Changchun, China, March 11 (Reporter Guo Dongyu) How important is a good seed for food production?

　　"Good seeds, good rain and good moisture can make us look forward to a bumper harvest year." Han Fengxiang of Fenghuangshan Agricultural Machinery Farmers’ Professional Cooperative in Lishu County, Siping City, Jilin Province said.

　　"The contribution rate of excellent varieties to grain production has reached more than 45%, which plays a vital role in national food security." Zhang Zhijun, a researcher at the Corn Research Institute of Jilin Academy of Agricultural Sciences, said.

　　"I have a dream, buried in the soil, convinced that it is different. Light gives it hope, rain nourishes it and grows with the seeds. " Yuan Longping, the father of hybrid rice, said.

　　This year, the No.1 Document of the Central Committee proposed that the seed industry should be revitalized in depth, the pace of industrialization of corn and soybean biological breeding should be accelerated, the pilot scope should be expanded in an orderly manner, and planting management should be standardized.

　　Recently, the reporter walked into Gongzhuling City, the founding unit of the National Modern Seed Industry Park and a national-level rice seed production county, to see how Jilin people on the black land grasped the "core" of grain.

　　In the more than 20,000 mu seed field of Hongxiang Seed Industry Co., Ltd. (hereinafter referred to as "Hongxiang Seed Industry") in Gongzhuling City, the land has been turned over and the organic fertilizer has been piled up at the edge of the field. "This seed production base was transferred last year. We used the method of black land protection to produce seeds. After a year of practice, the seed quality is very good." He Wei, general manager of Hongxiang Seed Industry, said.

　　Walking into the seed cultivation room, a fresh new green brings ying ying spring. "This is our trial variety and we are testing the emergence rate." He Wei said, "The seedlings in this germination box grew the day before yesterday, and each leaf of them contains a lot of information, which is very important for us breeders." Here, enterprises invest about 50 million yuan in maize breeding every year. "We carefully selected the seeds and planted them in the experimental field. Through the growth and yield, we found those plants with less diseases, lodging resistance and high yield."

　　In addition to constantly researching and developing new varieties, how to make seeds more suitable for modern agricultural production methods is a problem that the Corn Research Institute of Jilin Academy of Agricultural Sciences is currently thinking about.

　　"At present, one of the main problems in corn production is that the level of mechanized harvesting of seeds is low. At present, the harvesting method is mechanical harvesting of ears or manual harvesting, which is not conducive to large-scale production." Zhang Zhijun, a researcher at the Corn Research Institute of Jilin Academy of Agricultural Sciences, said.

　　In recent years, the corn research institute of Jilin Academy of Agricultural Sciences has taken the research and development of new varieties suitable for modern production methods as its main research goal. "At present, we have cultivated Jidan 66, Jidan 436, and Jidan 81 and 82, which will be approved soon. It can be said that grain harvesting is a strong support for Jilin agriculture to take the lead in realizing agricultural modernization in the future." Lu Ming, deputy director of the Corn Research Institute of Jilin Academy of Agricultural Sciences, said.

　　Document No.1 of Jilin Provincial Party Committee issued this year made it clear that it is necessary to implement the project of improving corn yield per unit area. Screening and popularizing new maize varieties with density tolerance, high resistance and high yield.

　　"Every seed we develop must first ensure safety and good resistance. No matter what kind of environment, it can grow. The second is high yield, which allows farmers to increase their output after planting. " He Wei said. Hongxiang Seed Industry plans to reach the production capacity of all four design production lines as planned before 2025, meeting the production demand of 100,000 mu. "In the future, we can serve the whole park, let the seed industry in Jilin Province come back and build a spring corn processing base."

　　It is the wish of Jilin breeders to cultivate a good seed and plant a good field, and it is also the road they will always stick to.

In addition to letting three people not have to "share the same bed", this is more determined. Strikingly I have always believed that the power of the Internet will stimulate everyone’s potential, and every idea should have a chance to become a reality. Break the technical barriers of the Internet, so that everyone can10Create a website in minutes.

from10㎡, arrive200Countries

from YC After graduation,Strikingly The rapid development in Silicon Valley is not over. After replying to tens of thousands of user emails, Chen Haisha became a veritable "CEOChat tool ". This almost "stupid" demand survey and user feedback communication is Strikingly A tradition that we are proud of so far.Strikingly Even set up a special one called "Happiness Officer"team, to help users solve problems when using products, but also for the people and stories behind every website. And "without any programming technology and design experience, it can be used in10Create a professional website that automatically matches screens of all sizes, such as computers, tablets and mobile phones, in minutes.200Users in many countries and regions have been recognized.

As the chief product officer said slowly, "In Strikingly The great benefit of work is that you can always take advantage of your position to chat with all users. They like you or hate you. They tell you what is wrong or what you need, and then you will know that you are one step closer to a better website building tool. "

Different from the "one-hammer sale" of ordinary website construction services, right Strikingly And "online" users, it is not just a website that is created or used, but an Internet technology partner that keeps updating iterations every week and grows with the market and user needs.

To win the hearts of users, besides updating technology and developing products, it is important to pay sincere attention. Although the entrepreneurial process is hard, Chen Haisha also said that these will pay off. "Later, I received a birthday cake in a hotel in Turkey, ate and drank in a Japanese user’s home for a week, and received a letter from a Brazilian actor, thanking us for changing his life. In fact, I still have selfishness. These are the great achievements of starting a business. "

China market, "online" officially launched.

This may be the most tongue twister-like opening remarks of this year’s conference, but the experience of "online" is not "around" at all. It is minimalist, direct and WYSIWYG, which is the evaluation of this website building tool by most users and guests present.

"On-line" adhering to Strikingly The technology of building a website platform is based on, and more localized development has been done. In addition to moving the server to China, improving the overall access performance and supporting website filing, the "online" online mall function has been connected to Alipay, and it has also been deeply integrated with WeChat in the process of creating and sharing websites. The "on-line" website building technology enables users’ websites to automatically adapt to all access terminals, which is particularly important now that the mobile Internet traffic exceeds that of computers, especially in China.

