Chinese scientific research team found a new way to improve the performance of all-perovskite laminated solar cells

  Xinhua News Agency, Wuhan, November 12 (Reporter Hou Wenkun) After long-term research, Professor Ke Weijun and Professor Fang Guo from the School of Physical Science and Technology of Wuhan University have made new progress in exploring the performance improvement of all-perovskite laminated solar cells, and creatively put forward the integrated doping strategy of aspartic acid hydrochloride, which effectively improved the efficiency and stability of narrow-band gap perovskite subcells and found new ways to further improve the battery performance. Related research results were recently published in the journal Nature.

  According to reports, the new metal halide perovskite has the advantages of simple preparation process, high defect tolerance, high absorption coefficient and long carrier diffusion length, which has attracted much attention in the field of optoelectronic devices and is considered as one of the next generation photovoltaic materials with great prospects in the industry.

  Ke Weijun, one of the authors of the paper and a professor at the School of Physical Science and Technology of Wuhan University, said that in practical application, the all-perovskite laminated solar cell is composed of a broad-band gap perovskite subcell at the top and a narrow-band gap perovskite subcell at the bottom, and the narrow-band gap perovskite subcell that is not excellent enough is one of the stumbling blocks for its commercial application in the future.

  To this end, the research team introduced aspartic acid hydrochloride into the hole transport layer, perovskite light absorption layer and upper interface layer at the bottom of all perovskite laminated solar cells, and developed an integrated doping strategy with the same molecular treatment, which greatly improved the quality of perovskite thin films. In addition to coordinating with perovskite precursors, aspartic acid hydrochloride molecules also have strong intermolecular hydrogen bonds, so aspartic acid hydrochloride enriched at the upper and lower interfaces of perovskite acts as a molecular lock between the interface of perovskite layer and transport layer, further improving the performance and stability of perovskite materials.

  In addition, how to inhibit the spontaneous oxidation of unstable divalent tin metal ions in narrow-gap perovskite subcells is also one of the pain points in the industry. The results show that aspartic acid hydrochloride can effectively inhibit the oxidation of divalent tin ions and reduce harmful tetravalent tin impurities. Moreover, the introduction of aspartic acid hydrochloride can also passivate the defects of perovskite materials, adjust Fermi level and inhibit harmful ion migration, thus enhancing the performance and stability of devices.

  Ke Weijun said that the research shows that this simple integrated doping strategy can achieve multiple functions at one stroke and improve the steady-state efficiency of narrow-band perovskite subcells to 27.62%, which provides a new way to improve the performance of all-perovskite stacked solar cells.

Mermaid sadism! What’s the story of Stephen Chow’s The Mermaid?

    Special feature of 1905 film network On January 31st, The Mermaid, which will be released on the first day of the New Year’s Day, held a conference of "Fish, Water and Acacia" in Beijing. Director Stephen Chow made a collective appearance with the mighty "Mermaid Family" and released a trailer of the final version for 1 minute and 40 seconds.

    This highly anticipated film has maintained a mystery so far, and has always adopted the hunger marketing route, without any screening and media watching activities in advance. It is really hard to say whether Master Xing is too confident or too unsure about the quality of this film.

    We can only get a glimpse of several groups of film materials exposed at present.


1. This movie is very Stephen Chow.

Stephen Chow is not only the king of comedy of the performing world, but also the film he directed is unique. Starting from "Demon Journey to the West", he no longer arranged a place for himself in the film, but hid behind the monitor as a director.

Inner OS: What the hell is it? …

    The first time we heard that there was no Stephen Chow in a Stephen Chow movie, we felt a little sorry in our hearts. However, when we saw The Demon on a Journey to the West, we were surprised to see the familiar shadow of cynicism in the article, Bo Huang, Show Lo and even Shu Qi’s role.

    After a lapse of three years, there will be no guest appearance of Master Xing in The Mermaid, but through the director’s special feature exposed by the film, it can be found that his director’s way is to completely instill his performance into the actors, even at the expense of repeatedly demonstrating in person, in order to accurately meet his requirements.

Demonstrate and guide the actors to perform in person.

    So, even if Master Xing doesn’t appear in the movie, we don’t have to worry. "Mermaid" is definitely a film that inherits Stephen Chow’s strong personal style. There are all kinds of nonsense, cold humor, man show and madness in it, and every one is guaranteed.

