Charging Infrastructure of Electric Vehicles in Hunan Province

Interim Measures for the Administration of Construction and Operation

Chapter I General Principles

　　the first In order to speed up the construction of electric vehicle charging infrastructure and standardize the construction and operation management of electric vehicle charging facilities in the province, these Interim Measures are formulated according to the spirit of Guiding Opinions of the General Office of the State Council on Accelerating the Construction of Electric Vehicle Charging Infrastructure (No.73 [2015] of the State Council).

　　the second The charging infrastructure of electric vehicles as mentioned in these Measures (hereinafter referred to as charging facilities) includes intelligent charging service platforms, centralized charging and replacing power stations and decentralized charging piles, which are mainly divided into four categories:

　　1. Self-use charging facilities. Refers to the self-use vehicle charging facilities built in fixed parking spaces owned by individuals or leased for a long time (more than one year).

　　2. Dedicated charging facilities. Refers to the special charging facilities for public service vehicles or units (employees) vehicles built in the exclusive parking lots (spaces) of government agencies and social organizations.

　　3. Public charging facilities. Refers to the public charging facilities for social vehicles built in independent plots, social public parking lots, public parking lots in residential quarters, parking lots equipped with commercial buildings, public road parking lots, gas stations, expressway service areas, airports and other areas within the planning.

　　4. Centralized charging station with independent land occupation. Refers to the charging infrastructure that is not combined with public parking lots and building parking lots, and occupies an independent area and meets the land use planning. A centralized charging station shall have no less than 3 charging piles, and the spacing between piles shall be no more than 10m.

　　Article Based on the principle of "meeting needs, saving resources, and being moderately ahead of schedule" and the requirements of "adapting measures to local conditions, helping each other quickly and economically", the implementation will be promoted as a whole after it is easy.

Chapter II Planning and Construction

　　CCTV News:The "big footprints" of fireworks in the sky at the opening ceremony of the Beijing 2008 Olympic Games are still impressive. As the general design of visual arts for the opening ceremony of the Winter Olympics, Cai Guoqiang once again partnered with Zhang Yimou to add luster to the opening ceremony with unique fireworks.

　　In an exclusive interview with a reporter from the General Station, he said that under the creative principle of "simplicity, safety and brilliance", the total amount of fireworks set off this time was less than 10% of that of the 2008 Olympic Games.

　　Outside the Bird’s Nest of the National Stadium, a few hundred meters of fireworks are ready. Cai Guoqiang and his team are busy here every day, making precise preparations for the fireworks display at the opening ceremony.

The animated films in the hot show have inherited the system of "deifying" pioneered by other films, and taken another solid step on the road of building "China Animation School" in the new century with rich narrative content and distinctive artistic characteristics. However, its narrative defects have exposed the universality of domestic animated films in adapting myths and legends in recent years. It is of great significance to explore this issue in depth to promote the benign development of "China Animation School".

The new list of gods: Yang Jian takes the myth story of Aquilaria sinensis saving the mother as the core, integrates the relevant plots of Romance of the Gods, and integrates myths and historical stories such as the Goddess of Wushan and the warlord of Zhou Youwang, focusing on the mental journey of Yang Jian and Aquilaria sinensis seeking for themselves and resisting power, which is exactly the same as the previous similar works such as Ne Zha Legend of Deification weakening the collective ethical narrative and strengthening the personal growth narrative, showing the narrative and values of the "China Animation School" and traditional animation works in the new century. However, just like the controversy caused by Ne Zha’s release, the excessive reconstruction of The List of New Gods: Yang Jian under the shell of "a new story" is also worth pondering.

The most interesting thing in the film is the "blackening" transformation of the celestial groups represented by Yuding real person and the four heavenly kings. In the traditional story of the Three Notre Dames, the Lotus Lantern bears the spirit of Yang Chan and Liu Yanchang’s guarding and rebelling against love. This story was transplanted into the film, and it was adapted into the spirit of dedication to protect the world, and it was sublimated from "small self" to "big self" in value. However, with the development of the plot, the traditional narrative of Lotus Lantern gradually disintegrated: Yang Chan, the Three Virgin, who tried her best to suppress the mysterious birds, was just a chess piece ruthlessly manipulated by Yuding real people; While talking about "the great righteousness of the world" and "the sentient beings in the three realms", Yuding real people used Yunhua, the mother of Yang Jian, and Yang Chan, the sister of Yang Jian, to achieve their political goals, and the original touching friendship between master and apprentice disappeared. Whether Yang Jian split Taoshan or Agarwood split Huashan, it was the deliberate operation of Yuding real interest groups, and the ethical connotation of the story itself was greatly weakened.

The story after the "new edition" has multiple explosive points, such as court tactics, blood relatives fighting, loyalty and injustice, which undoubtedly enhances the readability and commercialization of the film. In fact, in recent years, many animated films adapted from traditional myths and legends have such a tendency. Ne Zha strengthened Nezha’s "anti-tradition" color of "disobedience and unfilial", and Legend of Deification strengthened the hero’s lonely heroic color of resisting the collective will for personal value. This adaptation conforms to the trend of pursuing individuality in the current youth subculture and has gained many fans. However, the subversive reconstruction of the traditional story system and the ethical system behind it implies the danger of falling into the quagmire of value nihilism from myth nihilism.

