　　Recently, nine departments, including the Ministry of Agriculture and Rural Affairs, the Ministry of Housing and Urban-Rural Development and the Ministry of Transport, jointly issued the Notice on Strengthening the Prevention and Control of Red imported fire ants (hereinafter referred to as the Notice), and held the launching ceremony of the National Joint Prevention and Control Action of Red imported fire ants in Zengcheng District, Guangzhou. The red imported fire ant and its prevention and control have aroused widespread concern and become one of the hot topics discussed by people.

　　What kind of insect is red imported fire ant? From where? Compared with the familiar ants, what are their characteristics and harmfulness? At present, what is the spread and harm of red imported fire ants in China? What are the effective scientific prevention and control measures for red imported fire ants?

　　Fierce in nature, with great ecological harm.

　　Many Chinese people are undoubtedly strangers to red imported fire ants. Indeed, this insect, which originated in the border areas of Brazil, Paraguay and Argentina in South America, is an authentic alien invasive creature, and its popularity in society was not high before. As its name suggests, the red fire ant is red scorpion-colored, and its shape is similar to that of common ants, about 3 mm to 6 mm long. It looks unattractive and seems to have nothing special.

　　Nine departments in the State Council jointly issued a notice of interception and prevention, and launched nationwide joint prevention and control. The high-standard "treatment" of red imported fire ants in China shows that this insect is not only very harmful, but also difficult to prevent and control. Indeed, the Latin scientific name of red imported fire ant means "invincible ant", which reflects its great harm from one side. According to Professor Lu Yongyue, director of the Red Fire Ant Research Center of South China Agricultural University, the invasion of red fire ants will lead to serious ecological problems, destroy the normal production and living order, and it is very difficult to kill and prevent.

　　Specifically, the harm of red imported fire ants can be summarized as the following four aspects: First, it destroys the local ecological structure. Solenopsis invicta has strong adaptability. After invading a place, it often develops rapidly into a dominant population, which not only "exterminates" other types of ants in the place, but also exterminates beneficial insects such as spiders, causing great damage to the original ecological structure and serious ecological imbalance. The second is to reduce crop production. Solenopsis invicta directly feeds on seeds, fruits, buds, tender stems, rhizomes, etc. of crops, and transports and grazes honeydew-secreting pests such as aphids and scales to spread plant diseases and insect pests. These directly caused great losses to local agricultural production. Third, it threatens people’s health and even life safety. After being disturbed, the red imported fire ants will not only escape in scattered directions, but also have strong group aggression. By injecting venom into the victim’s skin through stinging, people who are allergic will have symptoms such as blushing, urticaria, and even difficulty breathing. Those with severe allergic reactions will have symptoms such as vomiting, dizziness and shock. If they are not treated in time, they may be life-threatening. The fourth is threatening public safety. Because red imported fire ants often invade outdoor and home nearby electrical equipment, such as electric meters, telephone switchboard, traffic signal cabinet, etc., it may cause short circuit of wires or facility failure, which may lead to public safety accidents.

　　It is precisely because of the serious harm of red imported fire ants that the media have quoted experts’ symbolic evaluation that red imported fire ants are "one of the 100 most dangerous invasive species recognized worldwide".

　　Three-dimensional communication is difficult to prevent and control.

　　Solenopsis invicta is not only harmful, but also difficult to control, which is largely determined by its species characteristics and the process of economic globalization.

　　The breeding speed of Solenopsis invicta is amazing, which increases the difficulty of killing. In the colony of Solenopsis invicta, the queen is the key role responsible for laying eggs and reproducing offspring. In some nests, there will be several or even dozens of queens, and each queen can lay 1,500 to 5,000 eggs a day. The number of Solenopsis invicta can increase greatly in a short time, resulting in an extremely large scale of ant colonies. Some nests may have as many as hundreds of thousands or even hundreds of thousands of Solenopsis invicta.

　　In a certain area, Solenopsis invicta can spread and reproduce in a three-dimensional natural way. Solenopsis invicta can spread to the neighboring areas through nest migration and nest division. Although the distance of each crossing is not large, after a certain period of accumulation, this slow and steady strategy can show the long-term effect of "attacking the city slightly". In addition, red imported fire ants can spread in the air for a long time in a short time. Male and female reproductive ants can mate at a height of hundreds of meters and land several kilometers away to start nesting, thus rapidly expanding new space. It is worth noting that the water flow not only can not achieve the effect of killing red imported fire ants, but also helps them to migrate across distances. Some red imported fire ants build their nests on riverbanks or low-lying places. With the flood coming, although their nests will be submerged, the ant colonies will form an "ant cutting" and drift with the water. When they meet a suitable nesting place, they try to go ashore to build their nests and live in a new place.

　　With the development of domestic unified market and the deepening of economic globalization and regional economic integration, there are more and more cases of red imported fire ants spreading through logistics and human factors such as objects and vehicles, and it is more and more difficult to prevent and control them. It is through international trade, especially international horticultural plants and agricultural products and the subsequent soil movement that red imported fire ants escape customs inspection and realize transcontinental and transnational transmission, and then continue to spread in a country in a similar way in areas suitable for survival.

　　The difficulty of prevention and control of red imported fire ants lies in its concealment in the early stage of invasion. The mature nest of Solenopsis invicta will form an obviously raised mound of sand, which is easy to be identified, but it is relatively hidden and difficult to be detected when it is first built. By the time it was discovered, its invasion had developed to a certain extent, which delayed the opportunity of governance and increased the difficulty of prevention and control.

　　Invasion of more than 16 years, urgent need to contain.