2, the character has a big bottom and an N angle, which is related to mermaid sadism

    There are quite a few familiar faces in this movie. From the trailer currently exposed, we see Deng Chao, Show Lo, Yuqi Zhang, Jelly Lin, Li Shangzheng, Lu Zhengyu, Yang Neng, Ke Bai, Kong Lianshun, Wu Yifan, Wen Jian, Zhang Mei ‘e, etc., and all the immortals show their magical powers — — Of course, most of them are "dead walk-on".

For example, this:

Yang Neng, the "Pork Guy" in shaolin soccer, turned into the curator of the World Museum of Rare Animals in The Mermaid, and personally performed it for a group of tourists — — "Our ancestors were all fish."

There are also two police comrades who were exposed in the first preview, whose painting is "super good" and their understanding ability is "first-class", which were played by Tang Priest’s article and Friar Sand Li Shangzheng in "Demon Journey to the West" respectively.

Even Wu Yifan, a guest star, got a glimpse in the final trailer — — Look at the dress, you should be a rich second generation.

However, there is a role that has not been revealed so far, and that is "Master" Tsui Hark! At the press conference held yesterday, not only the "Mermaid Family" was all out, but also an old friend of Xingye, Tsui Hark, was invited, and he was revealed to have a guest performance in The Mermaid. "There are more than one line."

Master Xing also said with a smile: "Tsui Hark’s acting skills are very good. In fact, the director who can act best, I think one is Director Xu and the other is me. There is nothing to say about acting skills."

Two "old urchins" were funny at the press conference.

Of course, the most important roles in the film are the four donkey kong — — Octopus, mermaid, sea urchin and … … Lettuce?

Deng Chao: The hero of the film is a wealthy real estate developer and local tyrant. In Stephen Chow’s words, this character is a baby at heart, and his beard is his disguise. He wants to pretend to be a mercenary adult. Deng Chao himself explained it in Deng Shiying at the press conference as — — The beard is a ghost, and the beard is an angel.

Angel’s affection

Ghost’s evil (it should be evil … Xueba’s English is not flattering.

Jelly Lin: The mermaid, the heroine of the film, was forced to live in a wrecked ship because of the destruction of the sea and ecology by human beings. Deng Chao, who entered human society in disguise and used love to influence the development of marine resources, didn’t expect that he actually fell in love with him.

A tearful French kiss

Show Lo: Playing octopus is also a marine creature (nonsense). He has always loved the mermaid. When he found that "the person I love has a lover", he was very sad and tried to kill his rival with his tentacles. With eight giant tentacles, he can be regarded as the main fighting force of the mermaid gang.

Yuqi Zhang: Playing Deng Chao’s ex-girlfriend. Not only does she look like an overbearing female silver, but she is also the villain in the film — — The kind that is completely bad. She herself summed up this role as a "synthesis of violence and aesthetics" — — I am beautiful, but I am not gentle.

Mysterious mermaid: In the last fierce battle of the final preview, the amazing mermaid tail on the trailer and poster appeared again. Compared with Lin Yun’s small tail, this fishtail with colorful light has a powerful ability. When flapping the sea, it is "the four seas churn and the five continents shake and thunder". Judging from the expressions of fear on the faces of mermaid and octopus, adult fish should be the villain in the film. Yuqi Zhang, Lenovo’s villain, had a strange look at the little mermaid in the preview … … Murphy, Deng Chao breath even made two mermaid girlfriend? (This doesn’t seem to be the point … …

But if you zoom in carefully, the mermaid’s upper body seems to be a long-haired man in a white shirt, which is a bit similar to Yang Neng’s image.

How big is Master Xing’s brain hole? The answer can only be revealed after the film is released.

3. The main line of the story is positive energy

If you think this is a story that he loves her, she loves him, he loves her and doesn’t love her, and she loves him and doesn’t love him, then you are too young (fu) and childish (qian). You told us at the very beginning of the trailer that this is a tall environmental propaganda film!

Mermaids and humans should have lived in peace. Who knows, the more they progress, the more violent they become … …

Xuan Shao, played by Deng Chao, was originally a mercenary businessman. The development of real estate involved reclamation projects, which threatened the ethnic groups living in the sea. Jelly Lin’s mermaid Sam was sent to stop her. She turned into a human being, and fell in love with Xuan Shao in the process of fighting, and finally succeeded in stopping the whole project and protecting her home.

From this stills, we can also see that mermaids are covered with all kinds of rubbish and waste in the sea.

