  In the field of intelligent hybrid, Bo Yue L has received technical support from Lei Shenqing Hi·X hybrid platform, which can bring users a high-value experience of no charge, long battery life, fuel consumption, pure electricity and mixing. Among them, the world’s first frequency conversion hybrid electric drive 3DHT PRO has 20 intelligent working modes and 3-speed ratio, which can realize full-speed domain parallel drive and power is on call. According to the test, the fuel consumption of the NEDC of Bo Yue L Lei Shenqing Hi·F oil-electric hybrid is only 4.2L, the comprehensive endurance of NEDC can reach 1300km, and the acceleration time from 0 to 50 km/h is only 3.5s.

  In terms of intelligent driving, Bo Yue L is equipped with NOA lane-level automatic driving navigation system initiated by Geely, which can realize automatic driving from point A to point B in high-speed elevated scenes, and the driver only needs to do necessary supervision to truly realize the change of driving subject from person to car. With the help of centimeter-level high-precision positioning, man-machine co-driving VR navigation and full-lane dynamic monitoring technology, the system can realize full coverage of more than 100 high-speed driving scenes, such as automatic ramp-up, automatic lane-changing evasion, automatic lane-changing overtaking, automatic avoidance of large trucks, automatic deceleration in corners, automatic speed control of confluence, and tunnel accident avoidance, so as to automatically find paths and drive, and liberate drivers’ hands to the greatest extent.

  Bo Yue L also creates an intelligent "mobile space" with temperature by means of multi-dimensional human-vehicle interaction. The world’s first surrounding emotional light curtain can express "emotion" by simulating voiceprint beat, breathing frequency, running water changes, etc. In interactive scenes such as voice interaction, music rhythm, nap mode and air conditioning linkage, with the change of rhythmic light and shadow, it creates a cockpit environment with a sense of ceremony and appreciation. Supported by Qualcomm Snapdragon 8155, the flagship in-vehicle chip, Geely Galaxy OS Air, the world’s first version, will bring users a silky and smooth consumer electronics-level interactive experience by launching a 13.2-inch vertical screen, a Free Touch UI, a short-link interactive design, a one-button direct high-frequency function and a V01 offline AI voice chip. In addition, Bo Yue L also uses 25.6-inch AR-HUD augmented reality head-up display, Harman INFINITY headrest audio and the world’s first intelligent AI microclimate housekeeper to innovate the full sensory ecological interaction experience.

  In the field of intelligent safety, Bo Yue L applies Geely’s original "seven-layer intelligent safety identification circle", which can provide comprehensive safety protection such as information safety, driving safety, assisted driving system, information assistance and safety warning, active disaster avoidance safety, passive collision safety, accident alarm and rescue.

  Digital Symphony Science and Technology Aesthetics, Refresh the World Expression of Chinese Aesthetics

  Corresponding to the innovative intelligent product strength, it is Bo Yue L’s innovative modeling design. As the first production car based on the "Vision Starburst" concept car, Bo Yue L adopted a brand-new design concept of "Digital Symphony Science and Technology Aesthetics", which not only inherited the classic "Ripple" design elements, but also organically integrated the sense of intelligent science and technology, futuristic sense and oriental aesthetics, and perfectly interpreted it with visual symbols such as interlacing, twisting, extending and pulsing, which interpreted the spirit of blending and innovation in China traditional culture and refreshed the world expression of Chinese aesthetics again.

Geely's latest intelligent SUV, Bo Yue L, will be unveiled as an innovator in the "Easy Car Super 818 Car Carnival Night".

  From the details, Bo Yue L’s "Light Wave Ripple Front Grille" brings a feeling of infinite expansion and extension with a parametric design, bringing a magnificent, dynamic and cool new visual experience. The particle ray lamp group consisting of 182 LED light-emitting units has the functions of welcoming/seeing off/locking the car and putting off the lights, which adds more sense of ceremony. At the same time, the combination of the particle ray lamp group and the brand-new Geely logo, which can light up, seems to open the dimension door leading to the digital world, making the whole front face more and more profound and mysterious.

  Bo Yue L is designed with two-color body and suspended roof. The tidal waist line extending from the front wheel eyebrow straight up to the rear window, combined with the 20-inch silver-black star disc large-size wheel hub, gives Bo Yue L more movement and passion. The new car is also equipped with an antiviral door handle with a sterilization rate of more than 99%, which can inhibit the growth of bacterial viruses for a long time. The body size of Bo Yue L is 4670×1900×1705mm, and it has a super-long wheelbase of 2777mm leading in the same class. Combined with the short front and rear suspension design, it forms a leading axle length ratio of 59.5% in the same class, which not only brings stable handling, but also brings more ample longitudinal practical space for the car.

As soon as Lynk & Co made a big move, other brands were weak

Perhaps it was just a coincidence that Geely chose to officially release the Geely SEA Vast Intelligent Evolution Experience Architecture the day after the "Tesla Battery Day". To be fair, although Tesla had made a lot of progress in battery technology, compared to the many technical highlights of the SEA architecture released by Geely this time, it was really weak.

In a way, this is not just a pure electric vehicle platform for Geely. According to my understanding, the SEA vast architecture is simply a huge high-tech "ammunition" created by Geely for the development of future pure electric vehicles and smart cars. The Lynk & Co ZERO concept car unveiled that night is the first model based on the SEA architecture, and the production version will be delivered in the second half of 2021.

When I was at the scene and saw the technical indicators that were printed on the screen, I was really shocked. Here are a few of the most critical technical indicators to chat with you.

 

First of all, the SEA architecture can adapt to the wheelbase from 1800-3300mm, A-class car to E-class car all model specifications, in addition to sedans, MPVs, SUVs, and even support pickup trucks. This is really impressive. What is the concept of 1800mm and 3300mm wheelbase models? The recent Internet celebrity model Wuling Hongguang MINI EV has a wheelbase of 1940mm, while Mercedes-Benz’s new generation S-Class has a wheelbase of 3216mm.

Does it feel a little scary to think about it carefully? The compatibility and scalability of SEA’s vast architecture is indeed amazing, enough to allow Geely’s brands to easily create high-performance but differentiated pure electric models. This means that Geely’s brands will have a huge advantage in both the research and development cycle and the cost of R & D and production. According to official data, the development time of new pure electric models in the future will be shortened by 50% compared with the past.

 

Is this kind of play a bit familiar? Volkswagen Group did this, but in order to distinguish between ordinary electric vehicles and high-end luxury electric vehicles, Volkswagen created two pure electric platforms with different positioning, MEB and PPE, respectively, but the scalability of each platform is not so great. But Geely did not do this, relying on a SEA architecture to win the world.

From this perspective, the technical value of the SEA architecture is obviously higher. You know, electric vehicles with a wheelbase of more than 3 meters will have significantly higher requirements for the performance, driving control performance and even various safety of the three-electric system. For the three-electric system under the SEA architecture, Geely has set technical indicators today, which are quite leading even in the world.

 

The battery has always been the core of pure electric vehicles. At the press conference, Geely announced that the pure electric vehicle with SEA architecture will be equipped with the longest life battery in the world, which can ensure 200,000 kilometers without attenuation and 2 million kilometers long life under NEDC conditions. Among them, the NEDC cruising range of 110kWh modular CTP integrated battery pack is "easy" more than 700 kilometers. This word "easy" is indeed the original words of the scene.