　　In late September, 2004, a serious ant was found in Wuchuan City, Guangdong Province. Lu Yongyue, as one of the experts, identified this ant as red imported fire ant through morphological identification and field investigation in Wuchuan, and confirmed that red imported fire ant invaded Chinese mainland for the first time. Related experiments show that the newly discovered Solenopsis invicta in Wuchuan has 100% homology with Solenopsis invicta from Florida, USA. The results of field investigation show that the occurrence density of Solenopsis invicta in some places, such as barren slopes, grasslands and ridges full of weeds, is high, which has adversely affected local agricultural production, people’s health and daily life. These findings provide an important scientific basis for early warning, prevention and rapid eradication of the invasion of red imported fire ants.

　　In January, 2005, the Ministry of Agriculture issued an announcement, officially announcing the discovery of fire ants in Wuchuan and other places, and including fire ants in the list of quarantine pests of imported plants and the list of quarantine pests of agricultural plants in China. At the same time, the Ministry of Agriculture issued the Emergency Plan for the Prevention and Control of the Red Fire Ant Epidemic (hereinafter referred to as the Emergency Plan), announced the four levels of the red fire ant epidemic and the corresponding response mechanisms, and determined the organization and leadership system suitable for the first-level response, such as establishing the inter-ministerial joint meeting system and establishing the red fire ant epidemic prevention and control headquarters. In addition, the Emergency Plan also stipulates that after the corresponding level of emergency response, relevant parties should immediately start to do a good job in epidemic situation confirmation, epidemic situation report, epidemic situation announcement, blockade control, prevention and control, epidemic situation investigation and monitoring, and entry-exit quarantine. In April and November of that year, the Ministry of Agriculture announced the epidemic situation of red imported fire ants in Hunan, Guangxi and Fujian.

　　Although some achievements have been made in the prevention and control work, due to the huge number of transmission vectors, especially in recent years, due to the increase in the number of goods transported and the suitable climatic conditions, the spread of Solenopsis invicta in some provinces and regions has accelerated and the epidemic situation has aggravated. At present, Solenopsis invicta has spread to 435 counties (cities, districts) in 12 provinces (autonomous regions and municipalities), with the northernmost part reaching the Yangtze River valley, Zhejiang and Jiangxi in the east and Guizhou, Chongqing and Sichuan in the west.

　　The "Notice" jointly issued by nine departments recently is the latest deployment on the prevention and control of the interception of red imported fire ants under the background that the Biosafety Law of People’s Republic of China (PRC) was passed and will be implemented on April 15th, and the practical measures to strengthen the management of alien invasive species according to law have been introduced, which can be said to be unprecedented.

　　Joint prevention and control, comprehensive management

　　Solenopsis invicta invaded Chinese mainland through imported goods. More than 300 batches of 17 kinds of articles intercepted at the entry port confirmed that waste articles (waste paper, waste electronic products, etc.) and logs were the main ways to carry Solenopsis invicta into China. The spread of Solenopsis invicta in China is mainly carried by turf and flower seedlings, and 27 of the 95 flower seedlings surveyed carry Solenopsis invicta. The incidence of red imported fire ants in turf plantation was 48.8%; Among the 122 introduced areas, the invasion rate of turf/seedlings was 85.2%.

　　The "Notice" grasps the two keys of external defense input and internal non-proliferation, and requires strengthening departmental coordination. Specifically, the Ministry of Agriculture and Rural Affairs, together with the Ministry of Housing and Urban-Rural Development, the Ministry of Transport, the Ministry of Water Resources, the Health and Wellness Commission, the General Administration of Customs, National Forestry and Grassland Administration, the State Railway Administration and the State Post Bureau, established an inter-ministerial cooperation and joint defense mechanism for red imported fire ants to organize and coordinate the prevention and control of interception. Among them, the customs directly under the customs are required to be responsible for organizing the monitoring of the port of entry, imported goods and articles and container storage areas, and notifying the port management department to carry out prevention and control; All customs should strengthen the inspection and quarantine of imported goods (seedlings, wood, forage, etc.), articles and containers from countries and regions where red imported fire ants occur to prevent the spread of the epidemic. The "Notice" requires strict quarantine supervision and law enforcement inspection, focusing on strengthening the quarantine of seedlings of crops with soil, seedlings with soil greening, lawn grass, etc. transported from counties (cities, districts) where the epidemic occurs. If the epidemic is found, it should be stopped. If it is really necessary, it can only be transferred after passing the quarantine treatment; The transportation, railway and postal departments are required to urge road freight transport enterprises, railway transport enterprises and express delivery enterprises to do a good job in the inspection of phytosanitary certificates for carrying or receiving related goods, mail and express mail in counties (districts) where the epidemic occurred, so as to ensure that they do not carry or receive without a license.

　　Emergency killing is an important aspect of preventing and controlling red imported fire ants. Lu Yongyue said that the red imported fire ant research center of South China Agricultural University, where he is located, has built a technical system for monitoring, quarantine and prevention and control of red imported fire ants suitable for southern China. In the aspect of monitoring, three kinds of bait and placement methods with good effects were screened out, and the monitoring accuracy was higher than 98%. In the aspect of killing, the contact toxicity of 18 insecticides to 4th instar larvae and the contact activity of 17 insecticides to worker ants were confirmed. Developed low-toxicity bait and waterproof bait containing more than 10 pesticides such as spinosad and avermectin, and formed supporting application technology; A highly effective pesticide for killing red imported fire ants was created and a matching application technology was formed, which solved the bottleneck problem that it is difficult to prevent and control in rainy season and low temperature season.

