China News Service, Jinhua, February 14th (Qian Chenfei)
Xu Zhengda) From February 9 to 14, more than 40 teachers and students from many universities in Taiwan Province walked into Hangzhou and Jinhua, Zhejiang, to carry out in-depth cultural and artistic exchanges. In the meantime, Taiwan Province teachers and students watched the animated film "Nezha’s Devil Children Making a Sea" together.

　　"The first time I saw the Nezha series, it was wonderful and worth watching." After the movie, Wei Meijuan, a student from Taiwan Province, couldn’t calm down for a long time. In her view, the image of Nezha in the movie is very three-dimensional, and many people can’t do it, which also makes the movie more exciting.

　　Liu Jiazhen, a student from Taiwan Province, also spoke highly of the film. It said, "The Devil’s Boy in Nezha is a classic story from a new perspective. The film is exquisite and the battle scene is shocking, which makes people stare."

　　In Liu Jiazhen’s view, the film integrates the themes of affection, friendship and growth, and shows Nezha’s inner struggle and self-redemption. The emotional depiction is profound and moving, the role design is unique, and the special effects and music complement each other, bringing excellent viewing experience. "On the whole, this is a masterpiece of the country that combines blood, humor and depth. It can not only cause thinking, but also make people excited. It is worth seeing. I hope that more outstanding mainland film and television works can be released in Taiwan Province. "

　　It is understood that more than 40 teachers and students from Taiwan Province come from more than 10 local universities. During their stay in Zhejiang, the movie "Nezha’s Magic Children Making a Sea" was shown, and the box office of the film has exceeded 10 billion yuan.

　　"Cross-strait cultures are of the same origin, and themes such as Nezha and Feng Shen are part of Chinese culture, so young people in Taiwan Province are no strangers to this." A Taiwan Province teacher said. (End)

Yesterday, it broke the news that Liu Yifei’s mother and Chen Jinfei started a new company in partnership, and Liu Yifei’s mother Liu Xiaoli invested 1.8 million yuan and held 60% of the shares; Chen Jinfei contributed 1.2 million yuan, holding 40% of the shares. This is the first public cooperation between the two people since 2019, which has aroused heated discussion among netizens.

Some netizens said, it is no wonder that "Americans are coming back to make movies again, so it was michel platini who came back". Externally, Liu Yifei once claimed that Chen Jinfei was his "godfather", which is more like what we usually call "adoptive father", that is to say, Chen Jinfei and Liu Yifei are father and daughter.

Speaking of the process of getting to know each other, Hu Jun has heard many versions. Some people say that, in fact, the relationship between Chen Jinfei and Liu Yifei’s mother is confusing. It is reported that Chen Jinfei and Liu Yifei’s father’s family are family friends, so Liu Yifei is recognized as their adopted daughter. Others think that her mother Liu Xiaoli and Chen Jinfei are lovers according to the "stepfather" statement mentioned by Liu Yifei in the interview. However, to the outside world, this rich man has always claimed that he is Liu Yifei’s agent, and there are quite a few pictures of three people in the same box.

　　　　"Beijing is not a sandstorm, it is a saline-alkali dust storm! Accordingly, sand control should be changed to dust control. " Zheng Baiyu, Secretary General of the Ecological Poverty Alleviation Committee of yenching university Beijing Alumni Association, reported this unique view at the third Sino-Korean seminar on desertification control and grassland protection in 2006.

　　　　Zheng Baiyu has lived in Xilin Gol grassland for many years. After retiring in 1999, he continued to engage in ecological and environmental protection activities in grassland, especially in recent years, he has carried out many years of scientific research and control practice on the harm of saline-alkali dust storms caused by the drying up of Chagannuoer Lake, and has his own unique views on the dust storms.

　　　　The dry Lake Chagannor is the source of dust storms.

　　　　Zheng Baiyu told the Science Times reporter that Chagannuoer Lake with an area of 110 square kilometers is located at the junction of the northern edge of Hunshandake Sandy Land and Xilin Gol Grassland, roughly 600 kilometers north of Beijing. Gogestai River, the source river of Chagannuoer, originates from Hunshandake Sandy Land. In the past two or three decades, the weather has become hotter and drier, and the Gogsitai River has become less and less, and it is often cut off, resulting in the Chagannuoer Salt Lake drying up in the spring of 2002.

　　　　"Since the summer of 2002, I have invited Han Tonglin, a researcher at the Chinese Academy of Geological Sciences, Song Huailong, a researcher at the Institute of Oceanography of the Chinese Academy of Sciences, and other experts, scholars and environmental protection volunteers to conduct on-the-spot investigations and investigations, and found that the dust storm caused by the dry Lake Chagannor is different from the sandstorm we generally know, and the dust it carries contains a lot of saline-alkali substances."

　　　　Zheng Baiyu said that the sight seen in Chagannuoer Lake is shocking: the dry lake basin is full of white saline-alkali dust, which is very fine and loose, and you can raise smoke when you step on it. Salinity will even crystallize in wet places and become saline-alkali ice flowers. Loose saline-alkali dust will be raised when the wind is not very strong. Generally, when the wind is 5 ~ 6, almost pure saline-alkali dust rises locally in the lake basin, and a white saline-alkali smoke covers the lake basin area. Sometimes the saline-alkali dust is rolled into a column of smoke like a tornado and rises very high. When the wind increases to 7 ~ 8, even the dust rolls up and becomes a strong mixed dust storm of saline-alkali dust.

　　　　The sandstorm often mentioned is actually a saline-alkali dust storm.

　　　　"From the situation of Chagan Noel, the sandstorm we are talking about now should be a dust storm in essence, and it is a dust storm rich in saline-alkali substances. The dust of the saline-alkali dust storm is very slight, rising very high, and will enter the atmospheric circulation and be transported to far places. From the path of dust storm, it affects Beijing, Tianjin and North China. Without intervention, the Chagannuoer dry lake basin will also evolve into a desert or sand. "

　　　　Zheng Baiyu pointed out that the research conclusion of Chagannuoer and the understanding of saline-alkali dust storm are quite different from the traditional sandstorm theory in China. The traditional sandstorm theory focuses on the physical parameters such as power source, material source, path, harm, prevention and control, and there are two big indexes that are not involved or not well expressed-the relationship between the particle size of sandstorm inclusions and sandstorm movement, and the chemical composition of sandstorm inclusions and its influence.

　　　　Han Tonglin believes that it is of great significance to determine the particle size of dust entrained by sandstorms. In layman’s terms, it is necessary to determine whether the components of sandstorms affecting eastern China are mainly "sand" or "dust", and to determine the birthplace. "If it is sand, the focus of work is on controlling sand sources; If it is dust, treat the dust source. "

　　　　According to Han Tonglin, the granularity of sand and dust is different. Under the same wind, the finer the particles, the higher they rise and the farther they are transported. "According to the classification method in China, the classification standard of soil mechanical composition is 8 grades, namely gravel, extremely coarse sand, coarse sand, medium sand, fine sand, extremely fine sand, silt and clay. When the wind speed is 15m/s (level 7), the floating distance of 0.1mm fine sand is 4.5 ~ 45m, and the floating height is less than 8m. The floating distance of 0.01mm silt is 45 ~ 450 kilometers, and the floating height is below 800 meters. In the sampling of eight deserts in China, fine sand accounts for 85.6%, medium sand accounts for 11.6%, and the rest is coarse sand. It is unfounded to think that desert is the material source of sandstorms. "

　　　　In addition, the sand in the desert and the dust in the sandstorm are not only a matter of particle size, but also have different movement forms, settlement locations and prevention methods.

　　　　Han Tonglin said: "If we distinguish the size of dust particles in sandstorms, we can find that the current measures to prevent and control sandstorms are inappropriate-for curbing dust storms and controlling dust storm sources, the role of afforestation is limited. It can neither stop dust storms in Beijing, Tianjin and North China, nor is it the best means to restore the ecology of dust source areas, especially in the desert areas that have been formed. It is a waste of national financial resources."