Even on a fuel car, 200,000 kilometers of mileage means that for the vast majority of car owners, it takes nearly 10 years of long-term use. So Geely’s subtext is very straightforward, that is: battery life is much longer than the life of the car body.

 

However, since there was no detailed introduction at the meeting, what technology or new materials did Geely use to achieve the ultra-long life performance of the battery, this suspense can only be left for future research.

 

In terms of electric drive, Geely’s SEA architecture supports high-performance electric four-wheel drive systems, which means that models with front and rear dual motors will definitely be launched. Geely has also independently developed a high-performance two-speed electric drive transmission with a maximum load-bearing torque of 8000 Nm. Another thing that particularly caught my attention is that the SEA architecture is compatible with high-voltage systems from 400 to 800V, which can be charged for 5 minutes and have a battery life of 120 kilometers.

Many people may not know what the use of 800V high voltage system means. Let me give you the most intuitive reference. At present, the Porsche Taycan is the first mass-produced electric vehicle in the world to use 800V high voltage system. Most other pure electric vehicles still use 400-500V voltage system. Using a 400V system means that the working voltage of its motor, battery, electronic control and other related systems is in this range.

 

What are the benefits of an 800V high-voltage system? Let’s do a simple popular science first. Friends who have studied physics in middle school know that power = voltage X current, so at the same power, the higher the voltage, the smaller the current. Smaller current can not only reduce the loss of power and reduce the heat generation of circuit components (which is crucial for electric vehicles), but also prolong the life of electronic parts.

The benefits of using a high-voltage system are many, but the most direct and obvious benefit for users is the increase in charging speed, or this is the confidence that the SEA architecture can achieve 120 kilometers of charging in 5 minutes. At present, the Porsche Taycan natively supports the use of 250kW high-power fast charging, and it is said that it can also support 350kw fast charging. Maybe, Geely can do it in the future.

 

But achieving high voltage is not an easy task, involving all aspects of technology and cost. Of course, Geely cannot use the 800V voltage system in all future models, especially the low-end entry-level models are likely to still use the 400V system, but from the SEA architecture setting, Geely is ready to launch high-performance high-end large-scale electric vehicles in the future.

 In terms of autonomous driving, according to Geely’s official statement, SEA’s vast architecture has the ability to meet the requirements of fully autonomous driving, and can support the implementation of autonomous driving functions such as hands off, eyes off, autonomous parking, automatic lane change, and automatic navigation.

Is this a big pie for us? Geely said that personal vehicles based on vast architectures will achieve a high degree of autonomy on structured roads in 2021; by 2023, they will achieve a high degree of autonomy on open roads. Whether it can be realized by then, we will wait and see.

Finally, let’s talk about some information about this Lynk & Co ZERO concept car.

 

The ZERO concept car on the scene has a very high degree of design completion, and I believe that there will not be many changes in the future production version. The front face is still a family design, but it is visually flatter and has a lower center of gravity, with a bit of style similar to Volkswagen Scirocco.

Looking at the profile of the side, the body line is more slender than that of an ordinary hatchback car, but it does not reach the proportion of a station wagon, which is a bit like the scaled-down version of the Porsche Panamera. The through-type tail lights are even more the finishing touch, and the visual effect is much cooler than the tail lights of the Audi A8.

Lynk & Co officially positioned this car as a "luxury pure electric coupe". As for how luxurious the interior is, because the interior has not been officially released, it is not known, but from a fleeting picture in the official video, it can be seen that the center console adopts a new design. The light-colored part is likely to be covered with leather materials, and the overall look is quite a bit of Volvo’s Nordic home style, but in the end, it can only be determined after the interior is released.

As for whether it could live up to the three words of high performance, the official data released so far was very limited, only revealing that the car used a height-adjustable air suspension and a frameless electric door design. This electric car with a length of more than 5 meters and a wheelbase of nearly 3 meters, the acceleration time of 100 kilometers was controlled within 4 seconds.

 When describing this car, there is a sentence that really impresses me. Mr. An Conghui, CEO of Geely Group, said: We don’t make boring smart electric cars.

 

Just this sentence alone is enough to make people look forward to it. Finally, you might as well leave a message to predict, how much do you think the final price of this production version of the car will be?

Authoritative experts respond to hot issues in Covid-19.

  [Report from the press conference of the State Council Office]  

  Guangming Daily, Beijing, July 22nd, by Guangming Daily reporter Yuan Yufei

  On July 22nd, the State Council held a press conference on the traceability of Covid-19. Xu Nanping, Vice Minister of Science and Technology, Ceng Yixin, Deputy Director of the National Health and Wellness Commission, Wang Chen, Vice President of China Academy of Engineering, Dean of Peking Union Medical College and Director of the National Respiratory Medicine Center, Liang Wannian, Chinese leader of the China-World Health Organization joint research group on Covid-19 traceability, Yuan Zhiming, director of Wuhan National Biosafety Laboratory of Chinese Academy of Sciences and researcher of Wuhan Institute of Virology, and other authoritative experts actively responded to the hot issues of the traceability of the new coronavirus concerned by Chinese and foreign media.

  Q: Is the report on global traceability in Covid-19 released by the World Health Organization on March 30th authoritative?

  Ceng Yixin:The problem of virus traceability is a complex scientific problem. Since the outbreak of the epidemic, every responsible country and every responsible scientist is eager to find out the source of Covid-19. This is of great significance to prevent similar epidemics from happening again.

  On March 30th this year, the World Health Organization officially released the joint research report "Global Traceability Research in Covid-19: Part of China" convened by WHO, and the global traceability research made a good start.

  Governments, scientists and the media all over the world are very concerned about this report. Since its release a few months ago, more and more scientific evidence shows that this report is valuable, authoritative and can stand the test of science and history. The conclusion of the report is scientific, and the process of production always adheres to scientific principles.

  This traceability research report is the China part of the global traceability research. The expert group draws the following conclusions: Coronavirus, which is closely related to Covid-19, has the highest homology with Covid-19 in terms of sequence, but these viruses are still not enough to prove that they are the direct ancestors of Covid-19, and there is still a certain gap. Combined with the research results of clinical epidemiology, animal and environmental detection, the joint expert group finally determined several possibilities for the virus to appear: the first one is "possible to relatively possible", and zoonosis directly overflows, that is, it directly overflows from animal hosts to people. The second is "more likely to be very likely", which is introduced through an intermediate host. Generally speaking, the natural host of the virus is an animal, and then it transits to people through the intermediate host. The third is "possibility", which is introduced through the cold chain. In some sporadic epidemics in various places last year, it was found that cold chain transmission may introduce viruses. The last one is the introduction of "extremely unlikely" in the laboratory.

  In the next stage, the traceability work should be carried out under the overall coordination of WHO, and on the basis of the first stage of research, excellent experts from many countries should be organized to carry out in-depth work, scientists should be the mainstay, exchanges and cooperation should be strengthened, and the traceability work in Covid-19 should be carried out on a scientific track.

  Q: Is Covid-19 naturally produced or caused by human factors?