　　Spring and autumn are the active periods of Solenopsis invicta, and the best period to carry out centralized prevention and control actions. Experts believe that as long as all parties concerned work together to strengthen prevention and control in accordance with the requirements of the Notice, they will certainly be able to curb the spread of red imported fire ants, provide an important guarantee for the continuous and stable development of grain production and planting industry, and further build a national ecological security and biosafety barrier.

"Octagonal Cage" is showing, with a box office of more than one billion and a douban score of 7.5, which is far better than the last film directed by Wang Baoqiang. From making a scene in Tianzhu, which was rated as the most disappointing film by the Golden Broom Award, to becoming the most disappointing director, Wang Baoqiang has spent six years and new films to save his audience.

Born in the countryside, "Stupid Root" has worked hard to become a big star with diligence and hard work, and has always maintained a "grounded atmosphere" after becoming famous. This kind of character image is unique among domestic actors, and Wang Baoqiang can’t lose this label, which is the part that most conforms to the values of most ordinary people in his growth as a star.

Wang Baoqiang knew what he wanted from the very beginning, which coincided with popular perception. He is smarter than many star actors and has never been a "stupid root".

The birth of "stupid root"

Many stars play ordinary people and farmers in their roles, but Wang Baoqiang was born. Born in rural Hebei, his family was poor. He had never been to school before he was eight years old, but he went to Shaolin Temple to practice martial arts because he saw Shaolin Temple. Six years later, he drifted north and finally walked to the stage step by step.

In this process, Wang Baoqiang attaches great importance to polishing himself. In 2009, some media interviewed Wang Baoqiang’s master elder brother in Shaolin Temple, and got the evaluation that "Bao Qiang loves hardship and hates laziness". In the days of Shaolin Temple, he got up at five o’clock every morning to practice, and the training time was as high as eight hours. When ordinary people were still in primary school, Wang Baoqiang persisted in this way, and he was practicing while others were resting.

Because he started the dream of a star early, Wang Baoqiang knew that learning more would be useful for making movies in the future. When he first went to Shaolin Temple, he wanted to learn routines and weapons, rented cameras and bought films, and spent more than half a month’s living expenses without feeling distressed. He also knew that "taking pictures was for being famous as an actor for information" … In those years, he was a "madman" who dreamed of a star all day long in the eyes of almost all senior brothers.

After the accumulation of Shaolin Temple was completed, Wang Baoqiang began to take action to find opportunities in Beijing. I lived with five people in the courtyard next to the coal yard. In order to find a job conveniently, I pooled my money to buy a BP machine with digital display. Run a group while working; When I went to the North Film Factory as a group performance, I didn’t eat all day. I was so hungry that I ate five steamed buns in one breath and didn’t dare to drink water. "I was afraid that I would swell to death immediately."

But in a later interview, he said that even if life is hard, there is hope.

It has been reported by the media that because of the low level of education, all the lines are turned to the dictionary for phonetic notation, while other actors are shooting a scene to memorize the lines of a scene, and Wang Baoqiang memorizes all the lines in advance. "When I was not famous, I was said to be embarrassed, and I said everything."

But hope still came to him. Li Yang, the director who was called a noble by Wang Baoqiang, made him star in the independent film Blind Well. When he mentioned the advance payment from 500 yuan at first, Wang Baoqiang still trembled with excitement. It was a lot of money for him in 2002, but more importantly, this film won him the Golden Horse Award for Best Newcomer, and the career of Wang Baoqiang actor finally officially started.

In 2004, Wang Baoqiang became the "silly root" in world without thieves directed by Xiaogang Feng. Such a funny and simple character, who seems to have a dull brain, can be remembered by the audience at once, and also makes Wang Baoqiang a "stupid root". According to media reports, Wang Baoqiang, who became famous in 2006, still wants to go home to harvest corn-his public image is very clear, simple and hard-working, which fits people’s imagination of "stupid root".

At that time, Wang Baoqiang said that after filming this play, he knew that he would never worry about filming in his life, but he didn’t understand how to break through the audience’s impression of himself later. "Can you only play such a role in your life?"

Smart "stupid root"

While worrying about his career as an actor, Xiaogang Feng woke him up. "He told me that if you want to play a role that others can’t play, you Wang Baoqiang is unique, and you don’t have to pursue those Gao Fushuai things that others say. Eat this bowl of rice well first, let the audience accept it first, and then slowly you seek change."

It is true that if Wang Baoqiang after "Stupid Root" is a villain or a fashionable urbanite in the movie, it is difficult for the audience to remember his image as an "honest man". "The audience doesn’t know me, so they ruin their own way, because I haven’t set a foundation for acting yet." If the private life of Wang Baoqiang, who became a star, is rich and luxurious, the audience will also find it unacceptable.

Wang Baoqiang is very clever about this. He is not in a hurry to lose his label like many stars. Wang Baoqiang was once asked by the media, do you feel that your value lies in maintaining your true colors? If I let you go to college, do you like it? His answer is: "I don’t keep it. This is my true nature and I can’t change it."

So later, Wang Baoqiang starred in Xu Sanduo in Soldier Assault and in the plot against him.blind personAnd My Brother’s Name is Shun Liu. These characters are almost tailor-made for his image, which makes him consolidate his audience base. "I am willing to go to college, and I am afraid that people will not want me. I especially want to study literature, because literature is particularly helpful for writing scripts and creating. " After becoming famous, Wang Baoqiang was no longer confused and knew what was useful.

In 2011, he starred in Hello! Mr. Tree once again won him the recognition of the award, but it’s seven years since "Silly Root", and it’s time to make a change: In 2012, Wang Baoqiang’s "Too Bad for People to Embarrass" strongly refreshed the box office of domestic movies at that time, which opened a new era of high box office for commercial comedies different from "world without thieves", and Wang Baoqiang’s road to box office was thus opened.

