　　The 21st Guangzhou International Automobile Exhibition (hereinafter referred to as "Guangzhou Auto Show") is in full swing at the Pazhou Complex of the China Import and Export Fair. On November 18, the first audience open day coincided with a Saturday, and the venue was bustling with people.

　　How to visit the auto show? How to choose your favorite vehicle? What are the highlights of the RV exhibition area? What new products and services are launched by smart cars? With these questions in mind, the reporter visited the Guangzhou Auto Show and listened to the voices of the citizens at the scene.

　　Buying a new energy vehicle or a fuel car? Citizens have different opinions

　　This year’s Guangzhou Auto Show has attracted mainstream auto brands and new energy vehicle companies from around the world. The exhibition area covers an area of 220,000 square meters, with a total of 1,132 vehicles on display, of which 469 are new energy vehicles, accounting for 40%. Various brands, rich models, preferential promotions, and diverse price ranges… Guangzhou Auto Show has attracted many citizens to come and buy their favorite models with a series of advantages.

　　In front of the Huawei Hongmeng Zhixing booth, Ms. He was listening carefully to the lecturer’s introduction of relevant technologies and products. She told reporters that she came from Shenzhen on a special trip, hoping to choose the right car here.

　　When it comes to buying traditional fuel vehicles or new energy vehicles, Ms. He said that she prefers to choose new energy vehicles out of her own considerations. "Because I am not very good at parking, I really want to know more about the function of automatic parking. In addition, intelligent driving, automatic obstacle avoidance, artificial intelligence technology, etc., are all my concerns."

　　In the field of new energy vehicles, she is more inclined to hybrid gasoline and electricity. "My budget is within 300,000, and my daily travel is mainly in the upper class and suburbs. When I am on vacation, I may drive back to my hometown. If I can charge and refuel, I will be more at ease." In addition, the car brand is also an important factor affecting Ms. He’s car purchase. "At this stage, when buying a car, I will still choose a well-known car company, and I feel that the quality and safety are more guaranteed."

　　Regarding whether they prefer to buy new energy vehicles or traditional fuel vehicles, the reporter randomly interviewed some citizens at the scene. People who intend to buy new energy vehicles often mention the following points: the price of the car is advantageous, the charging cost is lower, the model is more scientific and technological, the level of intelligence is high, and the relevant policy support; but they also mention mileage anxiety, difficult charging, and insufficient charging infrastructure.

　　Many people who choose traditional fuel vehicles mention that they prefer to use fuel vehicles, which are suitable for long-distance travel, have lower maintenance costs, and better driving experience. However, the disadvantages are that the vehicle price is relatively high, the fuel cost is more expensive, and the product update is slow, making it difficult to meet the needs of intelligent travel.

　　As the car market evolves, so do consumer choices. Mr. Cheng bought a gasoline-electric hybrid in 2017 and a gasoline-powered car three years later. "Each has its own advantages and disadvantages, and it is difficult to generalize," he says. "It is more comfortable to drive a gasoline car on high speed, but it is flatter to drive a hybrid in the city. I will definitely buy a tram in the future, but now I feel that the tram still has a lot of limitations, such as low battery life at high speed, easy to heat up when charging, and not 100% safety."

　　Different groups of people have different needs? Precise positioning of car companies

　　The competition in the car track is intense. How can car companies attract customers with high-quality products and high cost performance? At the exhibition hall, some car companies strive to attract more target customers by reducing prices for a limited time, giving discounts, live streaming, and providing customized services.

　　The needs of different groups of people vary, and automakers need accurate positioning to win customers.

　　In some booths, car companies placed camping tables and chairs, and placed bicycles on the roof to set off the product highlights with specific life scenes. Mr. Ge, who likes cycling and outdoor camping, admitted that "it is really attractive. When I see the car, I think of the outdoor camping scene. My car budget is about 150,000, and after looking around, there are many favorite products."