  Ceng Yixin:I really want to talk about my views on the second phase of the virus traceability plan released by WHO on July 15th. To tell you the truth, I was very surprised. Because in this plan, the hypothesis that "China violated laboratory regulations and caused virus leakage" is one of the research focuses. From this point, I can feel the disrespect for common sense and arrogant attitude towards science revealed in this plan. It is impossible for us to accept such a traceability plan.

  What is the purpose of traceability? It is to find out the source of the virus and then take effective measures to prevent similar epidemics from happening again. Therefore, we must promote this work in accordance with scientific principles and rules. This is the attitude of the China Municipal Government.

  So far, none of the staff and graduate students of Wuhan Institute of Virology has been infected with COVID-19. Wuhan Institute of Virology has not carried out research on the gain function of coronavirus, and there is no so-called artificial virus. So where did the virus leak due to violation of laboratory regulations come from? Therefore, this formulation violates both common sense and scientific laws. More importantly, the WHO expert group personally visited Wuhan Virus Institute, and reached the conclusion that the virus is extremely unlikely to be leaked from the laboratory. They are all very authoritative and experienced experts in various fields carefully selected by WHO. So we should respect their conclusions.

  Yuan Zhiming:The Wuhan Institute of Virology has repeatedly responded to the rumors about the leakage of virus laboratories. Covid-19 originated from nature, which has become a general consensus in academic circles. I want to emphasize that before December 30, 2019, Wuhan Institute of Virology had not contacted, preserved or studied Covid-19. Wuhan Virus Research Institute has never designed, manufactured or leaked Covid-19.

  Facing the sudden outbreak of COVID-19, Wuhan Institute of Virology quickly identified novel coronavirus with the advantages of platform, technology and talents accumulated for a long time, isolated the virus strain, determined the whole genome sequence, and submitted the whole genome sequence to the United Nations World Health Organization on January 12, 2020. These important research results have provided a foundation for the global antiviral drug screening and vaccine research, and also won time for the global fight against the epidemic.

  Q: Is the original data of early communication in Wuhan public?

  Yuan Zhiming:The structure and content of the database of Wuhan Institute of Virology are still in the process of continuous improvement. At present, the database is shared within Wuhan Institute of Virology. After analyzing and systematically sorting out some original data in the database, the staff will publish the research results in the form of papers, and display and retrieve them in the database in a visual way. After analyzing and sorting out the original data of scientific research, it will be published in the form of papers, and then the database will be made public. This is the practice of scientific and technological circles, and the Institute of Virology will strictly follow the rules of scientific and technological circles to display and share our scientific data.

  Wuhan Institute of Virology has always insisted on the timely sharing of scientific research information, and we released the whole genome sequence to the World Health Organization in time. As early as February 3, 2020, Shi Zhengli’s research team published a research paper in Nature, proposing that Covid-19 came from nature. After we found that several drugs have antiviral activity at the cellular level, we published the research results in international magazines on February 4. At the same time, Wuhan Virus Research Institute also actively participated in the international video and audio conference held by the World Health Organization, and timely shared our research results in animal model establishment, antiviral drug screening, inactivated vaccine development in COVID-19, etc.

  Q: What do you think about the possibility of virus spread caused by trade in cold chain products?

  Wang Chen:The role of cold chain in the spread of infectious diseases is a new phenomenon. From Beijing Xinfadi epidemic situation and Qingdao epidemic situation, we can see such a close relationship, that is, the patients have been exposed to the cold chain, and no other possible virus sources have been found outside the cold chain.

  In the detection of virus nucleic acid, cold chain goods nucleic acid detection is positive. Especially in the Qingdao epidemic, not only the virus nucleic acid positive was detected on the surface of cold chain items, but also the virus was isolated and cultured, which confirmed that there was a live virus on the surface of cold chain items. Combining these two points, the chain of evidence is gradually complete.

  In the process of further virus traceability, we especially suggest that the cold chain should be regarded as a key traceability clue. At present, under the background of international trade, people and goods exchange frequently all over the world, and people in the cold chain environment — The spread of things has increased the complexity, which is particularly worthy of investigation and research.

  Guangming Daily (July 23, 2021, 09 edition)

What gift did Xu Wen’s fruit grower give to the "pineapple goddess" after traveling 500 kilometers?

  It’s less than half a month before the Mid-Autumn Festival. On the morning of September 12th, Xu Wen, a fruit grower, traveled 500 kilometers to Guangzhou to give Li Xiaojun, the leader of the pineapple "12221" working group, a freshly baked gift of Xu Wen’s Mid-Autumn Festival. Li Xiaojun, who just retired last year, received unexpected surprises from Xu Wen from time to time. Before that, she received newly opened pineapple flowers and fresh-cut small pineapples from Xu Wen. This time, she received the pineapple moon cake launched by Xu Wen for the first time, which just witnessed Xu Wen’s advanced road from selling pineapples to selling pineapple prefabricated dishes and pineapple food. Not long ago, Luo Hongxia, secretary of Xuwen County Party Committee, and Huang Laixing, county magistrate, also distributed invitations to share the sweet and unique "pineapple sea" moon cakes.

  Xuwen fruit grower: There are always stars to clear the way, and there are always you coming for us.

  "I have worked all my life, done many jobs and things, and made many friends. What makes me feel the value of my work most is ‘ The Sea of Pineapples ’ 。” Li Xiaojun said that in the "12221" work carried out in Xuwen, he met the most human "Xuwen people".

  Li Xiaojun was the leader of the pineapple "12221" working group of the Guangdong Provincial Department of Agriculture and Rural Affairs and one of the promoters of Xu Wen’s pineapple "counterattack". He just retired from his job last September. At that time, Xu Wen, a fruit grower, gave her a painting with a moving sentence: "There are always stars to clear the way, and there are always you coming for us."

  Time goes back to five years ago, Li Xiaojun was "ordered at a critical moment" and stationed in Xuwen with a five-member working group. At that time, Xuwen pineapple was slow-moving, and the selling price of the local traditional pineapple variety Bali’s Tiantou was only 0.40 yuan/kg at the lowest in 2018. The pineapple rotted in Xuwen Tiantou and rotted in the hearts of fruit farmers. In order to solve the pain point of "increasing production of Xuwen pineapple without increasing income", the Guangdong Provincial Department of Agriculture and Rural Affairs formed a Xuwen pineapple special working group in February 2019 to carry out special research on the construction of the "12221" market system of Guangdong pineapple.

  With the spirit of nailing, the working group entered Xuwen, and together with the xuwen county Municipal Party Committee and County Government, created the "12221" replicable and scalable model of Xuwen pineapple. The members of the working group with their own strengths have changed from time to time, but the team leader Li Xiaojun is like a needle in the sea, firmly holding the initial intention of "doing practical things for fruit farmers." Under the leadership of Li Xiaojun, the working group crouched in Xuwen, and according to one stage and one key point, it boosted the sales of pineapples, guided the variety improvement, promoted farmers to get rich and promoted rural revitalization.

  Starlight does not ask the passers-by, and time pays off. The working group held up a set of heavy figures: in 2023, Xuwen planted 350,000 mu of pineapple, with a yield of 1.5 billion Jin and a net income of 1.5 billion yuan for farmers.