At the end of the trailer, it also echoed the theme:

If your life is only the last minute, if there is not even a drop of clean water and a breath of clean air on the earth, what do you want to do most?

In addition, we also saw a very familiar line in the previous trailer:

Isn’t this just a salted fish?


If you don’t have a dream, what’s the difference between being a man and salted fish?

It’s a tribute to the previous work.

The distance and measurement method between kindergartens and entertainment places and Internet service business places shall be specified by the provincial administrative department of culture and tourism in combination with the actual situation.

  Before the implementation of the Law on the Protection of Minors in People’s Republic of China (PRC), entertainment places and Internet service places have been set up around kindergartens. When the examination and approval authorities handle the renewal or change of business licenses, they should strictly follow the relevant laws and regulations, and earnestly implement the legal requirements that entertainment places and Internet service places should not be set up around kindergartens.

  Expert interpretation

  Yong Yang, a researcher at the Institute of Intellectual Property Law and Policy, East China University of Political Science and Law:The country has also further reformed and opened up to the outside world, giving enterprises more independent rights.At the same time, it is also considered that creating a better business environment and giving foreign investors a national investment treatment will still play a role in promoting and promoting the entire entertainment market. Through the opening up of foreign capital, the market activity will be further improved, which will enrich the spiritual and cultural life of ordinary people and bring a good impetus and prosperity.

  In the adjustment that entertainment places and Internet service business places are not allowed around schools and kindergartens, the Notice points out that the distance and measurement method between schools, kindergartens and business places shall be made by the provincial cultural and tourism administrative departments in light of the actual situation. Researcher Yong Yang also gave a related explanation.

  Researcher, Institute of Intellectual Property Law and Policy, East China University of Political Science and Law, ShanghaiYong Yang:Every city has a different volume, including Xuhui District in Shanghai, where there are 99 schools in more than 50 square kilometers. I think the interpretation of "periphery" should be given to the local cultural and tourism bureau according to the actual situation, which should not only ensure the prosperity of the market, but also maintain the legitimate rights and interests of the original enterprises, and at the same time effectively protect the rights and interests related to minors.

More than 7.6 million vehicles are rare! The largest recall of your car in domestic automobile history may also be included.

  CCTV News:In September, several major auto companies, such as Volkswagen and General Motors, successively announced the recall of some products.Within half a month, the total number of cars recalled by several major car companies reached more than 7.6 million, which is considered to be the largest number of car recalls in a short period of time.

  On September 14, AQSIQ announced that Volkswagen includesImported Volkswagen, FAW-Volkswagen, SAIC Volkswagen recall partImported Volkswagen, Audi, Seat, SkodaBrand and domestic Volkswagen and Audi brands, totaling more than 4.86 million vehicles.

  On September 15, GM included imports.Saab and OpelBrand, as well as domesticChevrolet and BuickBrand, announced a total recall of nearly 2.53 million cars.

  On September 25th, Guangqi Honda recalled some domestic products.Accord, Fit, FengfanWaiting for cars, totaling more than 245,000.

  The airbags produced by Takada Corporation of Japan are unsafe.

  It is understood that such a huge number of recalls point to a Japanese supplier — — Takada company, because the airbag it is equipped with for the automobile factory is not safe.

  It is understood that the reasons for the recall of Volkswagen, GM and Guangqi Honda include: the front airbag of the driver’s seat or the co-driver’s seat of some vehicles is equipped with an ammonium nitrate gas generator without desiccant produced by Takada Company. When the airbag is deployed, these gas generators may be abnormally damaged, causing debris to fly out, hurting people in the car, which poses a safety hazard. Several major car companies have said that they will replace airbags for vehicles within the recall range free of charge to eliminate potential safety hazards.

  Changan Ford, BMW Brilliance and many other car companies have previously announced the recall of some vehicles. The Takada airbag incident was in China.It involves more than 30 vehicle companies, involving about 20 million vehicles..

  Expert: the problem airbag is like a "throat cutter"

  Problem airbags have potential safety hazards, which may hurt people inside the car. What is going on? The authoritative third-party automobile safety inspection agency in China — — The chief expert of China Automotive Technology Research Center made an interpretation.

  In the test, the broken metal is ejected from the inferior airbag, just like a throat cutter, which directly stabs the dummy’s face and neck. The expert brought an airbag installed at the steering wheel to demonstrate on the spot: "The airbag is folded in the steering wheel. When the vehicle collides, the ignition device quickly ignites the combustion improver in the gas generator, and the energy released by the combustion improver quickly passes through the dense exhaust holes on the gas generator, so that the airbag expands and expands immediately."