　　　　Song Huailong believes that the current standards and definitions cannot fully reflect other attributes of sandstorms. "Generally speaking, it is not clear what the chemical composition of sand and dust substances is and the impact of these components on people’s lives, social activities and ecological environment. According to the source, movement and environmental impact on human beings and ecology, dust storms can be divided into physical dust storms and chemical dust storms. The toxicological effect of chemical dust storms is a part worthy of special attention. "

　　　　The chemical dust storm has been verified by experiments.

　　　　For the viewpoint that sandstorms in China are chemical dust storms, several researchers provided experimental data.

　　　　A research team of Beijing Normal University made a laboratory analysis on the components of the extraordinarily serious sandstorm in Beijing on March 20th, 2002, and wrote a paper entitled "Saline soil source of dry salt lake of sandstorm in Beijing", saying that "the surface soil of the arid and semi-arid areas where sandstorm passed through including dry salt lake and saline soil is also its main source".

　　　　The Institute of Geology, Chinese Academy of Geological Sciences, analyzed the dry dustfall in Beijing on April 16 this year, and the results were almost the same as those of the research group of Beijing Normal University. According to the results of electron microscope scanning and chemical analysis of water-soluble salts at room temperature, the dust storm in Beijing on April 16 was a chemical dust storm. The results of particle size and content measurement by scanning electron microscope show that 96% of the particles are smaller than 0.074mm, and 4% are smaller than 0.154mm and larger than 0.074 mm. The pH value of dust is 7.9, which is alkaline. The structure, geochemical characteristics and the detection results of water-soluble salt at room temperature show that the composition of dust is basically the same as that of soil samples in dry saline lake basin, but different from that in Hunshandake sandy land and degraded grassland, indicating that the dust in Beijing on April 16 mainly came from dry saline lake basin.

　　　　Saline-alkali desert and chemical dust storm are universal problems in western China.

　　　　Most of China’s salt lakes and dry saline-alkali lake basins are concentrated in the west, and there are 813 salt lakes with an area of nearly 40,000 square kilometers. All the saltwater lakes have more than 100,000 square kilometers, and if the dry lake basins are included, it is much larger than this figure. Some of these saline-alkali dry lake basins are close to North China, Beijing and Tianjin. In addition, there are about 500 million to 600 million mu of saline-alkali land in China, and most of them are distributed in the west of China.

　　　　Zheng Baiyu believes that the phenomenon of saline-alkali desert and chemical dust storm has a profound geographical and geological background. The western part of China is located in the easternmost part of the North Africa-Eurasia desert belt, which is an ancient ocean in ancient times. Since Cenozoic Tertiary, the ancient ocean has begun to shrink back. In the process of evolution, two noteworthy phenomena appeared. First, a large amount of salt in the ocean and saltwater lake remained in the soil during the drying of the lake and sea. Because part of the salt became alkali through alkalization, these soils became saline-alkali soil. Second, large areas of dry sea basins and lake basins have appeared in inland sea and lakes. The sediments in dry sea basins and lake basins are deep, fine and rich in saline-alkali substances. "Some deserts in China are in basins, such as the Taklimakan Desert in the Tarim Basin, which is the result of this evolution. This explains why most sandstorms in China are caused by saline-alkali dust storms. "

　　　　Zheng Baiyu believes that although the chemical dust storm is mainly caused by natural causes, it also has a lot to do with unreasonable human activities, especially the unreasonable use of water resources by human beings, which has an incalculable impact on the environment.

　　　　Controlling chemical dust storm with salt-tolerant pioneer economic plants

　　　　Because the views of researchers such as Zheng Baiyu and Song Huailong have not been recognized by the competent authorities of the state, they have not been supported by the state. However, they started the research and experiment of comprehensive management with their own funds-planting saline-alkali tolerant pioneer economic plant Suaeda salsa to cover the bare grassland saline-alkali spot desert, so as to achieve the purpose of fixing dust and suppressing alkali. The experiment was carried out in Chagannuoer dry lake basin in Ximeng, Inner Mongolia and Angulino dry lake basin in Hebei. After four years of exploration, the experiment has achieved phased results. Based on the experiment of artificial planting of 1000 mu in Chagannuoer in 2003, the coverage area of Suaeda salsa has been expanded to about 10000 mu, of which more than 900 mu have a coverage rate of over 85%. The average plant height is about 60cm；; The average plant weight is 225g g. In this 10000-mu Suaeda salsa coverage area, it can be preliminarily judged that it has basically the effect of dust fixation and alkali suppression, that is, it has shown the ecological control effect of little or no saline-alkali dust in strong wind.

　　　　Several researchers, including Zheng Baiyu, also put forward suggestions for controlling chemical dust storms. First, reform the management system. Preventing and controlling chemical dust storms is a systematic project involving many departments and disciplines, which should be led by an organ that can command, synthesize and coordinate all departments, and is not suitable for a professional department. Second, intensify research, with the national authorities taking the lead in organizing or designating specialized research institutions to carry out research on the evolution of dry lake basins and the prevention and control of chemical dust storms, and collect relevant information as soon as possible; The third is to improve the national monitoring system and testing projects; Fourth, continue the dust source control project; The fifth is to grasp several big projects and experimental projects; Sixth, we are determined to adjust the production mode and production structure of grassland animal husbandry, transform family pastures, implement intensive grassland animal husbandry and build new pastoral areas.

　　First, the extremely cold weather has led to a decrease in supply, and oil prices have reached a one-year high.

　　In February, the average oil price rose by more than 10% compared with January, and the Japanese crude oil contract 07 once broke through the integer mark of 40,000. During the Spring Festival, crude oil production in the United States and Russia dropped sharply due to extremely cold weather. At the same time, the multinational Coalition forces headed by Saudi Arabia claimed to intercept a drone launched by the Houthi armed team allied with Iran, which was full of explosives. Extreme cold weather caused supply disruption and geopolitical events, which caused oil prices to rise unilaterally. However, after the large-scale cold wave weather, the reduced output will gradually recover. At the same time, OPEC+ sources said that in view of the rebound in oil prices, OPEC+oil producers may relax restrictions on crude oil supply after April. Near the weekend, oil prices retreated some of the gains.

　　As of Friday (February 19th), TOCOM Middle East oil futures Wenhua Financial Price Index opened at 37,940 yen at the beginning of the week and closed at 38,990 yen on Friday, up 1,080 yen, or 2.85%, from last week’s settlement price. The crude oil price index of culture, finance and economics is maintained in the range of 37810-40420 yen as a whole.

　　Second, this week’s US EIA data analysis

　　Inventory: As of the week of February 12, the inventory of commercial crude oil excluding strategic reserves decreased by 7.257 million barrels to 461.8 million barrels, a decrease of 1.5%, which recorded a decline for four consecutive weeks and fell to the lowest level since March last year. Gasoline inventories increased by 672,000 barrels, recording growth for four consecutive weeks. Refined oil inventories decreased by 3.422 million barrels, recording a decline for four consecutive weeks and hitting a new low since the week of November 20, 2020 (13 weeks). Cushing crude oil inventories decreased by 3.028 million barrels to the lowest level since March last year.

　　Import and export: As of the week of February 12, commercial crude oil excluding strategic reserves imported 5.898 million barrels per day last week, an increase of 41,000 barrels per day over the previous week. US crude oil exports increased by 1.245 million barrels per day to 3.862 million barrels per day last week. In the past week, the net import of crude oil inventories in the United States decreased by 1.204 million barrels per day.

　　Equipment utilization rate: As of the week of February 12th, the refinery equipment utilization rate increased by 0.1% to 83.1%, and it is expected to decrease by 0.2% to 82.8%. The utilization rate of refineries has risen to a new high since March last year.

　　Output: As of the week of February 12, the domestic crude oil output in the United States decreased by 200,000 barrels to 10.8 million barrels per day last week.

　　Third, other influencing factors

　　According to data released by Baker Hughes, an American oil service company, as of the week of February 19th, the total number of oil drilling wells decreased by one to 305, which was previously expected to increase to 309. The total number of natural gas drilling wells increased by 1 to 91 in the current week; The total number of wells drilled was the same as last week, with 397 wells.