　　In response to the needs of some family travel, some car companies have positioned themselves as "affordable and easy to drive, comfortable space, and designed for family travel"; some car companies have proposed the concept of giving young people a more ideal "home"…

　　There are also some car companies that are ingenious and choose more niche tracks. For example, GAC Trumpchi launched the E9 Care Edition, which is equipped with electric welfare wheelchairs to facilitate the travel of the elderly, pregnant women, the disabled and other groups.

　　"This kind of innovation is really practical and humanistic," said one of the elderly on the spot. "My parents are old, and it looks good to buy this car to take them around." In this regard, a staff member of GAC Trumpchi said that the car is still in the research and development stage and is expected to be mass-produced next year.

　　Sense of technology, practicality, intelligence, personalization… At the Guangzhou Auto Show, a dazzling array of products with different positioning made the public feast their eyes. "I have been to the Guangzhou Auto Show before, and I can clearly feel the increase in the number of new energy vehicles this year. The exhibition areas of Tesla, Ideal, Xiaopeng, BYD and other new energy vehicle shows are quite cool, and the level of intelligence of the cars is also surprising. Especially the release of some concept cars makes people can’t help but imagine the future direction of automobile development." At the XPeng Motors exhibition hall, Mr. Wang, a veteran car fan, looked at Xiaopengfei’s driving suspended in the air and said.

　　At the scene, many citizens passing by the exhibition area took a group photo with the car, and some people expressed their imagination of "technology changes lives, where to go in the future".

　　RVs are expensive and can’t afford them? 300,000 or 400,000 also have options

　　When asked, how do you feel about coming to the Guangzhou Auto Show to see an RV? Many citizens invariably mentioned that the price of an RV is cheaper than expected, and there are many options for 300,000 to 400,000 yuan.

　　"I used to think that RVs were expensive and only existed in other people’s beautiful travel lives in swipe short videos. But today I came to the RV area of the Guangzhou Auto Show and found out for the first time that I could buy an RV 300,000. My friends and I just went up to experience it, and it was very comfortable. I never had the idea of buying a car before, and this moment was ignited." Ms. Wang, who is in her 30s, said with a smile.

　　Another couple echoed similar sentiments. Mr. Chen, who brought his girlfriend to the show, said: "I didn’t have the opportunity to see so many models before, but today I was really amazed. The price of the RV broke my stereotype." His girlfriend couldn’t help but sigh, "I don’t even want to buy a house with an RV. If the relevant infrastructure can keep up, that would be great."

　　At the scene, Dade RV, Yutong RV, Jiangwei RV, Great Wall RV and other brands displayed a variety of highly competitive products. According to the relevant person in charge of Yutong RV, from more than 80,000 yuan to more than 1 million yuan, they have launched different grades of RVs to meet the differentiated needs of the market. Among them, 400,000 and 500,000 yuan sold more. "Retirees and freelancers buy most of them, they have more free time and like to travel outdoors."

　　A retired couple is sitting in an RV to experience the comfort of the driver’s seat. They also checked the size of the bathroom, the size of the bed board, the length of the water pipe, the size of the water tank, etc. Aunt Huang told reporters that she and her husband have been "playing with RVs" for many years and recently plan to replace them with a new RV. "With an RV, you can travel freely, and you can have a home wherever the car is, and life is full of fun." However, Aunt Huang also recommends that you think carefully before buying a car. Do you really need it? Do you have time to travel? Can you accept problems such as parking difficulties and water and electricity supply troubles? If you just want to experience it, renting a RV is also an option.

In the process of driving Volkswagen’s new Magotan, the replacement frequency of coolant and the antifreeze selected are very important.

According to the official suggestion, G13 purple antifreeze should be replaced every two years or 30,000 kilometers, and the market retail price is about 110 yuan /5L. Antifreeze is not distinguished by brand, but by its color, which is usually red, green and yellow. Magotan usually needs to add about 5 liters, up to 8 liters at most, to keep the cooling system running normally.

For Magotan, the original FAW-Volkswagen antifreeze is enough, and it is usually replaced every 2 years or 60,000 kilometers. Unless there is water leakage, it is generally not necessary to add it frequently. Just add a small amount of water to supplement it when necessary, and the main mission of antifreeze is to protect the safe operation of the engine in low temperature environment and provide efficient heat dissipation.