  In recent years, Xuwen pineapple has not only become a rich fruit, but also "counterattacked" to become the "vanguard" of high-quality agricultural products in Guangdong. The sale of pineapples has given Xuwen people a full sense of acquisition and happiness, and has also made a "good start" for Guangdong’s bulk agricultural products, becoming a model "barometer" for the price of good fruits in Lingnan. The marketing of "pineapple sea" is the "first stick" of agricultural products marketing in Guangdong, and then it drives litchi, longan and grapefruit to run out of success.

  Li Xiaojun: Xu Wenren endowed "12221" with new content and higher value.

  This time, Xu Wen’s fruit farmers sent Li Xiaojun a freshly baked "pineapple sea" moon cake, which was also the first pineapple moon cake launched by Xu Wen, which made Li Xiaojun particularly surprised.

  Although one out of every three China pineapples comes from Xuwen, there was only a single canned product in the local pineapple processing before. In recent two years, with the vigorous promotion of the Guangdong Provincial Department of Agriculture and Rural Affairs, Xuwen made great efforts in the food-oriented project of agricultural products. This year, the fresh-cut small pineapples won a great victory and were sold nationwide, and the pineapple prefabricated dishes also became an explosion. By doing a good job of "native products", pineapple processing industry has reached a new level.

  "When I just retired last year, Xu Wen’s old friends came to see me. I was very moved. The happiest thing is that Xu Wen people can plant and sell, and they also sell at a good price. This year, friends from "Sea of Pineapples" came to see me again. I am very grateful. The happiest thing is to see pineapple moon cakes, which Xu Wenren gave me ‘ 12221’ New content and higher value. "

  Just last month, the Guangdong Provincial Department of Agriculture and Rural Affairs and xuwen county held an exchange forum in Guangzhou. All-media reporters of Yangcheng Evening News learned at the meeting that this time Xuwen attracted Dole. It is foreseeable that the addition of Dole, a world fruit processing factory, will drive Xuwen’s pineapple processing industry to a higher level. The agricultural product processing industry extends from the breeding industry, which is an inevitable stage of agricultural modernization.

  "Make meaningful things interesting, make interesting things valuable, really do it, do it quickly, and do it for a long time." Li Xiaojun said that this is the consensus of colleagues in the "12221" working group. "Looking back now, five years of persistence, the sea of pineapples ‘ 12221’ The members of the working group are very happy to have done something meaningful, interesting and valuable. "

  Call the world to eat "pineapple sea" moon cakes! Xu Wen sent an invitation letter.

  At the end of August, Luo Hongxia, secretary of Xuwen County Party Committee, and Huang Laixing, county magistrate, distributed an invitation letter inviting friends all over the world to share the sweet and unique "pineapple sea" moon cake.

  The invitation letter said: In 2023, with the enthusiastic help of buyers and consumers all over the world and the support of the "12221" market system, the beautiful and sweet "pineapple sea" will be full of gold and honey. We followed the drum beat of "High-quality Development Project of 100 Counties, 1000 Towns and 1000 Villages" and did a good job in Xuwen pineapple "Native Products" article. We promote new varieties, expand the big market, and promote hundreds of live broadcasts; We extend the pineapple industrial chain and implement the pineapple industrialization, food and festival projects. We combine the natural beauty of Xuwen’s "pineapple sea" with the cultural beauty of Mid-Autumn Festival, adopt unique fresh-keeping technology, and innovatively produce unique "pineapple sea" moon cakes with full natural pectin texture. Pineapples are reunited, homesickness is integrated into moon cakes, tenderness of red land and delicate integration of moon cakes, and the unique taste seems to bring us back to our hometown … …

  Not only that, this Mid-Autumn Festival, the "pineapple sea" is still quietly brewing a surprise in the moonlight, which is waiting to be announced.

  "For a moment, it suddenly occurred to me that if people will come to see me next year, what good news will they bring?" Li Xiaojun said: "I am particularly worth looking forward to!"

Awesome! Changsha, a high school student, won the national special prize.

Recently, the results of the fourth Peking University "Yanyuan Cup" middle school students’ historical writing competition were announced, and Liuyang Xinhan High School student Mao Ziguan was on the list.
He is the only student in Hunan Province who won the national special prize.
After several rounds of review, cross-grading, and online interviews without leading groups, the hair was crowned.
The article "Thousands of Trees Bloom in the East Wind at Night-A Review of the Development of Liuyang Fireworks" stands out from 3000 students in China.
Mao Ziguan, who likes reading literature and history books, loves to study, think and express, has a passion for history.
Speaking of why he wrote Liuyang Fireworks, Mao Ziguan said that Liuyang Fireworks is the pride of his hometown, and his father is also a fireworks worker. He has been fascinated by the fireworks culture since he was a child, and he wants to use the opportunity of Peking University’s "Yanyuan Cup" to show you the other side of Liuyang Fireworks.
Mao Ziguan said that the academic task of senior two is also very heavy. The writing of the article basically took self-study and weekends to write, and it took more than two months from conception to completion. In the early stage of writing, he spent nearly a month visiting Liuyang Library, Archives and other places. In order to verify more information, he also interviewed a number of fireworks entrepreneurs in Liuyang.
"I hope that the Liuyang fireworks industry will develop better and better, and I hope that more people will know and understand the historical course of Liuyang fireworks."
Next, the award-winning works of Mao Ziguan will be