　　The coldest weather in the past 30 years has caused serious damage to the major oil-producing States in the United States. The oil production has plummeted by more than 2 million per day, and these States had almost no need to deal with the Arctic storm. Consulting firm Energy Aspects Ltd estimated that as of Monday, the refining capacity in the United States had decreased by 3.1 million barrels per day. According to people familiar with the matter, Total’s refinery in Port Arthur, Texas, shut down the coking unit, with a capacity of 225,500 barrels per day. Total is also preparing to shut down the crude oil distillation unit of the refinery, which decomposes crude oil into hydrocarbon raw materials for all production equipment of the refinery. Due to severe cold weather in Texas, the largest oil refinery in North America was closed. According to an email from Motiva Enterprises LLC, the company will stop the operation of its refinery in Port Arthur, Texas. It is reported that the crude oil production in the Permian basin was frozen due to severe cold weather, and the crude oil production in the United States fell by more than 40% or 4 million barrels per day. Anadarko basin also has a large reduction in production.

　　According to people who know the production data, from February 1 to 15, the average daily output of crude oil and condensate oil in Russia was 1.38 million tons. This is equivalent to a daily output of 10.115 million barrels, which is about 44,000 barrels lower than the January level. Due to the extremely cold weather, some manufacturers cut off the flow of oil pipelines.

　　According to the Wall Street Journal (blog, Weibo), Saudi Arabia will increase its oil production when the oil price picks up, and plans to increase production in the next few months, so as to reverse the big reduction in January and increase production by as much as 1 million barrels a day. India’s oil minister also urged OPEC+to relax production cuts on Wednesday. It should be noted that the official position of Saudi Arabia is more cautious. Before the news from foreign media came out, the Saudi oil minister expressed the hope that the oil market would not be complacent and it was too early to announce the victory over the virus. It will not send a signal of OPEC+oil production reduction in the future. I hope that oil traders will not try to predict the trend of OPEC+.

　　The multinational Coalition forces headed by Saudi Arabia claimed to intercept a drone launched by the Houthi armed team allied with Iran, which was full of explosives. Prior to this, Houthi armed forces attacked an airport in the southern border area of Saudi Arabia.

　　CEO of Gazprom, a Russian gas company: Global oil demand has not recovered, but we have seen a positive trend. It is difficult for oil prices to stay above $60/barrel. Oil demand may return to the pre-crisis level next year. It is more appropriate to keep the oil price between 45-60 USD/barrel.

　　American officials said that the United States is willing to hold a dialogue with Iran at the six-nation meeting on the Iranian nuclear issue hosted by the European Union. For the first time in the United States, officials have loosened up.

　　According to the announcement by the Texas Electric Power Reliability Committee (ERCOT) that the local energy emergency has been cancelled, it is said that the local power grid has returned to normal. Many oil miners, including Marathon Oil Company, are taking advantage of the power grid and generators to restore power supply to resume production. The Texas oil field in the United States is slowly starting to restart drilling work. Previously, due to the southward movement of polar cold air, there was a historic drilling stoppage in the area involved in the oil field.

　　According to local media reports in Angola, Di Mantino Azevedo, Angola’s Minister of Mineral Resources and Petroleum, recently said in Luanda that Angola’s oil production only accounts for 20% of domestic daily consumption demand, while the rest of the oil consumption is imported from abroad. The minister said that Angola imported nearly 3 million tons of refined oil in 2019 and spent more than 1 billion US dollars. This import requires a lot of foreign exchange expenditure, which can be used for public investment and other expenditures in Angola. At present, in order to reverse this trend, the Angolan government has formulated a strategic plan for oil refining, which includes the construction of oil refineries in Cabinda, lobito and Soyo, and the modernization and optimization of Luanda oil refinery.

　　According to Iranian state television, Iranian Deputy Foreign Minister Rogochiy said in a television interview on the 21st local time that borrell, the European Union’s High Representative for Foreign Affairs and Security Policy, said that an informal meeting would be held to invite the Iranian nuclear deal participants and the United States. At present, Iran is considering and discussing the proposal with relevant parties, and will respond to it later. But at the same time, Rogochiy said that there is no need to discuss the return of the United States to the Iranian nuclear deal and fulfill its commitments. The only way is to lift the sanctions against Iraq, and some technical and implementation issues can be negotiated by borrell and others.

　　Fourth, the forecast of the market outlook

　　According to the latest news, the power grid in Texas has been restored and the oil industry is restarting production, which means that the fear of supply interruption caused by extremely cold weather will gradually disappear. The focus of the market will continue to shift to changes in the supply side. At present, the relationship between the United States and Iran is slowing down, and due to the rebound of oil prices, OPEC+ oil producers may relax restrictions on crude oil supply after April. Concerns about increased supply impose oil prices. Recently, oil prices have risen sharply, climbing to a one-year high. Oil prices are at risk of a short-term correction.

Mycoplasma pneumonia, COVID-19, A stream, B stream …

near future

Many people are "hit" by various respiratory viruses.

November 22nd.

# Syncytial Virus # ranks first in Weibo Hot Search.

Some netizens asked, "What is this!"

Syncytial virus

It’s not a new respiratory disease

It has already appeared this summer.

An out-of-season epidemic

With the coming of winter, the temperature drops, and syncytial virus enters the high-incidence season. Wang Quanyi, deputy director of the Beijing Municipal Center for Disease Control and Prevention and chief expert of epidemiology, said that in Beijing, mycoplasma pneumoniae is not the first cause of pediatric visits, and the top three are influenza, adenovirus and respiratory syncytial virus (RSV). Syncytial virus rose to the third place.

Gao Weiwei, chief physician of neonatal respiratory department of Guangdong Maternal and Child Health Hospital, said that syncytial virus infection is the first cause of hospitalization of infants under 1 year old, and 95% of children may have been infected with syncytial virus before 2 years old. In the high epidemic season, more than 80% of infants’ acute lower respiratory tract infections are caused by syncytial virus infection.

What are the typical symptoms?

Who should pay special attention to?

How to effectively prevent it?

Spread through droplets and close contact

Children and adults can be infected.

▼

Syncytial virus is an RNA virus, which is transmitted by droplets and close contact, or by contaminated hands and objects. Patients often have upper respiratory symptoms after infection.

The incubation period of syncytial virus is usually 2-8 days, and detoxification can last for 1-3 weeks. Early infection is mostly confined to the upper respiratory tract, showing symptoms of upper respiratory tract such as nasal congestion, runny nose, cough and hoarseness.

The typical symptoms of children infected with syncytial virus are fever, cough, stuffy nose and runny nose.

The typical symptoms of adult infection are very similar to the common cold, such as low-grade fever, cough, stuffy nose and runny nose.

Most patients’ symptoms will disappear spontaneously within 1-2 weeks, and a small number can develop into lower respiratory tract infection (i.e. bronchiolitis or pneumonia), which is more common in young infants. Clinical symptoms include cough and wheezing.

Syncytial virus is about 2.5 times as contagious as influenza.

Infection among older children has increased this year.

▼

Gao Weiwei, chief physician of neonatal respiratory department of Guangdong Maternal and Child Health Hospital, said that syncytial virus is about 2.5 times as contagious as influenza. If children are seriously infected with syncytial virus at the age of 0-1, it may have a serious impact on their lung function, even for a long time.

Syncytial virus, like Covid-19 virus and influenza virus, spreads through respiratory tract, causing respiratory symptoms such as fever, cough, stuffy nose and runny nose, but there are some differences.

Similarities and differences of three viruses. Source: Popular Science China

It is reported that respiratory syncytial virus (RSV) in southern China experienced a wave of epidemic peak this year. After a short decline, it rose again as the temperature dropped. For children, RSV and influenza are easy to attack in groups. Moreover, respiratory syncytial virus mostly occurred in children younger than 2 years old in previous years, and the infection of older children has increased this year.

There are no vaccines and specific treatments.

Repeated infection, prone to family transmission.