  Experts pointed out that the gas generator of Takada airbag is filled with unstable ammonium nitrate combustion improver. Under the condition of high temperature and high humidity, the medium of ammonium nitrate has changed from flake to powder. Therefore, in the process of explosion, a larger explosion equivalent is produced, which causes the shell of the gas generator to rupture.

  Experts pointed out that when a vehicle collides, the airbag must be filled and deployed quickly in a short time, and its deployment speed is about 300 kilometers per hour. With such a fast speed, we must strictly ensure the safety of personnel.

  First, the airbag must be matched with the seat belt.

  Second, it is forbidden to put some ornaments, perfume bottles and so on in the area where the airbag is deployed.

  The airbags produced by Takada Corporation of Japan have caused many casualties around the world. Takada Corporation paid huge fines and compensation for this, and the company also filed for bankruptcy protection in June this year.

  Since 2008, after the first fatal accident occurred in airbags produced by Takada Company of Japan, by the end of February 2017, nearly 200 people had been killed or injured.

  In 2014, Takada Airbag began to launch a global large-scale recall.

  In January, 2017, Takada admitted that the hidden airbag would be fatal for 15 years, and agreed to pay a fine of $25 million, plus $125 million in compensation for the victims’ families and $850 million to pay the recall cost of the automobile manufacturer.

  As of May 2017, 19 automobile manufacturers, including Honda, Toyota, Nissan, BMW, Mercedes-Benz and Tesla, have recalled up to 120 million vehicles in the global market due to safety hazards of Takada airbags.

  In June 2017, Takada filed for bankruptcy protection.

  Expert: more attention should be paid to safety in parts concentration.

  China Automobile Industry Association pointed out that globalization has accelerated the monopoly trend of large-scale parts enterprises, which has both advantages and disadvantages. Large-scale parts enterprises will strengthen research and development, and drive or assist vehicle enterprises to promote technological progress. The disadvantage is that once the parts are too concentrated and there is a safety problem, it will have an impact on the global automobile industry.

[China Today] Marathon is not easy. What are the hidden worries behind the "war of words"

— — Issue 30 & mdash; —

On November 18th, He Yinli of China missed the championship in the Suzhou Marathon.

Because netizens questioned the setting of competition links, it triggered a network "war of words".

Why use it"You"?

Because in recent years, the marathon "war of words" has happened every year!

What are the "war of words" triggered by these marathons that you still remember?

Marathon was originally a place name in Greece. Because of a war, it has become a very popular long-distance running event in the modern world. Let’s take a look at the marathon that was played "bad" in those years.

Event: A marathon paralyzed a city.

Time: 2015 Location: Haikou City

The 2015 Haikou R&F Marathon attracted more than 7,000 participants (photo by Huang Yibing)

The 2015 R&F Haikou Marathon was held in Wanlv Park, Haikou City from 8: 00 to 14: 00 on Sunday, January 11th.

The race was not over yet. At about 12 o’clock that day, a report on Hainan Daily’s official WeChat "Haikou Today, A Marathon Paralyzes a City" pushed the marathon to the forefront.

The article quoted various "fancy spits" of Haikou citizens, which were reprinted by People’s Daily and China Youth Daily.

Can an enterprise buy a city’s transportation if it has money?

The question thrown by the article aroused great enthusiasm of netizens, and there was a wide-ranging debate on whether the city needed to hold a marathon and whether the citizens needed a marathon.

According to Xinhua News Agency, the Haikou Municipal Government finally admitted that there was a shortage of work, and the incident gradually subsided.

The reporter found that 2015 is not simple, and it can be called the "first year" of China Marathon.

Because in this year, the marathon officially began to be commercialized: since 2015, the Chinese Athletics Association has completely cancelled the approval of marathon events in accordance with the requirements of decentralization.

According to the statistics of China Athletics Association, in 2010, there were 13 marathon events registered nationwide, and in 2015, it reached 134.

On October 18, 2015, on this day alone, 27 marathon road races were held simultaneously in the country.

This year, the marathon has covered four municipalities directly under the central government and 79 cities in 23 provinces and autonomous regions. For the first time, the total number of people participating in the event exceeded one million, reaching 1.5 million.

