhou Lizhu’s view, instead of rushing to the so-called children’s programming training class, it is better to lay a solid foundation first. For example, learn Chinese well and shape good expression ability; Learn mathematics well and cultivate strict thinking habits; Learn foreign languages well and adapt to the increasingly open development environment. In addition, it is also very important to establish correct values and have good moral quality, which will affect personal growth more deeply.

　　"It should also be noted that logical thinking and programming are two different things, and the real logical thinking ability is not exercised in writing code." Zhou Lizhu said that programming is only a skill after all, and not everyone has to master it like painting. In order to really improve logical thinking ability, we need comprehensive training in many aspects, rather than simply expecting to get it in programming training.

　　"Some training institutions overemphasize the urgency of learning programming, and continue to develop towards younger age, which brings unnecessary anxiety to many parents. In fact, programming learning doesn’t need and shouldn’t be a competition for all people. Just like the Olympics, it is only suitable for some students who really have this talent and interest. Parents don’t have to blindly follow the trend and are led by the gimmicks made by training institutions. " Chu Zhaohui, a researcher at the China Academy of Educational Sciences, said that at present, the children’s programming training institutions in the market are still immature, the teaching quality is uneven, the industry standards are chaotic, the curriculum system is lacking, and professional teachers are scarce. Parents should be extra cautious when choosing, and relevant departments should also conduct an inventory to eliminate those informal institutions that only want to "make quick money" in time.

　　"The propaganda that some training institutions wantonly link programming with further studies should also be rectified." Chu Zhaohui also said that according to the Advertising Law, advertisements for education and training should not contain explicit or implied guarantee commitments for further studies, passing exams, obtaining degree or qualification certificates, or for the effects of education and training.

　　● Exaggerating and deifying the efficacy of ordinary products makes the audience mistakenly think that there are not a few live broadcasts of health care products, and some anchors imply that they have therapeutic effects when promoting health food. Some buyers listened to the anchor’s propaganda. After buying it back, they found that it was not only ineffective, but also delayed the treatment time.

　　● Anchors who have obtained corresponding qualifications should introduce health care products in a true and accurate way, and should not publicize the contents containing assertions or guarantees indicating efficacy and safety, contents involving disease prevention and treatment functions, or compare with drugs or other health care foods. In addition, it should be suggested that health food can not replace drug treatment.

　　● For businesses selling health care products, the platform should strictly review whether they have corresponding qualifications. If false and exaggerated propaganda behaviors are found, measures such as stopping broadcasting and taking off the shelves should be taken in time; Regulatory authorities need to strengthen daily supervision, severely investigate and deal with illegal and illegal issues such as false and exaggerated publicity of health care products, and publicly expose those with bad circumstances, and include them in personal integrity records according to law, and strengthen joint punishment for dishonesty.

　　"When you associate with people, are you embarrassed because your mouth smells bad? Now there is a hot product ‘ Quiet guardian ’ Candy, made of pure plants and traditional Chinese medicine, can remove oral odor, is safe and has no side effects, and can also regulate the spleen and stomach … …” On a live broadcast platform, an anchor is enthusiastically introducing the product, and specially emphasizes the "spleen and stomach conditioning function" of the product.

　　Some viewers asked, "Can Helicobacter pylori be eliminated?" The anchor replied, "Well, this fan knows what I mean."

　　According to the product details page, this product is bought for 3 and given for 2, which is 88 yuan in total; Buy 2 get 1 free, a total of 58 yuan; 29.8 yuan for a single bottle. The page also introduces the ingredients and efficacy of the product in detail, especially what Helicobacter pylori is, and emphasizes that "the bad prognosis of the disease is gastric cancer".

　　The reporter of "Rule of Law Daily" recently watched many live broadcasts and found that the exaggerated and deified functions of ordinary products made the audience mistakenly think that there were many live broadcasts of health care products, while some anchors directly brought health care foods, such as multivitamin tablets, fish oil capsules, calcium tablets, etc., and implied that their foods had therapeutic effects when introducing them.

　　According to the relevant regulations, goods and services that should be subject to advertising review in advance according to laws and administrative regulations such as medical care, medicines, medical devices, pesticides, veterinary drugs, health foods, formula foods for special medical purposes in online live marketing activities are not suitable for online live marketing.

　　Why are health products popular in the live broadcast room? What is the violation of arbitrarily exaggerating the efficacy of products? How to regulate this phenomenon? With these questions, the reporter conducted an interview.

　　Exaggerate the efficacy of ordinary food

　　Confuse people and deceive buyers.

　　"We are vitamins extracted from compound fruits and vegetables, which are food-grade vitamins without any side effects. If you have hair loss, oily hair, frequent peeling on your hands and feet, poor sleep, etc., you can shoot it directly and you can improve it after eating. "

　　Recently, when Ms. Ou from Shantou City, Guangdong Province brushed the live broadcast, she saw that the anchor was trying to promote a brand of "Blood Orange Compound B Vitamin Chewable Tablets", and the rolling comments in the live broadcast also praised the efficacy of this product. In combination with her love of hair loss, Ms. Ou bought three bottles without hesitation.

　　After receiving the goods, she began to take them according to the instructions, but she began to have a stomachache less than 10 minutes after each meal. "At first, I thought I ate something wrong. Later, I repeatedly confirmed that it was a problem with this vitamin." Ms. Ou said that she went to the brand store to check the relevant comments, only to find that many people commented that they vomited and suffered from abdominal pain after eating the same brand of "multi-vitamin taurine" and went to the hospital for emergency treatment; Others said that they had adverse reactions after taking the "blood orange compound B vitamin chewable tablets" sold by the store, such as stomach pain, breathlessness and allergies.

　　The reporter searched for "health care products" on the live broadcast platform, and the related products of the brand came into view, and many anchors in the live broadcast room were selling the brand products. Moreover, the price of its products is much cheaper than that of products with similar effects sold by regular pharmacies.

　　Take the brand "blueberry lutein ester tablet candy" as an example. The anchor said that "you can use it with too many eyes, and two tablets a day can supplement the required lutein". A total of 144g in 4 bottles only needs 69 yuan; The reporter bought a 30g bottle of health food lutein capsules from a drugstore online, so he had to go to 69 yuan.

　　The reporter noticed that in addition to the above-mentioned products, other products sold by the brand, such as multi-dimensional taurine, vitamin C chewable tablets, nicotinamide chewable tablets and other products, did not bear the logo of "police tactical unit", and the product descriptions did not indicate the health care function and other information. However, when introducing these products, the anchor said that it has the functions of fading spots and acne marks, removing wrinkles, supplementing collagen, reducing hair loss and improving resistance.

　　The reporter asked in the comment area, why these products have so many functions but no "police tactical unit" logo? The other party replied that these products are not health products, but food-grade vitamins or nutritional supplements.

　　It is understood that the package or label of health food must be marked with "police tactical unit". There is an "approval number" under "police tactical unit", such as "national food health word G G××××××××". Moreover, the packaging of health food must indicate the name, net content and solid content, ingredients, effective components, health care function, suitable people, eating method, date marking (production date and shelf life), storage method, implementation standard, name and address of health food production enterprise, and hygiene license number.