▼

At present, there are no syncytial virus vaccines and special therapeutic drugs on the market in China. Syncytial virus can be repeatedly infected, and it is also prone to family transmission. In the absence of vaccines and effective drugs, measures such as strengthening personal protection should be taken to prevent infection:

In the epidemic season of syncytial virus, try to avoid going to crowded places;

Wear a mask when going out, and pay attention to cover when sneezing;

Pay attention to hand hygiene, do not touch, wash your hands frequently;

Personal protection should be done in medical institutions to prevent cross-infection in hospitals.

Xinhua news agency data map

Except syncytial virus

Pay special attention to influenza virus in the near future.

The incidence of influenza in Guangdong has increased significantly since September.

▼

On November 23rd, the latest weekly influenza surveillance report released by the National Influenza Center showed that the proportion of influenza-like cases in sentinel hospitals in southern provinces reached a new high in the past three months, reaching 6.4%, which was higher than that in northern provinces (6.2%). About 30% of influenza-like cases were tested positive, and the positive rate of influenza in southern provinces was higher than that in northern provinces.

According to the notification of infectious diseases in Guangdong Province, the number of influenza cases in Guangdong has increased significantly since September, reaching a new high in the past six months in October. Guangdong CDC issued a document four times recently, calling on the public to actively vaccinate against influenza.

Dry weather is conducive to the survival and spread of influenza virus.

Ying Qin washes his hands and wears a mask to get the flu vaccine.

▼

@ Guangdong Weather Release Reminder: It is expected that in the next few days, Guangdong will still maintain dry weather, and low humidity is conducive to the survival and spread of influenza virus. How to avoid children’s respiratory tract infection?

Experts generally suggest that you should wear masks in public places, try to avoid going to crowded places, wash your hands frequently, drink plenty of water, have more ventilation, and get the flu vaccine as soon as possible.

Yin Genquan, deputy director of the internal medicine department of Guangzhou Women and Children Medical Center and chief physician of the respiratory department, also said that from the perspective of increasing children’s resistance, the best "medicine" is four words: correct care, comprehensive nutrition, proper exercise and happy mood.

Children with mild symptoms can consider home observation.

Avoid cross infection

▼

At the peak of pediatric visits, Yang Jinghua, director of the Pediatrics Department of Guangdong Provincial Hospital of Traditional Chinese Medicine, suggested that if older children have mild symptoms, good mental state and no obvious refusal to eat or drink, they can consider home observation to reduce the risk of cross-infection when seeking medical treatment. However, please take your child to see a doctor in time in the following situations:

Infants under 3 years old have fever and cough.

High fever persists.

Repeated fever cannot be relieved for more than 2-3 days.

Poor mental state, listlessness, lethargy

Severe cough, shortness of breath, difficulty breathing, etc.

Mo Xiaolan, deputy director and chief pharmacist of the Pharmacy Department of Guangzhou Women and Children Medical Center, said that no matter what kind of pathogen is infected, the general principle of medication for children with acute upper respiratory tract infection is to rest, drink plenty of water and deal with symptoms. "If you don’t use drugs, you don’t use drugs. If you can use only one drug, you don’t need multiple drugs. If you can take it orally, you don’t need intravenous infusion."

Are there many people around you who have a cold and fever recently?

Forward it to your relatives and friends to remind each other!

The news that Xiamen aunt bought gold bars for one million yuan brought some warmth to the frozen gold market.

It is reported that as the price of gold fell to a low level in ten and a half months, many gold investors acted quickly. In the past few days, several "Xiamen aunts" have been buying gold. Among them, an "aunt" bought 3.75 kilograms of investment gold bars in a bank in Xiamen for a total price of 1 million yuan.

Since Trump won the US presidential election on November 8, the US dollar index has risen by 5%, while the international gold price hit a peak of more than $200 that day, and last week, it hit a low of $1,122.35 per ounce for more than 10 months.

Some market participants have analyzed that in terms of value investment, the current price of gold and silver is close to the cost price of mining, and there is not much room for further decline. In this context, China and Indian-dominated major gold sales markets are about to usher in a buying boom. Especially in China, near the end of the year, there are many festivals, and the golden aunts have begun to itch to try. Reflected in the price of gold, the current price of London gold is weak, indicating that "Chinese aunt" and "Indian uncle" have begun to enter the market.

Gold was shocked by a drop of $200.

Since Trump was unexpectedly elected president of the United States, the global gold price has started a crazy decline mode, and has retreated the increase in the first half of the year in one fell swoop, falling more than 200 dollars since the beginning of November. According to industry analysts, the main reasons for the decline in gold prices include that the US economic recovery is expected to strengthen, the Federal Reserve completed the interest rate hike in December and made positive remarks, and the physical demand in India is weak.

Looking back on the coming year of 2016, the performance of gold can be described as ups and downs: the first half of the year was hot. Since the Brexit in July, the price of gold reached a one-year high, while in the second half of the year, it went out of the opposite trend, with the price of gold falling endlessly and hitting new lows all the way.

Yang Yi, an analyst at Meichuang Huanyu, told china securities journal that the market agreed that the policies implemented by Trump after he took office would accelerate the recovery of the US economy, and then the Federal Reserve raised interest rates for the first time in the year, raising interest rates by 25 basis points to 0.5%-0.75% in December, raising the long-term federal funds interest rate to 3%, becoming the second interest rate increase after the subprime mortgage crisis in 2008. At the same time, the interest rate hike cycle is expected to strengthen, and the US dollar index hit a new high, trading around 103 points, hitting a new high in 2016. "Generally speaking, because the trend of gold and the dollar is in the opposite direction, while the US dollar index hit a new high, gold was suppressed by it, and the price continued to fall. The intraday market went out of a roller coaster-like market. So far, gold has almost retreated all the gains." She said.

Gong Wenjia, a researcher at Shiyuan Jinxing, believes that after Trump was elected president of the United States, the market expected the direction of the American economy, especially the illusion of its tax cuts and manufacturing return, which promoted the rise of risky assets.

In addition, India’s physical demand for gold has also declined this year. The high volatility of gold price and the Indian government’s crackdown on black money have weakened the demand for gold. In the first nine months of this year, the country’s total gold consumption was 442.3 tons, which was about 30% lower than the same period of the previous year.

Holiday demand is expected to start.

This year’s New Year is approaching, and it is the Christmas holiday in the west. The major shopping malls are full of festive atmosphere. However, the reporter found from the gold market such as Beijing Caibai that the number of uncles and aunts who came to buy gold did not increase significantly compared with the past.

An on-site staff member told china securities journal that most investors have made profits, and the short-term gold trend is subject to the fluctuation of the dollar at the bottom, so the market trading is very light. At present, the whole market is on the sidelines, and Chinese aunts are no exception. With regard to the trend of gold in 2017 and the upcoming consumer holiday in China, he predicted that the trend of the US dollar will "peak" in the future, and the overall fundamentals of gold are slowly improving. Under the influence of various favorable factors, the market will once again see the figure of Chinese aunts, and gold may close up to welcome the New Year.

Yang Yi, who has been engaged in gold market research for a long time, believes that the demand for gold in China market will increase as the Spring Festival approaches. At the same time, the gold price has continued to fall recently, and the RMB is also depreciating against the US dollar. These factors have caused Chinese aunts to start snapping up the mode one after another.

She said that on the one hand, the demand for gold by mainland residents represented by "Chinese aunts" is increasing periodically as the Spring Festival is approaching at the end of the year, and on the other hand, the scale of gold outflow from gold exchanges in the domestic financial market is reaching a record high; Chinese aunts are about to start the "buy buy Buy" mode. However, similar to the bargain-hunting at the end of 2015, this time the aunt entered the market to buy gold at a time when the Federal Reserve raised interest rates and the RMB exchange rate plummeted. In particular, the "boots" of the Federal Reserve’s interest rate hike have already landed, and the expectation of interest rate hikes is gradually dissipating. As long as the gold price shows signs of rebounding, the Chinese aunt will act immediately.

Zhou Yupeng, a precious metal analyst at Netease, believes that in terms of value investment, the current price of gold and silver is approaching the cost price of mining, and there is little room for further decline. In this case, the main gold sales markets, mainly China and India, are about to usher in a buying boom. In China, near the end of the year, there are many festivals, and gold aunts in China have started to buy gold. Reflected in the price performance, there has been a short-selling phenomenon in London gold, indicating that China Golden Aunt and Indian Gold Uncle have started to enter the market.