When deciding to develop the independent China brand and product "Online", there were also friends in the circle who doubted whether "Silicon Valley Foreigners" would be acclimatized in the China market. Chen Haisha replied, "We are a China company, and we know China better than all the international platform products, and our team also stayed in Shanghai.threeYears ago, if you want to say that you are not acclimatized, in fact, you were worried that there would be more acclimatization in Silicon Valley. "

But perhaps in the China market, the most "dissatisfied" point has been overcome.Strikingly A very concise and clear Chinese name was given.　— It’s online

Good products will spread themselves.

2In June, Online released a beta version and invited a small number of seed users to try it out. The spread among users has made the "online" star users include Ant Financial, Nail,blackboxChina Training Camp,TeambitionGoddess evolution theory, etc. The positive comments from users also made the "online" team members very excited.

"The greater feature of’ online’ is to hide the powerful network technology, so that users can ignore the heavy back-end work and only focus on the website content itself. It may be too early now, but it is very close to the day when’ online’ becomes a’ revolutionary product’. "

Chen Haisha said："What we have solved has always been the most essential problem in the Internet age. Although the internet has made our life so convenient, we still need to find a supplier or programmer to go online. We want all brands or products, groups or individuals to focus on realizing their ideas, and let the matter of building a station go online. "

　　As the Olympic Games in Rio de Janeiro, Brazil are coming, I would like to review the history and see which scientific and technological products that appeared in previous Olympic Games are still in use today.

　　2000Sydney 2008 Olympic Games

　　1.shark skin like swimsuit

　　For the first time in the Olympic Games, Australian star Thorpe won three gold medals in this swimsuit. Many swimmers try to enhance their competitiveness by using a "shark skin" one-piece swimsuit with a V-shaped back. Because according to the manufacturer of this swimsuit — — Speedo claims that it can increase the speed of swimmers by 3%.

　　2.Trait racing suit

　　Marion Jones in the United States and Cathy Freeman in Australia and other sprint stars use special running clothes developed by Nike. This kind of running suit is very sleek and has a hood, which can cover all parts of the sprinter except his face, hands and feet. This can keep the muscles warm and compress, and improve the sprinter’s performance.

　　3.Recycled products sports equipment

　　Steve Moneghetti, an Australian marathon runner, took part in the competition wearing shorts and vest made of recycled soft drink bottles. According to the manufacturer Nike, this material is cooler than other fabrics.

　　Olympic 100-meter champion Donovan Bailey put on special running shoes made by Adidas. It is said that this special running shoe has a hard metal plate, which can keep human toes as stiff as jaguar’s claws when running.

　　2004Athens Olympic Games in 2008

　　2008Beijing Olympic Games in 2008

　　The 2008 Beijing Olympic Games adopted a large number of world-leading new technologies, such as ground lifting stage, multimedia, ground LED system, command system, communication system and other dozens of high and new technologies, involving many fields.

　　1.Digital lamp

　　The Olympic rings rose slowly in the Bird’s Nest and flew into the vast night sky. China’s ancient painting and calligraphy scrolls slowly unfolded, showing the classical artistic conception of ink painting; On the ancient Silk Road, huge wooden boats braved the wind and waves — — These shocking visual effects are outlined by the gorgeous lights of the Bird’s Nest.

　　At the opening ceremony of the Olympic Games, more than 600 competition lights in the Bird’s Nest were all abandoned, and Zhang Yimou chose its own lighting. Science and technology have entered the digital age, and the lighting effect has also transitioned to digital lights. This new lighting effect makes the scale and imagination of the stage effect of the opening ceremony of the 2008 Olympic Games to the extreme. Digital lights are used in the 2008 Beijing Olympic Games: PG lights, that is, high-brightness projection lamp. By using the principle of optical projection and high-brightness light source, the contents on the negative are projected to the ground in full color, which can form a very visual impact picture effect at night. In the performance of the opening ceremony, the large scroll that runs through the center of the venue and the evolution animation from ancient times to modern times are successively displayed on the scroll, all of which are projected to the center of the venue by this PG lamp after pre-production. The simplicity of black-and-white contrast of China ink painting, the splendor of western oil painting and the strong color of Impressionism are all presented by this high-tech technology.

　　2.LED

　　LED (Light Emitting Diode) is a semiconductor solid light emitting device, which uses a solid semiconductor chip as a light emitting material. When direct voltage is added at both ends, carriers in the semiconductor recombine to cause photon emission and generate light. LED can directly emit red, yellow, blue, green, cyan, orange, purple and white light.

　　In the 2008 Olympic Games, LED was used to the maximum extent. The opening scroll is opened on a huge LED screen. The screen is 147 meters long and 22 meters wide. It is a huge platform with the highest scientific and technological content, with 44,000 LEDs on it. The light and shadow effects made by LED are closely combined with performances, which conjure up various patterns and introduce the audience into a fantastic world. After repeated tests, LED can completely stand the tests of stepping on by actors and flooding. Although the whole opening ceremony took a long time, the key technologies such as battery solved the energy problem of LED.

　　3.Aluminum alloy material

　　At the opening ceremony of the 2008 Olympic Games, a big hole was opened in the center of the stage, and a "earth" with a height of 6 stories and a diameter of about 20 meters slowly rose from it. Where is such a big "earth" hiding? It turns out that this "earth" is compressed underground first, that is to say, the spherical structure must be flexible. When placed on the ground, it is oval, and it will become spherical after being pulled up by the steel wire above.

　　After the ball is lifted by the lifting platform, the actor needs to perform on the vertical surface of the ball, so it needs strong stability after lifting to ensure the safety and effect of the performance. This all depends on high-tech aluminum alloy photosensitive materials, which makes the "earth" flexible.

　　4.multi-media

　　At the opening ceremony of the 2008 Olympic Games, "birds" and "whales" flew and swam freely over the huge scrolls. How did these come about? It turns out that slide projection technology was used in the opening ceremony before, but this time, all kinds of multimedia equipment were used. It can use computers to digitize media information such as words, graphics, images, animations, sounds and videos, and then integrate them into a certain interactive interface, so as to create a bowl-shaped screen of thousands of square meters at the top of the Bird’s Nest, showing a clear picture of the whale swimming freely and expressing the harmony between man and nature.

