Since the American government announced its National Nanotechnology Plan (NNI) to the whole world in March 2000, nanotechnology, a little-known technical vocabulary in the 20th century, has become a high-frequency word when the media reported on scientific and technological plans and progress. Even some lawless elements use it to deceive some people who like "technology fashion".
　　
　　Nanotechnology refers to:
　　Nanotechnology will trigger a new industrial revolution in the 21st century. Undoubtedly, the birth and development of nanotechnology has opened up a new level of human understanding of the world, and extended human ability to transform nature directly to atoms and molecules, marking a new era of human science and technology. Scientists pointed out that nanotechnology will have a far-reaching impact on the development of productive forces, and it is possible to fundamentally solve a series of problems currently faced by mankind, such as extremely important problems such as environment, food and energy. Nanotechnology will be one of the leading technologies in the 21st century. The science and technology adviser of the President of the United States also spoke highly of the importance of nanotechnology to the future development of knowledge economy. He believes that the benefits brought by the development of nanotechnology to social development, economic revitalization and the improvement of people’s quality of life will be incomparable to general technology, and the wealth created by nanotechnology in the 21 ST century is also incalculable. The influence and penetration of nanotechnology in various fields may exceed that of computers. (Olympic Science and Technology Website)
　

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.

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!

(Related links: press conference, responding to concerns-Is nucleic acid testing true or not? Are you sure?)

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.

(Related links: do nucleic acid, remember "5321"!)

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.

(Related links: Medical teams from 8 provinces and cities in China rushed to Chongqing and successively entered Cuntan and Yuelai Fangcang Hospital to carry out medical treatment.)

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.

The fifth day of the fifth month of the lunar calendar is a traditional festival in China-Dragon Boat Festival. For more than 2,000 years, the Dragon Boat Festival has been a festival to commemorate the folk customs of all ethnic groups in China. From rowing dragon boats, eating zongzi and inserting calamus in ancient times to today’s national fitness, epidemic prevention, dispelling diseases, expelling heat and praying for health, many ancient customs have been completely passed down, and new good wishes have been added at the same time.

Every Dragon Boat Festival, the first thing that comes to our mind is to eat zongzi-sweet, salty, meaty and vegetarian. It can be said that every family has its own housekeeping skills, and every place has its own preferences.

The reason why Zongzi can be used as the representative food of the Dragon Boat Festival is to throw it into the river to prevent fish and shrimp from biting Qu Yuan’s body. Second, it is because the edges and corners of zongzi are like a knife, which can eradicate diseases and disasters.

Eating zongzi on Dragon Boat Festival not only carries the feelings of home and country, but also contains the deep feelings of family and friends getting together. Zongzi is known as one of the traditional foods with the deepest historical and cultural accumulation in China.

Do you know the origin of the Dragon Boat Festival?

When it comes to the origin of the Dragon Boat Festival, Qu Yuan is probably the first thing that comes to mind. According to legend, the king of Chu listened to slanderous rumors and exiled Qu Yuan. After Qin conquered the capital of Chu, the desperate Qu Yuan threw himself into the Miluo River with a big stone in his arms. After the death of Qu Yuan, the people of Chu were so sad that they flocked to the Miluo River to pay their respects to Qu Yuan, and there was a custom of dragon boat race and eating zongzi during the Dragon Boat Festival.

Do you know all the names of the Dragon Boat Festival?

The record of local customs in the Western Jin Dynasty contains "Midsummer Dragon Boat Festival". The end, the beginning. " This is the earliest origin of the word "Dragon Boat Festival".

There are many names for the Dragon Boat Festival, such as Duanyang, Yulan Festival, Dragon Boat Festival, Chongwu Festival, Dragon Festival, Zhengyang Festival, Tianzhong Festival and so on.

But what many people don’t know is that the Dragon Boat Festival also has the nickname "Daughter’s Day". In ancient times, from the first day of May to the fifth day of May, every family dressed up their girls and folded a pomegranate hairpin on their heads. This is considered as a ritual to avoid the "poison" in May and pray for the health of girls at home. Even if the daughter in the family grows up and marries, she will go back to her mother’s house to spend the holidays with her parents. Therefore, the Dragon Boat Festival is also called "Daughter’s Day".

How much do you know about the custom of Dragon Boat Festival?

Besides eating zongzi, there are many customs in the Dragon Boat Festival. How much do you know?