The hunters should be careful.

Many analysts said that after Trump was elected president, the market’s confidence in the US economic recovery increased and the US dollar was supported. At the same time, the Federal Reserve completed the interest rate hike in December, and said it would increase the rate hike in 2017. In an environment where the dollar is strong, it is more likely that the price of gold will continue to fall.

"In the last week of this year, the risks faced by the gold market are still biased downwards. In addition, this week is Christmas Day and the end of the year is approaching. The trading of precious metals will be relatively light, and it will also face the selling pressure of clearing accounts at the end of the year. Therefore, hunters should be careful." Yang Yi said.

She believes that the trend of international gold prices is constantly declining due to the interest rate hike by the Federal Reserve and the US presidential election. US stocks and the US dollar are already high, facing the pressure of callback. In particular, the US dollar has hit a 14-year high, which is also the high level after the US election. It will face certain resistance if it continues to rise. At present, it is difficult for the US dollar index to reach a new high. Although the gold price trading is weak around $1,135 and there are signs of a slight rebound, the trend is still not optimistic. At present, the gold bull market still lacks fundamental support. Next year, basic fabrics will tighten, and gold production may decline. However, the currency problems of China and India’s major consumer countries may cause investors to buy gold to hedge and boost demand. It is still too early to bargain-hunting.

Gong Wenjia said that from a technical point of view, it has been fluctuating at 1120-1150 USD/oz for many days, and whether the bottoming can be successful needs further confirmation. Therefore, considering comprehensively, it is more likely that the price of gold will continue to fall under pressure.

Will it shine again in 2017

"There is a rule in the gold market, that is, whenever the US president changes people, it is not far from the low point of the gold market." According to market statistics, George W. Bush came to power in 2000, and in 1999 and 2001, it was the time when the price of gold hit a multi-year low of more than 250 US dollars per ounce and made a double bottom. In 2008, when Obama came to power, he was catching up with the financial crisis. The price of gold dropped by more than 30% from the high of $1,032 per ounce to $681 per ounce. Trump was elected president this time, after the gold price hit a five-year low of $1,042 per ounce at the end of 2015. But it seems likely that this is not the lowest point, and the gold market is likely to go out of the double bottom again. The reason is that the Federal Reserve just raised interest rates for the second time in 10 years, pushing the dollar higher, and plans to raise interest rates three times next year. The US dollar index rose from 98 to 103, a 14-year high. After Trump takes office, he will implement measures such as tax cuts and increased investment in infrastructure, which may promote the good expectations of the economy and make the gold market not optimistic.

However, Zhou Yupeng believes that the long-term devaluation of currencies is a trend due to the currency overshooting in various countries, and gold is bullish as a value-preserving variety for a long time. In addition, there are still many risk events that can be expected in 2017. The European election year is coming, populist forces are on the rise, and the voices of countries demanding to leave the European Union are rising. In 2017, the safe-haven demand for gold may be pushed up, thus prompting the price of gold to rise. Recently, terrorist attacks around the world have continued, which has also pushed up the safe-haven property of gold and pushed up the price of gold to some extent.

He said that from the perspective of long-term investment, the future bullishness of gold is the theme. Don’t be confused by the immediate setbacks. You can start with some gold by holding it in batches, so as to protect your asset value in the future inflation.

Recently, Qi Song, the "assassin in the workplace" in "20 Don’t Confuse 2", made frequent comments on the Internet, and was evaluated by the audience as "everyone’s Internet mouth replacement".

　

Qi Song (Fei Qiming) is smart, creative, romantic and gentle, and warms the person he likes like a little sun, with 100% healing power!

At work, he is an anti-anxiety and anti-involution person.

　

When the project encounters problems, Qi Song will not keep working overtime to put pressure on himself like ordinary people, but will open up new ideas for himself by entertainment.

When the project was completed, but the leader stepped in to grab the work, Qi Song dared to resist the angry leader.

　

In feelings, he is a walking generator.

　

Qi Song and Xiao Guo (Guanjin Bu) look at each other in the power-off office. It’s hard not to be moved by this atmosphere!

Although on the surface, they always quarrel and play like chickens in primary school, in fact, Qi Song has a crush on Jiang Xiaoguo (Guanjin Bu) since high school. When I was in college, I went abroad for further study. After becoming more independent and excellent, I returned to Xiaoguo to provide her with energy.

　

Xiaoguo introduced his name as "small" and "fruit" of fruit.

Qi Song said that it was the other mountains all appear dwarfs under the sky.’s "small" and fruitful "fruit".

This is the so-called "beauty is in the eye of the beholder" ~

　

Xiao Guo’s speech after drinking for a long time was recorded by a willing heart and sent to the company group for "public punishment". Qi Song will immediately use the expression pack to screen the screen to ease her embarrassment.

　

When two people encounter difficulties in a cooperative project, he always tries his best to solve them and become the most solid back of Xiaoguo.

I can not only fight with her, but also struggle with her. When I get along, I am a happy maker. At the critical moment, I am the best partner who is calm and reliable. Please give me a dozen of this kind of boyfriends!

　

Qi Song’s anti-involution and anti-anxiety "workplace assassin" is rare in domestic workplace dramas, and his debut experience as a player, Fei Qiming, is like an "assassin" and unique in the entertainment industry.

　

In 2017, several ten-second videos made Fei Qiming, who was still in college, become the first generation of online celebrity in Tik Tok, and created a unique school grass style with gold-rimmed glasses and boyish smile. However, in the booming era of short videos, Fei Qiming has set his sights on the entertainment industry.

In 2018, Fei Qiming began to "de-online celebrity" and participated in the popular variety "Happy Camp". His popularity on the Internet remained high, and his road to transformation officially began.

　

In the same year, he received an invitation to audition for the school play "I am waiting for you in the future" and partnered with Qian Sun, Xin Yunlai and other new generation actors. In the play, he plays Liu Dazhi, an optimistic boy, who not only won the recognition of Li Guangjie, an old opera player, for his courage of being a newborn calf, but also reversed the questioning voice before the broadcast because of his natural performance and true feelings. This is the first step in his transformation from online celebrity to an actor.

　

But because I devoted myself to filming and didn’t update Tik Tok for a long time, I lost a big wave of fans. For the gains and losses, Fei Qiming is very calm: "I hope I can sink and be seen when I look up."

　

However, the popularity of a drama series didn’t make him completely get rid of the label of Tik Tok online celebrity. What really made Fei Qiming break through was various popular variety shows.

　

From his debut in 2018 to the present, Fei Qiming has won a total of 8 variety shows. Among them, Iqiyi’s parent-child reality show "Super Kindergarten", RV travel reality show "Flower Road of Youth", Tencent’s video beauty program "Prince Lipstick", and now the popular variety "Fifty Kilometers of Peach Blossom House" and other variety shows have his figure.

　

Now, he not only proved his talent and hard work in performance again in "Twenty Don’t Confuse 2", but also a large wave of dramas to be broadcast filled the audience’s expectations.

　

For example, the sci-fi drama Orphan of Mars, adapted from the novel of the same name by science fiction writer Liu Yang, in which Fei Qiming plays the man Guhe.

Although his debut is only four years, and there are only a handful of film and television works, Fei Qiming, who was born in online celebrity, is full of love for acting. When talking about the career of actors, he said that "actors only have a starting point and no end point; The sense of crisis as an actor is everywhere. "

　

There are many people who want to lose weight, but very few people can really reinvent themselves. Fei Qiming is one of them. At the age of 17, Fei Qiming was a little fat man weighing nearly 200 Jin. However, in a few years, he turned into a sunny male god on the university campus. After entering the entertainment industry, he set up a special area at home to study scripts and feel the lives of different roles in order to hone his acting skills.

In line with the image of "little sun in the workplace" on the screen, he is also a versatile big boy in reality.