But before that, he chose to star in Jia Zhangke’s Destiny. "Embarrassed in Thailand is very successful. Everyone likes the role of baby very much, but it is hard to surpass it in comedy, so I want to change my image and try different styles and roles." Even if there are other plays to pick up, he doesn’t want the audience to fix his aesthetics.

In 2015, Wang Baoqiang starred in the first film of detective chinatown, and the box office of the film was still good. As an important actor in commercial films, after working with directors such as Xú Zhēng and Chen Sicheng, Wang Baoqiang also wants to make his own films. "I want to be like them." At the launch conference of "Make a scene", Wang Baoqiang said.

In the media reports at that time, Wang Baoqiang said that in 2016, he abandoned everything, hollowed himself out, and put all the skills he had learned before filming into use, and finally made this film "Make a fuss". However, although the film got more than 700 million box office, the word-of-mouth completely collapsed.

In the ultra-low evaluation of the film Douban 3.7, "Your baby really can’t afford this sympathy score" and "This film proves that the director still has a threshold", and so on are everywhere. Because of this film, the audience base on which it was supported was loosened, and the voice of "Wang Baoqiang playing the fool" began to appear in public opinion, and the crisis came.

Stop playing the fool

Wang Baoqiang went to receive the "Golden Broom" award, which has never been won by a star, and delivered a sincere acceptance speech: "The Golden Broom is not a glorious award, but it can spur you to progress. I love movies, I also respect movies, respect the audience, and respect all the seniors present. I owe the audience an apology. This time, I owe the audience once. In the future, I will continue to study hard and become a more qualified director in everyone’s mind. "

As a director, some people have a high starting point and a high probability of success. Wang Baoqiang doesn’t have Xú Zhēng’s humor or Chen Sicheng’s business ability, but his advantage is that, just like his belief that he will become a star at the beginning of martial arts, his bottom values are still the same as those of most ordinary people: hard work is very important, and hard work can change his destiny.

He began to throw away "pretending to be crazy and selling stupidity" and "stupid roots" to find the audience. "At that time, I let the audience down. I was very guilty and very sorry for the audience. I said I would make a good movie for the audience in the future, and I will do it. So I put everything down and did it in six years. " During the publicity period of "The Octagonal Cage", Wang Baoqiang told many media that the good movies that were owed to the audience in those years should be returned this time.

Up to now, Wang Baoqiang has not appeared in many works, and the script of "In the octagonal cage" has been polished for more than three years. However, because of the poor reputation of the first work, it is not so easy for even the big star Wang Baoqiang to invest in the new work. In the media reports, he said that he could not afford to lose when he became a director for the second time. "I used to fall, but I can still stand up. Now at this age, I am very nervous. I would rather not do it. If I do it, I can’t finish it in a hurry."

Wang Baoqiang was really afraid that the audience would stop believing him. There is a poster in the film, which emphasizes in large letters: Please believe it! Wang Baoqiang!

Now "In the Octagonal Cage" is released, with good reputation and box office, and Wang Baoqiang has once again verified his national foundation. But carefully, the story told in this film is more like a review and emotion of his "stupid root" career and grassroots origin. The simple characters and words in the film echo the starting point of his star road again-the audience still loves "stupid root" narrative and likes stars not far from themselves.

It’s just that Wang Baoqiang doesn’t need to play the fool anymore. Even so, he can always be the "silly root" in the audience’s mind.

　　September 10, TrumpchiThe E8 series welcomes a new member – E8 +. There are two models of the new car, the "MAX +" version is priced at 232,800 yuan, and the "Longteng +" version is priced at 238,800 yuan. The new car enjoys a national trade-in subsidy of 20,000 yuan, a replacement subsidy of 10,000 yuan for car companies, a 3-year 100,000-kilometer vehicle quality assurance, and a lifetime quality assurance for the first owner of Sandian. Trumpchi also provides additional rights for car buyers, mainly adding to the "refrigerator + color TV" that is most concerned by home users.

　　In this E8 + listing, GAC Trumpchi handed over the new car listing activity to Internet companies, and combined with the two IP activities of ByteDance, Wanyou attractive force festival and city life festival, to amplify the sound volume and "play together" with young people.

　　With this new launch, the user experience has been significantly improved. Intelligent voice expands the voice of the four-tone zone, and the second row can also be controlled; the speaker is upgraded to 9, and the surround sound effect is fuller. iSPACE has launched 2 new usage scenarios, including nap mode and movie viewing mode; the car Autonavi map supports traffic light countdown; pre-installed QQ music, Migu video and other APPs, richer entertainment. In terms of intelligent driving assistance, 4 front radars have been added, and the distance of roadblocks is accurate to millimeters; BSD blind spot monitoring has been added, and the information of approaching cars from the side can be grasped at the first time; equipped with ASTC eagle claw system, and optimized braking, so that emergency braking does not nod.

　　This time, the invisible places are also worth paying attention to.

The reporter learned that after the E8 +, the E9 will join the Huawei Supercharge Alliance and plans to launch the Supercharge version in the fourth quarter, becoming the world’s first plug-in model equipped with 4C Supercharge.

　　At this year’s Beijing Auto Show, GAC Trumpchi released the "Trumpchi Huawei Joint Innovation Plan". GAC Trumpchi revealed that it will release the blockbuster concept car and technical advantages of the plan at the end of September, and the three cooperative models will be launched next year.