Chinese mugwort

grass

Legend has it that in ancient times, the gods had an agreement with the water monster, so long as people hung wormwood and calamus in front of their doors, the water monster should not be offended, so people liked to pick and hang wormwood on the Dragon Boat Festival, hoping to dispel demons and defend their families.

Wormwood itself has the functions of dispelling cold and removing dampness, warming meridians and stopping bleeding, and its stems and leaves contain volatile aromatic oil, which can repel mosquitoes and flies and purify the air. The smoke produced by the smoking of mugwort leaves can inhibit the spread of viruses and bacteria in the air.

boat

Qu Yuan threw himself into the river with hatred, and the people of Chu were reluctant to part with the death of his sage Qu Yuan, so many people rowed to catch up and save, which was the origin of the dragon boat race, and thus the dragon boat race became one of the most traditional customs of the Dragon Boat Festival.

Every year during the Dragon Boat Festival, the dragon boat race is an annual feast that can’t be missed. The "Hey Yo" sound of Qi Xin’s rowing inspires the players and the people watching the battle on the shore.

The ancients also wore sachets on the Dragon Boat Festival. In order to scent, repel insects and avoid plague, sachets were often filled with some traditional Chinese medicines with the function of "fragrant filth", such as clove, angelica dahurica, Pogostemon, perilla, mint, etc., which can refresh the mind, invigorate the spirit, dredge the nine orifices and prevent plague.

In ancient times, people were superstitious that the Dragon Boat Festival was the most unlucky and poisonous day of the year. Therefore, during the Dragon Boat Festival, every household should wear colorful ropes on their children’s wrists, that is, ropes made of five kinds of colored lines, namely red, yellow, blue, green and purple, to ward off evil spirits, drive away plague and turn good luck into good luck.

Every reporter Du Wei Wen Menghua every editor Dong Xingsheng

Looking for an overseas website to open a shop and sell China goods is attracting more and more businesses and capital.

According to enterprise survey data, in the first half of 2022, more than 20,000 cross-border e-commerce related enterprises were added nationwide. The Data Report of Cross-border E-commerce Market in China in 2022 (I) predicts that the cross-border e-commerce market is expected to reach 15.7 trillion yuan in 2022.

15.7 trillion, the market is very big, and the temptation is also great. "You don’t need to know English, the net profit of a single order exceeds 40%", "You can do it without purchasing channels and goods" and "The guaranteed turnover is 40,000 yuan a month". It is these tempting marketing terms of "cross-border e-commerce" that make dozens of people from all over the country, such as Li Yun from Guizhou, Zhong Yong from Hebei and Yu Wei from Inner Mongolia, fall into the trap of new tricks in just a few days, and some families even fall into it.

What is even more embarrassing is that these businesses don’t even know who they have been cheated by.

"This is a new situation." Li Chengdong, the founder of e-commerce of Dolphin Think Tank, pointed out in an interview with national business daily. Chen Zixing, a lawyer of Beijing Anbo (Chengdu) Law Firm, also told reporters that it was the first time that the seller suffered a "chain scam" case. "The cross-border e-commerce store and the website where the goods were purchased in the case were all fake."

Taking advantage of the information gap at home and abroad, the new deception that lures merchants to enter has cast a shadow over the rising cross-border e-commerce. After more than two months of follow-up investigation, the reporter personally experienced how Li Yun and others were tempted to open stores step by step, trying to break through the tightly woven network of chain scams; And talk to industry authorities, lawyers, etc., restore the reasons behind the new scam, and explore the problems and opportunities of cross-border e-commerce industry.

One ring and one ring: nearly 750,000 yuan was cheated in half a month.

In October 2022, Li Yun, who opened a physical clothing store, was attracted by the "gimmicks" such as cross-border e-commerce to open stores for free and without supply, thinking that he had encountered a "precious" entrepreneurial opportunity. Unexpectedly, she fell into a huge trap.

Under the guidance of the online "teacher", Li Yun opened a shop in Lelong shop that day, and purchased it through "Youhuo.com" and sent it to overseas buyers. Initially, Li Yun quickly received the payment on Lelong shop.

"I checked Lelong, which was established in 1998 and is very famous abroad." According to Liu Yun, in the next few days, more and more orders were placed, and the amount was getting bigger and bigger. "I have more than 100,000 yuan in each order."

Not without doubt. When she invested 4000 yuan, Li Yun called the relevant authorities, but at that time it was not clear whether it was fraud, so she didn’t care. After that, Li Yun opened two more stores in the name of his parents.