　　5.Digital ignition

　　Twenty-nine huge colorful footprints made up of fireworks opened the curtain of the 29th Beijing Olympic Games, symbolizing that the modern Olympic Games is coming towards Beijing step by step and entering the Bird’s Nest. The lighting of these 29 big footprints is controlled by computer system and digital lighting is adopted. This technology can ignite all fireworks in a short time, ensuring that fireworks can cross 3.5 kilometers in just a few seconds. In addition, there are 22 launching points in the dragon-shaped water system next to the Bird’s Nest. After digital control by computer, all fireworks bombs can shoot into the sky one after another, making the fireworks look like a flying dragon. Although traditional fireworks are still used, after digital ignition, fireworks show different visual effects from the past.

　　2012London 2008 Olympic Games

　　1.Photographic robot

　　Getty Images, the official photo agency of London Olympic Games, installed photographic robots in some Olympic venues, which can realize remote control and 360-degree rotation. According to the NBC report, "photographic equipment can be hidden in flashlights, rafters and scaffolding, and placed in and around the Olympic Games, which can play the most important role in places where photographers can’t reach because of distance and safety reasons."

　　2.A more attractive voice

　　It is reported in the Atlantic Monthly that most of the voices heard on TV during watching the Olympic Games are not true. Some sounds were not recorded at the game site, at least in this sense, it is not true. Some audio is recorded in advance under optimized conditions and then used for TV broadcast. The website of Atlantic Monthly also cited an example of the Olympic archery competition. An Olympic audio engineer said that the sound was based on the sound he heard in the movie Robin Hood. He used a special microphone to collect the sound on the ground between the archer and the arrow rake. It is said that this method produces a sound that no one can actually experience at the scene.

　　3.Double runway

　　The runway of the main stadium of London Olympic Games has adopted a brand-new surface, which means that track and field athletes do not need to wear spikes to participate in the competition. According to the BBC, "Other runways are designed with rubber particles on the top floor, which combines the traction and shock absorption. Different from the past, the runway designed by Mondo separates these functions into two layers. The bottom layer is padded, which can cushion and shock absorption, and the top layer is durable, which can maximize the skid resistance, adhesion friction and durability. " This design makes it unnecessary for athletes to wear spikes on the track.

　　4.artificial limb

　　South African athlete Oscar Pistorius, who has nicknames such as "Oscar Pistorius" and "the fastest legless man in the world", became the first athlete to use artificial limbs to participate in the Paralympic Games. After a controversy over whether artificial limbs should be allowed to participate in the Olympic Games, Pistorius used special carbon fiber artificial limbs to participate in the 400-meter and 4×400-meter relay races.

　　5. Athletes who put data first

　　London Olympic Games is a "digital Olympics". Many athletes use sleep tracking devices and motion capture systems to understand their physical condition more accurately. According to the Financial Times, some companies dealing in biometric instruments also deal with athletes to participate in data collection to improve the performance of gadgets.

　　6.Virtual bicycle

　　Although it is thousands of miles away from London, Australian cyclists have been training in London cycling track by using virtual reality technology. In a video of the Australian Broadcasting Corporation explaining the technology, it can be seen that cyclists are looking at a screen that looks like a video game, which is actually an environment that is completely simulated according to the London Olympic Road Cycling Stadium. Each training bicycle is fixed in the Australia Institute of Sport, but it is equipped with a screen, a GPS and some ranging tools. This system can also collect the training data of athletes, and the coach can clearly know their time-consuming, speed, energy and riding distance.

　　7.start detection system

　　Omega, the official timer of the Olympic Games, brought a new starting equipment to swimming and track and field events in London Olympic Games. The track starter is fully electronic for the first time. It is said that the technology in the 1970s required athletes to push the starting device 5 mm to start. Now, swimmers start to light up directly to show who is in the first place, who is in the second place and who is in the third place.

　　8.Kick sensor

　　Originally, the Olympic Games may cancel the Taekwondo competition, but technically recording the strength and accuracy of kicking may save the event. Zhao Zhengyuan, president of the World Taekwondo Federation, said in an interview: "I think Taekwondo will really benefit from technology, because it can ensure that medals will be awarded to the best athletes and will not be awarded to others because of misjudgment by the referee. This is an excellent opportunity for us to stay in the Olympic Games. There are few competitions with this technology, which will help to eliminate human errors in taekwondo competitions. "

　　9.Digital housekeeper

　　Being selected for the Olympic Games is not only a proof of strength for an athlete, but also a supreme honor. Can the organizers of the Olympic Games use the power of science and technology to help athletes concentrate on the competition and eliminate their worries in life? Atos, the digital partner of the London Olympic Games, did just that. Atos Company established an identity information system for nearly 15,000 athletes who participated in the Olympic Games and Paralympic Games. The athletes who were included in the system were equivalent to obtaining a certification label, which made it easier to obtain visas and a series of preferential policies. Atos Company has also compiled a supporting application, so that athletes can log in to their identity accounts through their mobile phones, tablets or computers on weekdays. The account will contain a lot of information including the competition schedule, training plan and competition results, which is equivalent to providing a "digital housekeeper" for each participant.

　　10.Reduce the burden on runners

　　As a space power, the United States has also applied its own space technology to the preparations for the Olympic Games. Shannon Rowbury, a well-known American long-distance runner, unfortunately suffered from an injury and her femur was damaged. However, with the help of space science and technology, she only rested for six weeks after diagnosis and resumed training. Robery uses a set of AlterG anti-gravity running assistant device, which allows the trainer to train with at least 20% of his own weight, and the physical burden of the athlete will be greatly reduced. The principle of this treadmill is to pump air into the air bag around the runner’s waist. When the air pressure in the air bag rises, the runner will be lifted and the weight load will be reduced. Athletes can reduce their weight by up to 80% simply by pressing the up/down buttons in the panel.