　　The standards of health food and general food are also different. The reporter found that the brand’s "blueberry lutein ester tablet candy" only has the food production license number, and the implementation standard number is "SB/TI0347". According to the reporter’s verification, this is the national implementation standard for tabletted candy, and this standard is also applicable to ordinary candy sold in supermarkets.

　　During the interview, the reporter found that there are many similar products that disguise ordinary food as health products and sell them in the live broadcast room, such as Ejiao Bird’s Nest Protoprotein Tablet Candy, Collagen Protein Drink, Probiotic Capsule, Enzyme and Black Lycium barbarum puree.

　　Anchors often use expressions such as "detoxifying and beautifying", "preventing alopecia areata", "regulating the stomach and intestines", "improving immunity", "maintaining healthy eyesight", "relieving skin aging" and "accelerating metabolism" to make consumers mistakenly think that these ordinary foods have special health care functions.

　　If the anchor exaggerates the efficacy of ordinary food and makes consumers mistakenly think it is a health care product, is it illegal to buy it?

　　The reporter interviewed Chen Yinjiang, deputy secretary general of china law society Consumer Protection Law Research Association. Chen Yinjiang bluntly said that this kind of behavior of the anchor is suspected of violating many laws.

　　"If the anchor exaggerates the efficacy of ordinary food and makes consumers mistakenly think it is a health care product, this situation is suspected of false propaganda and infringement of consumers’ right to know and choose." Chen Yinjiang said that the Consumer Protection Law stipulates that operators should provide consumers with information about the quality, performance, use and expiration date of goods or services, which should be true and comprehensive, and should not make false or misleading propaganda; In addition, the Anti-Unfair Competition Law also stipulates that business operators shall not make false or misleading commercial propaganda on the performance, function, quality, sales status, user evaluation, and honors of their products to deceive and mislead consumers.

　　Sell health food at will

　　Suggest a therapeutic effect

　　There are also many anchors selling health care products in the live broadcast room, which is suspected of deliberately exaggerating the efficacy.

　　On a live broadcast platform, an anchor declared when selling the iron health care product of Angelica sinensis and Astragalus membranaceus: "This health care product can replenish qi and blood. If you have bad sleep at night, come to menstruation with little pain, cold hands and feet, and serious hair loss, you can eat it, and you can get obvious improvement after eating for two months."

　　The reporter noticed that anchors selling such health care products usually describe specific conditions when introducing their uses, such as cold hands and feet, difficulty sleeping, hair loss, pale face, confusion in getting up, fatigue and weakness, and clearly indicate that if the above symptoms appear, they can be significantly improved after eating such health care products, thus suggesting the therapeutic efficacy of health care products. However, in the product details page, the health care function of such health care products is only to improve iron deficiency anemia.

　　On another live broadcast platform, an anchor is selling a health care product called ×××× Huangpu Fuling Capsule. This health care product not only bears the "police tactical unit" logo, but also has the batch number of the national food health word.

　　"If you have yellow tongue coating, flatulence, constipation and diarrhea, stomach pain, acid regurgitation, nausea and vomiting, you can take a 6-bottle bottle directly and take it home." The anchor said when introducing the product. Many people commented in the comment area of the live broadcast room that "it is really useful to treat flatulence", "I have a slight gastric mucosal injury, and I feel particularly good after using it for a cycle" and "I feel much better after eating two bottles".

　　The reporter saw on the product details page that the function of the health care product is to help protect the gastric mucosa. However, the anchor introduced in the live broadcast room that the health care product can treat stomach diseases. Because of this, some consumers think that they are buying medicines to treat stomach diseases.

　　Mr. Zhang from Tianjin bought this product in this live broadcast room. At first, when he listened to the anchor’s introduction to the efficacy of the product, he found that it was in line with his symptoms, and he heard that it could be "treated", so he started with 6 bottles. After receiving the goods, he found that he only bought health care products. "Listening to the anchor’s introduction feels like stomach medicine. After eating it, it has no therapeutic effect at all, and it also delayed the treatment and was miserable."

　　The reporter saw in the commodity comment area that there are quite a few people who have similar experiences with Mr. Zhang. Some people commented that "after receiving the goods, they found that it was not a medicine at all, but a health care product", while others said that "the medicine was received soon, it was genuine, and they insisted on taking it, expecting to improve".

　　In addition to the exaggerated efficacy of health care products by the anchor, some Chinese medicinal powders were also emphasized in the live broadcast room.

　　In a live broadcast room, an anchor is promoting a "Ganoderma lucidum spore powder", which said that "this product is Changbai Mountain Ganoderma lucidum+spore powder with a wall-breaking rate of 98%, which greatly enhances immunity. I ate this with a cold and recovered the next day. I will give it to my parents, grandparents and store it. Now immune products are skyrocketing. "

　　Du Leqi, director of the Economic Law Research Society of Jiangsu Law Society and associate professor of Jiangsu University Law School, believes that it is suspected of violating the Food Safety Law and the Advertising Law.

　　"The Food Safety Law stipulates that the contents of health food advertisements shall be true and lawful, and shall not contain false contents, and shall not involve the functions of disease prevention and treatment, and shall state ‘ This product cannot replace the drug ’ ; The Advertising Law also stipulates that, except for advertisements for medical treatment, drugs and medical devices, any other advertisements are prohibited from involving the function of disease treatment, and medical terms or terms that easily confuse the promoted goods with drugs and medical devices are not allowed, and advertisements for health care products are not allowed to involve the function of disease prevention and treatment, and should be clearly marked ‘ This product cannot replace the drug ’ 。” Du Leqi said.

　　Intensify the qualification examination.

　　Strengthen joint punishment for dishonesty

　　If the anchor exaggerates the efficacy of ordinary food or claims that health care products can treat diseases, what responsibility should he bear?

　　Zhao Lijie, a lawyer of Beijing Yinghe Law Firm, said that according to the advertising law, if the anchor has the above misconduct when selling health care products, the anchor or the anchor’s company, as an advertising operator, will face the administrative penalty that the market supervision and management department will confiscate the live advertising expenses and impose a fine of more than one time but less than three times the advertising expenses. If the circumstances are serious, it will be fined more than three times and less than five times the advertising expenses. If the advertising expenses cannot be calculated or obviously low, it will be fined more than 200,000 yuan and less than one million yuan, and it can be suspended by the relevant departments.

　　Du Leqi added that if the anchor has the above misconduct, it may also involve the civil liability risk of infringing on the legitimate rights and interests of consumers. According to the Consumer Protection Law and other laws and regulations, if a merchant deceives or misleads consumers, and the products or services provided are inconsistent with the live online shopping contract, which infringes on the legitimate rights and interests of consumers, it shall be liable for breach of contract such as repair, rework, replacement, return, refund and compensation for losses. If the anchor makes a commitment to the product or service during the live broadcast, it should also bear joint liability with the merchant within the scope of the commitment.