　　Review:

　　At present, China’s auto industry is in the era of a hundred schools of thought contending. Each auto company is making breakthroughs and innovations in its own field and in its own way, and jointly driving the entire industry towards a more intelligent and electric direction. This is an endless marathon that requires more new car launches and more car companies to participate.

　　Guangzhou Daily New Huacheng Reporter: Zhou Weili

As a new brand and model, this ultra-Yue 01 is more concerned about its internal working materials. Today, we will take this car apart and find out from the anti-collision beam.

Skin material

Four-door aluminum alloy

The front and rear door skins of this car are made of aluminum alloy, and the rest are stamped steel plates.

The hood is a double lock structure commonly used in luxury cars, which is more secure.

Front collision beam

aluminium alloy

Remove the front bumper, and there is an aluminum alloy front anti-collision beam inside, with a thickness of 4.15mm and a width covering 76.04% of the front of the car. Do you think this anti-collision beam is familiar? Yes, it is very similar to the polar krypton 001 we dismantled before, but it is a little thicker.

The cross sections of the front collision beams of the two cars are exactly the same, both of which are in the shape of "mesh" with energy-absorbing folds in the middle, which is a feature of Geely’s vast platform.

Although the car is driving with pure vision technology, it has not cancelled the millimeter-wave radar, so three millimeter-wave radars can be seen on the bumper. There is also an UWB(Ultra Wide Band Ultra Wide Band) module on both sides of the bar skin, commonly known as the digital key module, which can realize the functions of unlocking the Bluetooth key of the mobile phone and unlocking the adjacent door.

This car, like Krypton 001, has an active air intake grille under the collision beam.

Like all vast platform models, there is a bearing bracket in front of the top of the tower on both sides of the engine compartment.

Shotgun extends forward from the A-pillar and is connected with the longitudinal beam, which belongs to the collision strategy of "hard shoulder".

The front energy-absorbing box is very long, which is another remarkable feature of Geely’s vast platform.

The length of the front energy-absorbing box is close to 50 cm, which has reached the position of the front suspension shock absorber and is connected by four bolts. This super-long energy-absorbing box can be regarded as a part of the front longitudinal beam, which can play a strong buffering role in actual collision. Even if the accident is bigger, it can be replaced directly to avoid cutting and welding of the longitudinal beam.

Rear impact beam

Single-layer stamped steel plate

Like Krypton 001, the rear anti-collision beam is a single-layer stamped hot-formed steel plate with a thickness of 1.04 mm, which can cover 62.50% of the rear of the car.

The rear energy-absorbing box is relatively regular. Like Krypton 001, it has not only collapsed folds, but also collapsed holes.

Like Krypton 001, the rear anti-collision beam does not protrude from the tailgate. If a low-speed rear-end collision occurs, the tailgate is easily injured.

summary

Even the names are similar.

The front and rear anti-collision beams of this Extreme Yue 01 are basically the same as those of Extreme Krypton 001, and the front aluminum alloy is hot-formed into section steel, which belongs to the level of materials needed at this level. Although many cars under Geely Group are the vast platforms of SEA, there are still differences in detail design and materials for cars of different grades and prices. Through disassembly, it is obvious that this polar cross 01 is closer to polar krypton 001, and even the name is similar.

So what about the chassis of this ultra-01? Please continue to pay attention to the subsequent contents of car dismantling. (The conclusion of the measurement data in this article and the video is only responsible for this car, and the measurement data is responsible for the publicized experimental method. )

Scoring of 2023 Extreme Crossing 01 Anti-collision Beam

Whose wishful thinking is "996 working system"?

Background:Recently, there was a news in the programmer world that someone launched a project called "996.ICU" on the well-known code hosting platform GitHub to resist the 996 working system. This move was immediately responded by a large number of programmers. The so-called 996 refers to working from 9: 00 am to 9: 00 pm every day, and "996.ICU" means "working 996, sick ICU".

China Youth Daily published its opinion:In the legal sense, the legitimacy of the 996 working system is obviously in doubt. It directly converts overtime work into normal working hours for employees, and even wraps this mechanism with words, giving it some cultural and moral colors. For example, those who are willing to accept are regarded as active, enterprising and have dreams, while those who are not active in cooperation may be reprimanded as greedy for comfort and muddling along. In this context, it is almost impossible for individuals to say "no" to this mechanism. It is said that if you don’t accept the 996 working system, you can jump to other industries. Not to mention that this statement avoids the legitimacy of employees’ rights protection, and also ignores that today’s 996 working system is not only a unique phenomenon of Internet startups, but is spreading to more industries. This phenomenon should inspire the labor inspection department to pay more attention and intervention. According to a survey conducted by China Academy of Social Sciences, the average leisure time in Chinese in 2017 was only 2.27 hours. Comparatively speaking, the average leisure time of nationals in the United States, Germany and other countries is about five hours per day, which is more than twice that of Chinese. According to statistics, the prevalence rate of depression in China is 6.1%, and the incidence rate is increasing year by year in recent years … Young people need to struggle, but it is not necessarily a blessing that more and more young people are busy in society "like machines with alarm clocks set". Reducing stress for young people does not only mean reducing their working hours, nor is it just the responsibility of a certain industry or enterprise. It is time to face up to how to decompress young people from the social system level. The rebound of the 996 working system is only an early warning.