　　11.Team overall data analysis

　　For cyclists, the wind tunnel laboratory is their loyal scientific and technological partner. The data analysis in the wind tunnel laboratory can help athletes optimize training programs, adjust training methods, and improve their performance by using aerodynamic scientific and technological achievements. But for a long time, the analysis of wind tunnel laboratory can only serve an athlete on a personal basis. Researchers at Monash University in Australia have improved an experimental device used to test airplanes and cars, enabling it to collect data of athletes for analysis. More crucially, this machine has crossed the barrier of analyzing individuals before, and can analyze the data of the whole bicycle fleet at the same time. In this way, the coach can make a training plan for the whole team according to the analysis results and find ways to improve the team’s performance.

　　12.Red BullXplan

　　Although an athlete participates in the Olympic Games alone, he represents more than just him. Behind the athletes, there is a team of coaches who support his motherland and train for him. Lolo Jones, an American hurdler, participated in the Red Bull Project X. She once said in a video: "I’m not fighting alone". The video shows the whole team behind Jones: a coach, a director, a manager, a sports scientist, a coaching consultant and a physiology consultant. Such a rich and powerful work team is naturally not busy in vain, they use the most cutting-edge technology.

　　The Red Bull X project uses a 3D digital analysis system, which can do many things that humans can’t. Plan X is divided into three parts — — Vicon 3D tracking system, optical measurement system Optojump Next and data acquisition tool Phantom Flex Camera. The three technologies complement each other, which can not only give a macro evaluation of athletes’ performance, but also disassemble every minute of training competition into countless tiny fragments for analysis.

　　Jones’s team made 39 reflection marks on her body. With these marks, 40 Vicon T40S motion capture cameras capable of shooting 2000 frames per second will track all her movements. Optojump Next, an optical measurement system, will decompose every jump of Jones into contact time, flight time, height, hurdle rhythm, specific energy, specific power, total energy and total power. Finally, Phantom Flex Camera, a top camera capable of shooting 10,750 frames per second, will record Jones’ every minute with images.

　　"If technology can help an athlete perform better, then this system can benefit everyone." Jones’s average hurdle time is 12.5 seconds, which she believes is largely due to the help of the team and technology behind her.

　　13.Real time feedback device

　　Good results in the competition will be cheered by the audience and graded by the referee. However, in training, how do athletes know their performance? Jonathan Green, composer, sound engineer and Gregory Sporton, dancer of the Visualization Research Unit at the Birmingham Institute of Art and Design in Birmingham, England, developed a feedback system called Motivepro. The original intention of this system is to provide real-time action feedback for dancers. Dancers are required to wear a series of sensors, and their movement information will be collected by Motivepro. Once the wearer’s physical activity exceeds the preset range, the vibrator in the device will vibrate to remind him.

　　Mimi Cesar, a rhythmic gymnast, found that this system can also be applied to rhythmic gymnastics similar to dance. For rhythmic gymnastics, the synchronization of the team is particularly critical. Motivepro system can give a reminder when an athlete’s movements are out of step, and can also collect sports information for the coach to analyze. With this system to help train, will the cooperation of the whole team be more tacit?

　　14.Brand-new pool take-off platform

　　The 2012 London Olympic Games used a brand-new upgraded swimming pool jumping platform in swimming competition. The platform was designed and manufactured by Omega. Compared with the previous take-off platform, the progress is that it has an adjustable inclined pedal certified by patent, which makes the athlete’s hind legs bend into a 90-degree angle when taking off in a squatting manner, which is considered to be the most suitable take-off posture. The new take-off platform is also equipped with a brand-new sensing system. This sensing system can ensure that athletes can hear the whistle at the beginning of the game at the same time, which can effectively avoid unnecessary mistakes of athletes. At the same time, the newly upgraded swimming pool take-off platform in Shanghai is equipped with a signal light system called "Swimming Ranking Indicator". At the end of the competition, the swimming lanes that won the first, second and third place will be marked on the take-off platform by different light spots, so that the audience can see at a glance.

　　15.Advanced drug testing equipment

　　GlaxoSmithKline is at King’ s College next to the Olympic Park. S College) has set up The Science Centre to serve the Olympic drug testing. During the Olympic Games, the center worked 24 hours a day, monitoring more than 6,000 urine samples and blood samples every day. After each competition, all the medal winners and the remaining half of the randomly selected contestants enter the center for illegal drug testing. The tested samples are divided into two parts, A and B, and A is stored for eight years for future more advanced scientific and technological testing; B was sent to the drug testing center. The drug testing center can check 70 illegal drug ingredients in one test, and each sample will be tested here for a total of 240 illegal drug ingredients. It can be seen that the fair conduct of the Olympic Games has a strong technical guarantee.

　　16.Electronic medical records

　　General Electric (GE) Medical Company provided an electronic medical record solution for the 2012 London Olympic Games, which made it possible for doctors and athletes to make medical records accessible through the Internet. The electronic medical records covering more than 700 participants were made in 90 days after the countdown to the London Olympic Games. At the same time, GE Medical Company also installed medical diagnostic equipment in the Olympic Park as a supporting facility for the whole set of electronic medical records.

　　17.Top medical logistics

　　During the Olympic Games, more than 16,000 Olympic athletes and more than 6,000 Paralympic athletes living in the Olympic Village will be fortunate to receive top-level medical logistics support. The latest version of super-large magnetic resonance imaging instrument, ultra-high-definition CT instrument, wireless digital X-ray detection system, upgraded ultrasonic detector and ECG detection equipment specially designed for the Olympic Games provided by GE Medical Company have all opened the eyes of medical volunteers for the Olympic Games. These equipments will not be removed after the Olympic Games, and they will continue to serve in this land that bears cheers and sweat.

　　2014Winter Olympics in Sochi in

　　Snow making: snow cannon

　　Snow making machine is a brand-new snow making system, which forms ice on an evaporator at -15℃ and sends it to ski slopes through cooled air. Due to the climate, Beijing and Zhangjiakou host the Winter Olympics, and a large number of snow making equipment will be used. Funa machine is not affected by climate, so long as it can keep a certain amount of water, it can make snow.