　　"The anchor should initially verify the product information, avoid false propaganda, and try to avoid recommending special products. It can entrust a professional lawyer to review, improve the cooperation contract with the brand and pay taxes according to law. According to the provisions of the Advertising Law, advertising spokespersons should make recommendations and certificates for commodities and services in advertisements based on facts and in accordance with the provisions of this Law and relevant laws and administrative regulations, and may not make recommendations or certificates for their unused commodities or services. In addition, the anchor should pay attention to the compliance of advertising language during live broadcast and put an end to false propaganda. " Du Leqi said.

　　Chen Jiangyin also reminded that anchors who have obtained corresponding qualifications should introduce the relevant information of health care products truly and accurately, and should not publicize the contents that contain assertions or guarantees indicating efficacy and safety, and cannot publicize the contents that involve disease prevention and treatment functions, nor can they be compared with drugs or other health foods. In addition, it should also be suggested that health food can not replace drug treatment.

　　The reporter found that in recent years, people’s awareness of health care has been continuously enhanced, and more and more people have begun to favor health care products. So, what should consumers pay attention to when buying health care products?

　　Zhao Lijie suggested: First of all, when purchasing health care products, consumers should keep a correct attitude and clearly realize that health care products are food, not drugs. If they want to treat diseases, they should follow the doctor’s advice; Secondly, when purchasing health food, we should recognize the "police tactical unit" logo and registration number/record number of health food on the product packaging, and make scientific choices according to the health function of health food, suitable people and unsuitable people, and don’t blindly believe the recommendation and introduction of the anchor or offline sales staff; Third, go to legal offline stores or online official flagship stores to buy, pay attention to check their food business licenses, and ask for invoices or sales credentials.

　　In view of the chaos in the sales of health care products in the current live broadcast, Chen Jiangyin believes that the consumption of health care products is related to the life, health and safety of consumers and must be paid enough attention by all parties.

　　"For the merchants selling health care products, the platform should strictly review whether they have corresponding qualifications, such as whether the merchants have food business licenses or medical device business licenses; Strengthen daily supervision. If false and exaggerated propaganda behaviors are found, measures such as stopping broadcasting and taking off the shelves should be taken in time and reported to the relevant regulatory authorities. The anchor should strictly abide by the relevant laws and regulations, introduce the information of health care products truly and accurately, and must not publicize the efficacy of health care products to deceive and mislead consumers. The regulatory authorities should strengthen the chaos management of live broadcast of health care products with goods, intensify joint interviews, joint law enforcement, joint exposure and joint punishment, and severely investigate and deal with violations of laws and regulations such as false and exaggerated propaganda of health care products. If the circumstances are bad, they should be publicly exposed and listed in personal integrity records according to law, and strengthen joint punishment for dishonesty. " Chen Jiangyin said.

　　Zhao Lijie believes that in order to rectify the chaos of live health care products and further create a good environment for live health care products, in addition to the concerted efforts of platforms, anchors and relevant departments, consumers should also make rational shopping, and do necessary research and screening on platforms and products before placing orders. Don’t trust the introduction and promotion of platforms and anchors, and don’t blindly place orders.

China Net News April 17 (Reporter Hu Yongping) The noisy acquisition of Wanjia Culture by Zhao Wei and his wife finally came to fruition after a lapse of nearly half a year. On April 16th, the CSRC issued the Decision on Administrative Punishment and the Decision on Market Prohibition in official website, ordering Wanjia Culture and Longwei Media to make corrections, giving them a warning and imposing a fine of 600,000 yuan respectively. Kong Deyong, Huang Youlong, Zhao Wei and Zhao Zheng were given warnings and fined 300,000 yuan respectively. Huang Youlong, Zhao Wei and Kong Deyong were banned from the securities market for five years respectively.

This time, the CSRC issued the official Decision on Administrative Punishment. It has been five months since November 2017, when Wanjia Culture (renamed Xiangyuan Culture) received the Notice of Administrative Punishment and Market Prohibition from the CSRC. During this period, Zhao Wei and Huang Youlong filed a defense with the CSRC.

The punishment decision of the CSRC published the arguments of Huang Youlong and Zhao Wei in detail and refuted them one by one.

According to the facts, nature, circumstances and social harm of the parties’ illegal acts, and according to the provisions of the first paragraph of Article 193 of the Securities Law, the CSRC decided to order Wanjia Culture and Longwei Media to make corrections, give them a warning and impose a fine of 600,000 yuan respectively; Kong Deyong, Huang Youlong, Zhao Wei and Zhao Zheng were given warnings and fined 300,000 yuan respectively.

The decision also states that the above-mentioned parties shall remit the fine to China Securities Regulatory Commission within 15 days from the date of receiving this penalty decision. If a party refuses to accept this punishment decision, he may apply to China Securities Regulatory Commission for administrative reconsideration within 60 days from the date of receiving this punishment decision, or bring an administrative lawsuit directly to the people’s court with jurisdiction within 6 months from the date of receiving this punishment decision. During the period of reconsideration and litigation, the above decision shall not be suspended.

The five-year ban means that during these five years, Mr. and Mrs. Zhao Wei and Mr. Huang Youlong may not continue to engage in securities business in the original institution or serve as directors, supervisors or senior managers of the original listed company, nor may they engage in securities business in any other institution or serve as directors, supervisors or senior managers of other listed companies.

Securities and Futures Commission points out "five sins" of Longwei Media:

1. Longwei Media’s acquisition of listed companies by shell companies and its hasty announcement have seriously misled the market and investors under the circumstances that the funds in its own territory are insufficient and the financing of relevant financial institutions has yet to be approved, and there is great uncertainty.

The acquisition requires a total of 3,059.9 million yuan. In the acquisition plan, Longwei Media has its own funds of 60 million yuan, and the remaining funds are borrowed, with a leverage ratio of 51 times. Only after the signing of the Share Transfer Agreement did Longwei Media negotiate financing with the relevant banks, and the financing funds of this bank need to be approved by the head office, and there is still uncertainty whether it can be finally approved.

Longwei Media was established one month before the acquisition. During this period, the funds were not fully prepared. Under the circumstances that the funds payable in China were limited and the funds to be incorporated by financial institutions were not fully prepared, it adopted a highly leveraged acquisition method and signed an equity transfer agreement. In the case that the performance ability and performance results are not exact, and the authenticity and accuracy of the acquisition behavior cannot be guaranteed, the acquisition information is rashly announced. Due to the superposition of celebrity effect and other factors, its behavior seriously misled the market and investors, aroused great concern from the market and the media, and caused the stock price of Wanjia Culture to fluctuate greatly, seriously disrupting the normal market order.

2. There are false records and major omissions in the information disclosure of Longwei Media about the financing plan and arrangement.

Longwei Media said in its reply to the inquiry letter on January 12, 2017 that it pledged financing of 1,499.9 million yuan to financial institutions, and the disclosed financing amount was inconsistent with the actual situation that CITIC Bank planned to provide financing of 3 billion yuan to Longwei Media.