From the initial free shop opening, to the payment of several hundred yuan, and then to tens of thousands and hundreds of thousands of yuan, as the order is getting bigger and bigger, like "snowballing", in order to get the payment back, Li Yun has also spent more and more money. In order not to let the previous money go to waste, she can only continue to invest more money. After being unable to pay for the purchase of new orders, all three stores of Li Yun were frozen by the website. The "teacher" told her that she needed to pay a deposit of $50,000 to unblock the store. Until then, Li Yuncai realized that he had fallen into a scam and called the police.

The reporter logged into the backstage of Li Yun’s frozen women’s clothing store and saw that at present, Li Yun’s pending settlement amount exceeds 60,000 US dollars, and the settled amount exceeds 30,000 US dollars (the settlement failed to be withdrawn after the store was closed). "I have already delivered the unsettled and settled goods. I invested more than 600,000 yuan in this store alone." Liu Yun said that in just 15 days, his three stores were frozen successively, and more than 700,000 yuan was invested in Shui Piao. Among them, on the day of the alarm on October 24, 2022, I hit another 100,000 yuan.

For Liu Yun, this more than 700,000 yuan not only spent his savings, but also caught up with his parents’ savings for half a lifetime. What happened to Liu Yun is not a case. The reporter found that more than 30 sellers from all over the country had the same experience on the platform of "Lelong shop" alone. As of January 6, 2023, according to the reporter’s rough statistics, they have been cheated by more than 2 million yuan.

Yu Wei, who lives in Inner Mongolia, told reporters that she found that it was not the same collection account on the third day when she opened the store. She felt that it was not right, but after being induced by the "teacher" to check the backstage payment, she made another 8,000 yuan. "There were 50 orders of about 20,000 yuan that night. I asked the customer service to inform the customer to return the goods on the platform, but there was no response; Negotiating with the’ teacher’, the other party also said that there is no way to close the store and freeze the account if it is not delivered on time. "

Experience the deception of no supply: set big money with small money

"Open a shop without supply" and "Free of any deposit, tuition and consulting fees", and open the advertising links provided by the above sellers. The reporter saw that the advertising language on the poster was very attractive.

After the reporter clicked "consult now", he added the WeChat of "Customer Service of SiteGiant Co., Ltd." through a QR code. According to the other party, Lelong is the largest e-commerce platform in Malaysia, and now it is fully inviting investment from China merchants, with limited places.

When the reporter checked the enterprise information of SiteGiant Co., Ltd., he found that the number was "filled in by individuals" and no relevant information was submitted to verify the authenticity of the main information.

"There is no charge for supporting you to open a shop." The other party repeatedly stressed to reporters. Subsequently, it guided reporters to download ICQ software, and then pulled the group to introduce the operation of "teachers" to guide the opening of stores and selling goods. The reporter’s experience is exactly the same as that of Yang Liang, who works in Germany.

Yang Liang introduced that the "teacher" helped him with how to classify the product map and how to design the logo. At first, the other party was particularly enthusiastic. "Every day, I will help me pay attention to the store dynamics, teach me by hand, and ask me questions." When the store was placed by an overseas buyer, the teacher taught him to go to Youhuo.com to search for the goods the buyer wanted, and then he called the private account provided by Youhuo.com, "Tell me that I don’t pay taxes for my personal business, and I will believe it".

When "Youhuowang" delivers the goods for him, he can fill in the order number back to Lelong shop, which is regarded as the completion of the order. "They said that when the buyer receives the goods, I can go to the store to withdraw money." Yang Liang said, according to the "teacher", "every order will have a net profit of at least 40%. However, the delivery must be completed within 24 hours of the buyer’s order, otherwise it will be regarded as a violation and the store will be frozen. "

Everything went smoothly at first, but with the increasing amount of orders, Yang Liang’s investment in payment became more and more difficult, and the funds began to turn around. He once told the "teacher" not to push the flow and not to take orders first, but the orders were still one after another.

In just one week, Yang Liang’s shop was closed twice for failing to deliver the goods on time. After he scraped together a deposit of $1,000, the "teacher" also blamed him: "Don’t you even have one or two bosom friends?"