The reason why these "new stories" can be established in narrative logic is that the system of China’s myths and legends is complex, which leaves enough space for the current reconstruction, but the ethical system behind it is complete and firm. Whether it is a personal narrative that praises love and exalts family ties, or a collective narrative of self-sacrifice and resistance to power, it contains the national spirit condensed by the Chinese nation in the long process of agricultural civilization evolution. This national spirit not only cherishes personal values, but also vigorously promotes family, family-centered collectivism values and community consciousness.

However, from Legend of Deification in The Big Fish Begonia to The New List of Gods: Yang Jian, this collectivism value and community consciousness have been gradually deconstructed in the artistic world of "New Stories". For example, the concept of "love is above everything else" in Big Fish Begonia and Legend of Deification’s concept of "individual is above the collective" clearly declared this tendency, while The New List of Gods: Yang Jian quietly hollowed out the core of social and ethical relations such as mentoring and friends through the blackening of Yuding real people, leaving only the trust and willfulness of the relationship between individuals and blood relatives, which undoubtedly fell into the pattern of individualism.

Animated films conform to the growth track of the younger generation, express the value appeal of young people, and also reflect the value confusion of young people. Domestic animated films with "new stories" are put into the "new wine" of youth culture with "old bottles", but the educational and guiding functions of film art as an important category of popular culture are ignored. Although traditional stories have their limitations of the times, there are also defects and misunderstandings in youth subculture. The significance of "new story compilation" is not only to endow the traditional narrative with new connotation of the times, but also to guide the audience to establish "new value" in the new era with "old stories". If we blindly obey and cater to the aesthetic preference of the market and abandon the responsibility and mission of socialist literature and art, the development of animated films will inevitably be mired in the quagmire of commercial reproduction.

Needless to say, with its exquisite artistic presentation and complicated narrative construction, The List of New Gods: Yang Jian has become the most eye-catching animated film this summer, and will certainly become one of the representative works of "China Animation School" in the new century. However, how the "China Animation School", which is characterized by the "new story compilation", establishes the value benchmark of the new era in the "new story compilation", organically combines the construction of the nationality of animated films with the modernization of the national spirit, and makes domestic animated films become an important participating force in the creative transformation and innovative development project of excellent traditional culture, which is still an urgent problem for China animators.

　　　　"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.

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.

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.

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!

Recently, fans of KUN, a new traffic star who debuted from Idol Trainee, made a mistake. The reason is that the number of Weibo fans in KUN has exceeded 7 million. He sent a Weibo saying, "How about dyeing black hair as welfare?" After Weibo was sent out, the netizen "@ I’m Chen Hongyu" forwarded it and said, "Why do some people on this planet think that dyeing their hair is a welfare for others? God XX is crazy. "

Although the netizen’s spit is not friendly enough, it is estimated that he did not expect that he would be so seriously bullied by fans in the future. Some fans searched for photos of this passerby and his school "civil aviation university of china", and they were crazy about @ civil aviation university of china. Even some fans have entered the extreme state of "scolding whoever they catch". For example, some netizens just commented on the netizen’s Weibo, and they were also insulted by fans. In the end, @ I’m Chen Hongyu, who couldn’t resist the fierce attack of fans, sent two Weibo apologies in succession, stressing that he meant no harm, just teasing, "Please forgive me, fans and friends".

The essence of rice circles: the collective possession of idols by fans

What is a rice circle? In fact, it is the abbreviation of fan circle and fan group. Fans of a certain star together to form a group is a rice circle. In this circle, those who have money contribute and those who have no money contribute, and everyone does his or her job. Some people are responsible for taking photos, retouching and distributing pictures, some people are responsible for video editing, some people are responsible for judging, some people are responsible for forwarding and data … Fans invest a lot of time, money and energy just for a common goal: to make their idols better and redder.

To understand the rice circle’s unrepentant dedication to idols, we must first start with the characteristics of idols. In any developed entertainment industry, people in the entertainment industry can be divided into two categories: those who eat by strength and those who eat by face value. We call the former an actor/singer, and the latter a star. In essence, the entertainment industry is a consumer market, artists are commodities, and fans are consumers.

For an actor, his commercial value lies in his acting skills and the quality of his works, such as Li Xuejian, WU GANG and Qin Hao. They don’t have many crazy fans. Their excellent acting skills guarantee the quality of film and television dramas, and producers, TV stations and audiences all recognize them. The general audience will generally not know more about them than the text of the film and TV series itself.

For idols, it is not the case. Idols have no works, or they are only works. Some idols have nothing but a pair of beautiful skins. Why does he get the love of so many people? Because idols belong to fans, all his popularity depends on their support. Fans buy his records, watch his movies, buy his endorsement products, forward his Weibo, control the negative rumors about him on the Internet, create traffic for idols and strive for more performance opportunities because idols give fans an illusion: my success depends on your support bit by bit, and you are honored with any glory that belongs to me; I belong to you, I was born to meet your needs.