The standard time for replacing antifreeze is about every two years or 60 thousand kilometers. There are two ways to judge whether it needs to be replaced: First, through visual inspection, if the antifreeze appears black, it means that it may have begun to deteriorate and needs to be replaced in time. The second is to follow the manufacturer’s suggestions to ensure that its performance always meets the standards.

For Magotan, it is very important to follow the replacement cycle of antifreeze. Expired antifreeze may cause internal corrosion of the engine and even cause serious damage. During use, be sure to avoid mixing it with tap water to ensure the best performance.

Finally, when Magotan replaces antifreeze, according to the instructions of the coolant pot in the engine compartment, it is usually necessary to add about 5 liters and keep it within the maximum and minimum scale range. In this way, your car can be kept in the best cooling state.

Hongbao Resources (01131) announced that on December 14, 2016, the Group completed the acquisition of a biodiesel plant in Arkansas, USA through a subsidiary, at a cost of US$ 2.97 million.

Immediately after the completion of the acquisition, the Group and Solfuels Holdings Pte
Ltd. will beneficially own 51% and 49% of the rights and interests of the biodiesel plant respectively. The biodiesel plant has an annual production capacity of 137,000 metric tons and is expected to be put into operation in April 2017.

The Group is a supplier of integrated energy and shipping solutions, and Solfuels is a leading and experienced biofuel operator, operating a biodiesel plant in the United States. The acquisition marks the first time that the Group has entered the field of renewable energy.

According to the company, with Solfuels’ operational expertise, the group expects to transform the biodiesel plant to adapt to a variety of plateau materials, including yellow oil, animal fat, inedible corn oil and refined vegetable oil, and reduce production costs. The group believes that the production of this biodiesel plant will meet the increasing demand for renewable energy in the US market.

On November 28th, 2023, the first model Zhijie S7 jointly developed by Huawei and Chery was announced to be listed in Shanghai.

It is reported that the new car is available in four versions, with a price of 249,800-349,800 yuan, and the starting price is lowered by 8,200 yuan compared with the pre-sale. According to the official introduction, the current order volume has exceeded 20,000 units.

As the first pure electric car of Huawei HarmonyOS Zhixing, Zhijie S7 is deeply empowered by Huawei in the fields of product definition, ID design and user experience.

At the press conference site, through the one-button calling function, the intellectual S7 with no one above the driver’s seat automatically entered the stage. Yu Chengdong, managing director of Huawei, terminal BG CEO and chairman of BU, a smart car solution, said: "Zhijie S7 will launch a number of Huawei black technologies, which will open a new chapter in smart travel."

The brand-new DriveONE 800V silicon carbide high-voltage power platform and Huawei Turing intelligent chassis carried by Zhijie S7 are the key points recommended by Yu Chengdong. A series of data show that the total power of the four-wheel drive combination of front AC asynchronous motor and rear permanent magnet synchronous motor in Zhijie S7 is 365kW, and the acceleration of 0-100km/h is 3.3s. The high-efficiency power system, combined with lightweight body, ultra-low wind resistance and energy recovery strategy, makes its comprehensive power consumption 12.4 kW·h per 100 kilometers, the comprehensive cruising range of CLTC can reach 855km, and the cruising range of 800V super fast charging can be increased by 215km in 5 minutes.

At the same time, Zhijie S7 took the lead in getting on HarmonyOS 4, adding Super Desktop 2.0 and 3D car control desktop, which brought a more easy-to-use and convenient intelligent cockpit experience. The newly upgraded in-vehicle intelligent assistant Xiaoyi supports features such as no wake-up, custom timbre, and can accurately answer users’ questions about vehicle use, such as what to do after a tire puncture.

It is worth mentioning that Zhijie S7 can also realize the only auxiliary parking function of mechanical parking spaces in the industry and support more than 160 parking scenes. If the original parking space is occupied, Zhijie S7 can roam to find a parking space by itself.

