Xinhua News Agency, Abidjan, September 9 (Reporter Zheng Yangzi) News from Niamey: Since the 2nd of this month, thousands of people from Niger have gathered in the Escaderil Circular Square in front of the French army station in the south of Niamey, the capital, shouting the slogan "the French leaves Niger" and demanding that the French troops leave Niger unconditionally.

　　Since the coup in Niger on July 26th, the Economic Community of West African States (ECOWAS) has repeatedly stated that "the possibility of military intervention in Niger is not ruled out". The French side said that if the ECOWAS decides to take military action against Niger in the future, France will support it.

　　"The purpose of our demonstration is to show France the determination of the Niger people to defend national sovereignty." A Niger who took part in the demonstration said that they renamed Escadril Circular Square "Resistance Square".

　　Bubacar Abdou, a member of the Association of Retired Ambassadors and Consuls General of Niger who participated in the demonstration, said that the coup authorities have not recognized the previous military cooperation agreement between Niger and France, but up to now, 1,500 French soldiers are still stationed in the capital of Niger. "The people of Niger cannot accept such a powerful act."

　　Niger was once a French colony, and France did not recognize the coup authorities in Niger. It is also reported that the French military is negotiating with the coup authorities in Niger to seek to "withdraw some military resources" from Niger. The coup authorities in Niger said that the "contact" with the French side is going on regarding the withdrawal of French troops.

　　According to French media reports, people’s dissatisfaction with France in Niger appeared before the coup. Since last year, Nigerian non-governmental organizations have organized many demonstrations demanding the withdrawal of French troops.

　　Beijing, 25 June (Reporter Yang Zhaokui) Today, the reporter found that this year’s Dragon Boat Festival holiday coincides with the end of the college entrance examination, and the superposition of parent-child tour, graduation tour and summer vacation has driven the tourism industry to further recover.

　　Tuniu data shows that during the Dragon Boat Festival holiday this year, users’ enthusiasm for traveling is high, and the tourism market has been rekindled. Among them, the parent-child group is one of the main groups traveling in the Dragon Boat Festival, accounting for 41% of the trips. According to the data of Ma Honeycomb, the average heat increase of parent-child tour in Ma Honeycomb Station is 135%.

　　In terms of graduation tour, flying pig data shows that this year’s Dragon Boat Festival holiday is catching up with the college entrance examination, and some schools are starting to have summer holidays. The scale of travel users of college entrance examination students and college students has increased significantly, and the booking volume of parent-child and research tour products has increased by more than three times year-on-year.

　　During the Dragon Boat Festival holiday this year, many places in the north continued to experience high temperatures. According to the data of the US Mission and the public comments, in the high temperature, summer vacation and cooling have become the key words of travel. The tourism popularity of northern coastal cities such as Qingdao, Weihai, Qinhuangdao and Dalian has increased significantly.

　　The travel data of the same journey shows that during the Dragon Boat Festival holiday, the booking volume of hotels around domestic concerts and music festivals increased by more than 300% year-on-year.

　　"The Dragon Boat Festival is often the weather vane of the summer tourism market. Judging from the fiery degree of more than 100 million trips this year, the next summer market is expected to usher in a new round of tourism peaks, and tourism will also enter a new stage of structural recovery." Feng Rao, dean of the Ma Honeycomb Tourism Research Institute, said.

This year’s Father’s Day is June 18th, which coincides with the promotion of June 18th. For many people, the best way to express "love" should be that buy buy bought it, and so does his love for his father. It is reported that 64.4% of female netizens interviewed are willing to buy Yan value products as gifts for men, which pushes the "male beauty economy" to the focus of this year’s 618.

Recently, the official list of Tmall 618 shows that four hours before the pre-sale of Tmall 618, brands such as L ‘Oré al Men, biotherm, Gillette and Ximuyuan were on the TOP10 of Tmall’s men’s care industry list, among which Ximuyuan ranked first among domestic brands.

Four hours before the pre-sale of 618, Ximuyuan Aurora Black Spruce men’s specialized skin care suit won the first domestic product in the men’s care industry.

As of June 14th, Ximuyuan’s Aurora Black Spruce Men’s Skincare Series, which has been on the market for only six months, surpassed Kiehl’s and L ‘Oreal in the hot list of Tmall’s "Men’s Gift Box" and "Men’s Skin Care Set", ranking first in the men’s skin care industry. As early as more than one month after the launch of Aurora Black Spruce men’s skincare series, Ximuyuan has surpassed L ‘Oré al and biotherm, and also surpassed some cutting-edge brands specializing in men’s products, ranking first in the men’s skincare list.

This is the development trend that the domestic male skin care market has not had in the past ten years, and it also indicates the emergence of new match points. The strong breakthrough of Ximuyuan is closely related to its accurate insight into the underlying logic of men’s skin care track and the scientific and technological strength of intensive cultivation.

Ximuyuan Aurora Black Spruce Men’s Skin Care Series ranks first in Tmall 618 "Men’s Gift Box" and "Men’s Skin Care Set"

On the one hand, Ximuyuan’s product development is based on keen market insight: on the core demand, through in-depth investigation and study of consumers, Ximuyuan found that men tend to be "rational" and "effective" in product selection, and solving skin pain points such as acne, oily skin and redness sensitivity is the main motivation for choosing skin care products. However, in the existing categories on the market, there is a big supply gap for men’s basic nursing categories such as water, milk and cream, which leads some male consumers to flow to "sexless" products or women’s products. At the same time, male consumers are different from female consumers in skin care habits. They generally want to simplify skin care, make quick purchase decisions, and prefer fast and convenient shopping experience.

On the other hand, the continuous construction of scientific research moat has laid a good foundation for a series of explosive products of Ximuyuan. Since its establishment four years ago, Ximuyuan has set up its own laboratory Simpcare Lab, and has also carried out in-depth cooperation with first-class scientific research institutions such as the National Engineering Research Center for Genetically Engineered Drugs, Sanli Huiping Testing Technology Center of Beijing Technology and Business University, and Tsinghua University Pearl River Delta Research Institute, creating a five-dimensional scientific research model, opening up the path from science to clinic, satisfying consumers’ needs with "exquisite formula", polishing product strength and providing consumers with a safe, effective and pleasant product experience.

The research and development cycle of international big-name new products is mostly 3-5 years, but the average development cycle of domestic beauty industry is only 3-4 months, and Ximuyuan’s research and development of men’s series products started as early as 3 years ago, and it took 3 years to launch at the end of 2022, which far exceeded the average development cycle of beauty and skin care industry.