　　At the Sochi Olympic Games, the venue was really unfortunate — — Sochi is one of the warmest regions in Russia. In order to ensure that there is enough powdery snow to support the competition, Russian organizers use snow cannons to shoot a large number of artificial snowflakes. According to the news released by The New York Times, about 230 million gallons of water were used to make snow in this competition, and the snowfall covered an area of about 1,000 football fields.

CCTV News:Regarding the economic data released by China in the first quarter, multinational experts said that the economic data of China in the first quarter was better than market expectations, which indicated that China’s economy was making great strides, and China’s economic prosperity and development not only benefited China, but also benefited the whole world.

Surab Gupta, a senior researcher at the Center for Sino-American Studies in the United States, said that China’s GDP in the first quarter increased by 4.5% year-on-year and 2.2% quarter-on-quarter, which is a good sign that China’s economy is making great strides, and China will have a bumper harvest year in 2023.

Surab Gupta, Senior Researcher, Center for Sino-American Studies, USA:What we are seeing now is that China is striding forward, and the economic development speed is faster than the market expectation. Frankly speaking, I think China’s economy will soon reach the speed of take-off. In terms of economic growth, 2023 will usher in a bumper year.

Vitol Gaspar, director of the Financial Affairs Department of the International Monetary Fund, said that China’s economy has maintained growth not only because it can adapt to the needs of development and carry out transformation, but also because it insists on the effective combination of expanding consumption and deepening supply-side structural reform.

Vitol Gaspar, Director of the Financial Affairs Department of the International Monetary Fund:I think that China has a very strong growth record in the past 45 years, and China has proved that rapid growth and development are extremely important, and it has indeed lifted hundreds of millions of people out of poverty. With the continuous expansion of China’s scale in the world economy, it is very important for China to give priority to the growth of domestic resources, which shows Chinese’s intelligence.

David Falstein, president of the George Bush Foundation for US-China Relations, said that China’s economy started well in 2023, which benefited from the reform and opening-up policy, and China’s economic achievements were also conducive to global economic development.

David Falstein, President of George Bush Foundation for US-China Relations:Under the reform and opening-up policy, China has obviously achieved success. From the economic point of view, China has been on the right path for a long time, and China has been creating prosperity, improving living environment and improving material conditions. I think it is in the interest of China and the global economy to continue on this path.

　　According to Voice of China: Recently, Voice of China continued to report a secondary vocational school in Henan — — There are some problems in Henan Polytechnic School, such as forging student lists to obtain state education funds and renting state assets for illegal profits. In this regard, the staff of the Henan Provincial Department of Finance said that the school had previously had some expenses that were not uniformly registered and accounted for in the accounting books set up according to law, and that the school had been punished for privately storing public funds.

　　The Henan Provincial Department of Education said that it had been investigating and verifying the forgery of the student status list to obtain education funds, but it was unable to provide reporters with the list of students used by the school to apply for per capita funding. In fact, in recent years, the problems of enrollment, charging and management of secondary vocational education are not uncommon. Then, how to supervise the chaos in secondary vocational education?

　　Forged the student list, rented the teaching building, and the funds fell into the private "small treasury"

　　Informed sources told reporters that in recent years, there have been many students who dropped out of school early without completing their studies, and the school information still shows that they are studying at school. Based on this, the school has obtained the education funds allocated by the province.

　　Insider: "But what does it mean that students are still registered as students, and they are still registered as students?" That is, as soon as he registered, he handed it to the Education Department. This is not registered, and then this list was handed over to the Finance Department, and this student was dialed. "

　　The school staff provided the reporter with a list of 118 students who dropped out of two colleges early, and the Voice of China reporter verified them one by one. All the students in this list dropped out of school for different reasons in less than one year. However, most of the students’ information shows that they are still in Henan Polytechnic School.

　　Reporter: "Have you been studying in this Henan Polytechnic School for 16 years?"

　　Lost students: "Yes."

　　Reporter: "So you haven’t been there for a while?"

　　Lost students: "About a year."

　　According to the funding basis of the per-student funding of vocational schools in Henan Province, full-time vocational schools allocate funds strictly according to the number of students’ status, and the subsidies for different majors such as arts and sciences range from 5,000 yuan to 7,000 yuan per person per year. For those students who dropped out of school early, but their school status is still in school, the school theoretically received per capita funding.

　　In addition, many school staff reported that the school’s income from renting state assets including the comprehensive teaching building was not recorded, and the principal set up a "small treasury" privately.

　　The number of forgers and the allocation are still being verified, and the private small treasury is fined 10,000 yuan.

　　In response to this matter, the Voice of China reporter contacted the Henan Provincial Department of Education many times. The relevant staff of the Department of Education responded that the relevant situation has been investigated and verified, but the Department of Education does not have a list of students provided by the school to apply for per capita funding, and the funding is the responsibility of the financial department. The reporter then contacted the Henan Provincial Department of Finance, and the staff of the Department of Finance said that the financial department allocated funds according to the data provided by the education department.

　　Staff of the Finance Department: "We still record the number of students provided by the education department into our budget system, and determine its quota according to the number of students."

　　In addition, the staff of the Henan Provincial Department of Finance said that an administrative penalty of 10,000 yuan had been imposed in accordance with relevant regulations.

　　Expert: We should strengthen supervision and improve the funding system and methods.

　　In fact, in recent years, there have been incidents of false enrollment, arbitrary charges, and taking funds from secondary vocational education. In this regard, Wang Jianzhuang, executive dean and chief researcher of Henan Institute of Private Education, said that in addition to the main responsibility of the school, the living environment of secondary vocational schools, the utilitarian consciousness of individual schools and the official standard structure of vocational schools are all factors.