Not only is he proficient in playing and singing, but he also writes well. A little brother who is handsome and can sing and act ~

From the figure counterattack to the transformation actor, his dedication perfectly explains that down-to-earth talents can accumulate thick hair. I believe that Fei Qiming in the future will make constant progress and realize his dream of "becoming a good actor".

　　Beijing Agricultural College pays attention to the advantages of urban agricultural talents, technologies and platforms, promotes the coordinated development strategy of Beijing-Tianjin-Hebei and the rural revitalization strategy as a whole, and carries out technical extension services around the needs of sweet potato breeding and planting in vast areas of Hebei to promote the green, high-quality and high-yield development of sweet potato industry.

　　I. Basic information

　　Hebei province is the main producing area of sweet potato in China, with a long planting history. In recent years, the planting area has stabilized at about 2 million mu. Because of drought and flood, sweet potato is called a hard-core crop by growers. However, there are still some problems in the old sweet potato planting areas in Hebei Province, such as variety degradation, extensive planting techniques, pests and diseases caused by repeated cropping for many years and so on. Since 2006, the sweet potato breeding and planting team of the College of Plant Science and Technology of Beijing Agricultural College has gone deep into the Beijing-Tianjin-Hebei region, adhered to the close combination of field and classroom, theory and practice, research and development and popularization, innovation and service, and brought a lot of practical information and technology to sweet potato growers, covering 11 prefecture-level cities and more than 60 counties such as Baoding, Langfang, Chengde and Zhangjiakou in Hebei, and established a stable service cooperation relationship with Shuanghua Agricultural Products Planting Professional Cooperative in Gu ‘an County of Langfang, which radiated Beijing-Tianjin-Hebei. Zhao Bo, the team leader, was awarded as "Advanced Individual in Rural Work in Beijing (2017-2021)".

　　Second, the implementation progress

　　(1) Demonstration and popularization of new sweet potato varieties. For a long time, the first generation varieties accounted for about 50%, the second generation and the third generation varieties accounted for about 30% in the production of sweet potato in the vast area of Hebei, and the variety upgrading was lagging behind, which could not meet the demand of sweet potato producers for economic benefits or consumers for fresh sweet potato quality, thus affecting the development of sweet potato industry in this area. Since 2016, the sweet potato team has successively introduced the fifth-generation sweet potato varieties, such as Pushu 32, Yanshu 25, Longshu 9 and Shangshu 19, in Langfang, Chengde, Zhangjiakou and Tangshan, which made the local sweet potato variety structure jump from the first generation to the fifth generation at that time, the yield level was improved, the quality was obviously improved, which met the market requirements for the taste and appearance of fresh foods, the income of growers was guaranteed, and the introduced new varieties were obtained.

　　(two) demonstration and popularization of cold bed seedling technology. The method of raising seedlings with fire resistance is a common method of raising seedlings of sweet potato in North China. The seedbed is simple in structure and convenient to build. Coal, straw and firewood can be used as heating materials, and it is easy to obtain materials, but there are also problems of high energy consumption and serious environmental pollution. However, the method of multi-layer covered cold bed seedling raising in solar greenhouse or small and medium shed can meet the temperature requirements of sweet potato seedling raising without heating, eliminating the consumption of fuel and electric energy, greatly reducing the cost, and eliminating the pollution of coal burning and burning straw to the atmospheric environment, which has ecological benefits of energy saving and emission reduction. The sweet potato team took the lead in popularizing advanced cold bed seedling raising technology in Gu ‘an County of Langfang, lulong county of Qinhuangdao, yutian county of Tangshan and other places, and implemented systematic improvement in facilities selection, seedbed construction, seed potato stacking, soil covering thickness, temperature control, disease control and other aspects, so that the weight of 100 potato seedlings was increased from 250 grams to more than 500 grams, reaching the standard of strong seedlings, the seedling quality was significantly improved, and the energy consumption and pollution were significantly reduced.

　　(3) Vigorously support industrialized seedling raising. Industrial seedling raising is an important guarantee for obtaining excellent provenance. For a long time, most of the sweet potato seedlings in Beijing-Tianjin-Hebei region were propagated by farmers for their own use or transferred from neighboring provinces. There are some problems such as relatively backward breeding technology, uneven quality of potato seedlings, untraceable production losses caused by fake and inferior potato seedlings, and uncertain supply time. Focusing on the cultivation of excellent seed potato seedlings, the sweet potato planting team started with rapid propagation technology and supported the new agricultural management entities to implement factory seedling raising. In 2019, we began to cooperate with Shuanghua Agricultural Products Planting Professional Cooperative in Gu ‘an County, Langfang, to establish a standard chemical plant seedling base, carry out large-scale seed potato seedling cultivation, and provide service guidance from production management, technical training and market development. In the past three years, the annual output of high-quality sweet potato seedlings has reached about 35 million, and the application area has reached more than 12,000 mu. The application scope includes Beijing-Tianjin-Hebei, Henan, Hubei, Hunan, Liaoning, Inner Mongolia, Shandong, Shanxi, Shaanxi, Xinjiang and other vast areas, effectively reducing costs, effectively curbing the phenomenon of indiscriminate introduction, proliferation and sales of seed potato seedlings in the market, and making sweet potato growers affordable and comfortable to use.

　　III. Main Features and Effects

　　(A) technology research and development and technology promotion are closely integrated. Scientific research "originates from production and is used for production". The sweet potato breeding and planting team insists on demand-oriented and problem-oriented, so that tasks come from production, demand, market, scientific research results go to production, farmers and enterprises, so as to accelerate the transformation of agricultural scientific and technological innovations into real productive forces and write the "Sweet Potato Paper" on the land of Yanzhao. For more than ten years, while breeding marketable sweet potato varieties, the sweet potato team has successively promoted and applied more than 10 green, high-yield and high-efficiency production supporting planting management technologies such as virus-free seed potato rapid propagation, high-temperature healing seed potato storage, cold bed laying seedlings, seedling bed soil disinfection, etc. around sweet potato stem tip virus-free and improved seed breeding in vast areas of Hebei, with an average annual planting scale of over 10,000 mu, thus escorting the sweet potato industry to improve quality and efficiency. For example, in view of the safe storage of seed potatoes in winter, the storage technology of high-temperature healing seed potatoes is adopted to reduce the rotten rate of seed potatoes and improve the vitality of seed potatoes; The soil disinfection method combining sunlight, irrigation and chemicals effectively eliminated the soil-borne diseases of sweet potato; Adopting the technical process of virus-free sweet potato two-stage seedling breeding, the tissue culture seedlings directly produce the original seeds, which improves the quality by one level, advances the time by one year, reduces the production times of seed potatoes in the soil, and makes the seedlings cleaner.

　　(2) Online and offline technical services are not dropped. At the beginning of 2020, there was a once-in-a-century epidemic in COVID-19. For a long time, although the flow of people was restricted, the scientific and technological service activities of the expert team did not stop. According to the time, place and classification guidance, they worked "continuously" and served "continuously", which minimized the impact of the epidemic on agricultural production and ensured the smooth flow of agricultural technology services in the last mile. Especially in the early stage of the outbreak, faced with various uncertain factors, the expert team actively provided online guidance to 21 sweet potato seedling enterprises in Chengde, Langfang, Tangshan and Baoding through WeChat and telephone, helping to solve the technical problems of large-scale sweet potato seedling farmers in time. In March, 2020, Langfang area issued blue warning of gale for many times, and the expert team immediately telephoned 12 seedling farmers in Xueputou Village, Gu ‘an County to reinforce 110 plastic greenhouses and 4 solar greenhouses, thus avoiding losses in time.

　　(3) Supporting new agricultural business entities and highlighting the effect of linking agriculture with agriculture. Compared with traditional small farmers, new agricultural business entities, such as large-scale farmers, family farms, farmers’ professional cooperatives and leading enterprises in agricultural industrialization, are large-scale, specialized, intensive and market-oriented, which have unique advantages in linking agriculture with agriculture and can give consideration to both economic and social benefits. In the process of technology promotion, the sweet potato breeding and planting team has signed a technical service agreement with Shuanghua Agricultural Products Planting Professional Cooperative in Gu ‘an County of Langfang since 2019, forming a working mode of interest community of "expert team+village collective+cooperative+farmer". Through the effective mechanism of benefit sharing and risk sharing, the annual output value of the cooperative is supported to reach 3-5 million. Under the guidance of experts’ regular service, the cooperative nursery bed is stable at 30,000-50,000 square meters all the year round, which can directly provide 50 stable jobs every year, with 100 workers in busy farming hours, and at the same time, radiation drives more than 1,000 employees in surrounding planting, deep processing and logistics, and gradually forms a sweet potato industrial chain integrating seedling raising, planting, storage and sales.