Yang Liang tried to contact overseas buyers and negotiate to cancel the order, but found that the other party was empty. When he questioned the "teacher" and asked questions, "The customer has placed an order of 100,000 yuan, and I have no money to purchase it. Can’t I not do this order?" However, it was accused by the "teacher" as an "unscrupulous merchant". "How can you make a phone call without an area code? How much money you prepare, just say in advance, you don’t say … you can’t solve it in violation of the regulations, just say that you have been cheated. "

At this point, Yang Liang just woke up, he is met "kill pig plate". Therefore, I immediately entrusted my domestic friends to call the police.

The public security bureau ran back and forth several times, but I still don’t know who cheated.

Is the Lelong shop where more than 30 sellers have settled in Malaysia?

The reporter called Lelong many times, but as of press time, he did not get a reply. "Lelong is a relatively old e-commerce platform in our country." Su Yanlu, Acting President of China Silk Road Entrepreneurs Association, told reporters that although the company address displayed on the website page of Lelong shop is the same as Lelong’s, there is no registration number required by the local government, and the logo of the two websites are different.

"I cried and begged my mother to trust me and lend me money to do cross-border e-commerce. As a result, I was cheated by nearly 750,000 yuan." After running back and forth several times in the Public Security Bureau, Liu Yun still doesn’t even know who he was cheated by. Another seller, Luo Qian, also smiled bitterly at the reporter: "When I went to the police station to report the case, I was asked the name of the fraudster or company."

No one knows the company information behind Lelong shop, and dozens of sellers also make personal calls to Youhuo. com, and the account number is different every time.

During the interview, almost all sellers mentioned to reporters that online stores sometimes can’t be opened, so they can only contact the "teacher" and use the re-sent website to enter. In this regard, the reporter asked the IT staff, and analyzed the Lelong shop and Youhuo.com mentioned by the seller by technical means, and found that the IP addresses of these two websites would "move" from time to time, but only in Tokyo and Hong Kong, China. "From the analysis results, the high probability is that the same company is operating, and the production price of such websites is low, and one can be made for several hundred yuan."

"The’ teacher’ said that our website is a sub-website of Lelong, which is aimed at China sellers and the company is in Hongkong." The seller, Li Lu, provided several videos to the reporter. After the store was frozen, she found a friend in Hong Kong and asked him to help to ask about the situation at the scene. According to the video recorded by his friend, there is no company related to Lelong shop in the office building where the address is located.

As a result, when the above-mentioned dozens of sellers realized that they were "cheated", they suddenly found out that no one even knew the "complaint" when they consulted a lawyer or reported the case to the police.

An e-commerce industry veteran told reporters that these dozens of sellers may encounter "chain scams", not only overseas stores are fake, but even the purchase website is fake, and there is no so-called overseas buyer at all.

According to the addresses and telephone numbers of overseas buyers provided by several sellers, the reporter called buyers in new york, London and other places for verification, but none of them could be connected, most of which were empty or wrong.

Wearing a cross-border e-commerce coat, online fraud

Before the "reverse Haitao" became popular, many China merchants had been "panning for gold" on platforms such as Amazon and Shrimp Skin. Compared with the capital investment and process of opening stores on these large platforms, criminals are aiming at the psychology that businesses want to try simply.

"This incident is a cross-border e-commerce cloak and online fraud." A veteran of the cross-border e-commerce industry analyzed that Lelong shop and websites with goods are located overseas or are fraudulent, which may make it difficult to implement supervision in China.

"Using overseas servers and virtual IP addresses to carry out illegal activities is a relatively high incidence in recent years, which undoubtedly increases the difficulty and cost of victims’ rights protection, and also increases obstacles and challenges for police investigation." Chen Zixing, a lawyer of Beijing Anbo (Chengdu) Law Firm, said in an interview that although he had been exposed to many cross-border e-commerce disputes, he encountered a case of "chain scam" for the first time.

Chen Zixing believes: "The incident has been suspected of a criminal offence, but it is difficult for the deceived seller to find out and confirm the subject identity and contact address of Lenglong shop by personal strength."

The reporter learned that in desperation, most sellers have used the search platform when searching for "cross-border e-commerce" as the defendant’s main body to report the case to the police.

"If the search platform pushes the relevant links and platforms of lenglong shop as advertisements, it may be recognized as an advertisement publisher. According to the relevant provisions of the Advertising Law, if false advertisements are published to deceive and mislead consumers and damage the legitimate rights and interests of consumers who purchase goods or receive services, advertisers shall bear civil liability according to law. " At the same time, Chen Zixing stressed that if an advertising agent or publisher cannot provide the real name, address and effective contact information of the advertiser, consumers can ask the advertising agent or publisher to pay compensation in advance.