According to Huawei’s plan, the parking and driving Beta program will be opened in Beijing, Shanghai, Guangzhou, Shenzhen, Chongqing, Suzhou, Dongguan and other cities in the first quarter of next year, subject to the actual delivery of the products.

The appearance of Zhijie S7 represents Chery’s formal joining in Huawei’s "Car-making Corps". Of course, Chery, Cyrus, BAIC and JAC have all received the invitation from Huawei’s new joint venture company. At the press conference, Yu Chengdong invited FAW to participate. Huawei’s "circle of friends who build cars" is expected to expand rapidly and become more and more popular.

From the orangutans who like to live alone, to the gibbons with white palms, to the langurs with harem, and the cynomolgus monkeys who marry in groups, the primates’ views on marriage and love and the size of their social circle are very different. What kind of driving force has shaped this difference? This question was answered in the study of Asian langur by the team of Northwest University-

In the early morning of June 2nd, Science magazine published the latest research achievement Adaptations to a cold climate promoted social evolution in Asian colobine primates in the form of a long article, which systematically revealed the mystery of primate social evolution for the first time. The cover picture of this issue of Science shows the representative of Asian langur-Qinling golden monkey, and the picture is provided by the research team of Northwest University.

Restore the evolution history of Asian langur social system

"Primates have a complex and diverse social structure. Their social structure has a strong phylogenetic signal, and it has been deeply influenced by historical environmental upheaval and recorded in their genomes. " Qi Xiaoguang, a professor at the School of Life Sciences of Northwest University and co-first author of the paper, said at the press conference on related research results held by Northwest University on June 2.

"We have been focusing on the study of golden monkeys for more than 20 years, using the method of combining GPS collar, satellite remote sensing technology and social network analysis, and through long-term field tracking and observation, we have always wanted to uncover the mystery of primate society." Li Baoguo, a professor at Northwest University and co-correspondent, introduced.

After years of research, the team found that the golden monkey society has a unique four-layer social structure: family, detachment, group and community. In 2014, Qi Xiaoguang and Li Baoguo jointly developed a paper in the journal Nature-Communication, and put forward the hypothesis of "Asian origin-aggregation" for the first time, which broke the single understanding of the complex social origin of primates by western scholars and opened a new avenue for studying the evolution of animal social systems.

This time, the research team extended their eyes to 8 million years ago, and pieced together the diffusion path of Asian langur ancestors from the historical distribution suggested by biological fossils and the excavation of big data such as ancient sea level, ancient geography and ancient climate.

About 8 million years ago in Miocene, the ancestors of Asian langurs spread from Europe.

One of them spread from the Indian Peninsula to Southeast Asia, and this group divided into three genera, and retained the ancestral "single family group" social system of one male and many females.

The other branch spread to Yunnan, China in the late Miocene, and formed the base group of strange-nosed monkeys. With the cold events in the late Miocene in this area, their family groups were no longer mutually exclusive, and sometimes separated and sometimes aggregated, forming a heavy-class society.

Due to the lack of food, most of the strange-nosed monkeys later spread to the south and evolved into different species such as white-rumped langurs and proboscis monkeys. Today, although they live in warm areas of Viet Nam and kalimantan island, they still retain the structural feature of a class-heavy society.

At the same time, the golden monkey, a close relative who stayed in the north of China, drew closer social relations, cultivated long-term and stable ties between families, and evolved a real stratified society in the repeated glacial and interglacial cold events in the Pleistocene.

"We found that species living in cold environments tend to form larger communities, and two social aggregations occurred in the Late Miocene Cold Period and the Pleistocene Quaternary Ice Age, respectively, which indicates that cold events may have driven community aggregation." Qi Xiaoguang said that on this basis, the team put forward the social evolution history of the Asian langur "three acts". This discovery is also a systematic exposition of the hypothesis of "Asian origin-aggregation" put forward by the team.　