Inhibition of 5&alpha in skin based on the extract of black spruce with aurora; Reductase and reduce excessive sebum secretion, Ximuyuan R&D team added a patented ingredient "MATMARINE" imported from Spain and Simpcare 1609 specially developed by Ximuyuan to the product: the former can refine pores and smooth skin by reducing sebaceous gland cell differentiation; The latter can relieve irritation and solve sensitive problems such as redness, heat, itching and pain by slowing down the excessive activation of TRPV-1 in the nerve.

In order to meet the needs of men’s minimalist skin care to a greater extent, Ximuyuan has also built a [6: 3: 1] cleaning system specially developed for men, which can dredge pores and take away dirt, and at the same time, use a simplified amino acid to balance the formula, prevent the skin from being tight and false red due to excessive cleaning, and solve men’s skin problems in one step.

Relying on the long-term layout of scientific research technology and channel resources, Ximuyuan has become a leader in men’s skin care track in just six months by understanding the needs of men’s consumers and making up the market gap, and achieved "overtaking in corners".

It is reported that the market for men’s grooming has reached nearly 10 billion. According to the White Paper on Tmall Men’s Care in 2023, the market for men’s skin care in China is still expanding, and it is expected to reach more than 20 billion yuan by 2026. With the change of social concept and aesthetic consciousness, more men began to pay attention to their appearance image, and more women began to pay attention to men’s needs in this field, which jointly promoted the cultivation of this market. It is foreseeable that the "other economy" will continue to release its growth potential in the next few years. In this case, it is necessary to have a deep insight into consumer demand, continuously polish product strength, and do a good job in market education and product science popularization at the corresponding stage, and Ximuyuan is obviously one of the strong competitors.

　　Source: Ministry of Agriculture and Rural Affairs, etc.

　　In April 2022, General Secretary of the Supreme Leader visited Hainan and came to the "brain" of Nanfan Scientific and Research Breeding Base — — Sanya yazhouwan seed laboratory. The general secretary said: "Only by grasping the seeds of China with your own hands can you stabilize China’s rice bowl and achieve food security."

　　Nanfan, a large number of agricultural workers’ repeated migration journey. From September every year to May the following year, they come to Hainan from all over the world to take advantage of the unique tropical climate conditions here to carry out a series of scientific research activities such as crop seed breeding, hence the name "Southern Breeding".

　　At the moment, it is the season of the south. Let’s follow a rice seed to observe how it will grow from creating materials to breeding and seed production.

　　Sampling — — Sanya, Hainan

　　It took 10 years to produce a good variety.

　　Some have just been sown or seedlings, some are heading green, and some are golden to be harvested — — Walking into the Nanfan Base in Sanya, Zhongzhong Group, you can get a glimpse of rice at all growth stages.

　　"The advantage of Hainan is that there are abundant light and temperature resources, and we will sow here every one or two months." Shi Yitao, assistant of rice breeding in Zhongzhong Group, is a good way in the crop field. "Farmers will, we will;" Farmers won’t, and we understand. "

　　For a year, he guarded the experimental field like a child, and his broad face was tanned. "Water carefully every day to observe, prevent snails, birds and mice. I want every seedling to sprout and thrive. " Shi Yitao said.

　　It’s windy, rainy and sunny, which is a summary of the local climate by Nanfan people.

　　Sowing in the hot sun, sometimes, you have to hide from the rain four or five times for half a day. Whenever it rains, Shi Yitao is on tenterhooks: when the seedlings were young, he was afraid of the heavy rain and washed up the nutrient soil and washed away the seedlings; The rice is a little longer, catching up with the typhoon. The water in the field is more than 60 centimeters, leaving an ear on the water surface. It is raining against the wind and drowning again and again. "Danger is not afraid, and nothing is important to keep the seedlings."

　　In the corner of the experimental field, the iron fence was deeply embedded in the soil, and a small rice field was specially taken care of. "Specially rat-proof, afraid of gnawing materials." Shi Yitao gently pulled open the iron door and walked through a ridge, and the green and tall seedlings came into view.

　　"these are breeding materials R1607 with low cadmium gene introduced, which is already in tillering stage." Shi Yitao bowed down and took off a piece of leaf with tweezers, about 1 cm long, and carefully put it in a deep hole plate. "I hope it will be successful in one sampling."

　　From the summer of 2021 to now, this batch of materials has been planted in Hainan for three consecutive seasons, plus one season in Hainan in winter of 2020 and one season in Hubei in early 2021. It has been crossing, backcrossing and selfing for more than two years, and it has been five generations. Preliminary laboratory data show that the genetic traits of low cadmium gene have already appeared in future generations.

　　"If there is no problem with the re-inspection data, after maturity, you can select a trial plant with the best growth and the best laboratory genetic data from these 2000 strains." Shi Yitao said.

　　Just pick one plant, will it be too few?

　　"You don’t look down upon it, the seed setting rate is very high, one plant also has one or two thousand grains, and the ear of rice is half an arm long. This is also the reason why the rice variety Youyou 607 is favored by the market. "

　　"If you compare Quanyou 607 to an excellent ‘ Baby ’ Then R1607 is like an excellent ‘ Father ’ 。” Zhou Hua, director of rice testing of Zhongzhong Group, said that R1607 not only aggregated 8 rice blast resistance genes and 3 lodging resistance genes, but also aggregated 17 genes of sheath blight resistance, cold tolerance, flood tolerance, nitrogen efficiency and yield. Now, after introducing the low cadmium gene, even if rice is planted in fields with excessive cadmium content, it is low in adsorption or insensitive to cadmium.

　　How long does it take to breed a fine variety like Quanyou 607?

　　"It took 10 years from breeding to variety approval!" Zheng Ruifeng, the head of the R&D team of Quanyou 607 and the director of rice breeding of Zhongzhong Group, said that the creation of new materials is very uncertain. "There have been 52 cross combinations, and finally only R1607 was bred."

　　The R&D team will then introduce genes against bacterial blight, rice planthopper and fragrance, etc., and constantly upgrade and transform R1607 to become an all-around champion, so that the "baby" born will be better.

　　What is the most difficult thing in breeding?

　　Zheng Ruifeng replied in this way: if the varieties that show "leverage" are planted in other places for trial planting, some unexpected situations may occur, such as not resisting high temperature, low temperature, lodging, a certain disease, or a certain climate. Sensitive, "this will make all previous efforts and investments zero."