In Japan and South Korea, where the entertainment industry is highly developed, actors/singers and idols have long been different occupations, and they each have a strict training system. Actors don’t need to maintain "personal design" because he speaks by works, but idols have the requirement of "personal design". His smiles and every move must satisfy the fantasy of fans. Sh? Sakurai, a member of Tian Tuanlan, a Japanese national, explained "What is an idol" and "Idol is a profession selling dreams", which is right.

Nine percent of the "occasional practice" returned to China and hundreds of fans ran to pick up the plane.

Therefore, the essence of rice circles is actually a brand-new idol-fan relationship, and the essence of this relationship is the collective possession of idols by fans; The essence of idols is "to provide fans with an imaginative intimacy". Some scholars further define idols as a "database that provides imaginary materials about intimate relationships". Based on the data in this database, fans can choose and customize the image of idols themselves. Some people are "girlfriend powder", some are "mother powder" and some are "sister powder". But no matter what kind of powder, idols have become the carrier of some kind of intimate relationship.

It is in this sense that the fan welfare given by idols has been given different connotations. To outsiders, it’s no big deal for an idol to take a selfie on Weibo, say "good night" and dye his black hair, but for fans who are in imaginary close relationship with the idol, it’s "welfare", what’s important is daily companionship, which is to please others and is no different from falling in love.

Crazy rice circles: how to polarize rice circles

The emergence and development of rice circle culture has indeed brought many positive effects to the entertainment industry. For example, it has changed the traditional star-making mode, given fans more power, and is more conducive to the iteration and update of idols in the entertainment industry. However, the KUN fan incident has also become a microcosm of the crazy rice circle. On social networks, we often see one after another cyber violence caused by fans of some idols.

Fans support idols out of love, of course. The question is why this love has repeatedly evolved into cyber violence against others.

This is related to the reception of rice circle information and the closing and homogenization of values. There is an "information stratosphere" effect here That is to say, when receiving information, the audience always pays attention to information that is consistent with their original ideas, attitudes and values, or that they need to care about. At the same time, they will actively reject or avoid information that is inconsistent with their own ideas or has nothing to do with themselves: the direction of information flow is similar to that of the stratosphere. For rice circles, the information they receive every day is all about the good things of idols, and they are very wary and exclusive of all kinds of negative news about idols. This has led to the so-called "blowing with closed eyes" phenomenon, which means that no matter what idols do or how they do, fans can praise the sky.

Over time, they fell into the "information cocoon room". The information that fans are exposed to every day seems endless, but in fact, they are trapped in an island that can only accommodate the praise of idols, and it is difficult to accept any heterogeneous information. This will not only lead to the narrowness of individuals, the loss of individual judgment, and the misunderstanding of the real environment, but also may lead to the polarization of views and the polarization of network groups. This is why many rice circles are like a hedgehog with fried hair, stabbing people everywhere. Where there are bad reviews about idols, they must think that someone is deliberately framing idols. They must act quickly to fight back, and a vast network of violence has happened.

Moreover, rice circles, as a kind of "group", also have some group characteristics. Gustave Le Bon, a French social psychologist, pointed out in Mob that once you join a group, individuals will become impulsive, reckless and extreme. The reason and mechanism of this earth-shaking change lies in that once an individual joins a group and takes action, first of all, he/she will feel unprecedented power, and the crowd has overwhelming power, and the individual will feel this power immediately after joining the group, which is completely absent when everyone exists in isolation; Secondly, the individual’s sense of responsibility disappears rapidly, because he/she will feel that his/her responsibility is dispersed to a large number of people, and it tends to be zero for him/her personally; Third, in a group, members’ knowledge level, reasoning ability and value orientation are very different. Because of the huge number and short time, it is completely impossible for members to have a rational debate. Only by conforming to the belief of the greatest common divisor of the crowd in knowledge level, thinking ability and value orientation can the group take action, and these beliefs of the greatest common divisor are inevitably simple and primitive.

Le Pen’s analysis of the disadvantages of groups is quite obvious in rice circles. Many rice circle fans are younger, generally under the age of 18. Their values are immature, their thoughts are not rational enough, and they can easily become reckless, impulsive and violent under the noise of the group, and they lack accurate prediction of the responsibility and consequences of their actions. This leads them not to solve conflicts calmly and rationally, but to join the group and become a violent member, trying to reverse the trend of public opinion by various extreme methods.

Rice circles are not original sin, but don’t forget the original intention.

As a profession, it is normal for idols to give up some personal privacy and accept public evaluation, because all these are the attributes of this profession itself. However, in the deformed rice circle culture, idols can only accept public praise, and no bad reviews can appear. Whoever gives bad reviews to idols must have ulterior motives. Another important reason for this cognitive dislocation is that fans always unconsciously bring the imaginary intimate relationship between him and his idol into the public sphere.

Fans treat idols as lovers and relatives, and set a set of strict code of conduct in the rice circle, such as not discussing any news that has not been officially announced, not accepting bundling and gossip, and not spreading photos of private trips. This kind of boxing love is understandable. The problem is that fans can abide by it as much as they like in the rice circle, but they are not qualified to ask other passers-by in the public sphere to abide by it. Idol is a lover in the eyes of fans, but in the eyes of passers-by, he is an ordinary entertainer, a gossip, a talk about capital and an anecdote. This is like your Xiong Haizi. You can be a treasure, but you can’t ask other people in society to be tolerant of him everywhere.