Why did you choose the Asian langur as the research object? Scientists have also given the best answer: Asian langur belongs to the Old World Macaca colobus subfamily, with a total of 55 species in seven genera, including four different social system types: monogamous society, polygamous society, stratified society and quasi-stratified society, which are distributed from tropical rain forest to temperate snow-capped mountains. The team believes that this group is a good model for studying the social evolution mechanism system of primates.

In order to do this research well, the team cooperated with universities, research institutes, zoos and other teams at home and abroad to analyze and investigate 2903 habitats of Asian langur, and analyzed the comprehensive ecological factors of 19 environmental variables extracted from each habitat, thus constructing the most comprehensive Asian ecological data set so far.

Establish a research framework of "behavior-ecology-genome"

In the long history of 8 million years, how did the repeated cold events drive the Asian langur to complete the community gathering? This needs to be confirmed by analyzing the genome data passed down from generation to generation.

In order to answer the questions, the team creatively established a brand-new research paradigm of "behavior-ecology-genome". They overcame many difficulties such as cross-discipline and cross-region, completed high-quality genome sequencing of seven representative species of Asian langur, and obtained the world’s first non-human primate genome at chromosome level, thus constructing accurate phylogenetic relationships.

"We combine the central principles of macroevolution’s biology and micro-molecular biology to explore the genetic mechanism behind the cold events driving community aggregation." Qi Xiaoguang said. Through comparative genomics and phylogenetic analysis, it is shown that the cold events in history have promoted the positive selection of energy metabolism and neurohormonal regulation-related genes in Asian langur, and evolved a more effective brain, neurohormonal regulation network. Among them, the gene changes related to oxytocin and dopamine transmitter system in the strange-nosed monkey group are particularly striking: the society of its group presents a two-step step polymerization model, from "polygamy" of its ancestors to the formation of separation.

The team found that in mammals, oxytocin and dopamine can strengthen the bond between mother and child. The cold effect triggered their adaptive changes, strengthened the bond between mother and baby, and prolonged the parental rearing of the strange-nosed monkeys in cold areas. At the same time, the friendly behavior between individuals has also been promoted, which has further promoted the gathering of single family groups to a heavy society. This result has also been verified by cell function experiments and behavioral experiments.

"For example, our Qinling golden monkeys, where the climate is cold and food is scarce, will have more behaviors of holding groups to keep warm and grooming each other. Such a neuromodulation mechanism also indirectly increases the individual’s friendly behavior and tolerance, thus promoting the gathering of family groups to a heavy society. " Qi Xiaoguang said.

This study integrates animal behavior, ecology, geology, comparative genomics and other multidisciplinary means, and completely reveals the evolution process, motivation and genetic basis of the complex social system of Asian langur. Its greater significance lies in the establishment of a new research paradigm of "behavior-ecology-genome", which provides a new way to understand the origin and evolution mechanism of primate social behavior, including human beings, and also opens up a new direction for the development of animal behavior.

As the reviewer of Science magazine commented: "The author has traced back the social evolution history of Asian langur completely through multidisciplinary methods, and comprehensively analyzed its ecological causes and genetic basis, which is unprecedented in the study of primates and vertebrates, and has opened up a new avenue for the field of social evolution."　

Stick to the original heart: "If you like it, you want to protect it."

It is Qi Xiaoguang’s greatest wish for many years to make such a beautiful Qinling golden monkey on the cover of Science for the whole world to see. In 1999, he joined the golden monkey research team of Northwest University, studied under Professor Li Baoguo, and became one of the pioneers in the field research of Qinling Golden Monkey.

"The first time I saw the golden monkey was during the winter vacation of my freshman year." After walking alone for 12 hours, Qi Xiaoguang finally saw them in the depths of the Qinling Mountains: "Wow, they jumped over my head-light yellow hair, light blue skin, pure eyes … so beautiful!" "If you like it, you want to protect it" has become his initial intention to study the golden monkey for more than 20 years.

In his early years, Qi Xiaoguang spent six or seven months every year in the Qinling Golden Monkey Base, crossing the mountains and sleeping around the clock, carefully observing every subtle movement of the Golden Monkey, and spared no effort to collect data and analyze the research results. It is also because they are stationed in the field base all the year round that they explore a set of methods suitable for the study of mountain primate behavior, which lays a key foundation for the follow-up research.