Xiaojiang random thoughts:For example, what should I do if I need 10 people to do the work and only find 5 people to do it? Naturally, I can only work overtime. For those who work, the work overload is obvious. For employers, it is "getting twice the result with half the effort". Therefore, whether overtime is the norm and no overtime pay is given, whether it is beautified as corporate culture or dedicated, the essence behind it is that the boss is playing the wishful thinking of saving costs and squeezing employees. As far as the 996 working system faced by many programmers is concerned, there is still a so-called "deserved"-programmers usually have higher income, and "high income naturally bears high pressure". This kind of rhetoric is very confusing. But after careful analysis, the flaw comes. On the one hand, the programmer’s salary is higher because the output value of the high-tech industry is higher; On the other hand, not everyone can do it, and excellent programmers are "rare." In short, the programmer’s high income does not come from the boss’s "gift", but from market pricing. How can high income be a reason for infringing on labor rights and interests? The "overtime culture" also has a strong flicker, comparison and infectivity. For example, look at people’s "well-known enterprises" are so hard, what is the reason why "start-ups" don’t work hard? "Senior talents" dare not slack off. "Ordinary you" miss by going up one flight of stairs. Why are you so embarrassed? On the contrary, the above words turn enterprises and employers into the only way for workers to "succeed", which makes people stunned and must be vigilant! On the issue of labor rights protection, trade unions at all levels, labor rights protection departments,Do it when you should. This is the responsibility, the inevitable requirement of regulating the market, and the proper meaning of governing the country according to law. From a broader perspective, China’s economy has shifted from a high-speed growth stage to a high-quality development stage. High-quality development involves not only ecological protection, but also people-oriented.

　　A few days ago, the Nihon Keizai Shimbun observed that many countries are stepping up their arms procurement due to the conflict between Russia and Ukraine. Eastern Europe, the Middle East, North Africa, East Asia and other regions with severe security environment actively introduce new weapons. The supply of weapons in developed countries such as the United States and Europe is limited, and some emerging arms exporting countries have begun to rise.

　　The military trade market has always been the "wind vane" of the game between big countries and the "barometer" of the international security situation. In the past year, with the increasingly active military trade market, the already turbulent international situation has become more complicated. The New York Times reported that the expansion of arms trade highlights the escalation of global tensions.

　　The international military trade market heats up.

　　According to the annual report released by the Stockholm International Peace Research Institute in Sweden, in 2022, global military expenditure exceeded $2 trillion for the first time, of which the United States accounted for 38%. In terms of the proportion of global military expenditure, the United States and its NATO allies together account for 55% of global military expenditure. If you count America’s allies in the Pacific, Australia, Japan, New Zealand and South Korea, the figure rises to 61%. It is worth noting that the military expenditure of the United States alone exceeds the sum of the military expenditures of other countries in the top ten.

　　"Nihon Keizai Shimbun" reported that many countries are stepping up efforts to introduce American weapons: Lithuania, which borders Russia, decided to purchase eight sets of "Haimas" rocket launcher systems from the United States at a price of 495 million US dollars; Belgium signed a contract with the United States to purchase air-to-air missiles capable of carrying the latest fighters. Based on the new National Security Strategy, Japan will introduce Tomahawk cruise missiles from the United States. As a supplier of weapons, the US defense industry began to increase production.

　　All along, the United States has firmly occupied the first place in the world’s military trade. According to the data released by the State Council on January 25th, in fiscal year 2022, the total foreign arms sales of the US government authorized by the State Council jumped to about $51.9 billion, a surge of 49.1% compared with the previous fiscal year. In fiscal year 2022, the total authorized value of weapons and military equipment directly sold by US defense contractors to other countries and regions was about US$ 153.7 billion, up 48.6% from US$ 103.4 billion in the previous fiscal year. By the end of fiscal year 2022, the total number of entities registered to engage in defense trade activities in the Defense Trade Control Bureau under the State Council reached 14,445, which was also an increase compared with the previous fiscal year.

　　Under the coercion and inducement of the United States, NATO members have further increased their defense budgets. According to the European edition of Political News Network, France’s expenditure increased by 7.4% year-on-year, with the goal of reaching 2% of GDP by 2023. Britain and Poland, which have exceeded this line, are seeking to increase their defense budgets to 2.5% and 3% of GDP. Belgium, the Netherlands, Romania and the Baltic and Nordic countries all announced plans to increase military expenditure to at least 2% of GDP. The "laggards" in southern and western Europe have also accelerated their pace, and Spain’s defense expenditure will reach 2% of GDP in the next few years.

　　On November 21 last year, the 27 member States of the European Union reached an agreement to increase the military budget by 70 billion euros, and the European Union was responsible for the integration of military weapons procurement. Prior to this, Japan announced that it would increase its defense budget to $318 billion in the next five years.

　　In October last year, the list of the top 100 military enterprises in the world in 2021 published by a foreign website showed that the total military revenue of the top 100 enterprises reached 595 billion US dollars, an increase of 7.9% over the previous year. This data has maintained growth for six consecutive years, continuously refreshing the record of the total revenue of the top 100 military products. On the list, the sales of military products such as South Korea and Turkey, which are listed as "emerging military industries", have increased significantly.

　　"In this wave of military purchases, the supply and demand structure has undergone subtle changes." Zou Zhibo, deputy director of the Institute of World Economics and Politics of the Chinese Academy of Social Sciences, said: First, the buyers of military purchases cover a wide range. The countries that buy arms include not only the allies of the United States, but also other small and medium-sized countries, involving vast areas such as Eastern Europe, the Middle East, North Africa and East Asia. Second, the sellers of military purchases have also changed. In the past, the United States and Russia were the main sellers of global weapons, but because the United States wanted to support Ukraine and its own stocks, Russia had to fully deal with the Russian-Ukrainian conflict. The supply of weapons in the United States and Russia was greatly affected, and buyers turned to other countries that could export advanced weapons. The global military trade pattern has undergone major adjustments.