Paradoxically, fans think they love idols, and they do not hesitate to launch cyber violence in order to maintain the image of idols. As everyone knows, their actions are just smearing idols. After the fan incident in KUN, there was a lot of criticism on the Internet. Many passers-by said, "Now I have no desire to know anything about KUN". "Fans’ behavior, idols pay the bill", a common saying in rice circles, is still the unchanging truth that summarizes such incidents. It is not so easy to establish the goodwill of idols, but it can easily be defeated by the actions of fans. This is actually the risk of the idol profession. How much you rely on fans also means how likely you are to be bitten by fans. Idol will always be fettered by fans. Although it is easy to gain popularity, it must be ready to accept the consequences at any time.

The crazy behavior of some rice circles may make some people who have never been to idolize feel disgusted with the existence of rice circles, and think that rice circles are synonymous with irrationality, ignorance, brain damage and violence. In fact, there are many rational and sober fans in the rice circle. They like idols, but they just "sprout from the ground" in the rice circle and will not bring the rules of the rice circle into real life. We should criticize the madness of some rice circles, but we should not stigmatize the whole rice circle-otherwise, it is different from those irrational rice circles.

According to Yang Ling, a fan culture researcher, people think that bored and empty people will need idolize to fill themselves, but in fact, the role of idols is far from filling the vacancy, and he/she can inspire fans to find a better and more meaningful life. Yang Ling said: "I chased the stars myself. This experience prompted me to study for a PhD, and I began to pay attention to a brand-new research field. I published some research results, met many scholars in related fields at home and abroad, and even had the privilege of accepting an interview with Professor Henry Jenkins, a big cow of fan research. Idolize can be said to have changed my life. "

For many people, joining the rice circle and becoming a fan of an idol is because they have an imagination about "beauty" in the idol-"beauty" is a word that many fans use repeatedly when describing idols. Yang Ling explains "beauty" in this way: "People who have both" beauty "and" good "are extremely rare in real life. Fans have pinned their hopes for a more perfect and free utopia on people they think are’ beautiful’. In the final analysis, stars and idols are just intermediaries, and they let fans enter another transcendent world from the earth. What fans ultimately want is pleasure, recognition and a sense of belonging. "

Therefore, compared with "if it’s not my race, its heart will be different" and "fighting in the south and fighting in the north", don’t forget that "beauty" and "self-sprouting in circles" are the personal accomplishments that rice circles need urgently.

Xinhua News Agency, Beijing, June 6th Question: China COVID-19 Vaccine "Why"? —— Xinhua News Agency reporter interviewed Ceng Yixin, deputy director of the National Health and Wellness Commission.

Xinhua News Agency reporters Chen Fang and Chen Xiyuan

The COVID-19 epidemic, which has never happened in a century, has been delayed for more than one year. The epidemic has fluctuated repeatedly, and the virus has frequently mutated. The situation is still complicated and grim.

Coping with epidemic prevention and control is a major event related to human development and an urgent issue of global governance.

The number and speed of vaccine research and development in COVID-19 are among the highest in the world. Two inactivated vaccines have entered the WHO emergency use list, supplying more than 350 million doses to the world … eliminating the "immune gap" and making every effort to promote the life of the people in the world to return to "normalization". Behind the "China speed" of vaccines in COVID-19, the mission of a responsible big country is demonstrated.

What is the overall progress of vaccine research and development in COVID-19? What kind of international cooperation has been carried out? What are the results of vaccine research in the real world? Will there be a new vaccine in the next step? ….. On the 6th, Ceng Yixin, deputy director of the National Health and Wellness Commission and head of the vaccine research and development special class of the scientific research team of the State Council Joint Prevention and Control Mechanism, accepted an exclusive interview with Xinhua News Agency to respond to the public’s concerns.

Unprecedented research-21 COVID-19 vaccines entered the clinical trial stage.

Q: The sudden outbreak of COVID-19 has posed an unprecedented challenge to tackling the vaccine problem. What is the level of China? What’s the current progress?

A: We insist on early deployment and multi-routes. In February 2020, we set up a special class to deploy vaccine research and development. The speed and quantity of vaccine research and development in COVID-19 have always been in the first phalanx in the world.

Twenty-one COVID-19 vaccines have entered the clinical trial stage in China. At present, four vaccines have been approved for conditional marketing in China, three vaccines have been approved for emergency use in China, eight vaccines have been approved for phase III clinical trials abroad, and one mRNA vaccine has been approved by ethics abroad, thus achieving comprehensive coverage of the technical routes of inactivated vaccine, recombinant protein vaccine, adenovirus vector vaccine and nucleic acid vaccine in overseas clinical trials.

While the number of vaccine research and development ranks among the top in the world, the speed of research and development has also set a record. The COVID-19 vaccine research and development project took only 2 months from the start to the first clinical research in the world; It took only four months to carry out the emergency use of vaccines for the first time in China’s history; It took only five months to carry out the overseas phase III clinical trial of vaccine for the first time in Chinese history. It only takes 11 months to get the conditional listing.