　　(4) Go deep into the fields and send the technology to the hearts of farmers. The promotion and upgrading of new sweet potato varieties should be closely combined with the promotion of planting techniques to achieve higher efficiency. In view of the fact that there are few young and middle-aged laborers in rural areas and the elderly have become the main force of agricultural production, the expert team explored the technology of close planting and shallow planting of sweet potato, which controlled the shape of sweet potato by adjusting the planting density, and increased the number of potato nodes by planting sweet potato seedlings in the soil, thus achieving the purpose of increasing yield and reducing labor intensity. Of course, the promotion of new technology is a slow process, limited by traditional habits, knowledge structure and cognitive level. Older growers don’t recognize new planting technology, and often experts just leave after class, and farmers still do it in their own way. In order to verify the outstanding effect of the new technology, the team of experts intervened in the whole process of sweet potato production, and demonstrated and guided the whole process from sweet potato seedling raising to mature harvesting, guiding farmers to change their concepts with facts and reality. In the past 10 years, team members have gone to the countryside for more than 1,500 days, and trained more than 300 farmers every year on average. By promoting new varieties and technologies, many villagers who are unable and unconditional to go out for employment have realized income generation at their doorsteps.

　　Fourth, experience and enlightenment

　　(1) Build a platform. The development of technology extension service can not be separated from the corresponding work platform. The school has incorporated the sweet potato planting and breeding promotion into the overall layout of serving the coordinated development of Beijing, Tianjin and Hebei, and established poverty alleviation workstations, professor workstations, doctoral workstations and technology transfer sub-centers in Chengde, Zhangjiakou and Tangshan, respectively, to promote the collaborative interaction among universities, research institutes, local governments and new agricultural business entities, and promote the integration of Industry-University-Research through the expert team’s on-site service, so as to make the promotion service site a gathering place for talents of agriculture, rural areas and farmers, an experimental field for scientific and technological innovation, and an incubator for the application of achievements.

　　(2) Based on demand. To carry out technology promotion, we should consider whether enterprises need it, whether farmers accept it, and whether the market supply and demand are reasonable, so as to truly solve the pain points in the agricultural industry. To this end, even if you spend more time on research, the so-called "sharpening the knife without cutting the wood by mistake." All the technologies around sweet potato stem tip detoxification and improved seed breeding are born in response to production problems and should be promoted by market benefits. If they are not combined with production and ignore market feedback, even advanced technologies will have no value of popularization and application.

　　(3) carry forward feelings. The main battlefield of technology popularization is the grass-roots front line, which is often arduous and backward. To be effective, the promotion work needs to run around mountains, ravines and fields all the year round. It is consistent with a kind of dedication, selfless feelings and selfless feelings. If you always consider the gains and losses, you can’t do the promotion work well. Making friends with farmers, the sweet potato planting team can not only sit and talk, but also act. Together with sweet potato growers, they are sweating in the hot sun, braving the heat, winning the trust of farmers, promoting stable and lasting cooperation and achieving a win-win situation.

　　V. Plans for further promotion

　　(1) The promotion and demonstration of new sweet potato varieties are uninterrupted. Continue to strengthen the promotion of new sweet potato varieties in Chengde, Tangshan, Zhangjiakou and Langfang, Hebei Province, and radiate to Jinghai, Tianjin, Nanyang, Henan Province and Yiyuan, Shandong Province.

　　(2) The demonstration and promotion of cold bed seedling raising technology of sweet potato is uninterrupted. The system integrates various technologies such as seedling site selection, seedbed construction, seed potato stacking, soil covering, pest control, environmental condition control, seedling quality control, seedling collection and so on, and continuously improves the popularization and demonstration system of sweet potato cold bed seedling technology to enhance the scale of sweet potato cold bed seedling in Hebei Province.

　　(3) Continuous technical training and consultation. Fulfill the duties of scientific and technological workers, strengthen the responsibility of scientific and technological workers, insist on putting their feet in the soil and writing papers on the earth, go to villages and households to guide improved varieties and good methods, disseminate technical essentials, cultivate a group of soil experts, Tian Xiucai and new farmers, and ensure that the "standardized" application of sweet potato breeding and planting technology is effectively transmitted.

　　Reading tips

　　On April 24th, the 14th meeting of the 12th the National People’s Congress Standing Committee (NPCSC) adopted the revised draft of the Advertising Law. The new law clarified the specific situation of false advertisements, intensified the crackdown, and set clear norms for Internet advertisements. Can this law, which was promulgated and implemented for the first time in 20 years, control all kinds of advertising chaos and adapt to the rapid development of advertising platforms? The public is full of expectations.

　　Relying on the economic prosperity, the advertising industry has developed strongly, affecting people’s choices in life, ranging from buying a house, buying a car and traveling abroad to clothes, shoes, socks and napkins.

　　However, ubiquitous and pervasive advertisements provide convenience and also bring troubles. False advertisements, spam messages and all kinds of chaos make people realize the urgency and importance of regulating the advertising market.

　　Irresistible illegal advertisements

　　"It only takes one day, and the teeth are really white!" This is probably one of the most expensive advertising words in history-because of false propaganda, Guangzhou Procter & Gamble Co., Ltd., the advertising subject, was fined 6.03 million yuan by Shanghai Industrial and Commercial Bureau, which is the biggest fine for false and illegal advertisements in China at present.

　　These eye-catching advertisements frequently appear on TV programs, outdoor advertisements and street flyers. Although the current advertising law has clearly stipulated that "advertisements shall not contain false contents and shall not deceive and mislead consumers", many businesses and media prefer to take risks for the sake of high profits.

　　The chaos in the advertising circle is far more than a kind of false advertisement. Some TV stations publish advertisements for health care products in the name of health programs. Some websites pop up several small windows as soon as they are opened, covering the whole screen; Some advertising companies rely on spam messages and spam to "sow widely and reap sparingly"; Others stand on the main road and make small advertisements …

　　Why are illegal advertisements repeatedly banned? This is related to the fact that the current advertising law is too principled and not binding. Zhang Mao, director of the State Administration for Industry and Commerce, said that in recent years, with the rapid development of China’s advertising industry and the wide application of the Internet, the media and forms of advertising have changed greatly. Compared with this, the advertising law promulgated and implemented in 1995 still has some problems, such as the incomplete content of advertising general rules, unclear advertising activity norms, unclear standards for identifying false advertisements, and weak operability of legal responsibilities, which makes it difficult to effectively curb advertising violations.

　　In addition, the low illegal cost is also an important reason for enterprises to violate the law frequently. Take "the most expensive advertising words in history" as an example. Although 6.03 million yuan is already the biggest ticket issued by the administrative department, the annual sales of only one brand under P&G’s name exceeds 6 billion yuan, and the "sky-high ticket" is really insignificant.

　　"In the 20 years since the implementation of the advertising law, we have accumulated some practical experience and formulated some practical normative measures. It is now necessary to make a summary, raise the norms into laws, and make targeted norms for new situations and new problems. " Liu Shuangzhou, deputy dean of the School of Law of the Central University of Finance and Economics, said.

　　Crack down on false advertisements in all directions

　　It was submitted for deliberation for the first time in August 2014, submitted for deliberation for the second time in December, and passed for the third time in April 2015. In less than one year, the revision of the advertising law quickly responded to the call of all sectors of society to severely crack down on advertising chaos according to law, and condensed the public’s consensus on increasing advertising supervision.