　　The early research and development is difficult, but the heart is still not hanging. Once it enters large-scale production, the strings in the heart will be tightly stretched. The bigger the promotion area, the more worried it is. "If farmers fail to harvest food, we will have trouble sleeping, and we will be relieved when we harvest it." Zheng Ruifeng said.

　　Detection — — Wuhan, Hubei

　　Breeding experts wear "gene glasses"

　　In Wuhan, Hubei Province, the genotyping laboratory of the Life Science and Technology Center of China Seed Group, the low cadmium sample sent from Sanya base, finally ushered in the key experimental link — — DNA genetic material was extracted and analyzed.

　　Zhang Xiaobo, the head of the laboratory, tapped the button, and the shaker, centrifuge and PCR instrument ran one after another. The data showed that the recovery rate of differential loci was 88.7%, and the recovery rate of whole genome reached 97.5%.

　　What do these data mean? "This shows that the low cadmium gene has indeed been stably passed on to the offspring of R1607. After the upgraded version of R1607 matures, a new trial production process can be started." Zhang Xiaobo explained.

　　"In the breeding process, the laboratory and the experimental field are closely linked." Ye Rongjian, deputy director of the Technology Platform Department of the Science and Technology Center of Zhongzhong Group, said that the genetic performance after the introduction of low cadmium gene is difficult to observe by experience. "Is cadmium adsorbed into rice seeds? The naked eye can’t see it at all."

　　"When R1607 was first created, molecular biological breeding technology was just beginning, and we took the path of traditional cross breeding combined with molecular breeding assisted selection. Nowadays, molecular marker detection and genome breeding technology have become very common, which is like wearing a pair of glasses that can see through the function of genes for breeding experts. " Zheng Ruifeng said that intelligent breeding in the future, relying on artificial intelligence, big data and biotechnology, will be more efficient and accurate.

　　Of course, the powerful function of this pair of glasses depends on the breakthrough of basic research. "The reason why the introduction of low cadmium gene has achieved results for more than two years is because the functional sequence of low cadmium gene is very clear." According to Ye Rongjian, there are about 50,000 genes predicted in rice. At present, about 4,000 genes are cloned and their functions are clear. It may take many years for a gene to know its functions, and the road ahead is still very long.

　　"The laboratory not only undertakes the task of detection and analysis, but also explores the mystery of genes." Nie Dongming, the seed administrator, pushed open the heavy security door, and a germplasm resource bank with more than 100,000 rice materials was presented. Here, at the temperature of 4 degrees Celsius, the seeds enter a dormant state and can be safely stored for 5-mdash; Ten years.

　　Zhou Hua said that the germplasm resource bank is a treasure house for creating breeding materials. At that time, Academician Yuan Longping discovered the special material of wild rice sterile plant "Wild Abortion" in Sanya, and achieved the breakthrough of hybrid rice breeding.

　　R1607′ s breakthrough in rice blast resistance is also due to the germplasm resource bank. "At that time, we were making a breakthrough in the technology against rice blast. I heard that the Chinese Academy of Sciences discovered a gene with strong resistance, but breeding experts did not have this material at hand. We went to the germplasm resource library to search and found the original material. " Zheng Ruifeng introduced that this peasant variety was used to cross and backcross with indica rice varieties, and a series of materials containing rice blast resistance genes were bred.

　　"If things in nature are lost, you may not find them when you want to use them in the future. The importance of the germplasm resource bank is now more and more deeply understood. " Zheng Ruifeng said that it is a source protection when its value is not clear and the advantages of germplasm resources are not tapped.

　　Zhou Hua introduced that China Seed Group and Yazhouwan Seed Laboratory jointly issued a list for the first-class scientific research institutes and universities in China, and Industry-University-Research jointly integrated gene resources, and there were more than 10 topics in the field of rice alone. In addition to further cooperative research on low cadmium genes, there are also cooperation in herbicide resistance and rice false smut resistance. "The goal is to make excellent rice varieties full of treasures."

　　Seed production — — Hainan dongfang

　　One mu of seed production can be used for more than 100 mu of fields.

　　"Yanmei, throw me the seedling!" "Good, then!" Fu Yanmei didn’t lift her head. A bunch of tender rice seedlings came out and flew over eight or nine women who worked hard, drawing an arc over the paddy field and accurately "delivering" it to Zeng Yabei.

　　On February 3rd, gancheng town, Dongfang City, Hainan Province, after the Spring Festival, seed production and rice transplanting have been busy for more than a week. The villagers cooperated skillfully, transplanting rice in the field, and there were bursts of laughter from time to time.

　　Such busy and cheerful scenes often appear in the process of seed production. In the whole seed production process, the most attractive thing is heading and flowering, which is also called catching powder.

　　At the end of October last year, in this field, the reporter witnessed a scene of catching powder. The sky clears up, the temperature rises, the male parent and female parent materials in the rice field bloom and spit, and pale yellow flowers are dotted with light green ears of rice swaying gently in the breeze. A 40-meter-long rope hangs in an arc on the ear of rice. The two workers each held one end and walked quickly forward in parallel. Where the rope passed, the ears of rice touched, the stamens trembled, the pollen floated to the pistil of the female parent, and suddenly a pale yellow powder fog was stirred in the field.

　　Wang Shiming, general manager of Hainan Nongle Nanfan Technology Co., Ltd. said: "Breeding is to bring a bag of seeds and carry a bag of seeds back. Seed production is different. One acre of seed production can be used for more than 100 acres of fields. "

　　There are many seed production processes, so it is necessary to plant seeds in reverse order to let parents meet this flowering period. For example, it takes 100 days for the male parent of Quanyou 607 to plant and 80 days for the female parent, so the male parent should plant 20 days in advance; After that, we constantly observe the leaf period, analyze the flowering period, and sometimes adjust it through water and fertilizer to ensure that the flowering period meets.

　　"Artificial powder driving can improve the seed setting rate of hybrid rice." Wang Shiming introduced that many years ago, there were as many as 100,000 people in Hainan from Pingxiang City, Jiangxi Province. In recent years, the country has revitalized the seed industry, and Pingxiang has also introduced measures such as subsidies for large seed producers and subsidies for grain production. Encouraged by this, many Jiangxi farmers who have produced seeds in Hainan have returned to their hometowns for development.