Taking vaccines as a global public product-more than 350 million doses have been supplied to the world, and more than 90 countries and regions have been approved for marketing or emergency use.

Q: At the opening ceremony of the 73rd World Health Assembly, China solemnly promised to make vaccines a global public product. With the global epidemic raging, how can China meet both domestic and international demands when its own vaccine demand is huge? What kind of strength do we contribute to the global fight against epidemic?

A: The COVID-19 epidemic is the most serious global epidemic of infectious diseases in the past century. General Secretary of the Supreme Leader led the largest global humanitarian action in the history of New China, and put the concept of human health community into practice with practical actions.

China’s COVID-19 vaccine has been approved for marketing or emergency use in more than 90 countries and regions around the world, and two vaccines have been approved for inclusion in the WHO emergency use list.

Although the total number of vaccinations in China has exceeded 700 million doses, which is far ahead in the world, the proportion of vaccinations per 100 people is not ahead. In this case, according to the epidemic situation at home and abroad, we make overall consideration of domestic and international needs and rationally allocate vaccine supply. China’s COVID-19 vaccine has supplied more than 350 million doses abroad, including donations to more than 80 countries and exports to more than 40 countries. In October 2020, China announced its participation in COVID-19 Vaccine Implementation Plan (COVAX) and promised to supply 10 million doses of vaccine. On May 7, 2021, after the inactivated vaccine of Sinopharm Zhongsheng Beijing was included in the WHO emergency use list, on June 1, the first batch of COVAX vaccine supplied by the institute went offline.

China is actively engaged in international cooperation in the research, development, production and use of vaccines in COVID-19. In terms of research and development, some vaccine research and development units have cooperated with relevant institutions in more than 20 countries, including the United Arab Emirates, Brazil, Uzbekistan, the Philippines and Pakistan, to carry out phase III clinical trials. In terms of production, the stock solution produced by some enterprises has been shipped to Brazil, Indonesia, Egypt, United Arab Emirates, Pakistan, Malaysia and other countries, and overseas sub-packaging has been started.

China’s valuable anti-epidemic experience is to uphold the people first and life first, and always put people’s life and health first. In the face of the raging epidemic, no one can be immune. In order to make China contribution to the accessibility and affordability of vaccines in developing countries, and to fulfill the solemn promise of "providing more vaccines to the outside world as much as possible", China said so and did the same.

Real-world research shows that China vaccine has good protection.

Q: Vaccine is a sharp weapon to overcome the epidemic, and everyone is very concerned about the actual protective effect of vaccine. How safe and effective is the vaccine approved in China in the real world?

A: Because the epidemic situation abroad is still grim, it is not easy to accurately count the real-world protection rate, but there are two cases to introduce. The Ministry of Health of Chile once announced that as of May 16th, the country had been inoculated with about 13.25 million doses of inactivated Kexing vaccine. The results showed that after the second dose was inoculated for 14 days, the effective rate of preventing symptomatic infection was 65.3%, the effective rate of preventing hospitalization was 87%, the effective rate of preventing entry into intensive care unit was 90.3%, and the effective rate of preventing death caused by infection was 86%.

On June 1st, Kexing released the preliminary results of COVID-19 vaccine trial "S Plan" in Celana, Brazil. More than 90% of the 40,000 people in this city have been vaccinated. The results showed that although the epidemic situation in the surrounding areas was still serious, the number of deaths caused by Covid-19 infection in Serrana decreased by 95%, the number of symptomatic cases decreased by 80%, and the number of inpatients decreased by 86%. In addition, vaccination also plays an immune barrier protection role for unvaccinated children and adolescents.

Large-scale vaccination in China fully shows that the vaccine in China has good safety. According to statistics, the reported incidence of adverse reactions after more than 700 million doses of vaccination in China is 118.6/100,000 doses. Among them, general reactions accounted for 83%, and abnormal reactions accounted for 17%. The incidence of general reactions and abnormal reactions were lower than the average reported level of various vaccines routinely vaccinated in China in 2019.

Phase III clinical trials also show that the vaccine has good safety and effectiveness. On May 26th, the international medical journal Journal of American Medical Association published the results of phase III clinical trial of two inactivated vaccines developed by Sinopharm Zhongsheng, which was the first officially published phase III clinical trial of inactivated vaccine in COVID-19 in the world. The data showed that the protective efficacy of the two inactivated vaccines was 72.8% and 78.1% respectively.

Building the Great Wall of Immunization-It is estimated that at least 70% of the target population will be vaccinated before the end of the year.

Q: According to the WHO report, the COVID-19 epidemic has caused more than 3 million deaths worldwide, affecting more than 200 countries and regions. China is promoting the largest COVID-19 vaccination. What is the current progress? How far is it from building an immune barrier?

A: On March 24th, China officially launched the "daily newspaper" system for vaccination in COVID-19. Since May, vaccination has entered an "accelerated run". At present, the vaccination in COVID-19 has exceeded 700 million doses, and China vaccine has been recognized and accepted by more countries in the world. The recent local cases suggest that the situation of prevention and control is still grim, and we need your help to build the "Great Wall of Immunization" and reduce "vaccine hesitation".