In Chen Zixing’s view, the main problems faced by cross-border e-commerce victims in taking civil judicial channels are: First, it is difficult to determine the identity information of the defendant; Second, it is difficult to deliver judicial documents, and most cross-border e-commerce perpetrators are not in China; Third, it is difficult to implement and collect money. Even if the judgment is successful, there may be no property available for execution.

According to Chen Zixing, there are two main ways to relieve victims’ rights. First, the seller provides the information of the co-payee to the police and reports the case, and the police investigate and recover the money; The second is to take the payee as the defendant and bring a civil lawsuit to the court with jurisdiction to demand the payee to return the money.

Reporter’s Note: The space for cross-border e-commerce to create wealth is far beyond imagination, but it also has many traps.

As a factory in the world, cross-border sellers in China are the targets of major e-commerce platforms.

Relevant data show that in the past five years, the scale of cross-border e-commerce in China has increased nearly 10 times. In 2021, the import and export scale of cross-border e-commerce in China reached 1.92 trillion yuan. The report "Digital Platform Helps SMEs Participate in Global Supply Chain Competition" predicts that by 2025, the B2B market of cross-border e-commerce in China will reach 13.9 trillion yuan.

"As a new Nugget track, cross-border e-commerce has far more room for wealth creation and development than we imagined, but what we see is often only the winners. After people outside the industry actively or passively heard these success stories, they began to understand cross-border e-commerce, but they did not form a complete cognitive system and discrimination ability for cross-border e-commerce." Yao Zhengyi, secretary general of Chengdu cross-border electronic commerce Association, said in an interview.

"When the cross-border sea became a big market, it was also targeted by scammers." Li Chengdong, the founder of Dolphin Think Tank E-commerce, pointed out to the reporter that "doing cross-border e-commerce needs special caution. Sellers are lucky enough to believe that nothing needs to be invested, as long as they open a store, they can make money. "

The reporter learned through a large number of interviews that among dozens of deceived sellers, some people were attracted by gimmicks such as the operation of the marketing number of the "cross-border e-commerce" course on the short video platform. However, after entering, I encountered a fancy scam, and all the shops I opened ended in being frozen.

The seller Liu Li brushed a short video of cross-border e-commerce and came up with the idea of opening a store. After investing tens of thousands of yuan, the particles were not collected; Tian Honghua in Beijing paid nearly 30,000 yuan to find someone to operate on his behalf, and the other party ignored the "freezing" of his store after receiving the money …

There are no quick channels and rules for making money in any industry. Yao Zhengyi suggested that businesses that want to set foot in the cross-border e-commerce industry need to learn through formal channels to avoid falling into traps such as zero supply and fake shops.

As a consumer, the reporter learned from a number of cross-border e-commerce agency companies in the market that the "cooperation package" ranged from several thousand yuan to nearly 50,000 yuan, and promised tens of thousands of dollars a month to the agency stores.

"Last year, many colleagues disappeared." Xiao Le, who has been doing cross-border e-commerce operations for nearly three years, told reporters that the situation is very good, but the market is chaotic. "Those who are irresponsible and play routines will lose trust, and few can persist."

"China enterprises now need to go global. However, the real industry and brand going out to sea require enterprises to establish their own core teams, constantly explore and link resources from all parties to form a complete industry knowledge system. " Yao Zhengyi appealed that in order to make the cross-border e-commerce industry develop more orderly and efficiently, lawyers, scholars and other professionals who have studied the cross-border e-commerce industry can discuss the formation of some rules and mechanisms to avoid new online fraud incidents under the guise of cross-border e-commerce.

　　editorial comment/note

　　Promoting the creative transformation and innovative development of Chinese excellent traditional culture, better constructing China spirit, China value and Chinese strength, and providing spiritual guidance for the people are the requirements put forward in the report of the 19th National Congress for the whole party to deeply understand and implement the spiritual essence and rich connotation of Socialism with Chinese characteristics Thought in the new era. As for TV variety shows, in recent years, under the policy control of the State Administration of Press, Publication, Radio, Film and Television with the development direction of "commonweal, culture and originality", the number of entertainment programs with copyright such as singing and talent shows has been greatly reduced, and the proportion of cultural independent original programs with China characteristics has been increasing day by day. It has become a common practice to promote the transformation and development of excellent traditional culture in the form of images, which has made a useful demonstration in the cultural field.