"In the past, the research on the evolution mechanism of primate social systems has always stayed at a purely macro level, lacking in-depth exploration of molecular mechanisms. It is precisely because of the lack of suitable research templates and genome-wide data that there has been no major breakthrough in its specific evolutionary mechanism, especially its genetic basis. " After consulting a number of experts in the animal field, Qi Xiaoguang and team experts began a lonely attempt. Trying to try and make mistakes again and again, overthrowing and reorganizing again and again … It was this time that led Wu Jinwei and Zhao Lan to explore together, which made Qi Xiaoguang unforgettable.

Finally, the team finally found a clue to break through the bottleneck in micro-molecular biology. In the face of an extremely huge, complicated and completely unfamiliar new field, the team is quietly making breakthroughs. "The artificial classification of disciplines makes us only see one side, but biological evolution itself will not be inevitable because of these artificial classifications, which also forces us to look at the process and practice of evolution with a comprehensive eye." Zhao Lan said.

On the campus of Northwest University, Qi Xiaoguang often communicates with the teachers and students of the team of Shu Degan academicians who studied CAMBRIAN fossils 500 million years ago. Although their research period spans hundreds of millions of years, it involves many dimensions, such as behavior, ecology, geology, fossils and heredity. As long as there is an intersection, he will be interested.

"In the future, we will continue to deepen the research on the evolution mechanism of primate social systems represented by Asian langurs, and then explore the origin and changes of early human society." Qi Xiaoguang is full of expectations.

　　2537, this is the number of giant pandas, and do you know how many finless porpoises there are? 1249, less than half the number of giant pandas. In the past, due to the influence of human activities, the Yangtze River appeared problems such as water pollution, shrinking lakes and decreasing fish resources, which led the finless porpoise to fall into an extremely endangered predicament. In 2013, the finless porpoise was listed in the IUCN Red List of Endangered Species. Fortunately, with the orderly promotion of the great protection of the Yangtze River in recent years, "smiling angels" are appearing around us more and more frequently, which also brings us many surprises.

　　This is a precious picture taken by Mr. Ma, a citizen of Zhenjiang, near the Yangtze River in early May this year: a finless porpoise is chasing and catching swordfish. The finless porpoise and saury, two once endangered animals, are rarely "in the same box" in Jiangsu section of the Yangtze River.

　　Jiang Meng, secretary-general of Nanjing finless porpoise aquatic biological protection association, said: "The Yangtze finless porpoise is an indicative species, and there is also an umbrella species in our biology, which means that its large number proves that this ecosystem is healthier, that there are many other fish, and that this water quality is also very good. Therefore, the finless porpoise is an important symbol to measure whether our Yangtze ecosystem is healthy."

　　[The population has fallen into a "trough" at least when it was less than 1012]

　　The Yangtze finless porpoise lives in the main stream of the middle and lower reaches of the Yangtze River and in Poyang Lake and Dongting Lake. The Yangtze River used to be their paradise. Research data show that in 1991, there were about 2,700 finless porpoises in the Yangtze River. As time goes by, this number is decreasing.

　　Jiang Meng said: "The first one is the excessively busy shipping, which occupies space with the finless porpoise and affects its sonar system;" The second is the water pollution of the Yangtze River. For example, the Yangtze finless porpoise ate some garbage or water pollution, which caused many diseases in its body. The third is the destruction of habitat, which has turned many natural coastlines, especially river beaches, into factory docks; The last one is also relatively direct. The reduction of finless porpoise food is due to our overfishing, especially illegal fishing. "

　　[Protect "overweight" more and more of them to thrive in the Yangtze River]

　　If we don’t do it again, we will lose the "smiling angel" forever. Protection, Governance and Restoration … … We realized the seriousness of the problem and tried our best to start action. A number of laws and policies have been promulgated one after another; The concept of "jointly protecting and not developing" has been deeply rooted in the hearts of the people.