The payment method disclosed by Longwei Media in its reply to the inquiry letter on January 12, 2017 is a definite step and a definite amount, but it is not completely disclosed that the payment method will be adjusted with the approval of financial institutions.

Longwei Media did not specify the huge uncertainty of financing of financial institutions in the announcement, and there were major omissions.

3. Longwei Media did not disclose the failure to reach financing cooperation with financial institutions in time.

On January 12, 2017, Longwei Media said in its reply to the inquiry letter of Shanghai Stock Exchange through Wanjia Culture that the approval process for stock pledge financing of financial institutions is expected to be completed before January 31, 2017. The evidence shows that on January 23, 2017, Wanjia Group and Longwei Media knew that their financing plan to CITIC Bank Hangzhou Branch had not been approved by CITIC Bank Head Office. As of January 31, 2017, Longwei Media has not reached a financing cooperation with any financial institution.

4. Longwei Media has made major omissions in the disclosure of the reasons for failing to complete the financing plan on schedule.

Longwei Media attributed the failure to complete the financing plan on schedule to the failure of financing approval of financial institutions in the announcement disclosed by Wanjia Culture on February 16, 2017. It did not disclose the fact that Yinbixin did not prepare enough funds when the second equity transfer payment should be paid, and there were major omissions.

5. Longwei Media’s information disclosure about actively promoting the successful completion of this transfer of controlling interest has false records and misleading statements.

On January 12, 2017, Longwei Media said in its reply to the inquiry letter of Shanghai Stock Exchange through Wanjia Culture, "If Longwei Media fails to obtain the stock pledge financing of financial institutions in time and in full, Longwei Media will actively communicate with Wanjia Group to make this transaction complete smoothly, and continue to seek the stock pledge financing of other financial institutions."

The evidence shows that Longwei Media did not actively communicate with Wanjia Group and did not contact other financial institutions to seek financing after the approval of CITIC Bank failed, and there were false records and misleading statements in information disclosure. According to Kong Deyong’s inquiry record, Longwei Media did not actively communicate with Wanjia Group after the financing approval of CITIC Bank failed. On February 7, 2017, Huang Youlong sent Zhao Zheng to directly discuss with Kong Deyong about the termination of the acquisition of the controlling stake. At the same time, Huang Youlong, Zhao Zheng and others also said that after the financing plan of CITIC Bank was not approved, Longwei Media had no contact with other financial institutions.

　　It is reported that Krypton was listed on the New York Stock Exchange a year ago, setting a new record for the fastest listing in the history of new energy vehicle companies. By September, 2024, Geely officially issued the Taizhou Declaration, which includes five measures: strategic focus, strategic integration, strategic coordination, strategic stability and strategic talents. It is planned to form Geely Automobile Group and Krypton Technology Group, two major automobile business entities, in the passenger car sector.

PAData Insight：

This year, blockchain security incidents have occurred more than 10,000 times, and the cumulative global losses have exceeded 6 billion US dollars.

Among digital asset crimes, the United States accounts for 28%, which is the largest in the world, Europe accounts for 24% and China accounts for 18%.

This year, there have been more than 28 exchange security incidents, of which more than 7 have been stolen from exchange digital assets.

More than 100 smart contract vulnerabilities have accumulated losses of more than 10 million US dollars, of which EOS DApp attacks have exceeded 60 at most, accounting for 67%.

There were more than 7 wallet security incidents in the whole year, with losses exceeding 100 million RMB.

Digital currency, which has the largest traffic of bitcoin in the dark network this year, has a total transaction value of about $1.035 billion.

This year’s cyber blackmail attacks caused losses of up to $1.5 billion, up 20% year-on-year, and various fraud crimes are still rampant.

Security has always been a hot issue in the industry. According to Chengdu Chain Security Report, in 2019, blockchain security problems caused by blockchain digital assets showed an overall upward trend, and security incidents caused by various reasons also increased significantly. There were various crimes in digital currency, including money laundering, fraud, theft, drug trafficking and mining crimes. Due to the poor security of digital currency trading platform and the complex data structure and algorithm, the work efficiency is low, especially the irregular operation behavior, which hinders the development of digital currency.

In security incidents, the project party runs away and involves the most funds.

The United States became the hardest hit area for digital asset crimes in 2019.

According to Chengdu Lian ‘an statistics, in 2019, the United States accounted for 28% of digital asset crimes, with Europe accounting for 24%, followed by China accounting for 18%. According to statistics, from January 2019 to mid-December 2019, there were more than 10,000 hacking incidents of digital assets around the world, and there were as many as 2,000 criminal cases related to digital assets in China.

In 2019, criminal means emerged in an endless stream, ransomware and money-plate running patterns were newly turned over, criminal gangs came from a wide range, and the number of criminal cases and the total amount involved in criminal activities showed an increasing trend.

In 2019, the types of global digital asset crimes include hacking, money-raising, money laundering, and illegal transactions in secret networks, with a total loss of more than 6 billion US dollars. The amount involved in cyber crimes and secret network transactions is roughly the same, and the amount involved in the project’s road running is more than twice that of the first two, of which the loss caused by system loopholes exceeds 1 billion US dollars.

In terms of hacker attacks, assets are stolen mainly for five reasons, namely, exchange loopholes, smart contract loopholes, wallet loopholes, public chain loopholes and improper use by users.

In 2019, there were more than 28 exchange security incidents.

More than 70% of digital assets were stolen.

In 2019, there were more than 28 exchange security incidents, among which more than 70% became the theft of exchange digital assets. From January, the Cryptopia exchange was hacked twice, and the stolen ETH and ERC20 currency tokens lost more than 16 million US dollars. On November 27th, 340,000 ETH was stolen from South Korea’s Upbit exchange, with an estimated loss of more than 49 million US dollars. The rest included the escape of the exchange, information leakage of the exchange and other asset losses, with a total loss of more than $1.3 billion.

On the morning of May 8, 2019, the official of Qian ‘an issued a notice saying that "large-scale security vulnerabilities" were found in the system. Hackers used composite technologies, including phishing and viruses, and stole 7,000 bitcoins from Qian ‘an Hot Wallet at a block height of 575,012. Causing the exchange to lose $41 million.

On November 27, 2019, the UpBit security system of the Korean exchange was destroyed and 34,200 ethereal coins were stolen. Causing the exchange to lose more than 50 million US dollars.

More than 100 smart contract vulnerabilities have accumulated losses of more than 10 million US dollars.

There are more than 60 EOS DApp attacks, accounting for 67%.

In 2019, the number of DApp continued to increase. According to statistics, as of the beginning of December, the total number of DApp currently running on public chains such as ETH, EOS and Wave Field exceeded 3,000, and there were more than 100 smart contract vulnerabilities this year, most of which were hacked in EOS DApp. Up to now, the total loss of DApp was over 10 million US dollars.

There are over 60 typical attacks on EOS public chain this year, and the concentrated outbreak period is from January to April, accounting for 67% of the attacks in the whole year. The main reason is the continuous popularity of spinach applications on EOS public chain and the weak security of project contract code, which leads hackers to continuously attack the same vulnerability on multiple DApp. The main methods are transaction blocking, rollback transaction attack, fake EOS attack, random number cracking and so on.