　　In the spring of 2017, the second season of the Chinese Poetry Conference, the Reader and other cultural programs were launched one after another, and the screens were popular, which not only attracted high ratings and attention, but also won rave reviews from the audience. Many industry experts came to the conclusion that "the spring of cultural programs has arrived". As a result, major TV stations and producers have boarded the development express train "bound for spring" and launched works such as I am an orator, Chinese characters, traveling thousands of miles, Chinese restaurant and Chinese series. At the same time, the popularity of cultural programs is also rising. The first stage of the network variety "The Speaker" has a total broadcast volume of 590 million; Hunan Satellite TV’s "Chinese Restaurant" has been the number one viewing champion for 11 consecutive issues, and the cumulative network broadcast volume has exceeded 2.6 billion; The first program of "Cheer for China" by Oriental TV reached an average audience rating of 0.74% in 35 cities nationwide, with 128 million TV viewers, setting a national audience rating record for traditional Chinese opera and cultural programs in the past three years … … To explore the reasons for the recent popularity of cultural programs and the ratings of Qi Fei, the main reason lies in the creators’ continuous transformation and upgrading to adapt to the changes in the market environment on the basis of cultivating the fertile soil of traditional cultural resources, so that the quality of works is steadily improved, and generate is full of vitality.

　　Creative innovation "deeply cultivates and broadens" traditional culture

　　For a long time in the past, the phenomenon of serious homogenization of cultural programs in China has been criticized by the industry. After the quiz show "Lucky 52" and "Happy Dictionary" became popular on the screen, a number of works with similar forms swarmed in. When "Lecture Room" was a smash hit, similar "lecture" programs rushed to the beach market … … The cluster broadcast of the same type of programs not only makes the audience feel aesthetic fatigue, but also makes the creation fall into a narrow lane of thinking. Happily, this problem has been significantly improved in the past two years. Cultural programs have achieved breakthroughs in the expansion of theme styles, the excavation of cultural connotations and the innovation of production concepts, and gradually entered the 2.0 era.

　　China’s traditional culture not only contains many outstanding core ideas and concepts, such as caring, honesty and justice, but also contains rich and complex ancient myths, classic ancient books and literary works. These classic cultural treasures, which often appear in textbooks and books, are like spring snow, giving people a feeling of "high cold", which inevitably makes TV audiences who mainly appeal to entertainment, release pressure and enrich their spare time feel dull and obscure. In order to make the program grounded and popular, the creators try to use all kinds of trendy and fashionable expressions and image languages that young people can understand. For example, The Book of Poetry by Oriental TV breaks through the inherent competition form of general educational culture programs, takes "Poetry into the homes of ordinary people" as the core idea, and pays attention to the flexible use of poetry in life; Anhui tv’s folk song competition program "China in My Ear" not only reproduces the classic melody of traditional folk songs to awaken the national memory infiltrated in the blood of Chinese people, but also innovatively incorporates modern elements, presenting popular style "Under the Silver Moonlight" and rock singing "I Love You, Snow in the North of Saibei" to show the enterprising spirit of young singers.

　　From learning Chinese characters together, reciting poems, busy dictation and holding competitions, to promoting reading, paying attention to folk songs, focusing on food and propagating family style, cultural programs have also jumped out of the old pattern that it is difficult to have new ideas, and are no longer confined to the competitions of poems and songs, but have opened up many humanistic themes focusing on urban scenery, food, opera and other fields. "Charming China City" by CCTV Financial Channel turned its creative vision to urban culture, and adopted a two-pronged model of "culture+tourism" to dig deep into the rich connotation and unique charm of the city. The Chinese Restaurant, which was recently broadcasted on Hunan Satellite TV, takes the story of Chinese opening a Chinese restaurant in a foreign country as the framework, which runs through the clues of spreading Chinese food culture and shows the confidence and tolerance of China’s traditional food culture.