　　Insecurity is everywhere.

　　"In the past three years, affected by the COVID-19 epidemic, the global military trade showed a downward trend. With the improvement of the epidemic situation and the outbreak of the Russian-Ukrainian conflict, the international military trade market has shown an upward trend. " Guo Xiaobing, director of the Arms Control Research Center of China Institute of Contemporary International Relations, told this reporter, "At present, the global arms purchase tide mainly presents three characteristics: First, the contradiction between supply and demand has changed. In the past, there were more sellers and fewer buyers in military trade. Now, the demand suddenly becomes very strong and the supply becomes tight. Second, western countries, especially some NATO members and Japan, have increased their military spending significantly, becoming major arms buyers; Third, as far as the supply side is concerned, in addition to the particularly hot US arms business, the performance of some emerging arms exporting countries such as South Korea and Turkey in military trade is also eye-catching. "

　　"The outbreak of the Russian-Ukrainian conflict is the most serious geopolitical conflict since the Cold War, which has a major negative impact on the regional and global security situation." Zou Zhibo said that the United States and some western countries are not only the instigators of this conflict, but also participants. The United States and some western countries continue to increase their support for Ukraine’s weapons level, while Russia vows that it will never accept a failed outcome. Therefore, the uncertainty of this conflict is gradually increasing, and the trend of escalating regional tensions is also increasing. At the same time, in this conflict, the civil infrastructure, including the "Benxi 2" pipeline, was attacked, and the scope of the conflict expanded uncontrollably, which made countries generally worried about the safety of their own civil infrastructure and the demand for protection infrastructure rose sharply. In this situation, the insecurity of small and medium-sized countries has generally increased, and it is urgent to introduce new weapons to seek self-protection.

　　"Nihon Keizai Shimbun" reported that the momentum of expanding ground equipment in many European countries near Ukraine is also obvious. After the cold war, Germany has been reducing the number of tanks, and now it has begun to increase production again. Eastern European countries are promoting the procurement of large artillery such as howitzers. Lithuania, one of the three Baltic countries, has 30% more howitzers than the previous year. Countries such as Poland have begun to import tanks, self-propelled artillery and other ground equipment from South Korea.

　　As the world’s largest arms seller, the United States is the biggest driver of the global arms purchase tide. The State Council’s surge in direct commercial arms sales is mainly attributed to the United States’ support for Ukraine in the Russian-Ukrainian conflict, and claims that arms transfer and defense trade are important tools of American foreign policy.

　　"The United States manipulates the international situation through military trade and thus maintains its global hegemony." Zou Zhibo analyzed: First, military trade is an important starting point for the United States to implement its foreign policy. Who to sell weapons to, what weapons to sell and how many weapons to sell are the starting points for the United States to influence geopolitics and control the regional situation, and are the means for the United States to safeguard its global and regional interests. In this way, the United States can interfere in other countries’ internal affairs, exert strong pressure and even subvert other countries’ political power. Second, U.S. military trade has become a booster that intensifies turmoil and conflicts in the global region. The United States has a wide range of foreign military trade, selling arms to about 100 countries. The arms trade category covers rifles, tanks, warships, missiles and various types of fighters. These weapons with many varieties and huge quantities spread all over the world, which intensified the global confrontation conflicts and caused countless human tragedies. Third, the United States’ foreign military trade is right and wrong, as long as it is beneficial. The export of weapons to foreign countries should adhere to the principle of enhancing the defense capability of the receiving country and contributing to the construction of regional security. However, American foreign military trade completely ignores these principles and blindly pursues interests.

　　"The escalating Russian-Ukrainian conflict is the most direct driving factor for the surge in US arms sales; Expanding arms sales is one of the ways for the United States to seek economic growth after the economic recession; The military-industrial complex is the root cause of the surge in US arms sales. " Guo Xiaobing believes that the US military trade "hands over the knife" and "arches the fire", taking advantage of chaos to make profits, exacerbating regional conflicts and camp confrontation.

　　The overall risk of conflict has increased.

　　From February 17th to 19th, the 59th Munich Security Conference was held in Munich, Germany. The Munich Security Report 2023 released before the meeting emphasized that the world is entering a crucial decade for the future international order. According to the Munich Safety Index released at the same time, the world has entered a new stage where insecurity is everywhere.

　　"Military trade activity is a mirror reflecting the global security situation, and the two are inversely related. At present, the global tide of arms purchases has risen again, reflecting the changes in the current international security pattern and the deterioration of the security situation. " Zou Zhibo believes that the tide of arms purchases reflects the characteristics of the times when the world has entered a great change in a hundred years, reflects the efforts of countries to strengthen strategic autonomy and security autonomy, and highlights the sense of insecurity when the world is facing a nuclear threat. On February 6, 2023, UN Secretary-General Guterres issued a warning at the UN General Assembly, "We are at the most serious moment of nuclear war in decades".

　　India’s domestic carrier aircraft landed on the aircraft carrier for the first time, Russia plans to develop UAV air command post, Europe plans to jointly carry out "future air combat system" cooperation, Britain accelerates the integration of artificial intelligence and armed forces, Israel launches new smart missiles, Turkey’s new UAV first taxi test, and the United States develops a new generation of strategic bomber & HELIP; … Taking stock of the military "news" in 2022, it is not difficult to find that with the worldwide defense investment rising, the military trade market continuing to be active and the competition escalating, countries have rushed to the digital track of cloud computing, Internet of Things and big data to compete for the commanding heights of military science and technology development.