introduction
My hometown, Liuyang City, is located at the border of Hunan and Jiangxi, and is called Liuyang because it is located in the north of Liushui (the water in the south of the mountain is Yang in the north). She is adjacent to Changsha City in the west and Tonggu County and Wanzai County in Jiangxi Province across Dawei Mountain in the east. In 1993, Liuyang was removed from the county to set up a city (county-level city), so the older generation here often called Liuyang "Liuyang County and City" when talking with people. Liuyang is not an unknown small county town. When locals go to other places and say that they are from Liuyang, outsiders will hear about it. The factor that makes Liuyang famous in China, apart from the song "Liuyang River" sung all over the country, is probably the fireworks printed with the words "Liuyang, Hunan" in the hands of ordinary people on holidays. What Liuyang people call "fireworks" is actually a general term for fireworks and firecrackers, which are crisp and provide auditory stimulation; Fireworks are dazzling and pursue visual enjoyment. Liuyang’s fireworks industry, whether firecrackers or fireworks, is a well-known and powerful local pillar industry with a long history and rich inside information, and there is a saying that "the goods in the market are only called Liuyang fireworks". [1] For most people in Liuyang, Liuyang fireworks are not only an indispensable part of daily life, but also play a powerful role in promoting Liuyang’s economic development.
Although I am from Liuyang, Liuyang is not the city that greeted my first cry. I live in Shenzhen with my parents, so my childhood memory happened in Guangdong. I only knew Liuyang was my hometown at that time, but I didn’t know where she was, her appearance, and the fireworks industry on which she relied. After returning to Liuyang, I gradually learned about Liuyang and the loud firecrackers and gorgeous fireworks that Liuyang people are proud of. Every Chinese New Year, the elders at home will buy all kinds of fireworks for us to set off. The spinning hot wheels spewing out Mars, the flying field mouse and the rocket launcher flying into the sky together constitute the most splendid picture in my childhood. When I entered the middle school stage, with the study of history, I jumped out of my mind with questions: How did Liuyang fireworks develop? Why does Liuyang’s fireworks production and sales surpass other places? What influence does the rise and fall of Liuyang fireworks industry have on Liuyang people and their lives? To this end, I visited some friends and consulted some materials, which was a brand-new experience and gave me a lot of feelings and enlightenment. Next, I sort out the information at hand and analyze and discuss the development history of Liuyang traditional and modern fireworks industry from the perspective of Liuyang locals.
chapter one
First, the legend and inheritance of Liuyang fireworks industry
"There are thousands of trees in the east wind night, and the stars are like rain."
Xin Qiji, a poet in the Northern Song Dynasty, described such a night scene of the fire tree and silver flower in the Shang Dynasty. Every time I read this word, I always think of the "catkin peach blossoms" that light up the villages and towns in the sky at my doorstep and the "falling sparks" that fall into the world a little bit after the annual observance.
There is also a sentence of "the night of the star bridge, the fire tree is blooming at night, and the lights are shining in the moonlight" in the poem "Jieyu Flower" by Yang Zemin, a poet in the Song Dynasty. This grand scene in Song Ci is not only a symbol of economic prosperity in Song Dynasty, but also a strong evidence of the prosperity of fireworks in Song Dynasty.
In fact, as early as the Sui and Tang Dynasties, fireworks had already entered the historical stage. The earliest poem I can find about fireworks is Yang Guang’s "On the 15th day of the first month, put lanterns on the thoroughfare and build a tower at night", which includes "Falun Gong turns in the sky, and Brahman sounds in the sky. The lamp tree shines thousands of times, and the flowers bloom seven times. The "Falun", "lamp tree" and "fireworks" in the poem should refer to the early fireworks.
Fireworks were formerly firecrackers. There are many legends about the origin of firecrackers, among which the story of "Nian Beast" is the most famous. This story has no age to test, and its historical value is relatively small. In the northern part of the Hunan-Jiangxi border, the legend of Li Wan, the "founder of fireworks", is still circulating among the people, with a clear age and figures, which seems more credible.
The legend of "the founder of fireworks" goes like this: According to legend, in the Tang Dynasty, mandrill riots broke out in various places, and people were harmed by them. When the news reached the ears of Li Shimin, Emperor Taizong, he was worried, so he sent a letter to seek medical treatment. Li Yi, from Dayaoshan, South Township, Liuyang, developed firecrackers, which were used to drive away spectres, intimidate wild animals and even drive away evil spirits from Taizong. Li Yi was named "the founder of firecrackers" by Taizong because of his meritorious service in rescuing the driver. Since then, with the development of local fireworks industry, Li Yi’s reputation has become louder and louder, and the people have also built his ancestral temple. With the support of local people, China Fireworks Culture Museum, the first village-run museum in China, was established in Dayao.
Legends, though interesting, cannot provide favorable historical evidence. The earliest reliable written record of Liuyang firecrackers is in the Liuyang County Records written by Kangxi in Qing Dynasty: "Later generations made a roll of paper as a tube, which was actually called a big firecracker, and the name of the giver was Chun Lei. On New Year’s Eve, there was a lot of noise. There are people in the county who compete with each other to make a bold move. " Secondly, it is found in China Industrial Records and Hunan Economic Survey Series published in the Republic of China: "The manufacture of firecrackers in Hunan Province began in the Tang Dynasty and developed at the end of the Song Dynasty" and "Hunan Whip". The production of guns first originated in Liuyang, and then with the development of the industry, the production area was gradually extended to neighboring counties. " [2]
The appearance of fireworks is vague, but its appearance time is later than firecrackers. After all, the production technology of fireworks is more difficult than firecrackers. In the fifteenth night of the first month written by Su Weidao, a poet in the Tang Dynasty, there is a poem: "The fire tree and silver flowers are combined, and the star bridge is locked." There is an explanation for the description in the poem that it is fireworks. In addition, the phrase "silver flowers on a flaming tree" has become one of the commonly used idioms in Chinese, which has a certain influence on the literary creation of later generations. In the eighteenth chapter of A Dream of Red Mansions, there is a sentence of "I only see the court burning around the air, the fragrant snow spreading on the ground, the flaming tree blooming, and the golden window jade sill". The production of fireworks in the Tang Dynasty was relatively simple, and the main process was to put the drugs available for discharge into bamboo tubes or wooden barrels, which was then called "bamboo tube fireworks" (tube flowers) or "barrel fireworks" (barrel flowers) [3]
A long history is a favorable condition. Besides, abundant non-ferrous metal resources have also promoted the development of fireworks industry. "There are 61 kinds of proven minerals and 190 known mineral sites in Liuyang City, among which sepiolite, pyrite and phosphate rock rank among the top ten mineral resources reserves in China." [4] Relying on the abundant local natural resources, Liuyang fireworks industry can be self-sufficient in raw materials, without relying too much on external materials.
Fireworks production is a labor-intensive industry, and Liuyang has more labor resources. The population of Liuyang increased from 72,000 to 775,000 from 1391 to 1949. [5] During the 500-odd years from the 24th year of Hongwu to 1949, the population of Liuyang generally increased.
From another point of view, Liuyang is mountainous and hilly, with broken cultivated land and few plains. "(Liuyang City) landform types: mountains account for 52.85%, hills account for 25.8%, hills account for 7.87%, plains account for 12.56% and water accounts for 1.64%." [6] There are many natural disasters in Liuyang, such as the drought in the first year of Hongzhi in the Ming Dynasty (1488), and the history of "people eating bark and accumulating corpses", and the flood in May in the thirteenth year of Kangxi in the Qing Dynasty (1647), "there are countless people and animals floating in the four townships, and more than a thousand bad fields are dumped". Frequent natural disasters, broken arable land and the government’s "grain abortion" policy are not conducive to the normal production and operation of agriculture. Therefore, in the Ming and Qing dynasties, when the productivity was more developed than that of the previous generation, a large number of laborers turned from agriculture to handicrafts. In the famine years, this situation is more common, and this phenomenon is also conducive to the development of fireworks industry.
Relying entirely on agriculture, farmers’ livelihood can not form a stable guarantee, coupled with disasters such as famine, resulting in a large surplus labor force in Liuyang. This phenomenon still has some influence today. With the hard work of Liuyang working people, Liuyang fireworks industry has made great progress.