　　"Raising seedlings, transplanting seedlings, heading and pollination, harvesting and drying seeds, selecting seeds and packaging, I can play when I am young." Wang Shiming has been following his parents to Hainan for more than 20 years. His skin is tanned and he speaks slowly. In 2022, Dongfang City, where he lives, was recognized as a national seed production county, with a million mu of fertile land in Thanksgiving Plain. "Winter seed production starts at the end of December every year, and the seeds are harvested in April and May of the following year, which is just the time for the middle and lower reaches of the Yangtze River."

　　Affected by rising land rent and labor costs, Hainan rice seed production has been moving westward, from Sanya to Ledong Li Autonomous County, and then to Dongfang City. "The average annual land circulation per mu in the East is 1,300 yuan, but it has already exceeded 3,500 yuan in Sanya." Wang Shiming said.

　　In the middle and late September of 2022, Wen Mincao, deputy manager of the production department of Zhongzhong Agricultural Science and Technology Company, received an urgent task. When the seed production area of Quanyou 607 Hainan suddenly increased from the original six or seven thousand mu to more than 20,000 mu, his head was buzzing. Where can he find the producer and production base?

　　The Chinese company implements the order system and gives plans to manufacturers and professional teams all over the country every year. However, the farming season in the mainland has passed in winter and it is difficult to produce seeds; Although Hainan can produce seeds, it is also the winter melon and vegetable season, with less open space, high land rent and early seed delivery time. At one time, it is a bit intense to "grab the base".

　　Thanks to Wang Shiming’s contacts in many ways, Wenmin Cao took only one week to reach an intention on 6,000 mu of land and finally breathed a sigh of relief. "Seed production counties support the integration of production, processing, warehousing, packaging and logistics. With favorable policies, we have signed a cooperation framework for the integration of production and supply chain with local manufacturers, which can be produced locally, packaged locally and sent to the market, and can be stored locally if they are not sold out."

　　All the efforts are worthwhile.

　　In the middle and lower reaches of the Yangtze River, farmers who have tasted the sweetness have long been thinking about good seeds. In Shilou Village, Wudian Town, Zaoyang City, Hubei Province, Chen Bangguo, a large grain grower, called Qiu Yunze, a seed dealer in Wudian Town, after planting winter wheat.

　　"Good seeds are in demand! When we tried to plant Quanyou 607, it was Laoqiu who came to sell it, and he guaranteed it, saying that it was not good to compensate my output. As a result, two or three hundred kilograms of rice were added to an acre of land. I am happy to invite Laoqiu to eat! " Chen Bangguo said.

　　"In the early stage, we will build a model field display, and invite large households to go to the scene to observe the harvest and yield measurement, so that more farmers can see the comparative advantages of varieties. In the later stage, collect information about high-yield farmers, make posters, and organize seedling meetings from seedling stage to heading stage to expand influence. " Speaking of the promotion experience of good seeds, Wang Hanyong, deputy sales manager of Hubei Branch of China National Seed Group, talked endlessly.

　　The field of hope, season after season, the story of a fine variety will be told constantly.

　　Planning for this issue: Yin Xinyu, Wu Yan and Cheng Juxin

　　Core reading

　　Not long ago, the Ministry of Ecology and Environment announced the handling of the national "12369" environmental protection report in May this year, and noise pollution reports accounted for 41.4%. The impact of noise pollution on residents’ lives should not be underestimated. At the same time, noise pollution infringement cases have the characteristics of being difficult to identify causality and quantify related losses. Don’t let the noise disturb the people, but also need many efforts.

　　A few days ago, the Intermediate People’s Court of Xuzhou City, Jiangsu Province announced the second-instance judgment result of a case in which a villager turned over his new house to set off firecrackers, causing the loss of rabbit breeding next door. The discharger compensated the farmers for more than 440,000 yuan.

　　A deafening burst of firecrackers made those who set off firecrackers pay large compensation, which many people did not expect. In fact, noise pollution has troubled many people’s lives — — In the streets and alleys of cities and villages, noise pollution such as car horns, construction site sounds and square dance horns is widespread.

　　In case of noise pollution prosecution, the court ordered noise reduction and rectification.

　　The rabbit farm of Zhang, a villager in Houzhu Village, Hegou Town, xinyi city, Xuzhou, is adjacent to Cai’s house. On December 1, 2017, Cai set off firecrackers to celebrate the completion of the new house, which lasted for three or four minutes. After the deafening firecrackers, Zhang found that the rabbits raised in the farm appeared one after another, such as the abortion and death of the mother rabbit and the death of the little rabbit in the cage.

　　Zhang believes that the abnormal situation of rabbits is caused by setting off firecrackers, and Cai believes that there is no evidence. After several times of communication, the two sides failed to reach an agreement, and Zhang filed a lawsuit with the xinyi city People’s Court. The certificate submitted by Zhang shows: "December 1, 2017 — On the 13 th, 1,573 female rabbits, 10,070 rabbits and 15,000 aborted rabbits died due to firecrackers. "

　　According to the Law on the Prevention and Control of Environmental Noise Pollution, xinyi city People’s Court ruled that Cai compensated Zhang for a total loss of 440,307 yuan. After the verdict, Cai refused to accept it and appealed to the Xuzhou Intermediate People’s Court. In March this year, Xuzhou Intermediate People’s Court made a second-instance judgment, dismissed the appeal and upheld the original judgment.

　　One of the cases that have been selected into the top ten typical environmental protection cases of Jiangsu Provincial High Court is also about noise pollution.

　　"The noise on the highway is unbearable, especially at night … …” In July 2013, China Environmental Protection Federation received a report from the people in Dongbeitang Street, Xishan District, Wuxi City, reflecting that after the completion of a nearby expressway expansion project, five natural villages were polluted by traffic noise, which seriously affected the lives of some residents. Although the highway construction companies have installed sound barriers in some areas, the size and standards of sound barriers are different, and the environmental noise of some residents’ homes at night still exceeds the national standards.

　　After receiving reports from the masses, China Environmental Protection Federation filed a civil public interest lawsuit against noise pollution in Wuxi Intermediate People’s Court in March 2014, requesting that the expressway company immediately take active and comprehensive measures to control environmental noise pollution and eliminate the harm of environmental noise pollution in the villages involved.

　　In order to obtain monitoring data such as environmental noise pollution, the court entrusted the local environmental monitoring station to make a monitoring report, reflecting that the environmental noise of the five natural villages involved basically reached the standard during the day and generally exceeded the standard at night.