There have been nearly 20 typical attacks on the TRON public chain this year, mainly in April, May and July, with small-scale attacks as the main method and rollback transactions as the main method.

There has been no serious DApp attack on the ETH public chain this year. First, the number of spinach quiz contracts on the ETH public chain is small, and the popularity is not enough. Second, the ETH smart contract project is relatively perfect in terms of security.

There were more than seven wallet security incidents in 2019.

June is the high incidence period of wallet security incidents.

Due to the low entry threshold and poor security, in the absence of supervision, wallet security problems have broken out repeatedly, and it is easy to break out with huge sums of money. At present, there are many hidden dangers in wallet security, including the forgery of wallet APP, the failure to detect weak password in transaction password, the failure to reinforce the core code, the failure to detect the running environment of the system, and the existence of screen capture and recording records in operation.

Since at the beginning of June this year, the wallet GateHub broke out that it had been stolen by more than 23 million XRP, and there were more than 7 wallet security incidents in the whole year, with a loss of over 100 million RMB.

On October 11th, the cryptocurrency wallet ZenGoCEO Ouriel Ohayon tweeted that Safuwallet, a web cryptocurrency wallet, had been stolen by hackers by injecting malicious code.

From August to September, the bitcoin wallet Electrum was attacked by hackers twice. According to many statistics, the phishing attack that forged Electrum upgrade tips has stolen at least 1,450 BTCs, worth 11.6 million US dollars.

There have been more than 8 public chain safety incidents.

More than half of them are 51% attacks, and small and medium-sized public chains are even more threatened.

In 2019, there were more than 8 attacks on public chains, more than half of which were 51% attacks, which reduced the frequency of attacks compared with 2018, resulting in less losses.

Among the public chain attacks, on January 5th, ETC was attacked by 51% for many times, and 80,000 ETCs were used for double flowers. On August 9, hackers launched a "dust attack" on Litecoin, and the affected addresses reached 294,582. At present, it is almost impossible for large enough public chains such as BTC and ETH to be attacked by 51%. All non-large public chains and some small public chain currencies should be careful of the threat from 51% attacks.

When dealing with 51% attacks, we should try our best to keep the computing power scattered. Overconcentrated computing power is the direct cause of 51% attacks. On the basis of Satoshi Nakamoto’s consensus, 51% attacks theoretically exist forever. We should set up a sound early warning mechanism for risk control and adopt a good defense mechanism for exchanges. In case of 51% attacks, we can increase the number of block confirmations, suspend the withdrawal of money, freeze suspicious accounts and other measures to avoid losses in time.

In 2019, the overall safety awareness of users increased.

Improper use by individual users causes asset losses.

In 2019, the overall users’ security awareness increased, and some users still suffered asset losses due to improper operation of wallet private keys and access to phishing websites.

In 2019, Bitcoin became the digital currency with the most traffic in the dark network.

The total transaction value in the whole year was about $1.035 billion.

In 2019, the dark net is still an illegal place for cyber crimes, trading by taking advantage of digital currency’s anonymity to avoid supervision. In the whole year, 1.035 billion dollars worth of bitcoin has been used for illegal activities. The largest category of bitcoin traded in the dark net is drugs, and bitcoin is also the most popular digital currency, followed by Litecoin.

There are many kinds of illegal goods sold in the dark net, mainly involving data, information, illegal software, arms, drugs, etc., and criminals choose digital currency as the trading currency, for example:

In 2019, more than $5 billion in money laundering cases were investigated.

Among them, Bitcoin is the preferred money laundering tool.

In the money laundering cases investigated in 2019, more than 5 billion US dollars were conducted through cryptocurrency, among which Bitcoin was the first choice for criminals to launder money. Digital currency has become an important tool for criminals to launder money around the world. At present, there are 100-200 gambling sites companies in the world that can use digital currency to pay for gambling. Criminals open accounts on these websites, then transfer funds into accounts, engage in some small-scale gambling, and some even do not gamble, and then withdraw money to a new address to achieve the purpose of money laundering.

In 2019, cyberblackmail attacks caused at most $1.5 billion in losses.

All kinds of fraud crimes are still rampant.

Cybercrime includes fraud, extortion, and the destruction of related blockchain service providers. Criminals take advantage of the anonymity of Bitcoin, choose Bitcoin as ransom more frequently, and conduct extortion activities through ransomware or some other illegal means.

In 2019, the cyber extortion attacks caused a loss of $500-150 million to the world, which was 20% higher than last year. The criminal activities of extorting and extorting digital currency have been continuous, even increasing. In addition, this year is still a year of rampant fraud crimes, and all kinds of online fraud incidents still account for a large proportion of online criminal activities. Typical cases are as follows:

The project party’s running involves more than 25 billion yuan.

Plustoken wallet running event involves 20 billion yuan.

In 2019, among the many events of capital plates, pyramid schemes, wallets and exchanges, the most notable event was the incident of Plustoken wallet running on June 29th. On that day, many users reported that Plustoken wallet could not be withdrawn, and the project party of Plustoken wallet was suspected of running, and the amount involved may exceed 20 billion yuan. As of the beginning of December, the blockchain project that ran this year involved more than 25 billion yuan.

The difficulty of mining increases and the income decreases.

Malicious illegal mining indirectly causes social losses.

Power consumption is the main cost of mining, and it is also the key to determine the benefits of mining. With the increasing difficulty of mining, the benefits of normal mining have become lower and lower, and many people have played the wrong idea of illegal mining. Illegal means of mining-Mining Trojans get rewards from digital currency system by completing a large number of calculations. Mining Trojans and worms will occupy a lot of CPU and GPU resources of the computer in the process of calculation, which will cause the computer to become abnormally slow, interfere with the normal system operation, and spread at a high speed, causing great impact and loss to government agencies and enterprise services.

More than 5 typical information leakage incidents in the whole year.

User’s personal data has great hidden dangers due to centralized operation mode.

In mid-2019, a total of more than five typical information leakage incidents were reported. Because many exchanges and wallets are still centralized, it is inevitable to store users’ personal data. Once attacked, hackers may obtain a large number of user data, and sell data through dark networks and other means to obtain huge profits.

Summary and suggestions

Digital currency is widely used for handling fake passports, providing pornographic services, transferring illegal assets, buying and selling drugs and underground arms, which will disrupt social order, pose a threat to the stable development of society, and will also affect the development of enterprises operating normally in the industry, which is undoubtedly extremely harmful to the whole digital currency industry, the financial industry and the whole society.

From the system architecture, related enterprises and professional blockchain security research should organize cooperation to find and fix system vulnerabilities in time to avoid serious large-scale fund theft. Managers of enterprise websites and server resources should deploy enterprise-level network security protection systems to prevent enterprise servers from being invaded and installed with mining viruses and from being infringed by blackmail viruses.

For netizens who participate in digital virtual currency trading, they should fully understand the possible risks and use security software on the computer and mobile phone to avoid falling into the phishing trap and avoiding the theft of digital virtual currency wallets.