Event: Sudden death of "substitute runner"

Time: 2016 Location: Xiamen

18,000 contestants from 28 countries and regions participated in the competition. (Image from Xiamen Net)

At 8: 00 am on December 10, 2016, the 2016 Xiamen (Haicang) International Half Marathon started.

A scene that shocked the audience appeared near the finish line: two players fell to the ground nearby and died after being rescued.

Four days later, netizens were shocked again: one of the victims was "resurrected"!

Because the organizing Committee issued a notice saying that one of the contestants who died suddenly was a "runner". On the same day, Wu Ming, the head of the office of the Organizing Committee of Xiamen International Marathon, announced in an interview with the media that there were still 30 contestants cheating, 28 of whom were "runners".

The sudden death has just triggered netizens’ doubts about the enthusiasm of the whole people for horse racing in that year, but there is a more outrageous scene in the "runner": in the 2016 Shenzhen Marathon, two of the top ten women’s team winners actually had Adam’s apple and were verified as men.

According to statistics, between 2015 and 2017, 14 people died unexpectedly while participating in domestic marathon events, and sudden death near the finish line accounted for 80%.

The physical quality, moral quality, fairness and openness of the participants have aroused the enduring concern of netizens about the marathon: the marathon is not what you want to run, you can run if you want to run!

Event: The organizer owes the bonus.

Time: 2017 Location: Jilin

In October 2017, Jilin Marathon participants Kong Jie and Mou Zhenhua voiced through the media that their bonuses were unpaid for four months.

According to the official website of Jilin Marathon, Kong Jie, a full-time female athlete, was ranked fifth in China at that time, ranking eighth in total; Mou Zhenhua, who was selected by the men in the whole process, was ranked third among domestic players and eighth in total. The results of the competition are true and effective.

In fact, the arrears of marathon runners’ bonuses have long existed.

The 2015 Linyi Marathon caused social concern due to the arrears of bonuses for African athletes. It was not until April 30, 2016 that all of them were distributed, and the half-year-old Linyi Marathon "unpaid wages" storm came to an end.

At the 2017 China Marathon Annual Meeting, documents such as "2017 China Marathon Annual Work Report" and "2017 China Marathon Big Data Analysis Report" issued by China Athletics Association showed that:

China hosted 1102 events in 2017.

The number of marathons increased to 4.98 million, and the number of marathons per 10,000 people was 4.27.

The marathon covers 234 cities in 31 provinces, autonomous regions and municipalities, including Tibet, with an industrial scale of 70 billion.

With the intervention of relevant departments in Jiangsu Province, the controversy caused by the Suzhou Marathon in 2018 gradually cooled down.

Overseas network published a commentator’s article saying that the marathon with tens of thousands of people participating at every turn is not just a long-distance running, it is the "touchstone" of the city’s comprehensive governance capacity. For the China Marathon, which has just started, it is especially necessary for practitioners and event organizers to take care of its growth with professional management and operation.

So, what kind of image will the marathon appear in the public eye next time?

Run, China! National fitness is on the road

  Create a "15-minute fitness circle" around the people and promote the free or low-cost opening of public sports facilities … … Not long ago, the Healthy China Action (2019— "2030)" has put forward a series of bright and hard indicators for the national fitness action, and has become a "construction drawing" for promoting the construction of a healthy China.

  On the occasion of "National Fitness Day" on August 8, this heavy action plan provides guidance and suggestions for people’s scientific fitness. From the guidance of government planning to the extensive participation of the whole people, the diversified fitness craze has risen everywhere, and the enthusiasm and creativity of hundreds of millions of people are pushing the health concept from "treating diseases as the center" to "people’s health as the center".

  Let "where to keep fit" become "keep fit around"

  "Where is the fitness going?" It used to be a problem for many people.

  Ma Mingyu, a citizen of Changchun, Jilin Province, is an aerobics enthusiast. However, the Yitong River, which is covered with black water and overgrown with weeds, has kept him away from the gym for a long time.

  In recent years, after water treatment and the construction of leisure fitness venues, riverside parks have sprung up and fitness trails along the river have gradually spread. Every evening, many citizens walk briskly along the Yitong River trail. The river is cool, the breeze is blowing gently, and the willow branches are swaying, which makes people feel carefree.

  "Thanks to the government for creating ‘ 15-minute fitness circle ’ We can exercise in the scenery now when we leave home. " Ma Mingyu said.

  The rise of national fitness is inseparable from the popularity of the "15-minute fitness circle".