　　"Both sides have the willingness to mediate, and considering the reality that the expressway can’t be shut down, the court will consult relevant experts with the expressway company, propose a mediation plan for noise reduction and rectification, and reach a mediation agreement after mutual consent." Zhou Ke, the presiding judge of the case and the environmental court of Wuxi Intermediate People’s Court, introduced that the main contents include adding, heightening, extending the sound barrier, replacing the material of the sound barrier, etc. After the rectification is completed, the court entrusted noise monitoring to ensure compliance with relevant standards and not affecting residents’ lives.

　　Causality determination and loss quantification are the difficulties in noise pollution infringement cases.

　　"Noise is divided into four categories: social noise, traffic noise, enterprise noise and construction noise." Li Zongke, head of the Environmental Monitoring Corps of Nanjing Environmental Protection Bureau, said that although noise pollution is intangible, its physical and mental impact is objective.

　　Chen Ying, vice president of the Environmental Court of Jiangsu Higher People’s Court, told reporters that noise pollution has the characteristics of occasional and frequent interweaving. The identification of causality and the quantification of losses are difficult points in noise pollution infringement cases.

　　"The damage caused by noise pollution varies from person to person. The same level of noise will do relatively more harm to people with poor physique and neurasthenia; But for others, it may have little effect. It is usually difficult for the plaintiff to prove that noise may cause damage. " Chen Ying introduced that the amount of civil compensation is determined by the amount of damage, but it is also difficult to quantify the loss, which often needs to be proved by various ways and channels.

　　"Noise pollution infringement cases have their own particularity and complexity." According to Zhou Ke, noise pollution is irreversible, and once it happens, it cannot be reversed. The physical and mental health of residents who have been in a high-noise environment for a long time is bound to be affected. Therefore, for noise pollution cases, more emphasis is not on compensation for environmental pollution damage, but on taking noise reduction measures to prevent noise pollution from happening again.

　　In case of noise pollution, you can complain or sue.

　　In the case of Wuxi expressway noise disturbing people, the controversy hidden behind the case lies in what environmental noise standard should be applied to this kind of residential area.

　　Zhou Ke told the reporter that according to the 2008 Standard for Sound Environment Quality, Class I standards should be applied to sensitive areas of sound environment such as rural residential areas, while Class IV standards should be applied around traffic trunk lines such as railways and expressways. Judging from the judicial practice, there is usually a village before the expressway. According to the general logic and the principle of fairness, nearby villagers should not harm their own interests because of the public interests of the expressway, and the original Class 1 standard should not be reduced to Class 4 standard because of the expressway construction unless it is fully and reasonably compensated. However, the environmental noise standards recommended and approved by relevant departments are basically the most relaxed four standards, that is, 50 meters outside the red line of highway land is taken as the noise protection distance. This widespread phenomenon may lead to the judicial decision on the application of standards, which needs to be solved by top-level planning.

　　The reporter learned that less than 1% of noise pollution infringement cases were solved through litigation, and most of them were non-litigation channels. Chen Ying introduced that common square dances, neighborhood singing, site construction, etc., citizens often choose to make complaints and solve them through administrative law enforcement. Noise pollution caused by the operation of public facilities, such as highway noise, elevator motor noise, high-voltage line frequency conversion noise, etc., is public and persistent, and it is difficult to solve through administrative law enforcement channels, so it is more appropriate to choose litigation.

　　Li Zongke told reporters that noise pollution accounts for the majority of the complaints received by the environmental monitoring corps every year, with more than 20,000 complaints about construction noise. In recent years, noise reduction has been carried out in the local area by setting up noise barriers on the construction site and approving and controlling the source. As of May 13th this year, a total of 8020 related complaints were received, down 12.9% year-on-year. (Our reporter Yao Xueqing)

CCTV News:Employment is the biggest livelihood of the people. Recently, the State Council issued the "14th Five-Year Plan for Employment Promotion", which defined seven key tasks of China’s employment work during the 14th Five-Year Plan period, among which "improving the employment support system for key groups and enhancing employment security capacity" will become the focus of future employment work.

Since the beginning of this year, a series of policies have been issued from the central government to the local government, and key groups, including college graduates, migrant workers, retired soldiers and people out of poverty, have been regarded as the top priority of current employment.

In Henan Province, there are more than 700,000 college graduates this year, ranking first in the country. Coupled with the dual effects of epidemic and disaster, the employment situation is very severe. Shortly after Zhang Yonggang, a college student, was assigned to the street office, she gained a new identity — — Volunteers for epidemic prevention and control.

This year, in order to stabilize the employment of college students, Henan Province has once again expanded the scale of "three supports and one support", and many college students like Zhang Yong have been recruited to grass-roots posts to engage in supporting doctors, teaching and supporting agriculture. At present, the government has introduced 13 measures to solve this year’s graduates’ employment through such measures as enterprises absorbing 300,000 people, recruiting 200,000 people for policy posts, starting their own businesses and flexibly employing 150,000 people.

In Hebei, in order to ensure that college students can stay and use well at the grassroots level, the government has also launched a green card for talents, providing public rental housing and various subsidies and preferential policies.

Yuan Hongzhi, Director of Civil Service Bureau of Hebei Province:Take out 30% of the county and township job plans & mdash; 50% of the special positions recruit college graduates, and encourage and guide college graduates to make contributions at the grassroots level; In the way of examination, the township position is put forward separately, which makes the civil servants employed at the grassroots level more grounded and homesick.

For college students who have not yet achieved employment after graduation season, various places are also innovating. In Qingdao, the government set up a "public service platform for youth internship and training", which attracted more than 700 high-quality enterprises to provide internship positions for fresh college students and build a "buffer zone" for employment. Wu Xiaoshuang, who hasn’t found a job since graduation, found a trainee position through the platform last month.

At present, 12,000 college students have found internship positions since the platform was launched, and the city has granted 1.134 million yuan in employment internship subsidies to college students.

Experts pointed out that entering the third quarter is the peak period for college graduates to apply for jobs in the workplace. Since the second half of the year, with a series of measures, including encouraging small and medium-sized enterprises to absorb employment, encouraging college students to work at the grassroots level, and encouraging self-employment, the employment of college graduates will remain generally stable.

Mo Rong, Vice President of China Academy of Labor and Social Security:In the second half of the year, I think it is more important to do a good job of the measures that have been introduced. For example, for college graduates, it is necessary to put their employment and employment services after they leave school in place.

Adapted from a real event, the hero’s tenderness is touching.