　　"In recent years, the international situation has been turbulent and international relations are complicated. Compared with a long time after the end of World War II, the cold war mentality and arms race have become more and more intense in the whole international relations. The overall rise in the risk of global conflicts has directly triggered a hot situation in the global military trade market. " Guo Xiaobing said that the global boom in military trade will not only further increase the risk of conflicts in already tense areas, but also further intensify the momentum of group confrontation.

　　"In the special historical stage when the world has entered a century-long change, and in the dangerous period of confrontation and conflict among big countries, the international community should attach great importance to the severe security situation and development trend, and make great efforts to resolve the dangerous situation and eliminate potential safety hazards." Zou Zhibo believes that, first of all, we should build consensus, enhance the sense of community of human destiny, be highly vigilant and jointly oppose the hegemonic acts of some countries that uphold the Cold War mentality in an attempt to safeguard their own interests by provoking division, confrontation and war; Second, establish a summit mechanism for big countries. Great powers should establish a global security governance mechanism, communicate and negotiate on major issues such as world affairs and concerns of major powers, and try their best to eliminate misunderstandings and resolve contradictions; In addition, reform and improve the United Nations security system and mechanism, uphold the principle of collective security and the spirit of multilateralism, and enhance the voice of developing countries and the efficiency of the United Nations in solving security problems. The perfection of the United Nations collective security mechanism should focus on adjusting the scope of application, reforming the organizational mechanism and strengthening its flank construction.

Xinhua News Agency, Beijing, May 10 (Reporter Wei Yukun) Recently, an executive meeting was held in the State Council to clarify policy measures, and strive to basically cancel the provincial toll stations of expressways nationwide by the end of this year, so as to facilitate people’s travel and improve logistics efficiency. In this regard, the relevant person in charge of the Ministry of Transport said at the routine briefing on the State Council policy held on the 10th that the Ministry of Transport has set a specific timetable to ensure the realization of this goal and task as scheduled.

Dai Dongchang, vice minister of the Ministry of Transport, said here that the cancellation of provincial toll stations on expressways is a very complicated systematic project, which involves a lot of work. The specific time schedule is to issue various plans and requirements, including technical standards, overall design plans, engineering construction plans and so on, before the end of May. The construction of the project will be completed from June to October, including the renovation of toll lanes, the renovation of toll stations, the upgrading of software and hardware, and so on. In November, the joint debugging test was started, so as to meet the requirements for switching between the old and new systems before the end of December. On this basis, timely organize and implement system switching to ensure the completion of this target task.

Dai Dongchang said that around the goal of basically canceling the provincial toll stations of expressways by the end of this year, work will be focused on four aspects.

First, speed up the construction and improvement of expressway toll collection system. It mainly includes: clearing and settlement at the central and local levels, upgrading the operation management system, standardizing the construction and transformation of hardware and software of toll stations, toll lanes and ETC portal systems, and strengthening the system network security.

The second is to speed up the popularization and application of ETC electronic toll collection system. The cancellation of provincial toll stations is not the cancellation of highway tolls, but the realization of fast toll collection without stopping through technical means. Therefore, the popularization of ETC is very important. To this end, it will speed up the installation of ETC vehicle-mounted devices for existing vehicles free of charge, promote the front-mounted installation of vehicles, expand service functions, encourage the application of ETC in car-related places such as parking lots, and realize the sharing of motor vehicle registration information to facilitate the installation of ETC vehicle-mounted devices for vehicles.

The third is to revise and improve laws and regulations. The abolition of provincial toll stations on expressways is a change in the national expressway operation mode and toll technology route, and it is urgent to revise and improve the highway law and toll road management regulations. In addition, it is also necessary to study and unify the highway traffic management policies for dangerous chemicals transport vehicles and motorcycles.

The fourth is to promote the stock of government toll roads in bond swap. In order to prevent and resolve the debt risk of toll roads, we will cooperate with relevant departments to increase the issuance of special bonds for toll roads, promote local government bonds to replace the existing debts of government toll roads that meet the policy requirements, optimize the debt structure, and prevent and resolve debt risks.

Vehicle-to-Everything (V2X) is a technology that allows cars to communicate with other devices, systems and services in the surrounding environment. This communication can be realized through wireless networks, including the connection between vehicles and other vehicles (V2V), infrastructure (V2I), pedestrians (V2P) and cyclists (V2B). In addition, it can also communicate with Internet service providers (V2N) and other IOT devices.

The main functions of the Internet of Vehicles include:

1. Real-time traffic information: Through communication with other vehicles and infrastructure, real-time traffic information can be obtained, which can help drivers avoid congested road sections and save time and fuel.

2. Safety enhancement: The Internet of Vehicles can help improve road safety, for example, by detecting the emergency braking of surrounding vehicles and reminding drivers to take corresponding actions.

3. Navigation optimization: Combining real-time traffic information and map data can provide more accurate route suggestions for drivers and avoid getting lost or detouring.

4. Entertainment and information services: The Internet of Vehicles can provide various online services, such as music, news and weather, as well as the ability to connect with other devices, such as charging mobile phones and controlling home equipment.

5. Vehicle maintenance and diagnosis: Through communication with vehicles, vehicle networking can monitor the performance and health of vehicles, warn potential problems in advance and reduce maintenance costs.

6. Autopilot support: The Internet of Vehicles can provide key information input for autonomous vehicles, such as road conditions, traffic signals and pedestrian information, and improve the safety and reliability of autonomous driving.

Generally speaking, the Internet of Vehicles is a very useful technology, which can improve the driving experience, safety and efficiency, and lay the foundation for future intelligent transportation systems and self-driving cars. However, to realize these functions, it is necessary to widely deploy relevant infrastructure and technical standards, which still faces some challenges.