In order to facilitate the people and promote the vaccination of the whole population, temporary inoculation points, mobile inoculation points and key places go hand in hand; The people in key industries, key units and key areas are expanding again and again in order to meet everyone’s needs as soon as possible.

In this "big test" of vaccination, medical staff have made outstanding contributions. The inoculation amount is more than 20 million doses a day, and it is more than 100 million doses in five days. Every link must be checked, and every code can’t be wrong. This is the hard work of the majority of medical staff. They are respectable and lovely! It is estimated that at least 70% of the target population will be vaccinated by the end of this year.

Q: What new research do we have on the impact of virus mutation on vaccines that people are concerned about? How is the emergency use of atomized inhalation COVID-19 vaccine progressing? Will the age of emergency use of vaccines be expanded again?

A: First, we actively promote the follow-up related research of COVID-19 vaccine, including real-world research and immune persistence research, so as to provide reference for further large-scale use of the vaccine.

Second, the current research shows that the existing vaccine can control the existing virus variation. However, we must take precautions. Under the situation that the virus is still spreading rapidly around the world, we must closely monitor the variation of the virus and do a good job in the research and development of vaccines for severe mutant strains in Covid-19 in advance.

Third, actively promote more vaccines to carry out phase III clinical trials, promote more vaccines to market, and form greater production capacity, with the ultimate goal of increasing vaccine supply.

Fourthly, nasal spray vaccine is also one of our earliest technical routes. At present, the relevant units are carrying out clinical trials of nasal spray and aerosol inhalation COVID-19 vaccine and collecting statistical analysis. After the data are basically complete, we will organize experts to demonstrate its safety and effectiveness in due course.

Fifthly, the population of vaccine users in COVID-19 in China has covered over 18 years old, and the age of vaccinators is over 100 years old. At present, experts have demonstrated the safety and effectiveness of the vaccine used by people aged 3 to 17, and will use it in this population as needed after approval by relevant state departments.

Sixthly, we also advocate that WHO can make timely adjustments to the rules of COVID-19’s entry into the emergency use list according to the actual situation of global epidemic prevention and control. For example, for animal experiments and phase I/II clinical trials, the effect is very good, and the production is in full compliance with GMP standards. Therefore, we should consider exempting phase III clinical trials and taking neutralizing antibodies as a substitute index, which can greatly increase the supply of vaccines.

The virus is our common enemy, and the whole world is a community of human destiny. One place is not safe, and nobody is safe. "Hello everyone is really good!" We must join hands in this protracted war against the epidemic.

General Secretary of the Supreme Leader pointed out that promoting the green development of agriculture is a profound revolution in the concept of agricultural development. In the implementation of rural revitalization strategy, we must consistently adhere to green development, be conscious in thought, firm in attitude, clear in policy and persistent in action, which is the key to determine whether we can successfully embark on a road of rural revitalization in Socialism with Chinese characteristics.

Deeply understand the revolutionary significance of promoting the green development of agriculture

Agricultural modernization is always the foundation of national modernization. Agricultural production is a special industry determined by both natural and economic laws. The green development of agriculture is based on respecting nature, aiming at coordinating economic, social and ecological benefits, relying on the use of various modern technologies, and actively engaging in the scientific and rational development and breeding process of sustainable development. Promoting the green development of agriculture is not only an economic change related to the adjustment of agricultural structure and production mode, but also a green revolution in behavior mode and consumption mode. We should deeply understand the revolutionary significance of promoting the green development of agriculture, adapt to the trend of industrial civilization to ecological civilization, promote the formation of a green development path of agriculture with China characteristics in the new era, and contribute China wisdom and China’s plan to the development of world agriculture.

It is necessary to deeply understand the seriousness of the problems facing the current agricultural development. In recent years, China’s agricultural modernization has made great achievements and paid a great price. Over-utilization of cultivated land and water resources, increased agricultural non-point source pollution, degradation of grassland and other ecosystems, agricultural development is facing two "tight curses" of resource conditions and ecological environment. It is urgent and urgent to change the concept of agricultural development and realize the green development of agriculture. Promoting the green development of agriculture is not only an important decision made by the central government to understand the profound changes in society, respect the laws of nature and conform to the people’s ardent expectations, but also the inherent needs of agriculture itself. By changing the mode of production, the excessive intensity of resource utilization will be reduced, the trend of increasing agricultural non-point source pollution will be slowed down, and agriculture will be promoted to the road of green development.

We should deeply understand the arduousness of promoting the green development of agriculture. At present, promoting the green development of agriculture has ushered in a great opportunity, but it also faces some deep-seated difficulties. At the conceptual level, some comrades have not really put the transformation of agricultural development mode on the important agenda for a long time in pursuit of the habitual thinking of output growth, thinking deeply, carefully planning and solidly promoting it. On the interest level, promoting the reform of agricultural development mode will inevitably profoundly adjust the interest relationship between different stakeholders, which will lead to some local and departmental business entities’ escape thoughts and fear of difficulties. At the working level, it will be an unprecedented grand undertaking to transform the existing system of technology, talents, policies and mechanisms for increasing production into a new system of quality and green, which requires determination, tenacity and innovation.