　　The story of "Scared Sand" took place in 1937. Qin Jiwei, the general of our army, led a 300-man team against the enemy’s 7,000-man cavalry, and successfully broke through after defending the city for three days. This film is the first film to expose the hard-fought course of the Red Army’s West Route Army. The soldiers persisted in the struggle when the supply was extremely scarce. When they ran out of bullets, they rushed at the enemy with broadswords, and the final outcome was even more tragic. Except for the hero, all the other characters died heroically.

　　When heroes also have tenderness, the emotional portrayal of each character in the film is in place. When her sister Gui Fang was about to be captured by the enemy, first hero Qin Jiwei resolutely shot and killed the brave Red Army woman warrior in order to make her sister not be insulted. Gui Fang’s husband, Lao Han, witnessed the moment of his wife’s sacrifice, and was hit hard. First, he was depressed, and then he killed the prisoners to vent his anger without authorization. He also argued with Qin Jiwei about this matter. The feelings that they had suppressed for a long time in the war were released at this moment, which was really touching.

Eating more vegetables has always been a consistent recommendation for health and wellness.

However, from time to time, you may hear such a discussion-

"So-and-so food can’t eat! Online, it is said that this dish will cause cancer if eaten! "

"Impossible, these are all rumors. How can vegetables cause cancer?"

(Source: Network)

Seeing the tweet that "vegetables may cause cancer" in the family group, many people began to wonder if green and healthy vegetables would also hide "mines". What the hell is going on here?

This vegetable is really "possibly carcinogenic"!

As a common "mountain dish" in many areas, bracken has the title of "king of wild vegetables". Its taste is crisp and tender, and its fragrance is strong, so many people can’t help eating two more in spring.

(Source: Wikimedia Commons)

However, Pteridium aquilinum is the only vegetable with cancer-causing ability so far!

As early as 2011, Pteridium aquilinum was listed as a Class 2B carcinogen by the World Health Organization, that is, it is carcinogenic to animals and possibly to humans, but the possibility of carcinogenesis is low [1].

* Note: Pickled vegetables are also Class 2B carcinogens, but mainly because of the processing method, not the vegetables themselves.

It is found that a compound called protopterin in Pteridium aquilinum is the "culprit" that may cause cancer.

In animal experiments, feeding bracken to mice and other experimental animals may cause them to develop intestinal tumors or bladder tumors. However, there is still insufficient evidence to prove that bracken can cause cancer, so it belongs to "substances that may cause cancer in human beings" [2].

So, can’t bracken really be eaten in one bite?

In theory, there is no absolute safe dose for foods that may cause cancer, which means that no matter how much you eat, there is a cancer risk. Therefore, if you don’t eat it, you can avoid the risk of cancer. Why not?

But if you really want to eat it, there is a simple way to help you reduce the risk without eating too much bracken products.

That is, drowning!

You can boil the tender fern leaves for 15 minutes after the water is boiled, or steam the tender fern leaves for 10 ~ 12 minutes, then discard the water in the cooked tender fern leaves and cook them. This can effectively reduce protopterin and other water-soluble toxic compounds in tender fern leaves [2].

2. Broken ear root (Houttuynia cordata Thunb.) causes cancer: Don’t worry too much!

The root of auricularia auricula, that is, houttuynia cordata, is also a frequent visitor in the "cancer list" of the family group.

A popular saying is: "Houttuynia cordata contains the poison aristolochic acid, which can cause cancer if eaten!"

(Source: Network)

Let’s answer directly: basically don’t worry! There is no aristolochic acid in Houttuynia cordata Thunb, but some are aristolochic lactams.

The rumored aristolochic acid is indeed a well-known class 1 carcinogen, that is, a clear carcinogen, and aristolochic acid has a strong carcinogenic effect. A small amount of aristolochic acid may cause DNA damage, which in turn may lead to various cancers such as kidney cancer.

However, houttuynia cordata contains not aristolochic acid, but aristolochic lactam.

Aristolochiam is a general term for a large class of compounds, and five kinds of Aristolochiam contained in Houttuynia cordata Thunb are not toxic [3]. At present, only in vitro cell experiments have found that Houttuynia cordata extract contains toxic substances and has hepatocyte toxicity [4].

Generally speaking, the evidence that Houttuynia cordata Thunb is toxic is very limited. So, basically don’t worry, it’s ok to eat something to relieve your craving in the season. Houttuynia cordata Thunb. has always been a frequent visitor to the table of the people in the three southwestern provinces!

3. Cucumber vegetables such as zucchini and bergamot can cause cancer?

Dian Dian said that it is necessary to avenge the rumored pumpkin, fingered citron and other melon vegetables!

Rumor has it that frying these melons and vegetables will produce acrylamide, a class 2A carcinogen (which may cause cancer to the human body and has a high possibility of cancer).

(source: soogif)

In fact, as long as foods containing carbohydrates and amino acids, such as potatoes, bread, coffee, etc., are cooked at a high temperature above 120℃, it is easy to have a "Maillard reaction".

This reaction can make food yellow and brown, release attractive aroma, but also produce acrylamide.

Therefore, the key point is that the main reason for acrylamide production in melon vegetables is "stir-frying", that is, high-temperature cooking! It is a bit unfair to let squash and other melon vegetables "carry the pot".

After all, acrylamide is more common in fried, baked and puffed foods. To avoid risks, we should eat less of these foods, and at the same time, when cooking, we should pay attention to the temperature, try to choose steaming, boiling and stir-frying, and seldom use high-temperature cooking methods such as frying and frying.

4. Cucumber "flowering" will cause cancer: don’t worry!

It is rumored that the cucumbers with thorns in the top flowers are all hormonal, which will not only cause precocious puberty, but also cause cancer.

In fact, the truth is that the top flowering cucumber may be the result of natural growth, or it may be that the plant hormone chlorfenuron was used when the cucumber bloomed.

Both of them are safe! Cucumber picked early is easy to blossom at the top, but as a plant hormone, chlorfenuron is only useful for plants, has no effect on animals, and will not cause toxicity and cancer to human body. Moreover, the general dosage is very small. If excessive hormones are used, cucumbers are prone to bitterness, hollowness, deformity and even decay.

Everyone has learned a lot about the rumors that vegetables are carcinogenic, but do you know that many vegetables are not carcinogenic but bring their own "toxins"?

However, don’t worry, you can "detoxify" with one move!