　　It is an urgent task for the new advertising law to curb and crack down on false advertisements. In this regard, the new law first clarifies the definition of false advertisements, and stipulates that advertisements will be regarded as false advertisements in five situations, such as goods or services do not exist, information such as product performance is inconsistent with the actual situation, fictitious proof materials are used, the effect of goods is fictitious, and consumers are deceived and misled by false content.

　　At the same time, the new law also increases the legal responsibility for publishing false advertisements, and stipulates that the administrative department for industry and commerce has the right to impose a fine of 3-5 times the advertising cost on advertisers. If the advertising cost cannot be calculated or is obviously low, a fine of 200,000-1 million yuan can be imposed. In addition, the new law also stipulates that those who violate the law for three times in two years will be fined 5-10 times the advertising cost, or 1-2 million yuan, and their business licenses can be revoked. This is obviously stricter than the current advertising law, which stipulates that the advertiser shall bear civil liability for publishing false advertisements according to law.

　　Should celebrities bear joint and several liability for endorsing false advertisements? There have been different debates in the society: some people think that stars only assume the role of "salesmen", do not understand the process of product production, and ask them to take responsibility for product quality, which is suspected of exceeding their authority; However, some people think that stars use the public’s trust to make them choose problematic goods and services, and producers, operators and spokespersons jointly commit infringement and should bear joint and several liability.

　　In this regard, the new advertising law clarifies the celebrity endorsement from the standpoint of safeguarding consumers’ rights and interests, stipulating that advertising spokespersons shall not recommend or prove their unused goods or services, and advertising spokespersons of false advertisements shall not speak for advertisements again within three years.

　　"False advertisements are very harmful to the society. The new advertising law clearly defines false advertisements, greatly strengthens legal responsibilities, enhances operability, and is conducive to further strengthening the governance of false advertisements." Yang Wu, deputy to the National People’s Congress and president of the All-China Patent Agents Association, said.

　　Set rules for internet advertising

　　"Everyone has a free advertising space." In April this year, an APP that made money by reading and sharing advertisers’ marketing articles was widely circulated among friends. "In 2014, the overall online advertising market in China exceeded 150 billion yuan, a year-on-year increase of 40%, of which mobile Internet advertising grew strongly." With the rapid development of Internet technology, the media advertising industry is accelerating the transformation and reform: the advertising revenue of TV media is basically flat, while the print media continues to decline, while the advertising of Internet and mobile Internet is growing at an average annual rate of over 30%.

　　The current advertising law obviously did not foresee such a rapid development trend of internet advertising, and the word "Internet" could not even be found in the law. The lack of rule of law led to the rapid decline of Internet advertising from the golden age. The most obvious features are spam messages and spam. Selling cars at low prices, promoting sales in shopping malls, and issuing invoices, all kinds of junk messages and emails that have nothing to do with themselves but have to be read have seriously affected people’s normal lives. Statistics show that in 2014, the number of spam messages in China reached 45.4 billion, of which advertising promotion accounted for 65%.

　　Obviously, the new advertising law cannot ignore this important change. There are special provisions in the new law that the provisions of this law shall apply to the use of the Internet for advertising activities. The use of the Internet to publish and send advertisements shall not affect the normal use of the network by users. At the same time, in response to spam and spam messages, the new law stipulates that no unit or individual may send advertisements by electronic information without consent. If an advertisement is sent by electronic message, the true identity and contact information of the sender must also be clearly stated, and the way to refuse to accept it should be provided. If telecom operators and Internet information service providers fail to stop advertisements knowing that they are illegal, the industrial and commercial departments will confiscate their illegal income, and if the circumstances are serious, they will stop related businesses according to law.

　　"The new advertising law has solved some problems existing in the current advertising law, solved some advertising chaos that has been strongly reflected by the public, and is more perfect, sound and reasonable at the institutional level. At the same time, it has standardized law enforcement behavior and is conducive to promoting administration according to law." Zhao Xudong, deputy dean of the School of Civil and Commercial Economic Law of China University of Political Science and Law, expressed the hope that the new advertising law can better regulate advertising activities, more effectively protect the legitimate rights and interests of the public and consumers, and promote the healthy development of the advertising industry. This is also the greatest expectation of the public for the new law. (Peng Bo)

　　Six months, 319 thousand pieces. This is the number of people’s messages responded to the "Leadership Message Board" of People’s Daily in the first half of 2022. Since the 18th National Congress of the Communist Party of China, more than 3 million mass opinions and suggestions have been answered on the "Leadership Message Board". A message board has become a communication platform for listening to people’s voices, understanding people’s difficulties, and absorbing people’s suggestions, which has contributed to solving more and more people’s concerns. This vividly explains the value of Chinese-style democracy "all for the people" and strongly demonstrates the unique advantages of people’s democracy in the whole process.

　　General Secretary of the Supreme Leader pointed out: "Democracy is not an ornament, not for decoration, but for solving problems that people need to solve." The whole process of people’s democracy development in China has a complete system and procedure, as well as a complete participation in practice, which avoids the disadvantages of making promises all over the sky during the election and being ignored after the election. It can be said that the whole process of people’s democracy has achieved the unity of process democracy and achievement democracy, procedural democracy and substantive democracy, direct democracy and indirect democracy, people’s democracy and national will. It is a full-chain, all-round and full-coverage democracy and the most extensive, authentic and effective socialist democracy.

　　Establishing a correct view of democracy and persisting, developing and innovating consistently is the first priority of developing democracy and the "master key" and "master switch" of realizing democracy. True democracy, good democracy, we must make the people the masters of the country. Democracy in China is people’s democracy, and people being masters of their own affairs is the essence and core of democracy in China. From the implementation of the people’s congress system to upholding and improving the multi-party cooperation and political consultation system led by the Communist Party of China (CPC); From consolidating and developing the broadest patriotic United front to implementing regional ethnic autonomy; From "small courtyard chamber" to "house forum" … … In China, all national systems are built around the people being the masters of the country, and the national governance system is built around the realization of the people being the masters of the country, forming a comprehensive, extensive and organically connected system of people being the masters of the country, and building diverse, smooth and orderly democratic channels. The people are the masters of the country, which is embodied concretely and realistically in the policies and measures of the party governing the country, in the work of the party and state organs in all aspects and at all levels, and in the work of realizing the people’s yearning for a better life. In a word, the whole process of people’s democracy in China is a democracy centered on people’s interests.

　　Democracy begins with the full expression of the people’s will and is implemented in the effective realization of the people’s will. The will of the people can only be expressed, but not realized, and it is not a true democracy. The whole process of people’s democracy covers economy, politics, culture, society, ecological civilization and other aspects. It is related to national development events, social governance difficulties, and people’s daily chores. It has the continuity in time, the integrity in content, the synergy in operation, and the extensiveness and continuity in people’s participation, so that all aspects of national political life and social life reflect the people’s wishes and hear their voices. The people conduct extensive consultations on major issues of reform, development and stability and issues concerning their own interests through various ways and means, such as discussion, internet and opinion polls, before making decisions and during their implementation; The National People’s Congress "opens the door to legislation" and the government "opens the door to ask questions", and more and more people’s opinions are transformed into major decisions of the party and the government; Ordinary people speak freely through the congresses of villagers, residents and owners, and promote the management of public affairs … … In China, people’s expectations, hopes and demands, from national policies to social governance, to people’s food, clothing, housing and transportation, have been said in some places, listened to, implemented and given feedback.

　　There is a rainbow cartoon on the wall of Gubei Citizen Center, Hongqiao Street, Changning District, Shanghai, which connects Hongqiao Street at one end and leads to the highest legislature at the other. As one of the first grass-roots legislative contact points established by the National People’s Congress Standing Committee (NPCSC) Law Committee, as of June this year, Hongqiao Street grass-roots legislative contact point has completed the consultation of 67 draft laws, covering more than 10,000 people, and submitted 1,363 legislative suggestions. This is a concrete manifestation of the strong vitality of democracy in China. The more socialism develops, the more democracy develops. Strive for a new journey, always adhere to the people-centered development thought, unswervingly promote people’s democracy throughout the process, and will surely achieve new development of democracy in the process of constantly promoting the all-round development of people and the common prosperity of all people, so that the tree of democracy will be deeply rooted and evergreen forever.