We should deeply understand the long-term nature of promoting the green development of agriculture. To promote the green development of agriculture, we must be prepared for a protracted war. It is necessary to scientifically judge the problem situation faced, organically combine long-term scientific planning with phased target planning, treat both the symptoms and root causes, slowly and steadily, and gradually advance in depth. Strive to sum up and popularize a number of models and technology integration in line with the green development of regional agriculture by 2020, establish and improve the working mechanism, institutional system and incentive and restraint mechanism of green development of agriculture, and initially form a green production mode and a green lifestyle of agriculture. After 10-15 years or even longer efforts, the concept of green development has been deeply rooted in the hearts of the people, the institutional system has been improved, and the green production mode and lifestyle have been fully formed.

We should deeply understand the systematicness of promoting the green development of agriculture. Promoting the green development of agriculture is a systematic project, involving all fields of agriculture and even economic and social development. This is not the adjustment and repair of a single system, but the innovation and construction of various institutional mechanisms; It is not the independent promotion of the agricultural field, but the coordinated and systematic promotion of various industries and levels in agriculture. We must plan the overall situation, mobilize the enthusiasm of all parties, analyze the key points in detail and act in concert. It is necessary to give full play to the decisive role of the market in allocating resources and the role of the government, and encourage producers, operators and consumers to participate in the green development of agriculture.

Focus on the strategy of rural revitalization and vigorously promote the green development of agriculture

The 19th National Congress of the Communist Party of China made a major decision to implement the rural revitalization strategy. The countryside is the main area of ecological environment, and ecology is the biggest development advantage of the countryside. Promoting the green development of agriculture is the proper meaning of high-quality development of agriculture and the objective need of rural revitalization. In 2017, the Central Office and the State Council issued the Opinions on Innovating System and Mechanism to Promote Agricultural Green Development, which made comprehensive and systematic arrangements for promoting agricultural green development at present and in the future. To implement the central government’s plan, we must focus on the revitalization of rural industries, effectively promote the changes in agricultural spatial layout, resource utilization mode and production management mode, and push rural industries onto a road of revitalization with China characteristics of spatial optimization, resource conservation, environmental friendliness and ecological stability.

Promote the change of development concept and lead agricultural production with green concept. We must resolutely implement the Opinions of the Central Office and the State Council, adhere to the development concept of green agriculture, and turn to green orientation from ideas to methods, from policy measures to work arrangements, from system design to scientific and technological research and development, from resource allocation to performance evaluation. Guided by the green concept and driven by reform and innovation, we will accelerate the formation of a joint effort and a good atmosphere to promote the green development of agriculture, and provide strong support for the construction of ecological civilization and beautiful China.

Promote the transformation of production methods and achieve a golden harvest in a green way. To promote the green development of agriculture, we should make overall plans to ensure supply, income and ecology. We should neither sacrifice ecology because of supply and income, nor let the supply of agricultural products and farmers’ income be affected because of ecology. It is necessary to change the past way of exchanging large quantities of water and fat drugs for high yield, increase the intensity of technology integration, demonstration and promotion, and personnel training, accelerate the popularization of a number of advanced and applicable green agricultural technologies in the field of agricultural production, promote the green production mode to take root, ensure the supply of grain and important agricultural products, and realize the sustainable development of agriculture.

Promote the transformation of industrial structure and use green industries to promote quality improvement and efficiency improvement. Guided by market demand, we should abandon the practice of simply pursuing output, give priority to increasing green and high-quality agricultural products, promote the transformation of industrial structure, realize the diversification, personalization, differentiation, quality and branding of products, and better meet the people’s consumption needs for safety, quality, nutrition and health. At the same time, it is necessary to develop various functions of agriculture, strengthen the construction of agricultural ecological infrastructure, restore the ecological landscape of agriculture and rural areas, enhance the ecological value, leisure value and cultural value of agriculture, promote the deep integration of agriculture with tourism, culture, health care and other industries, and promote agricultural efficiency, farmers’ income and rural greening.

Promote the reform of management system, guide new subjects to promote green development and become a common form of agriculture. At present, China’s agricultural production is still dominated by small-scale decentralized management, and the existence of a large number of small farmers is still our fundamental. The technology, capital and talents needed for the green development of agriculture are still relatively high for small farmers. We must promote the green transformation of the management system, develop various forms of moderate scale management, innovate the connection path, integrate the green development of agriculture into all aspects of agricultural production and management, and drive small farmers to enter the track of green development of agriculture.

Promote the reform of institutional system and promote green development with green system. General Secretary of the Supreme Leader emphasized that only by implementing the strictest system and the strictest rule of law can we provide a reliable guarantee for the construction of ecological civilization. It is necessary to comprehensively build an institutional system for agricultural green development, strengthen policy support such as interest compensation, cultivated land protection compensation, ecological compensation and financial incentives in major grain producing areas, speed up the establishment and improvement of a standard system for green agriculture, improve the legal and regulatory system for green agriculture, strive to build an institutional environment for green development with clear standards, effective incentives and strong constraints, implement the green development responsibilities of governments and departments at all levels, and let producers and consumers take the initiative to put ecological protection in an important position to stimulate the enthusiasm of the whole society for developing green agriculture.