　　Jiang Meng said: "The pregnant period of the female finless porpoise is about 11-12 months, and only one child can be born. After birth, the lactation period will reach half a year, and after half a year, it can go fishing independently. In April and May of this year, after our monitoring, at least two young porpoises were born in the waters near Zhongshan Pier and Qianzhou in front of us, which also proved that this population of Nanjing Yangtze finless porpoises is breeding very healthily. "

　　On February 28th this year, the Ministry of Agriculture and Rural Affairs announced the results of the scientific investigation of the Yangtze finless porpoise in 2022. The finless porpoise population was about 1,249. This is the first time that the population of the Yangtze finless porpoise has stopped falling and rebounded since the monitoring record was recorded.

　　【 Remarkable achievements have been made in protecting biodiversity of Mother River 】

　　The finless porpoise is back, and there are more magical elves along the Yangtze River. Wu Jiamin, a photography enthusiast, often shoots along the river with a camera. He said that the environment is good and more and more precious shots can be taken.

　　Wu Jiamin, a photography enthusiast, said: "You can often see creatures along the river, which is obviously more than before, such as spoonbills, snipes and cotton mites. There used to be few people when shooting birds, but now there are many people. Now it is beautiful, there are many birds and the natural environment is good. Nanjing is like a natural zoo. "

　　Jiangsu section of the Yangtze River has a total length of 432.5 kilometers and a coastline of 1,169 kilometers. This basin is home to 1/6 of the ecology along the Yangtze River in Jiangsu. Up to now, the water quality of the main stream in Jiangsu section of the Yangtze River has remained Grade II for five years in a row, and the proportion of the main branch water entering the river is of high quality and Grade III is 98.3%. More and more rare and endangered species have settled down in Jiangsu: Oriental stork and Chinese merganser, the first-class protected animals in China, have frequently wintered in the beaches along the Yangtze River in Zhenjiang in recent years; At the end of March this year, the black-billed gull first appeared on a large scale in Haimen section of the Yangtze River. On May 7th, a critically endangered species, the yellow-breasted sole, appeared in the ecological wetland of Mazhou Island in Jingjiang, Taizhou.

　　Zou Peng, deputy director of the Nature Department of the Jiangsu Provincial Department of Ecology and Environment, said: "According to the results of the background investigation of biodiversity, the number of recorded species in the province reached 6,903, including 4,124 species along the Yangtze River, accounting for nearly 60% of the total in the province. It should be said that biodiversity protection has achieved remarkable results."

　　Cool Guiyang, big coffee gathering, talking about the future of data. From May 26th to 28th, 2021 China International Big Data Industry Expo was held here. The reporter felt at the meeting that big data is profoundly affecting global scientific and technological innovation, industrial restructuring and economic and social development.

　　Multi-expansion of Big Data Fusion, Innovation and Application

　　In the square in front of the Expo exhibition hall, a white bus attracted people to watch. The seemingly ordinary bus is actually a smart nucleic acid detection vehicle, which is equipped with a fully automatic cup-dividing processing system and automatic virus nucleic acid extraction equipment.

　　This is an innovative application of big data integration exhibited by a company engaged in life big data research in Shenzhen. The person in charge of the enterprise said that in the health care industry, such applications have become more and more common.

　　At the Expo, the "Bus-level Data Center Network" project won the "Black Technology Award". The project has carried out innovative research in topology, forwarding mechanism, chip algorithm and other dimensions, and solved the "stuck neck" problem of domestic switching chips. In addition, more than 800 new products, technologies and solutions such as "Baidu AI Cloud", "Easy Whale Full-stack Domestic Bank Core Transaction Solution" and "360 Security Brain" were all unveiled.

　　As the first comprehensive experimental zone of big data, Guizhou has vigorously developed the digital economy, from "preempting the machine" to "grabbing the new machine" with remarkable results. According to Cai Chaolin, vice governor of Guizhou Province, in 2020, Guizhou’s digital economy rose against the trend, with a growth rate of over 15%, ranking first in the country for six consecutive years. The integration index of big data and real economy reached 41.1, an increase of 7.3 over 2017. Big data has achieved a wonderful "triple jump" from "wind and water" to "taking root" and then "gathering into potential" in Guizhou.