1. Fresh day lily: It contains a substance called "colchicine", which is strongly irritating to the gastrointestinal tract and can lead to symptoms such as nausea, vomiting and diarrhea. However, colchicine is easily soluble in water and not resistant to high temperature. After blanching and drying in the sun, the toxin can be basically removed.

2. Beans: It contains a lot of saponins, labyrinthine, hemagglutinin and protease inhibitors. If it is not cooked, it is harmful to human body, which can destroy red blood cells and cause irritation to gastrointestinal mucosa!

It needs to be boiled for more than 15 minutes, so that the beans are fully cooked, lose their original bright green color, and taste tasteless and bitter, and the toxin can be destroyed [5].

3. Spinach, amaranth, bitter gourd and other vegetables with bitter taste: These vegetables taste a little astringent and have a high oxalic acid content. Eating in large quantities will stimulate gastrointestinal mucosa, and oxalic acid can also combine with calcium to form insoluble "calcium oxalate precipitate", which will affect the absorption of calcium by human body or form urinary calculi. Eat properly, or blanch before cooking, and you can rest assured!

Having said so many rumors about vegetables, I believe everyone already knows that most vegetables are still green and healthy representatives. As long as they are done properly, they are all good choices at our table!

But in fact, there may be "carcinogenic poisons" hidden on our dining table!

The following four kinds of food, we really need to be vigilant, don’t eat less:

1. Processed meat:

Refers to the meat that has been smoked, salted, air-dried or other flavors that are conducive to preservation, such as dried meat, ham, bacon, etc. At present, processed meat has been "honored" as a class 1 carcinogen!

2. Chinese salted fish:

When making, it is salted and then air-dried, and a large number of nitroso compounds will be generated in the process, which belongs to Class 2A carcinogens! At present, there is sufficient evidence to suggest that Chinese salted fish will increase the risk of nasopharyngeal carcinoma.

3. Betel nut:

Recognized as a class 1 carcinogen, it is also addictive! Chewing betel nut often will damage oral mucosa and cause abnormal cell proliferation. In addition, betel nut contains a variety of alkaloids, which will promote the death of epithelial cells and greatly increase the risk of oral cancer! [6]

4. Alcohol:

Needless to say, a proper class 1 carcinogen. There is no safe intake of alcohol. A large-scale study in The Lancet shows that any amount of alcohol will be harmful to health [7]!

Therefore, as long as we eat correctly, most vegetables are healthy, and eating more vegetables in moderation is beneficial to our health. As for "carcinogenic food", we should try to eat as little as possible and keep our mouths shut.

Children of Jianghu

1905 movie network news　Fans who are familiar with Jia Zhangke’s works know that disco elements will appear in his films from "Platform", and this time’s "Jianghu Children" is no exception. Today, the film released a set of "retro disco" stills, showing the disco trend in the film in 2000. Jia Zhangke, the screenwriter and director of the film, also revealed in the interview that he was a disco culture lover when he was young.

In the newly exposed stills, Zhao Tao (played by Qiaoqiao) and Liao Fan (played by Brother Bin) are incarnated as disco youths, dancing to their hearts’ content and releasing themselves in the disco. Zhao Tao was dressed in a trendy outfit, dancing in the middle of the dance floor, showing her fashionable style. Liao Fan is dressed in black, with a cool Jianghu costume. Whether drinking with others or dancing with Zhao Tao, he is unsmiling and maintains the majesty of Jianghu bosses. The pictures of Liao Fan and Zhao Tao dancing disco perfectly restore the scene of young people dancing disco together in 2000, which makes people feel like going back to that era, showing the enthusiasm and energy constantly stimulated in their young lives with music and dance. In the director’s special feature previously exposed, Jia Zhangke danced a short dance with Zhao Tao on the set, and revealed that Liao Fan and Zhao Tao choreographed their back-to-back dance moves.

In fact, it is not uncommon for people to dance in discos or in groups in Jia Zhangke’s films. In Ren Xiaoyao, young Bin Bin and Qiaoqiao consume their confused youth in discos. In "mountains may depart", the young people in the town, Zhang Jinsheng, Shen Tao and Liang Zi, fell in love and felt free while dancing disco. In Children of the Jianghu, Brother Bin and Sister Qiao, as Jianghu people, danced freely in the disco, which proved that their scenery was infinite at this time. These iconic scenes in Jia Zhangke’s films are not only the plot of the story, but also the vivid memories of youth for Jia Dao.

No one thought that Jia Zhangke, who was gentle and elegant in the eyes of everyone and won numerous awards, was once a "little prince in disco". As early as the film "mountains may depart" was released, Jia Dao once showed his dancing talent slightly. Although the dance steps were a little unfamiliar, it was enough to surprise everyone. In this regard, Jia Zhangke said: "When I was studying, there were many discos next to the school, and I went almost every Saturday. From eight or nine o’clock in the evening, I jumped to two o’clock the next day, and even changed three discos a night. At that time, there seemed to be endless strength in my body." It turns out that this internationally renowned director was once a hot-blooded young man who liked disco dancing!

The film "Jianghu Children" will be released nationwide on September 21st in the Mid-Autumn Festival.

　　Investment of R&D funds from 1953 to 2017

　　Sharp tools make good work. Investment in science and technology is the necessary condition and basic guarantee for scientific and technological progress. Since the founding of New China 70 years ago, China has gradually established a national science and technology investment system that adapts to the characteristics of the socialist market economy system.

　　"The continuous improvement of the national science and technology investment system and the sustained and rapid growth of research and development (R&D) funds have stimulated the vitality of scientific and technological innovation in the whole society and strongly supported the country’s scientific and technological progress and rapid and stable economic and social development." Zhu Yingchun, deputy director of the Institute of Science and Technology Statistics and Analysis of the China Academy of Science and Technology Development Strategy, said in an interview with the Science and Technology Daily reporter.

　　A historic breakthrough was achieved in the scale and intensity of R&D funds.

　　The R&D expenditure of the whole society is an important component of the national (regional) investment in science and technology, an important indicator to measure the national (regional) investment in science and technology, and an important indicator to observe and analyze the national (regional) scientific and technological development strength and competitiveness.

　　Since the founding of New China, especially since the reform and opening up, with the promulgation and implementation of various national economic policies and science and technology policies and the enhancement of the country’s comprehensive national strength, the investment in science and technology in the whole society has increased rapidly, and the scale and intensity of R&D funds have achieved a historic breakthrough.