For ordinary netizens, computer poisoning should be prevented from becoming a controlled "miner", and game plug-ins, cracking software and video website client cracking tools should be used cautiously, which are more likely to be artificially implanted with malicious programs. For virtual currency, we should guard against speculation.

CCTV News:On July 20, the State Council held a press conference on promoting the development and growth of the private economy. Xu Xiaolan, Vice Minister of the Ministry of Industry and Information Technology, introduced that the Ministry of Industry and Information Technology has focused on the following aspects:

First, focus on improving the rule of law environment. In-depth implementation of the Law on the Promotion of Small and Medium-sized Enterprises to promote the introduction of supporting regulations, this year marks the 20th anniversary of the promulgation and implementation of the Law on the Promotion of Small and Medium-sized Enterprises, and at present, 27 provinces (cities) have issued regulations on the promotion of small and medium-sized enterprises in their own regions. Carry out in-depth work to clean up the accounts owed to small and medium-sized enterprises and protect their legitimate rights and interests.

The second is to improve the policy environment. We promoted the introduction of a series of policies, such as "Several Measures to Help Small and Medium-sized Enterprises to Stabilize Growth and Adjust Their Structural Strength". Last year alone, more than 40 policies were issued at the national level to support small and medium-sized enterprises, which led to more than 270 supporting policy documents issued at the provincial level. At the same time, we earnestly implemented policies, compacted all responsibilities, and effectively allowed small and medium-sized enterprises to enjoy policy dividends.

The third is to continuously optimize the innovation environment. We have carried out the "three taxes" special actions of digital empowerment, scientific and technological achievements empowerment and quality standard brand assignment for small and medium-sized enterprises to enhance their core competitiveness. Cultivate small and micro enterprises’ entrepreneurial innovation demonstration bases and small and medium-sized enterprises’ characteristic industrial clusters, build innovation carriers and gather innovative resources in all aspects. Improve the gradient cultivation system of high-quality small and medium-sized enterprises, and stimulate the emergence of more specialized and innovative small and medium-sized enterprises.

The fourth is to continuously improve the financing environment. Promote banking financial institutions to increase credit supply to small and medium-sized enterprises, promote new models such as loan-with-loan and loan-with-loan, and promote the incremental expansion of inclusive small and micro enterprise loans. Focus on key industrial chains and carry out the financing promotion action of "one chain, one policy and one batch" for small and medium-sized enterprises. Support the listing and financing of specialized and innovative small and medium-sized enterprises, give play to the guiding role of the national small and medium-sized enterprise development fund, and drive more social capital to invest in early investment and small investment innovation.

The fifth is to speed up the construction of an efficient service system. Promote the initial formation of a service system for small and medium-sized enterprises, with nearly 1,700 public service institutions for small and medium-sized enterprises at the national, provincial, municipal and county levels as the backbone, more than 3,800 service demonstration platforms at or above the provincial level as the support, and a large number of social service institutions as the supplement. In the first half of the year, there were more than 7 million service enterprises of various service organizations nationwide.

In order to further promote the optimization of the development environment of small and medium-sized enterprises in various places, the Ministry of Industry and Information Technology, in accordance with the legal requirements of the Law on the Promotion of Small and Medium-sized Enterprises, has regularly carried out third-party evaluation of the development environment of small and medium-sized enterprises since 2019, covering 36 key cities across the country, and the effect of "promoting construction by evaluation, promoting reform by evaluation, and promoting Excellence by evaluation" has gradually emerged. In the next step, the Ministry of Industry and Information Technology will continue to improve the work system, policies and regulations system and quality service system from the above five aspects, continuously optimize the development environment, and create a market-oriented, legal and international business environment for small and medium-sized enterprises.

Build a safe water supply barrier to ensure that water is safe.

The continuous high temperature and rainless weather has caused the city’s drought prevention and relief work to face a severe situation. The Municipal Flood Control and Drought Relief Headquarters issued a circular, and at 9: 00 on August 14, the city-wide level IV emergency response was launched.

Yesterday, the reporter learned from Liuyang Economic Development Zone Water Company that the daily water supply of the park has been rising since the dog days. On August 16th, the water consumption reached 178,000 tons, nearly 10,000 tons more than the highest daily water consumption last year, and the water demand is still rising.

"People’s livelihood is no small matter. In any case, we must guarantee the production and living water of Yangxin City enterprises and residents." Zhang Juanjuan, chairman of Liuyang Economic Development Zone Water Company, stressed many times when deploying the summer peak water supply work.

Ensure water supply, maintain equipment operation, strengthen inspection of production equipment, encrypt the frequency of water quality inspection, strengthen water purification treatment, and advocate water conservation … Since June, Liuyang Economic Development Zone Water Company has arranged a number of measures in advance around the summer peak water consumption to ensure that enterprises can use water without worry.

Liuyang Rong Media Center reporter Zhang Yonghong correspondent Li Ning

Steady supply

Strengthen the inspection of water supply equipment to ensure water supply.

At 4 o’clock on the afternoon of August 16th, Jinyang No.1 Water Plant, the hot sun was roasting the earth, the outdoor temperature was as high as 38℃, and the heat waves burst. The staff of the water plant were busy inspecting the production equipment.

Water plants, water pumps, motors, hydraulic valves, frequency converters … The more water supply equipment and supporting facilities there are, the longer they stay. In the sauna-like working environment, the mind of the staff remains highly awake and carefully checks every screw and dial.

According to the relevant person in charge of Liuyang Economic Development Zone Water Company, in order to ensure a smooth water supply peak, four water plants in Jinyang New City have been started simultaneously, and Jinyang No.1 Water Plant is close to full capacity.

"The temperature is high, the equipment runs for a long time, and the heat dissipation is not enough, which is easy to break down. In order to find and solve problems in advance and avoid failures, we have increased the number of inspections and increased the maintenance of equipment. " According to the person in charge, in order to ensure the normal and safe operation of the equipment, at present, the four water plants strictly implement the 24-hour duty inspection system, and the duty personnel conduct inspections every 2 hours. For inspection workers, high-temperature roasting and indoor "sauna" have become commonplace, and they walk nearly 20,000 steps a day.

Water quality preservation

Take samples every hour to ensure the safety of water quality.

In the continuous high temperature weather, the water level of Laodao River is reduced, the flow rate is reduced, and the flow velocity is slow. Floating objects, fallen leaves and dead branches in the river flow to the intake, which may cause the intake grille to be blocked and affect the quality of raw water.

On the afternoon of August 16th, Huang Youtong, Luo Qingjun, Deng Jie, Li Chengquan and others, the staff of No.1 Water Plant of Liuyang Economic Development Zone Water Company, came to the river to prepare to go down the river to clean up the sundries near the water intake. They change their work clothes and put on life jackets. A straw hat, a rake and a pair of hands are all their "equipment".

Bend over, salvage, get up … They kept repeating these actions in the hot sun, and the boat was gradually filled with debris. After more than 20 minutes, the water surface near the water intake finally became clean and unobstructed.