  In the Healthy China Action Document, a set of data clearly describes the goal of a healthy China — — By 2022 and 2030, the opening rate of school sports venues and facilities will exceed 70% and 90%; The per capita sports ground area is 1.9 square meters and above and 2.3 square meters and above respectively.

  Nowadays, "fitness is around" has become a hot word in the circle of friends. "People’s awareness of fitness has increased, from the past ‘ Want me to practice ’ Up to now ‘ I want to practice ’ People’s physical health has generally improved, and the national fitness facilities and morning and evening training sites all over urban and rural areas, as well as the surging fitness boom everywhere, have become a beautiful landscape. " Zhang Ruilin, director of Jilin Provincial Sports Bureau, said.

  Exercise prescription makes health data "beautiful"

  Knocking on the keyboard with your shoulders, crossing your legs to see the materials, hunching over and eating takeout, unconsciously changed the cubicle office workers; Brush Tik Tok, play "mobile games" and see friends circle. Electronic products have made many people "low-headed".

  The data of the survey results of national fitness activities are not very good-looking: the proportion of urban and rural residents who regularly participate in physical exercise in China is 33.9%, of which the regular exercise rate of residents aged 20 to 69 is only 14.7%, and the regular exercise rate of adults is at a low level. Lack of physical activity has become an important reason for the occurrence of various chronic diseases.

  At present, although there are more and more "fitness coffee" dressed in short clothes, the damage caused by improper exercise is quietly eroding people’s fitness enthusiasm.

  Health China Action Document points out that individuals should master sports skills and exercise scientifically to avoid sports risks.

  Zheng Jiang, director of the Sports Medicine Clinic of the Red Cross Hospital in Xi ‘an, Shaanxi Province, said that the key to upgrading the concept of "to exercise" is to improve the public’s scientific exercise literacy, establish the concept of "exercise is a good doctor", and formulate individualized exercise prescriptions according to different ages, lifestyles and exercise abilities. By guiding people to exercise scientifically and reasonably and appropriately, we can bridge the key bridge between fitness and health.

  How to make people’s health data "beautiful"? Zheng Jiang suggested that in order to promote the formation of a "combination of sports and medicine" disease management and health service model, we should first strengthen the establishment of sports medical professional institutions and establish a number of sports prescription clinics through existing medical resources. Train sports medical professionals, improve their ability to evaluate sports risk and sports ability, and formulate individualized sports prescriptions.

  It is understood that the State Sports General Administration, the Chinese Sports Science Society and Beijing Sport University have done a lot of work in the construction and promotion of sports prescriptions. According to Wang Zhengzhen, a professor at Beijing Sport University, there have been 12 sessions of training for sports prescribers, and good results have been achieved.

  Billions of new fitness kinetic energy release more health dividends.

  Yoga, dance, boxing, barbell … … With the change of health concept and the upgrading of fitness consumption, the fitness market is developing rapidly, and "internet plus Fitness" is becoming more and more popular. What are the new "ways to play" and what shortcomings need to be made up for the national fitness that runs towards a better life?

  Focusing on the goals to be achieved by 2022 and 2030 proposed by the Healthy China Action, Wang Zhengzhen pointed out that the Healthy China Action defined the roles and main targets to be achieved by the government, society, families and individuals respectively, which not only clarified the responsibilities and division of labor, but also helped to form a "combination boxing".

  — — Personally, the Healthy China Initiative proposes to encourage moderate-intensity exercise for more than 30 minutes three times a week, or to accumulate 150 minutes of moderate-intensity or 75 minutes of high-intensity physical activity. Try to move as much as possible in your daily life, and achieve 6000 to 10000 steps of physical activity every day.

  — — Socially, the Healthy China Action proposes that fitness organizations around the masses should be established and improved, sports associations should achieve full coverage in cities, counties and townships, and individual sports associations should be extended to the masses, so that people who want to exercise can join the sports organizations.

  — — At the government level, the Healthy China Action proposes to promote the construction of basic public sports service system, coordinate the construction of national fitness venues and facilities, and build a number of national fitness venues and facilities such as sports parks and community fitness centers.

  Promote national fitness into families and encourage the development of national fitness volunteer service … … Lang Wei, director of the Group Department of the State Sports General Administration, said that the Healthy China Action hopes to make the people "move" towards health and exercise, so that hundreds of millions of people can work and live better and in the sunshine, and constantly release the new kinetic energy of healthy China. According to Xinhua News Agency, Beijing, August 7 th