Highlight the key points, grasp the key points, and continuously push forward the green development of agriculture.

To promote the green development of agriculture, we should not only make overall consideration and overall planning, but also highlight key points and have a clear aim. We must adhere to the problem orientation, focus on the main battlefield, make practical moves, fight hard, and push the green development of agriculture deeper and deeper. In particular, it is necessary to summarize and refine a number of technical measures, production models and management methods that can be replicated, popularized and operated, and play a leading role in demonstration and promotion.

Improve ideological understanding. All localities and departments should fully understand the importance and urgency of promoting the green development of agriculture, take the initiative, act positively, plan carefully and push pragmatically. We must conscientiously implement the "Opinions" of the Central Office and the State Council, identify problems and difficulties in light of specific conditions, and innovate ways and means to ensure that all policies and measures are implemented.

Optimize the functional layout. Adhere to planning first, rationally distinguish agricultural space, urban space and ecological space, further optimize the regional distribution of agricultural productivity, standardize the spatial order of agricultural development, and promote the formation of an agricultural development pattern that matches the carrying capacity of resources and environment and is coordinated with production and life ecology. It is necessary to establish an important agricultural resource ledger system and find out the base of agricultural resources. Construction of digital agriculture management system in the sky and land, using the integrated observation technology of space remote sensing, aerial remote sensing and ground Internet of Things to realize the dynamic monitoring and precise management of resources and environment, and provide support for constantly and dynamically adjusting the main functions and spatial layout of agriculture.

Promote scientific and technological innovation. It is necessary to vigorously support green agriculture-oriented scientific research and development promotion, organize and implement relevant major scientific and technological projects and major projects, further improve the collaborative research mechanism of various innovative subjects, attract social capital and resources to participate in scientific and technological innovation in agricultural green development, obtain a number of breakthrough scientific research achievements as soon as possible in key links that restrict agricultural green development, integrate and assemble a number of technical models for green production, and increase demonstration and promotion efforts. At the same time, it is necessary to strengthen the construction of agricultural science and technology talents in the field of resource and environmental protection, and provide a solid talent guarantee for the green development of agriculture.

Improve the industrial chain. It is necessary to improve the processing and circulation system of green agricultural products, close agricultural production and market consumption, and promote farmers’ sustained income increase. It is necessary to vigorously strengthen the circulation and marketing of green agricultural products, promote the construction of the origin market that is compatible with the green development of agriculture, strengthen the construction of the information service function of the origin market, improve the circulation efficiency, reduce operating costs, and help solve the problems that agricultural products are difficult to sell, unable to sell and unable to sell at a higher price. We should vigorously develop green processing, optimize industrial layout, promote the coordinated development of primary processing, intensive processing and comprehensive utilization of by-products of agricultural products, and form a circular development model of "resources-processing-products-resources".

Protect agricultural resources and environment. In terms of resource protection, the focus is on protecting cultivated land and water resources. Vigorously develop water-saving agriculture; We will further promote the action of protecting and improving the quality of cultivated land, expand the area of remediation of cultivated land contaminated by heavy metals, and carry out pilot projects of fallow farmland rotation to ensure the quantity and quality of cultivated land. At the same time, we should do a good job in the implementation of the grassland ecological compensation policy, promote the prohibition of grazing and the balance between grass and livestock, and implement the total management of marine fishery resources and the "double control" system for fishing boats. In terms of environmental protection, it is necessary to strengthen input quality control and waste treatment, promote the reduction and efficiency of chemical fertilizers and pesticides through precise fertilization, organic fertilizer substitution, unified prevention and control, and green prevention and control, and promote the resource utilization of crop straw, livestock manure and agricultural film.(Deputy Secretary and Deputy Minister of the Party Group of the Ministry of Agriculture Yu Xinrong)

China’s sustained economic recovery is increasing.

The policy of expanding domestic demand is intensively introduced, and online and offline consumption is active.

Since the beginning of this year, from the central government to the local government, the policy of expanding domestic demand has been intensively introduced, and the "popularity" in the consumption field has become more and more prosperous. Experts said that the offline consumer passenger flow has increased significantly, and online logistics orders have accelerated.

"Popularity" is an important perspective to observe the offline consumption fever. According to the analysis of people flow data by the National Information Center, since the beginning of this year, the consumption of offline residents in China has become more active. The heat index of people flow in offline business districts increased by 9.9% in the first quarter compared with the same period of last year, including an increase of 17.7% in March. Regionally, in March, the heat index of 31 provinces all achieved positive growth, with Guizhou, Tianjin, Anhui, Henan and Hainan provinces having the fastest growth rates.

In Guizhou, the "Village Super" and "Village BA" which were popular all over the network last year ushered in the opening season of the new year. In March, only Rongjiang and Taijiang counties attracted nearly one million tourists, driving the comprehensive tourism income to exceed one billion yuan.