"Ensuring smooth water intake is the basis for normal water supply during peak hours." Huang Youtong said that during the dry season, they have to clean up every two days or so.

In order to ensure the continuous and stable water quality of water supply in hot weather, Liuyang Economic Development Zone Water Company has also increased the frequency of testing. Samplers sample and test source water, factory water, pipe network water and terminal water once every hour to keep abreast of water quality changes.

In addition, the water plants of the water company have also organized staff to clean the process tanks such as sedimentation tanks and filter tanks for many times to ensure the cleanliness of the process tanks and avoid the influence of sediment deposition on the water treatment process effect and water supply quality.

Excellent service

The maintenance team is on standby 24 hours a day to solve the water problem in time.

On the afternoon of August 15th, some people reported that a water supply supervisor in Yongtai Road had a water leakage problem. In order to avoid the impact of water stoppage and maintenance during the daytime peak period on the water consumption of enterprises and residents, the maintenance team of the business service center of Liuyang Economic Development Zone Water Company worked overtime at night for emergency repair, and the water pipe maintenance was completed at midnight.

In order to deal with water pipe leakage and other problems in time, maintenance personnel are on standby 24 hours a day, fighting for maintenance in such a hot and humid working environment as a narrow water meter well.

As hot as the hot weather at present, there is also the service enthusiasm of the staff of the business service center of Liuyang Economic Development Zone Water Company. The person in charge of the business service center said that during the peak period of water use, the number of water consultation and repair calls also increased sharply. In order to ensure the water demand of residents in Jinyang New Town and practice the practical requirements for the people, the staff of the service center patiently answered all kinds of water-related consultation and repair calls, recorded and classified the relevant information, and timely fed it back to the relevant departments of the company to ensure that every problem could be accepted in time.

"If there is a water problem, residents of Jinyang New Town can call our 24-hour service hotline at any time, and we will do our best to provide services." According to the person in charge, the service hotlines are 0731-83280619, 8322002 (Liuyang Economic Development Zone), 0731-83202583 (Yongan Town), 0731-8324715 (Jiaoxi Town) and 0731-83280658 (Dongyang Town).

These days, friends, friends and WeChat groups can always see everyone’s concern about nucleic acid detection and discuss the COVID-19 epidemic. Since then, nucleic acid detection has become a high-frequency word. But do you really know about nucleic acid testing? What is the nucleic acid strategy under the most severe and complicated situation faced by Chongqing since the COVID-19 epidemic?

In this issue of "Knocking on the Blackboard", Xiaobian will focus on these issues.

The role of nucleic acid detection—It is recognized by the medical communityThe "Gold Standard" for Diagnosing Covid-19

Why do you want to do nucleic acid testing? On November 27th, at the 150th press conference on the prevention and control of COVID-19 epidemic in Chongqing held by Chongqing Municipal Government Information Office, Li Pan, deputy director of Chongqing Municipal Health and Wellness Committee, once again stressed clearly:

Nucleic acid detection is the "gold standard" recognized by the medical community in diagnosing Covid-19. It is an important measure to quickly find infected people, lock the source of infection in time, and quickly cut off the route of transmission. It is a key measure to realize early detection, early reporting, early isolation and early treatment.

(Related links: press conference, responding to concerns-will you be infected in the process of making nucleic acid? What is the difference between regional nucleic acid and expanded nucleic acid?)

At the 147th press conference on November 22nd, Luo Fei, an expert from Chongqing CDC, made an analogy.

If antigen testing is an auxiliary team and nucleic acid testing is the main player; antigen testing is an attack by innuendo, then nucleic acid testing is the final word.

(Related links: press conference, responding to concerns-which is more useful, antigen or nucleic acid? Is the nucleic acid test result true?)

From a professional point of view, the positive result of nucleic acid detection can be regarded as the same as the result of virus culture and then detection. Covid-19 nucleic acid detection is to select two or three characteristic sequences on the virus genome, copy and amplify them, and then detect and compare them, which is what we often call double-target or triple-target detection.

Because the conservative gene sequence of virus is usually selected as the target gene in nucleic acid detection, even if the virus mutates, it has little effect on the detection ability. Nucleic acid detection requires high detection reagents, detection facilities and equipment, and requires professionals to complete more complicated processes such as collection and detection.

---

• Xiaobian analogy-
• Nucleic acid testing is like "raising a baby chicken". When the chick is very young, most people can’t see the male and female, but when the chick is raised, you will know it when you look at the comb.
• Why does it take several hours for nucleic acid testing to produce results? In fact, it is to cultivate viruses, or to raise chickens. Covid-19 nucleic acid detection is equivalent to using cockscomb as a feature to identify male and female, which is the so-called "target gene". At the same time, it is not easy to misjudge if it is characterized by cockscomb, but it is easy to misjudge if it is characterized by chicken feet and tail, so cockscomb is the so-called "conservative gene".

---

At the 151st press conference on November 27th, Liao Pu, director of the Laboratory Department of Chongqing People’s Hospital and deputy director of Chongqing Clinical Laboratory Center, also explained the nucleic acid detection.

(Related links: Why is nucleic acid detection the "gold standard"? What about "false yin" and "false yang")

At present, Covid-19 nucleic acid detection usually uses fluorescence PCR amplification technology, and its principle is that viral nucleic acid is increased exponentially through one cycle, so as to realize Covid-19 nucleic acid detection. This is a very classic and reliable nucleic acid detection method, and it is a technology that won the Nobel Prize.

In the detection process, the yin and yang of the detection results are objectively judged by the circulating threshold of nucleic acid amplification, that is, Ct value. The Ct value is related to the viral load of the infected person. The lower the Ct value of the infected person, the higher the viral load of the infected person. Conversely, the higher the Ct value, the lower the viral load of the infected person.

For the report of positive results, according to the detection strategy, one or two other nucleic acid detection reagents that are more sensitive and amplify different regions will be used to detect the original samples when necessary, and the positive results will not be reported until they are confirmed, so sometimes the detection time is longer.

Although nucleic acid detection technology is the recognized gold standard in Covid-19, it is an internationally recognized detection technology for mature pathogens. However, the so-called "false negative" may appear in unreasonable sample collection, transportation and processing, too low virus droplets in the sample, variation of the target sequence to be detected or sequence change caused by other reasons.

For sudden and new subtype Covid-19, such as Omicron mutant, which has the characteristics of concealment, the optimal sampling time for detection may not be confirmed. In addition, in the process of sample collection and detection, pollution caused by aerosol will occur, resulting in false positive. By strengthening laboratory quality control, monitoring laboratory environment and equipment pollution, and multiple rounds of nucleic acid screening, we minimize the errors caused by technical reasons.

Strategies for nucleic acid detection-different strategies at different stages according to the needs of epidemic situation.

These days, users always leave messages asking questions. Why do you do nucleic acids in different areas?

Indeed, since November 1, especially since November 12, when the coordinated prevention and control of the central city was carried out and the epidemic annihilation war was launched, the Chongqing epidemic prevention and control headquarters adopted different nucleic acid detection strategies at different stages according to the needs of the epidemic situation.