In the 17th century, "Liuyang has produced a large number of firecrackers". [7] The production of fireworks flourished in the early Qing Dynasty. In the first year of Yongzheng, Liuyang presented a new variety of fireworks to the court. [8] This promoted the popularity of Liuyang fireworks and firecrackers. During the Qianlong period of Qing Dynasty (1736-1795), the production technology of Liuyang fireworks became more and more mature and became the "center of Hunan firecrackers manufacturing". [9]
In short, the development of Liuyang fireworks industry in the early Qing Dynasty laid the foundation for today, and the development of Liuyang fireworks industry in the future will also play an important role in the happy life of Liuyang people. For details, see below.
Second, the modern Liuyang fireworks industry
The development of modern Liuyang fireworks is tortuous, which is also closely related to the introduction of modern ideas, the disintegration of natural economy and the deepening of semi-colonization.
With the introduction of modern ideas, the government’s attitude towards industry has changed greatly. At first, it was regarded as "strange skills and cunning", and later it was turned into encouragement and support. Liuyang fireworks, which developed before modern times, as a national enterprise, is naturally valued by local governments. Of course, Liuyang fireworks industry is profitable and profitable, which makes it coveted by many forces at home and abroad, coupled with security risks and heavy taxes, but also faces some unfavorable factors.
Fireworks are gunpowder products, and some processes such as mixing, building, making Liangzi, inserting and whipping are all related to gunpowder, so the risk factor is high. In old China, the security situation was worrying. At that time, most of the fireworks and firecrackers were scattered in small workshops. According to personal preferences, drugs, paper, semi-finished products and finished products were piled up everywhere, which was chaotic. Once a fire broke out, the consequences were unimaginable.
In fact, whether the fireworks industry is "high risk" depends not only on the industry itself, but also on the institutions that manage the industry and whether the people engaged in the industry attach importance to safety. The old government only asked for more production and more taxes, and paid no attention to safety in production. As can be seen from the Whip Explosion in Hunan compiled in 24 years of the Republic of China, there are seven chapters in the book, which involve the types and producing areas, manufacturing raw materials, manufacturing procedures, packaging, export, market research, development approaches, etc. It seems to be comprehensive and detailed, but nothing is said about safety in production.
The old government sometimes interfered with the normal operation of the fireworks industry at will. In 19 years of the Republic of China, the Kuomintang sent troops to "encircle" the Soviet area, and the output of firecrackers was blocked. The annual output dropped from more than 200,000 boxes in 6 years of the Republic of China to more than 4,000 boxes. In 21 years of the Republic of China, the Kuomintang government called firecrackers superstitious, banned production and sales, and imposed heavy taxes on finished products. After the protests of the masses and the refutation of the squire, the government was forced to take back its mandate. During the Anti-Japanese War, it was hit by the war again, and there was a period of recovery after the war. In 36 years of the Republic of China, it rose to 82,000 boxes. In 37 years of the Republic of China, the Hunan Provincial Department of Finance levied a special donation of firecrackers, which was aroused by public excitement and forced to be cancelled. The government’s influence on the output of fireworks industry is undoubtedly enormous. [10]
The people have supplemented the shortcomings of the government to a certain extent. Firecracker merchants in the county organized "Firecracker Trade Association" to manage the external production and sales of fireworks. Firecrackers in the county are all transported and sold by private blasting villages, which are divided into general, branch, generation and sub-villages. At that time, the famous explosion village was the first to promote Pei Dehou, Yuan Heli and Qian Dali. Pei Dehou’s boss is Ding Jing ‘an. Xianfeng helped his grandfather to run the firm at the end of the year and took charge of the business two years later. During the Tongzhi period, he operated fireworks and set up branches in many places. Twelve years of Tongzhi, selling land and acting as commercial capital. During Guangxu’s reign, a branch was established in Hong Kong, and Liuyang firecrackers were the first to enter overseas markets. At that time, people called him "an outstanding talent in business". [11] In 12 years of the Republic of China, exploiters made huge profits and deducted their heads; Workshop Jerry-building, shoddy, coupled with "bad prices for each other, competing to sell", resulting in Liuyang fireworks reputation, sales dropped sharply, nearly half of bankruptcy. Afterwards, the "Blasting Industry Maintenance Meeting" defined the style of firecrackers and prohibited the manufacture and purchase of inferior goods. The inferior firecrackers and inferior raw materials in more than 60 cases of inferior firecrackers were confiscated and burned, and the manufacturers were fined and the time limit was corrected. The quality of Liuyang fireworks products was restored. [12] In fact, not only modern Liuyang fireworks merchants have a strong sense of social responsibility, but also contemporary entrepreneurs. Excellent fireworks entrepreneurs are enthusiastic about their own industries and even other industries. I remember that I once heard from a well-known barber that some fireworks entrepreneurs prefer to come to their own shops for haircuts instead of going to those luxurious barber shops, and their lives are simple and economical.Treat people in harmony and friendliness. With these good qualities, they have also become a great boost to the development of fireworks in Liuyang City.
Domestic and foreign markets have also expanded each other. Products are first judged by Baozhuang to determine the quality of production, determine the price and buy them, and then packaged, printed with brand numbers, boxed and shipped abroad. For export, it is mostly transported by water, and it is transported to Hankou and other places via Xiangjiang River. "In the early years of Guangxu, Hunan merchants tried to sell Liuyang firecrackers in Shanghai and Nanyang, which was very popular and sold widely. People in Hankou Xindi and other places, seeing the profit, are competing to sell Liuyang firecrackers. [13] Firecrackers sell well in Nanyang, where there are many Chinese, while fireworks have a broad market in Europe and America, which like entertainment. After the opening of overseas markets, the sales of Liuyang fireworks further expanded.
Although the production of fireworks developed in the early modern times, in the "Hunan Industrial Records" published in the 24th year of the Republic of China (1935), there was a saying that "the production of firecrackers, according to the recent survey, has gone far backwards". [14] After the Anti-Japanese War and Civil War, the fireworks industry was in a desperate situation. However, "there is no way for mountains and rivers to be suspicious, and there is another village." The fire of Liuyang fireworks is still there, just waiting for an opportunity.
chapter two
First, the rapid development of the fireworks industry
Liuyang Fireworks has gone through several stages, such as slow recovery, decline and pause, steady development, curve development and new development.
The first is the slow awakening stage in the early days of the founding of New China. Liuyang fireworks industry has experienced years of fighting and suppression, and finally ushered in a better domestic environment. From 1950 to 1952, the fireworks industry was in a downturn for a period of time, which was mainly caused by the classification of fireworks as "feudal superstition". The policy angle restricted production, so many fireworks factories closed down and the output of fireworks decreased. At the same time, the United States launched the Korean War, the coastal ports were blocked, and foreign exports were also restricted, but the witty Liuyang businessmen were still trying to make the fireworks industry tide over the difficulties.
On October 1, 1951, Li Wenchu, the shopkeeper of Liuyang "Li Simei" explosion village, hosted a fireworks display in Beijing on the second anniversary of the National Day, which greatly encouraged Liuyang fireworks. Since then, Liuyang fireworks have appeared in every major national celebration, and local governments have also realized the huge economic and social effects of fireworks industry.
In 1953, the Hunan Provincial People’s Government adjusted the fireworks tax rate, reducing it from 30% to 20%. [15] Since then, the fireworks industry has been on the right track, with a certain expansion in output and scale. However, due to the influence of agricultural simplification, the development is slow.