　　Sincere feelings make the program "high but not cold"

　　High-value programs should not only temporarily attract the audience’s attention with novel forms, but also make them watch, think positively and discuss enthusiastically, infect and inspire people and guide the way forward. Therefore, while thinking about how to improve the expression form of the program, producers try to realize the transmission of "internal" value through this "external" change. Dong Qing, the producer of The Reader, said: "We construct the reader’s personal life experience through conversation. When the speaker and the listener have the same mind and the emotion reaches a certain saturation, the text comes out with the trend. The guests were restored to the appearance of sincere readers on the stage, at ‘ I want to read ’ Not ‘ I can read ’ In the active expression of, complete ‘ Asking about life in the name of literature ’ The mission. "

　　In the case that the trend of variety show "fighting for star lineup" has been widely criticized by the industry, many creators of cultural programs do the opposite, emphasizing "civilian consciousness" and paying attention to the interaction between their works and people from all walks of life. As a result, more and more topics are concerned about the fate and feelings of ordinary people and reflect the great practice of people’s production and life, making cultural programs more zeitgeist and practical significance. For example, Hunan Satellite TV’s "A Thousand Miles of Children" uses documentary shooting, interviews with people and other methods to visually and vividly present the family letters and the ordinary stories between parents and children behind them, showing the good family style of ordinary people. In "I am an orator" by Beijing Satellite TV, ordinary people from different educational backgrounds, different regions and different industries tell their life experiences in front of the audience: the courier still does not give up his dream after hard work, the soldier excitedly tells his mission, the Harvard girl tells us with personal experience that "the country is strong and the teenager is strong", and the network anchor is named "Shoumai" … … The presentation of these "amateurs" diverse attitudes towards life can not only help different audiences to find the content that is in line with their own ideas, thus generating emotional resonance, but also demonstrate the upward attitude towards life and deep feelings of home and country in contemporary Chinese.

　　A variety of paths make excellent culture "spread properly"

　　Internet instant messaging, two-way interaction, mass storage and other characteristics bring not only the optimization and upgrading of content production and the change of audience interaction mode, but also the expansion of communication pattern, the increase of communication channels and the change of communication mode to TV programs. In this case of drastic changes in the communication ecology, producers should keep pace with the times and actively adjust their propaganda ideas in order to obtain a wider audience and a stronger audience stickiness, and realize the geometric expansion of the influence and communication power of cultural programs through "two micro-ends" propaganda matrix, network synchronous live broadcast and other ways.

　　Zhejiang Satellite TV’s "Chinese Characters" has produced several short video programs "Test Your Word", and each video has tens of millions of clicks and forwards; "Cheering China" pushed the talent performance of "cheering people" to major social platforms in the form of video, which quickly attracted the attention of netizens. Many producers have grasped the characteristics of fragmentation, mobility, event and socialization of new media, and spread program information such as stories, quotations and cartoon images of participating guests to online communities, amplifying their news value and forming a "cultural phenomenon".

　　In the era of media convergence, cultural programs should also learn to integrate the resources of big screen and small screen, open up the two lines of online and offline, and build a communication framework of all-media interaction. "The Speaker" pioneered the platform mobile live broadcast. The bus of the program group was broadcast live in five cities across the country. Players can wave to get on the bus at any time, and the winners stay and the losers get off, which greatly improved the public participation. "Cheer for China" cooperated with the "Everyday P Picture" APP to launch the "Drama Face Changing" activity, which received 2.4 million reposts in four days. These innovative methods not only make the existing cultural programs go to the public, but also incite the market demand for more high-quality programs with cultural nourishment and value resonance functions, and realize the creative transformation and innovative development of Chinese excellent traditional culture.

　　Beijing, April 11 (Xinhua) Recently, a news about "super fungi" triggered a heated discussion in society. The Beijing Municipal Center for Disease Control and Prevention announced today that the "super fungus" is Candida auricula, which can cause serious infection in hospitalized cases. Healthy people are usually not infected with Candida auricula, which poses a low health threat to the general public.

　　Beijing CDC pointed out that the so-called "super fungus", named Candida auris, is a fungus that can cause serious infection in hospitalized cases. The data show that Candida auricula was discovered only in recent years and was first discovered in Japan in 2009. Through the retrospective detection of stored candida, it first appeared in South Korea in 1996.

　　According to statistics: At present, there are reports of cases of Candida auricula infection on all continents. As of February 28, 2019, there were 587 confirmed cases in the United States. There have been a few cases reported in China.

　　According to the Beijing CDC, because healthy people are usually not infected with Candida auricula, Candida auricula poses a low health threat to the general public, and the public need not panic or take special preventive measures.

　　Who is susceptible to Candida auricula infection? What are the main hazards?