For example, the social inspection has been carried out once every seven days, once every day and every other day. After the city launched the social clean-up attack, according to the deployment of classified attack, all districts and counties were divided into three categories: relatively stable epidemic situation, fluctuating platform period and severe situation, to carry out nucleic acid testing.

Li Pan spoke carefully at the press conference on the evening of November 26th. Under the provisions of the ninth edition and Article 20, various localities will formulate different strategies according to the situation of this area, street, community and even community. Specific to this round of epidemic in Chongqing:

At the beginning of the epidemic, the central city of annihilation was fought-

The epidemic situation is multi-point, multi-source and multi-chain. I don’t know where the potential infected people are, and the chain is unclear. For example, "I don’t know where the’ enemy’ is", then take the whole central city as a whole and carry out nucleic acid testing all over the region, and do it every day, which is to find out the potential infected people. After searching for a period of time, I marked a high-risk area.

Fight the tough battle in the central city in the stage of social clearing-

At this time, it is: high-risk areas should be zoned quickly, and nucleic acid testing should be carried out at the specified frequency in high-risk areas; in other areas, because there is still community transmission, it is necessary to "check every other day" and strive to promote social clearing.

Yuzhong, Jiulongpo, Jiangbei and Yubei made three rounds in three days-

Li Pan said at the press conference on the evening of November 26th that the epidemic situation in all districts of the central city was divided, and some districts added thousands of people a day, with a high proportion of society.

Therefore, just like the annihilation war at the beginning of the epidemic, Yuzhong District, Jiulongpo District, Jiangbei District and Yubei District decided to make three rounds in a row for three days, and continue to exert their strength and concentrate their efforts to find out the potential infected people and the risk sources in a short time.

Similarly, the same is true of Liangping, Dianjiang and Xiushan. The difference is that it is not the whole district (county), but the streets where the county is located and the streets involved in the epidemic.

Xiaobian said so much, we can see that the nucleic acid strategy must be a specific arrangement made according to the current epidemic situation. It is about strategy and actual situation. I hope parents will understand and support it.

Organization of nucleic acid detection-this is an important link, and the organizer must pay attention to it.

This point, Xiao Bian should remind the organization unit of nucleic acid detection, because it is really important.

The organization of nucleic acid detection directly affects the detection quality and screening effect. Staff organization, testing resource allocation, testing object organization, and centralized sampling or sampling by building, unit and floor are all important factors.

For example, on November 26th, some districts and counties reported that "nucleic acid test samples were left behind", which may affect the accuracy and quality of nucleic acid screening for whatever reason, indicating the importance of organizational work.

At the same time, there are still many people who are concerned about the organizational level of nucleic acid testing institutions and the professional ethics of staff, which will also directly affect the testing quality and screening effect.

For the sake of everyone’s health and this city, please ask the organizers of nucleic acid testing to follow the process, make the work meticulous and put the management in place! Please!

Can nucleic acid be infected? Everyone should take personal protection, so don’t worry about it.

This point, Li Pan also made a detailed introduction. In fact, you don’t have to worry about doing nucleic acid testing and being infected.

Statistics show that more than 60% of the newly infected people are residents of the same building, the same neighborhood and the same community. The route of infection is often in community activities, with acquaintances and friends, shopping together, and taking express mail together (among them, infected people), without protection or standardized protection and contact.

However, there are very few cases of infection directly in the queue of nucleic acid collection or in the process of nucleic acid collection, but the results of flow adjustment are not supported, so don’t worry.

For high-risk areas, there are positive buildings and units that are tested at home, not to mention worrying.

Look, really don’t worry too much. As long as everyone takes personal protection and adheres to the "one meter distance", this situation can be put an end to.

Supervision of nucleic acid detection-never be soft when it comes to the end, and please continue to supervise the general public.

On November 24th, at the 148th press conference, Dan Yanzheng, deputy mayor of Chongqing Municipal Government, commander of the municipal epidemic prevention and control command department and director of the comprehensive office, said: At present, the results of nucleic acid testing in the whole city are authentic, so please rest assured.

He said-

Chongqing Municipal Party Committee and Municipal Government have always attached great importance to the quality of nucleic acid detection. In this round of epidemic, in view of the laboratory quality problems with a large amount of detection and public concern, on the basis of monthly laboratory quality assessment and quality control spot check in the early stage, the Municipal Health and Health Commission strengthened management supervision, with municipal quality control experts "conducting daily inspections" and district and county experts "guiding at the station", participating in laboratory management throughout the process, and promptly urging and rectifying problems such as irregular management and process of individual laboratories.

For violations of laws and regulations, we will maintain a high-pressure situation, and immediately start the investigation procedure according to law for the detection errors reflected by the public. Once found, hell to pay.

Ability of nucleic acid detection-Thanks to the strong support of brother provinces and cities, the ability of nucleic acid detection in Chongqing has been enhanced.

Everyone must have noticed that the staff and volunteers of nucleic acid detection are very hard: airtight protective clothing is worn for most of the day or even a day; alcohol cleaning gloves are constantly rubbed, cotton swabs are torn open and carefully sampled …

Especially in the face of this round of large-scale epidemic and large-scale nucleic acid detection, the whole nucleic acid detection system in our city is facing the pressure of long-term and full-load operation, and there are problems such as staff fatigue, high-speed operation of nucleic acid system and obvious lack of detection ability.

In this regard, under the guidance and support of Chongqing Working Group of the State Council Joint Prevention and Control Mechanism, Chongqing has received strong support from some brother provinces and cities, which has enhanced the strength of nucleic acid detection in our city.

What should we do-participate in nucleic acid testing as required!

Li Pan said that the majority of medical workers are fighting hard, hoping to eliminate the doubts of some citizens through continuous efforts and higher-quality nucleic acid testing.

What should we do personally to support nucleic acid testing? It’s simple—

Participate in nucleic acid testing as required! This is not only responsible for personal health, but also the need to prevent others from being infected.

At present, the incubation period of Covid-19 is usually 2-4 days, the shortest may be 1 day, or even less than 1 day, and the longest may be 8 days. Therefore, the management policy for close contacts is "5+3" (5 days of centralized isolation and 3 days of home observation) to minimize risks.

The high-risk area is managed by this scientific law, and it will be reduced to a low-risk area after 5 days without sunshine. But this does not mean that there is no risk, and we must continue to observe. If there is mobility, contact, activity and aggregation in the high-risk area, it will cause new infections. If there is a new positive test, the time will be recalculated.

Therefore, lifting the high-risk area does not mean unsealing, but also strengthening observation. In particular, the current epidemic situation in the central city is still severe and complicated, and it is still the coordinated prevention and control of the central city and the implementation of social control.

Here, Xiaobian asks everyone to understand, support and cooperate with various prevention and control measures as always, especially for nucleic acid testing-

Dear friends, don’t give up and refuse the nucleic acid you should do. Only by doing a thorough examination can you find the infected person as soon as possible, block the transmission chain, win a complete victory in the annihilation war as soon as possible, and return to the fireworks of this city as soon as possible.