　　Data from the National Bureau of Statistics show that in 2018, China’s R&D expenditure reached 1,967.79 billion yuan, 123 times that of 1991, from 1991— In 2018, the average annual growth rate was 19.5%, far exceeding the average annual growth rate of GDP at current prices in the same period.

　　At the same time, the investment intensity of R&D funds has hit record highs, reaching 2% for the first time in 2013 and 2.19% in 2018, exceeding the average level of the 15 EU countries. According to the exchange rate, China has become the second largest R&D investment country in the world after the United States, providing a strong financial guarantee for the development of science and technology.

　　China’s national financial expenditure on science and technology increased from 60 million yuan in 1953 to 951.82 billion yuan in 2018. 2005— In 2010, the national fiscal expenditure on science and technology grew fastest, with an average annual growth rate of more than 20%. In 2011, the growth rate began to decline, and in 2018, it increased by 13.5% over the previous year, setting a record high since 2013.

　　"The national financial expenditure on science and technology has played a key role in driving the whole society’s R&D investment and leading the national strategic orientation, providing a strong guarantee for scientific and technological innovation." Zhu Yingchun pointed out.

　　In Zhu Yingchun’s view, the investment in science and technology has increased rapidly, and the scale and intensity of R&D funds have achieved a historic breakthrough, which is in line with the Outline of the National Medium-and Long-term Science and Technology Development Plan (2006— The promulgation and implementation of "2020)", especially since the 18th National Congress of the Communist Party of China, various departments and localities have taken active measures, and the whole society has formed a consensus on attaching importance to and supporting innovation.

　　From different regions, the performance of scientific and technological investment in some places is eye-catching. In 2017, the fiscal expenditure on science and technology in seven regions including Guangdong, Jiangsu and Shanghai exceeded 20 billion yuan. The local fiscal expenditure on science and technology in 11 provinces (cities) accounted for more than 2% of the local fiscal expenditure, and Guangdong, Shanghai and Beijing all exceeded 5%.

　　It is worth mentioning that in 2018, the number of regions with R&D investment intensity greater than 2% increased to 11, among which the R&D investment intensity in Beijing reached a record high of 6.17%.

　　Enterprises become the main force supporting the growth of R&D investment.

　　Since the reform and opening up, China has actively guided other social capitals to increase their support for innovation through direct and indirect financial investment. Enterprise funds have gradually become an important source of funds for the whole society to invest in R&D funds.

　　"In recent years, the source structure of R&D funds has been further optimized, and the dominant position of enterprise innovation has been further highlighted. The proportion of corporate funds in R&D funds increased from 60.1% in 2003 to 76.5% in 2017. " Zhu Yingchun believes that this is mainly due to the improvement and implementation of the R&D expenses plus deduction policy, the tax relief policy for high-tech enterprises and the accelerated depreciation policy for fixed assets, which greatly mobilized the enthusiasm of enterprises for R&D activities. As the main body of technological innovation, enterprises have become the main force supporting the growth of R&D investment in China in recent years.

　　Enterprises are not only the main body of investment in R&D funds, but also the main body of implementation. From the perspective of expenditure structure, the proportion of R&D expenditure of Chinese enterprises in the total social R&D expenditure has increased from about 60.0% in 2000 to 77.4% in 2018.

　　According to statistics, in 2017, the number of enterprises enjoying R&D expenses plus tax reduction and exemption for industries above designated size and tax reduction and exemption for high-tech enterprises reached 24,400 and 24,200 respectively, 3.3 times and 3.5 times that of 2009 respectively, and the amount of tax reduction and exemption reached 57 billion yuan and 106.2 billion yuan respectively, which played a positive role in encouraging and guiding enterprises to carry out R&D activities.

　　In 2018, the basic research funds broke through the 100 billion yuan mark for the first time.

　　Data from the Statistical Bulletin of National Science and Technology Investment in 2018 (hereinafter referred to as the Bulletin) show that in 2018, China invested a total of 1,967.79 billion yuan in R&D, an increase of 207.18 billion yuan or 11.8% over the previous year. Among them, the basic research funds exceeded 100 billion yuan for the first time, reaching 109.04 billion yuan, keeping pace with the investment in research and development.

　　Li Yin, a statistician of the Department of Social Sciences and Literature of the National Bureau of Statistics, explained that the funds for basic research exceeded 100 billion yuan, and all three subjects achieved rapid growth. The funds for basic research in institutions of higher learning, government-owned research institutions and enterprises were 58.99 billion yuan, 42.31 billion yuan and 3.35 billion yuan respectively, up by 11.1%, 10.1% and 15.7% respectively over the previous year. Among them, colleges and universities contribute 51.1% to the growth of basic research funds in the whole society, and they are the main bodies to carry out basic research.

　　According to Lv Wei, a researcher in the Innovation and Development Research Department of the State Council Development Research Center, the investment in basic research in China has been increasing continuously in recent years, which is not only related to the state’s attention, but also an inevitable requirement for the development of technological innovation capability to the stage of "three runs coexist". The report of the 19th National Congress of the Communist Party of China proposed that we should aim at the forefront of world science and technology, strengthen basic research, and achieve a major breakthrough in forward-looking basic research and leading original achievements.

　　Over the past 70 years, China has made remarkable progress in science and technology investment. "However, it should still be noted that compared with the goal of deepening the supply-side structural reform and building a world science and technology power, the investment intensity of R&D funds in China needs to be rapidly improved." Zhu Yingchun pointed out.

　　Judging from the cumulative investment, there is still a big gap between the total investment of R&D funds in China and the United States and Japan since 1991. Science and technology investment has a strong cyclical accumulation effect, and the appearance of scientific and technological innovation effect depends on long-term investment and continuous accumulation. When the innovation ability changes from "tracking, paralleling and leading" to "paralleling" and "leading", it still needs the support of a lot of scientific and technological investment to achieve key core technological breakthroughs.

　　At the same time, problems such as unbalanced investment structure of R&D funds have yet to be solved. For example, the single source of funds for basic research. The proportion of basic research funds in China has been around 5% for a long time, which is lower than 15% in developed countries & mdash; The general level of 20%; Basic research is highly dependent on the central financial input, and local and enterprises have insufficient investment in basic research.

　　In this regard, Zhu Yingchun suggested that in the future, we should speed up the construction of a diversified investment system, strengthen the comprehensive design of fiscal, taxation, financial and other policies, form an organic policy system, and further guide venture capital, charitable donations, and universities’ own funds to invest in R&D activities.