　　Candida auricula can not only cause symptomatic infection, but also be carried in the body without symptoms. Candida auricula infection mainly involves hospitalized cases, and the high-risk population is patients with severe chronic basic diseases or immunosuppression (such as diabetes, chronic kidney disease, HIV infection, tumor, etc.); Newborns, patients with intubation or indwelling catheter, surgical patients and patients who use broad-spectrum antibiotics or antifungal drugs can also be infected. Healthy people usually don’t get candida auricula. The symptoms caused by Candida auricula depend on the location of infection, including bloodstream infection, wound infection and ear infection. Among them, bloodstream infection is the most serious, and the mortality rate can reach 30-40%.

　　What are the main treatments for this fungus at present?

　　At present, the fungus is mainly resistant to fluconazole, but the resistance to other antifungal drugs varies among different strains. At present, there are strains resistant to three main antifungal drugs. Most cases of Candida auricula infection can be treated with echinocandin antifungal agents, and cases of multi-drug resistant Candida auricula infection can be treated with high-dose and multi-antifungal agents.

　　Guangming net news Since the beginning of this year, large language models such as ChatGPT and ERNIE Bot have been popular, and the question of whether artificial intelligence (AI) can surpass human beings has aroused heated discussion. On May 29th, the "2023 China Computing Power Development Seminar" organized by China Intelligent Computing Industry Alliance was held in the Institute of Computing Technology, Chinese Academy of Sciences. The theme of this seminar is the opportunities and challenges of computing power under ChatGPT, which brings together many authoritative experts and scholars in the industry to conduct in-depth exchanges and discussions from multiple dimensions such as technology and ecology, determine the development trend of the liquidation power industry, and give countermeasures for the current artificial intelligence infrastructure and computing power service construction.

　　At the seminar, Chen Runsheng, an academician of China Academy of Sciences, said that the development of artificial intelligence is unstoppable by human beings, which is the essence of scientific development. At the same time, he pointed out that the phenomena of "Breakthrough" and "Grokking" in the big language model deserve our consideration.

　　What is "emergence"? A complex system is made up of many tiny individuals, who come together and interact with each other. When the number is large enough, it shows a special phenomenon that can’t be explained by micro-individuals, which is called "emergence". Chen Runsheng vividly explained, "I gave it (the big model) a lot of learning data, and as a result, there will be something in its answer that is not in the learning data. This phenomenon is called emergence." The calculation of a large model shows that when the training data is large (for example, more than 100 billion), there will be an emergence phenomenon, and this phenomenon will not occur when the scale is small.

　　What needs to be clear is that the emerging phenomenon is controversial in the scientific community at present. For example, a professor at Stanford University thinks this is a metric problem, which involves measurement, basic physical coordinate system and so on.

　　"Emergence in the process of natural language processing due to the rapid increase of the whole computation is a new problem, which is worth considering," Chen Runsheng said.

　　What is an epiphany? Chen Runsheng explained, "In the process of training a neural network, you don’t understand it once, twice, the fourth time, and the fifth time. Just like a child learning something, you don’t understand it once or twice, and you suddenly learn it after teaching N+1 times."

　　He believes that this is a model of human brain learning, "learning to understand at a certain time", "computers can’t have epiphany, but large models will have epiphany."

　　Not long ago, Claude, one of ChatGPT’s main competitors, expanded the number of tokens in the context window to 100,000, equivalent to 75,000 words, which greatly exceeded the 8192 tokens in the context window of GPT-4. This means that users can upload up to 500 pages of documents to Claude, which can understand and digest the information in less than 1 minute and answer users’ questions based on the uploaded information.

　　Claude was launched by Anthropic, a company founded by former OpenAI employees. Since the end of 2022, Google has invested nearly $400 million in the company.

　　In this regard, Chen Runsheng believes that the current learning speed of large models is much faster than we thought. "These two companies (OpenAI and Anthropic) are catching up with each other. Maybe after a while, GPT-5 will be stronger than Claude, and it will develop so fast that people will not catch up in the future."

　　"What’s more troublesome is that these big model companies are considering manipulating third-party equipment," Chen Runsheng said. "Being able to manipulate third-party equipment is a worrying thing. If you manipulate things related to safety and national defense, it will be terrible."

　　Chen Runsheng admits that the structure of human neural network is much more complicated than the current big model, and the development of artificial intelligence still has a long way to go. "The current (artificial intelligence) neural network should have revolutionary changes in the spatial structure model. Maybe at that time, (AI) can really surpass human intelligence."