In 1962, the state implemented the eight-character policy of "adjustment, consolidation, enrichment and improvement" in the economic field, and all walks of life recovered, as did the fireworks industry. In 1962, the Liuyang County People’s Government Committee ordered the relevant departments to rectify the market, and at the same time, comprehensively inspected the production and business units in the county, eliminated nearly 10,000 boxes of inferior fireworks, and re-established the quality standards of fireworks products. Those that failed to meet the requirements were not purchased. At that time, it was still a planned economic system, and the products could not be put into the market. Failure to be purchased meant that the products could only rot at home or in factories. In this way, the frequency of shoddy industries could be reduced to a certain extent.
In 1965, Liuyang County Supply and Marketing Co., Ltd. also took the initiative to go out and apologize to the main sales ports in the country, to ensure strict control of product quality, and to eliminate the inferior firecrackers that had been shipped out. The reputation of fireworks has been restored, which shows that Liuyang has made great achievements in grass-roots management.
The development during the "Cultural Revolution" had ups and downs. Fireworks are once again listed as superstitious supplies, and the traffic is not smooth when "sports" are carried out everywhere, and foreign trade exports are also blocked, which has caused adverse effects. However, the production of fireworks did not stop, because the fireworks enterprises were also called "social team enterprises" at that time, and most of them were scattered in rural areas, and the impact was less than that in cities. In addition, the poor management of state-owned enterprises during this period resulted in a large backlog of raw materials, which led to the relatively cheap prices of raw materials for fireworks production, such as paper and gunpowder, and provided some conditions for fireworks production. By 1971, the output exceeded the highest level in history, reaching 274,700 cases; By 1978, the output reached 429,500 cases, exceeding the historical highest annual output of 71.8%.
In 1978, with the gradual deepening of reform and opening up, the external conditions of Liuyang fireworks industry gradually improved. As the demand for raw materials such as home-made paper, potassium chlorate and potassium nitrate increased day by day, transportation from outside could not meet the requirements, so the localization and intensification of the industry were accelerated. So it also promoted the development of other related industries in Liuyang, such as paper industry and chemical industry. By 1987, the above-mentioned intermediate industries had grown to nearly 100, with an output value of nearly 50 million yuan and an annual tax revenue of nearly 4 million yuan. [17]
In 2011, there were 3,909 fireworks production enterprises in China, 1,982 in Hunan and 946 in Liuyang, accounting for 24.2% of the whole country and 47.7% of the whole province respectively. Liuyang fireworks account for 70% of the national production capacity, including 283 fireworks production enterprises with export qualifications and 926 fireworks raw materials enterprises. There are nearly 400,000 employees. Liuyang Fireworks has become a world-renowned cultural brand, and its products are exported to Europe and America.
Second, the new situation of fireworks development
As mentioned earlier, The Whip Explosion in Hunan, written during the Republic of China, made no mention of safety in production, which showed that the old government did not cherish people’s lives and property. After the founding of the People’s Republic of China, the Party and the government paid great attention to people’s livelihood and safety in production. Safety measures have been continuously strengthened, safety policies have been continuously introduced, and responsibility has been investigated in one step, making every effort to promote Liuyang fireworks production to a healthy development path.
In fact, it is understandable that we attach importance to safety and protect the bad environment, but when it comes to "danger", it is also inappropriate to ban it. There are many industries in the world today, such as electric power, construction, chemical industry, mining and so on, which belong to "high-risk industries". Accidents often occur, but none of them stop working normally. Traffic accidents can’t ban people from riding cars, and mine accidents can’t stop mining. Similarly, it is unwise for me to ban fireworks production because of accidents. As a part of Chinese excellent traditional culture, with the improvement of people’s living standards and the increase of festival activities, the art of fireworks has attracted more and more public attention and attention. The fireworks industry has provided more employment for Liuyang people and created more joy for the people of the world.
In addition to safe production, the environmental pollution caused by fireworks is also a new problem that people often mention in recent years, but in fact, the pollution caused by fireworks is almost insignificant compared with chemical pollution and automobile exhaust. According to the monitoring data of Hunan Environmental Monitoring Center Station, among the air quality indicators in Liuyang in the first half of 2020, six pollutants, namely PM2.5, PM10, sulfur dioxide, nitrogen dioxide, carbon monoxide and ozone, all reached the standard, and the excellent rate of air quality reached 100%. As the main producing area of fireworks, Liuyang’s environmental quality is even better than other parts of the country, which further demonstrates the unscientific nature of excessively restricting the natural development of fireworks industry.
In the past, the fireworks culture was closely linked with the China New Year culture. The rich will set off fireworks in the new year; And the poor will buy at least a few firecrackers for the festive atmosphere of the New Year. Nowadays, with the restrictions on fireworks and firecrackers in some areas, the correlation between fireworks culture and China New Year culture has been weakened, which is also a kind of destruction to the integrity of Chinese culture.
In a word, although there are many problems in Liuyang fireworks industry, we must treat the problems scientifically and rationally, which is the only way to make the fireworks industry develop healthily.
Third, the establishment of brand effect
After the reform and opening up, the planned economy led by the government has gradually changed to a commodity economy led by the market. The market competition has suddenly intensified, and Liuyang needs to re-attach importance to the establishment of the brand effect of "Liuyang Fireworks". In addition to improving production techniques to make colors brighter, shapes more diverse, safety more reliable, and packaging more exquisite, Liuyang also founded the "Liuyang International Fireworks Festival in China" with great innovative consciousness. Fireworks Festival not only displays fireworks, but also shows the latest achievements of Liuyang fireworks research and development to all walks of life at home and abroad, and also carries out a series of activities such as exhibitions, economic and trade negotiations, and cultural performances.
At the same time, it also organizes enterprises to set up commercial guilds according to market requirements, and sizes up the situation to carry out listing activities. On July 31, 2001, the fireworks stock issued by Liuyang Fireworks Co., Ltd. was officially listed on the Shanghai Stock Exchange. In 2002, the city produced 17.63 million boxes of fireworks, with an output value of 2.258 billion yuan. From 1988 to 2004, the output of Liuyang fireworks increased from 1,571,338 boxes to 12,115,000 boxes, an increase of 14.8 times. Fireworks have really become the pillar industry of Liuyang. [18]
Fourth, the impact on the lives of local people
Since ancient times, the rise and fall of fireworks industry has profoundly affected the people of Liuyang. Today, the fireworks industry is bigger and stronger, and its influence on local people is further deepened.
Fireworks production is a labor-intensive industry, with simple auxiliary processes and low requirements for academic qualifications and intelligence. As long as you study hard, it is easy to learn. So that it can be operated from the elderly to the children, which is an excellent way for Liuyang to solve the rural surplus labor force.
According to Liuyang County Records, in 1987, the number of employees in fireworks enterprises and their affiliated industries in the county reached 400,000, accounting for 31.66% of the total population in the same year.
The influence of fireworks industry on Liuyang people is not only reflected in the percentage of its employees in the total population of the county, but also the reasons for this percentage and the influence of this phenomenon. A proportion can show a macro impact, such as whether Liuyang’s industry is too single, etc. But for individuals in history, what we should think about is: why did everyone go to the fireworks factory to work? For this kind of phenomenon, the production and life of people near my home may give an answer.
On the street in my hometown, every household has a field, but every household has people working in the fireworks factory. I once went to see my father at the Fireworks Factory and learned about the wage level of the fireworks factory workers. A skilled and diligent fireworks factory worker can earn 200 yuan RMB one day under the condition of "three shifts", which is more than 70,000 yuan a year.
Liuyang has fully promoted the development of other industries in recent years, and the rapid development of high-tech industries in Liuyang Park is a typical example. It should be noted that although the development of fireworks industry may bring some unfavorable factors to the local area, on the whole, the advantages should outweigh the disadvantages. This can be exemplified by the increasing income and gradually happy life of Liuyang people.