　　Wang Jianzhuang: "Because the competition for students is so fierce, some schools don’t run according to an educational law. Such a school, it tries to get funds through some improper means, and the per capita funding is the main source of funds for their school. Therefore, this will also have problems in system design, and this phenomenon will occur with some loopholes in supervision. "

　　Wang Jianzhuang believes that to completely change this situation, we need the joint efforts of the government, schools and other parties. While improving the quality of managers in secondary vocational schools, we should improve the funding system and methods, establish a mechanism to allocate funds to the extent that graduates serve the society, encourage the growth of high-quality secondary vocational education resources, and realize scientific development.

　　Wang Jianzhuang: "We use it to cultivate students’ other achievements, and its graduates serve the overall evaluation of society to allocate its funds in a planned way. For example, to evaluate a school and a secondary vocational school, there are 300 graduates this year. I will count the employment situation of your graduates through the graduates in the past five years, and I have an indicator of his contribution to the local economic and social development, and then I will give you the funds after this year in proportion, which is better. "

　　Voice of China will continue to pay attention to the progress of the follow-up investigation on this matter.

In the new energy vehicle market, the brand of Wenjie has gradually won the recognition of consumers by virtue of its technology and performance, but its design has become a hot topic among netizens. In particular, the design of M7 and M9 has been pointed out by many commentators that it is too high similar to other brands, which affects the uniqueness of brands and consumers’ willingness to buy to some extent. However, with the news of M8, it seems that Huawei has listened to the voice of the market and taken action.

The design team of Wenjie M8 has undergone a major transformation, aiming at creating an SUV with a more attractive appearance. The latest renderings show that the appearance design of the M8 is significantly different from the previous model, showing a more sporty and fashionable atmosphere, while incorporating futuristic elements. The front of the car uses a penetrating LED daytime running light, with a split headlight design, and the vertical light group below enhances the recognition of the car.

The side of the car body is simple and powerful, and the dense spoke rims add a sense of luxury, while the smooth window lines further enhance the overall elegance. It is reported that the positioning of the boundary M8 will be between M7 and M9, and the body size is expected to be between the two accordingly.

In terms of price, the M8 is expected to be located in the price range of M7 and M9. Considering the price of 249,800-329,800 yuan and the price of 469,800-569,800 yuan, it is estimated that the starting price of M8 may be more than 300,000 yuan, and the top version may be close to 400,000 yuan. This pricing strategy can not only avoid direct competition with M7, but also won’t occupy the market space of M9.

Although the rendering provides us with a general idea of the appearance of the M8, there are also some details that are not completely consistent with the previously exposed road test spy photos, such as the design of the door handle. The rear part continues the style of M9, and the through taillight has a "Xi" pattern, which implies its programmable characteristics.

In terms of power system, the M8 is expected to be available in both pure electric and pure electric versions, and its performance parameters are expected to be similar to M9, including strong power output and all standard air suspension.

Referring to the M9, its car model is 496PS/675Nm, which broke 100 in 4.9 seconds, and the CLTC pure electric cruising range is 225Km and 275Km. The pure electric vehicle model is the book data of 530PS/673Nm, which broke 100 in 4.3 seconds. The CLTC pure electric cruising range is 630Km, and the whole system comes standard with air suspension.

↑ Ask the interior real shot of M8 exposed.

As for the interior, the M8 follows the design of M9, and is equipped with a "triple screen" consisting of a 12.3-inch LCD instrument panel, a 15.6-inch central control screen and a 16-inch passenger entertainment screen, and a high-order intelligent driving system, which reflects Huawei’s technical strength in intelligence.

Generally speaking, the biggest highlight of the M8 is its brand-new design, which will greatly enhance its recognition and attractiveness in the market. With the disclosure of more information, we look forward to asking M8 to achieve better sales results in the future market.

　　On February 19th, thousands of anti-war activists in the United States held a rally in front of the Lincoln Memorial in Washington. Protesters demanded that the United States stop inciting the Russian-Ukrainian conflict and cut US military spending. The picture shows a protester holding a slogan to cut military spending to attend the rally.

　　The White House recently announced the fiscal year 2024 budget, and plans to allocate 842 billion US dollars for the US Department of Defense, which is the highest military budget ever proposed by the US government. In addition, the budget also plans to inject capital into defense-related projects in other departments.

　　Experts pointed out that the fundamental purpose of the high US military expenditure is to maintain hegemony. Supported by high military expenditure, the United States continues to disrupt the world and bring instability to the world. The uncertainty of the external environment has become the reason for the United States to further increase its military spending, which has led to the United States falling into the strange circle of "the higher the military spending, the less safe it is."

　　The highest military expenditure in peacetime

　　According to the news released on the website of the US Department of Defense, the US government’s 2024 budget proposed to allocate 842 billion US dollars for the Pentagon. This amount is $26 billion higher than the military budget for fiscal year 2023 proposed by the US government and $100 billion higher than that for fiscal year 2022.

　　"The US government’s military budget in 2024 hit a record high." Today, the Russian TV website reported that at present, the US military expenditure has exceeded the sum of the military expenditures of the nine countries ranked next.

　　Reuters reported that in addition to the $842 billion allocated to the U.S. Department of Defense, the new budget also plans to allocate $44 billion for defense-related projects of the FBI, the U.S. Department of Energy and other institutions, which will bring the total defense-related budget of the United States in fiscal year 2024 to $886 billion, which is the highest defense budget proposed by the U.S. government in peacetime.

　　The website of National Defense magazine reported that $886 billion is expected to account for 3.2% of the US GDP in 2024 and 47% of the US federal government’s discretionary expenditure.

　　American military spending has been the highest in the world for many years. According to the data of the Stockholm International Peace Research Institute in Sweden, during the 10 years from 2012 to 2021, the US military expenditure always ranked first in the world, accounting for 39% of the total global military expenditure in the past 10 years. In December 2022, the US House of Representatives passed the National Defense Authorization Act for fiscal year 2023, which stipulated that the US defense budget in 2023 was as high as 858 billion US dollars. This is the first time that US military expenditure has exceeded 800 billion US dollars.