　　Experts pointed out that in the process of expanding big data application scenarios and actively promoting all-round deep integration of digital technology and economic and social development, it is necessary to consolidate the computing power and talent base, strengthen the construction of computing power infrastructure, and fill in the shortcomings of key technologies and industries.

　　Perfecting data governance and promoting fair competition

　　Accelerating the development of digitalization and building a digital China is an important task defined in the "14th Five-Year Plan" and the outline of the long-term goal in 2035, and it is also an important breakthrough direction for the innovative development of hundreds of businesses, and data competition is inevitable.

　　Asset management, shared circulation and security governance of data are directly related to the high-quality development of digital economy. At the Expo, Shi Denian, deputy chief engineer of China Information and Communication Research Institute, released the Report on Data Valuing and Data Factor Market Development, and proposed that data value is concentrated in data resource utilization, data capitalization and data capitalization.

　　"With the continuous growth of data volume in China, the demand for data centers is increasing, and it is very important to realize the independent control of various products in data centers." Wu Hequan, an academician of China Academy of Engineering, said.

　　The vigorous development of digital technology makes the voice of big data rule by law stronger, and data security governance and personal information protection have become the focus of attention.

　　Experts believe that by establishing and improving the governance system and related systems, under the premise of ensuring personal privacy and data security, we will explore more accurate data confirmation, more convenient data transactions, more rational data use, promote fair competition and oppose monopoly.

　　Judging from the evaluation results of the rule of law index of big data in 2020 published at the number fair, the information system of rule of law has been basically completed, data legislation has been in full bloom, digital justice has been steadily promoted, digital rights protection has been improved day by day, and the development of rule of law in big data has made great progress.

　　The draft data security law will be reviewed for the third time at the 29th session of the 13th the National People’s Congress Standing Committee (NPCSC) from June 7 to 10. In this regard, Jason. JS, vice president of china law society, said that it is necessary to strengthen the safety management of important data leaving the country and earnestly safeguard the sovereignty of national data.

　　"The current network security situation is very serious." In the keynote speech entitled "Building the Security Line of Industrial Control System with Active Immune Trusted Computing", Shen Changxiang, an academician of China Academy of Engineering, proposed to pay attention to the security of industrial control system. He believes that to build a triple protection framework, we can trust computing security, trusted boundaries and trusted network channels.

　　Enhance the kinetic energy of open development in the digital field

　　In the past seven years, the Expo has witnessed the magnificent development of the global big data industry, and gradually developed into an international event full of cooperation opportunities, leading the development of the industry, and a world-class platform to discuss development plans and share the latest achievements.

　　The Expo not only created opportunities and gathered resources for the development of big data in Guizhou, but also contributed China wisdom and provided China’s solutions for the development of global big data.

　　On May 27th, "Counting the Valley in China" (overseas version, English version) was first published at this year’s number fair, and three development visions were put forward: the number power law leads the future rule of law and reconstructs the new order of digital civilization; Strengthen data security governance and promote the construction of a community of cyberspace destiny; Governance of science and technology opens up a new realm of "China governance" and promotes the modernization of governance system and governance capacity. This indicates that Guiyang is moving towards a new stage of branding and internationalization in building "China Valley".

　　Open cooperation is an inherent requirement for the development of big data industry. Vladimir Norov, Secretary-General of the Shanghai Cooperation Organization, delivered a speech at the opening ceremony of the Expo, saying that the related technologies of big data have reached a high maturity, and their application in all aspects of economic and social development has brought remarkable results. The successful implementation of technologies related to big data and artificial intelligence will open up new growth opportunities for developing countries.

　　Wei Zhang, vice president of the Institute of International Trade and Economic Cooperation of the Ministry of Commerce, said that looking to the future, we should seize the opportunity of digital transformation, strengthen the top-level design of digital trade development, actively participate in the negotiation and formulation of international rules, and enhance the momentum of open development in the digital field.