Just now, outside the window came the sound of enterprises trying to put fireworks on display. In history, this bright voice has sounded on this land countless times, and it has faced crises and survived many times. Under the influence of environmental protection and COVID-19 epidemic, Liuyang Fireworks seems to have reached a historical intersection again. How to make enterprises survive and develop in this situation has become the biggest problem that fireworks entrepreneurs need to think about, and it is also the biggest problem faced by fireworks workers. The whole Liuyang Fireworks industry is looking for a way out.
This may be the "darkest moment" of this industry. However, Liuyang fireworks industry has a long historical tradition and splendid cultural heritage, which is the source of its endless life and the fundamental help to help it tide over the difficulties. I hope and have reason to hope that Liuyang fireworks industry will get better and better!

Well done! National sauna map released to see who is the first steaming in the north and south of the Yangtze River.

China Weather Network News In recent two days, the largest and longest-lasting high-temperature weather in China has been "online" this year. The north and the south have started the high-temperature mode together, and the north is roasting and the south is steaming. Both netizens in the north and the south have shouted heat, and even sent out a soul torture about who is more unbearable. So who is hotter, dry, hot and humid? China Weather Netcom counted out the national sauna map and the steaming list of provincial-level cities with big data to see who has the highest thermal value.
Hot, dry and sultry, big PK sauna day wins by rolling
China Weather launched a poll on "Which is more uncomfortable, dry or stuffy" in Weibo. The results showed that 32,000 netizens chose "sultry sauna", accounting for 80%, while only about 20% chose "sunny barbecue". The "sultry sauna" can be described as a rolling victory.
Why is sauna day more collapsed?
It is also hot, why do people think that "sultry" is more devastating than "dry heat"? What is the weather like in sauna days?
Zhang Feng, deputy chief forecaster of the National Meteorological Center, said that according to the People’s Republic of China (PRC) meteorological industry standard "Sauna Weather Grade" released on May 10th this year, sauna days refer to the sultry weather with high temperature, high humidity and low wind speed, which gives people a feeling like a sauna.
Zhang Feng explained that the reason why sauna days are so uncomfortable is mainly because the heat in the human body cannot be spread out in time. In hot weather, the human body cools down by sweating, because sweat evaporates and absorbs heat, taking away the body’s heat. When the humidity of the surrounding environment is high, the evaporation speed of sweat will be greatly reduced, while the small wind speed will lead to the low flow speed of air, which will keep the high humidity environment around the skin and is even more unfavorable for evaporation.
Based on the same reason above, people’s feeling of temperature will be influenced by relative humidity, wind and other factors. When the temperature reaches a certain height, the higher the humidity, the higher the somatosensory temperature under the same temperature conditions.
NOAA heat index also shows that when the temperature is higher than a certain value, at the same temperature, the greater the relative humidity, the more obvious the increase of somatosensory temperature. When the temperature is 32℃ and the relative humidity reaches 60%, the somatosensory temperature can reach 37℃, and it will increase with the increase of humidity, and even reach 49℃ when the relative humidity reaches 90%.
Theoretically speaking, the somatosensory temperature caused by 37℃ combined with 28% relative humidity ≈ the somatosensory temperature caused by 32℃ combined with 60% relative humidity, so at the same temperature, the somatosensory temperature in hot and humid weather will be higher. However, the somatosensory temperature will also be affected by factors such as wind, and everyone’s perception is also different, so it still varies from person to person.
The map of sauna days in China is released, and "every minute must be steamed" in Guangdong and Hainan.
China Weather Network counted the big data from 1991 to 2020, and found that Hainan, Guangdong, Fujian and other places in China are the most frequent areas for sauna days, with an average annual number of sauna days exceeding 45 days, which is the place where every minute must be steamed. There are also many sultry days in Guangxi, Zhejiang, Jiangxi, Hunan, Hubei, eastern Henan and other places, with an average of more than 30 days per year, which can be described as "thriving"; In northern Hubei, Jiangsu, Anhui, southern Yunnan, Hebei, southern Beijing, southwestern Shaanxi and other places, the number of sauna days is 15-29 days, which can be described as "steaming upstream".
Sauna days in Heilongjiang, Jilin, Liaoning, northern Beijing, Shanxi, Gansu, Ningxia, northern Xinjiang and Guizhou belong to the level of "occasional dew steaming capacity", with an average annual number of days less than 15 days, and some areas are less than 5 days; The number of sauna days in Tibet, Qinghai, western Sichuan, northwestern Gansu, northern Inner Mongolia and southern Xinjiang in China is 0, which is a real "steaming-free" place.
High temperature ≠ sauna days Haikou Guangzhou leads the steaming list of provincial capital cities in China.
Sauna day is not equal to high temperature. When the temperature reaches 35℃, the high temperature can be judged. In contrast, sauna day has a slightly lower limit on temperature, but it needs to comprehensively consider three factors: temperature, relative humidity and wind speed. There are not necessarily many sauna days in areas with frequent high temperatures in China. For example, Guangdong and other places belong to "high temperatures don’t often exist, but sauna days often come". Take Guangzhou as an example, the average annual high temperature days are only 20 days, but the sauna days are as high as 45 days, which is twice as many as the high temperature days.
Statistics show that the provincial-level cities with the largest annual average sauna days are mainly concentrated in South China and the Yangtze River basin. Haikou and Guangzhou have an average annual sauna days of more than 45 days, and Wuhan, Nanchang, Shanghai, Chongqing, Changsha and Hangzhou generally have an average annual sauna days of more than 20 days.
In addition, "sauna days" is not a specific "product" in the south, and there are not many sauna days in North China, Huanghuai and other places. The average annual sauna days in Zhengzhou, Shijiazhuang, Tianjin and Beijing are all over 15 days.
Keep in mind "three more and two less" and deal with sauna days skillfully
In sauna days, people are more prone to heatstroke because of high temperature and high humidity. Moreover, in sultry environment, the human body consumes a lot, and sleep is easy to be bad. In addition, turning on the air conditioner and blowing the fan can easily lead to colds and colds. Everyone should keep in mind the five points of "three more and two less" and deal with sauna days skillfully.
Ventilation: Keep the surrounding environment naturally ventilated. People should not stay in the air-conditioned environment for too long. Open the windows regularly to let in fresh outdoor air.
Drink more water: be sure to drink more water, and don’t drink it when you are thirsty, especially if you sweat a lot, drink a little light salt water.
Take more rest: pay attention to keep enough sleep, live and work regularly, and enhance immunity.
Go out less: avoid going out at the highest temperature of 10-16 o’clock. If you have to go out, take protective measures and avoid being exposed to the sun for a long time.
Less delay: In case of dizziness, nausea, chest tightness and other early symptoms of heatstroke, you should rest immediately and drink cold water to cool down. If the condition is serious, you should go to the hospital immediately.

The fertility, violence, and workplace behind the "half the sky" of the global women’s living conditions …

BEIJING, Oct. 22 (Xinhuanet)-The United Nations Department of Economic and Social Affairs released the report "World Women in 2020: Trends and Data" on the 20th, analyzing the global gender equality situation from the fields of health, education, workplace and violence against women. The report points out that women take on a lot of unpaid housework and nursing work, which limits their economic potential. At the same time, the epidemic in COVID-19 may aggravate the impact on women’s work and livelihood.

On the same day, UN Under-Secretary-General Liu Zhenmin pointed out that countries should redouble their efforts to empower women and girls in order to bridge the data gap in key areas of gender equality.

At present, the real living environment of many women around the world may be seen from this report of the United Nations.