　　McChord, Chief Financial Officer and Auditor-General of the US Department of Defense, recently told American media that the ratio of US military budget to GDP in 2024 is not the highest in history. The defense budget of the United States in the late Iraq war and Afghanistan war accounted for much more than 3.2% of GDP. He added that the US military expenditure during World War II once reached one third of GDP.

　　In order to maintain high military spending, the United States does not hesitate to empty its pockets. Recently, many foreign media have noticed that the financial health of the United States has declined. The national debt burden of the United States has now exceeded 31 trillion US dollars, far exceeding the total GDP of 25 trillion US dollars. According to the website of the US Defense News Weekly, Speaker of the US House of Representatives McCarthy promised to cut the federal budget by 130 billion US dollars to reduce the US debt burden, but neither the Senate nor the House of Representatives opposed the continued increase in military spending.

　　Reuters said that the US Congress will discuss the 2024 budget in the coming months. The US Congress may further increase military spending on the basis of the budget proposed by the White House.

　　"Still being false ‘ Hegemonic dream ’ Trapped "

　　According to the information published on the website of the White House, $842 billion includes $9.1 billion of targeted investment in the Pacific Deterrence Program of the US Department of Defense. The plan aims to strengthen the presence of the United States in the Pacific region. The new budget also proposes to provide $6 billion in aid to Ukraine. In addition, the new budget also stated that it would invest $2 billion to "make game-changing investments in the Indo-Pacific region".

　　In terms of weapons and equipment, the United States is also continuing to "burn money." Reuters said that the new budget proposed to invest a huge sum of US$ 145 billion in the weapons research and development program, specifically for developing long-range strike weapons such as hypersonic missiles and promoting the modernization of US military equipment.

　　The White House said in a statement that the 2024 military budget aims to "ensure American security" and strengthen cooperation with allies and partners to "meet urgent global challenges". Among them, "China" and "Russian" became the key words that frequently appeared in the statement.

　　"The fundamental purpose of the United States to maintain high military spending is to maintain its own hegemony." Yuan Zheng, deputy director and researcher of the American Institute of China Academy of Social Sciences, said that the United States has always believed in the law of the jungle in the diplomatic field, believing that military power is an important pillar of American global hegemony, and firmly believes that if it wants to maintain its hegemonic position and enhance its so-called ability to intervene in international affairs, it must increase its investment in military spending.

　　"In recent years, the United States has returned its strategic focus to the so-called ‘ Competition among great powers ’ , regard China and Russian as the main ‘ Challenge ’ And ‘ Threat ’ , hope in the face of ‘ Strategic opponent ’ At the same time, it maintained a strong military deterrent, so it continued to increase military spending, which made the US military expenditure increase obviously. At the same time, the United States continued to provide military assistance to Ukraine, which led to the decline of ammunition stocks in the United States, and it was necessary to purchase more ammunition to make up for the vacancy, further pushing up US military expenditure. In addition, the inflation factor also has an impact on the rise of military spending. " Yuan Zheng said.

　　"In today’s world, from the Russian-Ukrainian conflict, the Iranian nuclear issue to the South China Sea dispute, there are many conflicts and disputes behind the United States." Zhou Fangyin, vice president of Guangdong Institute of International Strategic Studies, said, "The United States has always regarded military hegemony as the core means to achieve strategic goals and hopes to seek other interests with military superiority. At the same time, the United States also hopes to enhance its allies’ confidence in the United States and maintain the US-led alliance system by increasing military investment. "

　　"The United States is still being falsely ‘ Hegemonic dream ’ Trapped. " Recently, Andrew Bacevic, an honorary professor of international relations and history at Boston University, published an article on the bimonthly website of American Diplomacy, saying that American foreign policy agencies insist that the world needs more American military forces, and the fiasco of the Iraq war and the Afghan war has not stopped the United States from "betting" on military operations. For decades, America’s military misjudgment has wasted a lot of American wealth and sacrificed the lives of thousands of Americans. According to Brown University’s "War Cost Accounting" project, since the "September 11th" incident, the United States has spent about $8 trillion on global military operations, and the costs of these military operations far outweigh the gains.

　　American military spending remains high, and there is a military-industrial complex behind it. Reuters reported that the 2024 budget of the United States was the first budget that explicitly proposed to sign long-term contracts with American arms dealers for the procurement of missiles and other ammunition. In the past, such long-term contracts were only used for the purchase of aircraft and ships. According to the report, the new budget will benefit major US arms dealers such as Raytheon, Lockheed Martin, Lockdyne, Northrop Grumman and General Dynamics.

　　Zhou Fangyin said that the military-industrial complex composed of the US military, arms dealers, politicians and think tanks has strong political influence in the United States. In recent years, despite the economic downturn, increasing financial difficulties, and unhealthy government revenue and expenditure, the United States has maintained high military expenditures, which has already damaged the economic growth and competitiveness of the United States. However, due to the lobbying and encouragement of the military-industrial complex, the US government refused to cut military spending even if it cut other expenditures.

　　"There has always been a call to cut military spending in the United States, but in the end it often ends in vain. Obviously, there are huge interest groups behind it." Zhou Fangyin said.

　　A dangerous signal.

　　High military expenditure continues to support the US overseas military operations. Some American media found that from 1798 to 2022, the United States launched 469 military activities overseas, and only 251 times in the short period of more than 30 years since the end of the Cold War, far exceeding the sum of more than 190 years before the end of the Cold War. The targets of these military operations involve most countries in the world.

　　Stimulated by the new round of high military expenditure, the US military plan is more active. According to the website of the US Defense News Weekly, the funds allocated to the US Department of Energy in the new US budget in 2024 will provide a "strong technical and engineering foundation" for the trilateral security partnership between the United States, Britain and Australia. A few days ago, the United States, Britain and Australia just announced a new nuclear submarine cooperation plan, and the nuclear proliferation behavior of the three countries has taken another dangerous step.

　　Yuan Zheng said that the United States believes in force and is obsessed with increasing military spending and enhancing its ability to intervene abroad. This concept violates the purposes of the UN Charter and the basic norms of international relations based on international law, and runs counter to the trend of world peace and development. At present, on the basis of its strong military strength, the United States is still increasing its expenditure on weapons research and development and procurement, and promoting the modernization of its military equipment, which is a dangerous signal to other countries. This move will stimulate the arms race, aggravate international tensions and undermine the global strategic balance.

　　"The United States has greatly increased its military spending, which has also made the relationship between major powers even more tense." Yuan Zheng said, "The United States regards China and Russia as its main strategic competitors, engages in proxy war behind the Ukrainian crisis, tries to bring down and consume Russia, and constantly uses the situation in the South China Sea and the Taiwan Strait to fully contain China. These acts seriously endanger regional peace and security and bring instability to the world, which is by no means a good thing for global strategic stability. "

　　In the new budget, the United States also proposes to "strengthen democracy and promote human rights on a global scale". To this end, the budget will provide more than 3.4 billion US dollars for "strengthening free and independent media; Combating corruption, strengthening democracy, and defending free and fair elections and political processes.

　　The bimonthly website of American Diplomacy published an article entitled "The Root of Washington’s Addiction to Force", saying that the United States has developed the inertia of interfering in international affairs. During the Cold War, under the banner of national security, the United States supported coups, intervened in elections and secretly took military action around the world. After the end of the Cold War, the old habits of the United States were still deeply rooted, and they began to call themselves "leaders of the free world" and continued to intervene under the banner of "protecting human rights and promoting democracy".

　　Zhou Fangyin said that the United States is currently caught in a vicious circle of military expansion. On the one hand, in the name of safeguarding world security, the United States has greatly increased its military expenditure and created contradictions and conflicts around the world. On the other hand, in order to intervene and intervene in these conflicts, the United States needs huge financial support, thus further increasing its military expenditure. For many years, the United States has been trapped in this cycle.

　　"Since World War II, the United States has always been the most powerful country in the world. If the United States really wants to promote world security, it can make achievements in many fields. However, the interest of the United States has never been to promote world peace and security, but to expand its international influence, suppress its strategic opponents and safeguard its global hegemony. As a result, it has not only added instability and uncertainty to the world, but also made the United States pay a high price. The United States has always believed that there are enemies and insecurity outside, so it has continuously strengthened its military investment, thus stepping into the strange circle of arrogance. " Zhou Fangyin said. (Reporter Lin Zihan)

　　On June 11th, the reporter learned from the People’s Government of Songbei District in Harbin that the investigation team of "Private Demolition of Load-bearing Walls" in Limin Academy Community invited nine national authoritative experts, including China Academy of Engineering, to form an expert group to make a special demonstration on the safety appraisal and repair scheme of the building structure, and formed an expert group’s opinion that the technical work procedures such as testing, monitoring, appraisal and repair scheme preparation are reasonable, the content is comprehensive, and the analysis and appraisal results are credible.

　　After the incident, Songbei District entrusted national and provincial authoritative professional institutions to comprehensively carry out related technical work such as building structure detection, deformation monitoring and structural safety appraisal, and formulated a repair plan.

　　First, the National Construction Engineering Quality Inspection and Testing Center of China Academy of Building Research was entrusted to carry out comprehensive inspection on Building B of Limin Academy Community, and 248 houses were checked one by one. After verification, the total number of vertical load-bearing wall members on each floor of Unit 2, Building B of Limin Academy Community is 50, with a total cross-sectional area of 42.98 square meters. In the decoration construction, part of the wall of one component was demolished, with a cross-sectional area of about 0.48 square meters, accounting for 1.12% of the total cross-sectional area of the load-bearing wall of this floor, and the other walls were non-load-bearing walls. The test results show that 248 houses in Building B have not found any stress cracks in structural members, and all the cracks that can be seen are located in the infilled wall or the interface with the structure, which does not affect the structural safety.

　　Second, the Heilongjiang Institute of Cold Building Science was entrusted to monitor the deformation of the building. The continuous monitoring for 30 days showed that the data of each monitoring point were within the allowable value of the national standard, and no abnormality was found.

　　The third is to entrust Harbin Institute of Technology Engineering Testing Co., Ltd. to carry out the safety appraisal of the building structure, which shows that the whole structure is safe and stable except for the structural members adjacent to the demolition site, and it can meet the requirements of safe use after repair.

　　Fourth, the architectural design and research institute of Harbin Institute of Technology was entrusted to make a restoration plan based on the appraisal report.

　　Recently, an expert group composed of nine national authoritative experts, including academicians of China Academy of Engineering, national engineering survey and design masters, main compilers and examiners of national general codes, conducted a special demonstration on the safety appraisal and repair scheme of structures after illegal demolition. The expert group conducted on-site investigation and listened to the special reports from the testing unit, monitoring unit, appraisal unit, original design unit and restoration design unit. After questioning and discussion, the expert group’s opinion was formed: the temporary measures taken against the illegal removal of shear walls were timely and effective, ensuring that the structure was in a safe and controllable state at the disposal stage; The technical work procedures such as detection, monitoring, appraisal, design calculation and analysis, and preparation of repair scheme are reasonable and comprehensive, and the analysis and appraisal results are credible; It is reasonable and feasible to adopt the standard not lower than that at the time of construction to implement the restoration.

　　After verification, the picture of the gables of the building passing through the big cracks in the network was previously transmitted, and the building of Building B in the non-Limin Academy Community was a network picture quoted from the media.

　　It is understood that the residents of Unit 2, Building B of Limin Academy Community have been temporarily resettled, and 15 working groups have been set up in Songbei District to ensure the residents’ living services, and the first-class construction enterprises in the province will be entrusted to start the restoration construction. Songbei Branch of Harbin Public Security Bureau took criminal compulsory measures against five people, including the lessees Zhang and Ma Mouxin, the constructors Chang Moujiu and Liu Mouping, and the manager of the property company Zhang, who were suspected of negligently endangering public safety by dangerous means. Zhu Mobin, the owner of the house involved, and the property company will be severely punished according to the upper limit. The case is currently under further investigation. The Supervision Committee of the Harbin Municipal Commission for Discipline Inspection has carried out investigation on the related problems existing in this incident.
