This newspaper has launched the column @ Dragon Boat Festival Moment from now on, focusing on the wonderful moments of celebrating the Dragon Boat Festival holiday in all parts of our province. Please make a note.

　　Anji dragon boat race between mountains and rivers

　　Zhejiang Online June 23rd (Reporter Li Shichao Sharing Alliance Huzhou Xuchao)On the afternoon of 22nd, the Dragon Boat Race of the 5th National Fitness Festival in Huzhou in 2023 was held in Fu Shi Cun, Xiaofeng Town, Anji County. Eleven dragon boat teams from all over Huzhou competed fiercely, attracting a large number of spectators to watch the race.

　　"Knock, knock …" With the sonorous sound of drums, the dragon boat players struggled to paddle in unison. Dragon boats rush out of the starting point like arrows leaving the string, and you chase after me and cut the waves, putting on a good show of "speed and passion" on the water. The exciting competition also ignited the enthusiasm of watching the game on both sides of the strait, and the cheers and cheers came one after another, which was very lively.

　　"Every year, I will participate in the Dragon Boat Festival. This year, there is an Asian Games, which feels very different." After the game, Lu Hongquan, a member of Shuijingjing Nanxun Dragon Boat Team, said.

　　Shi Cun is endowed with rich landscapes and pleasant scenery. "With the unique natural resources, we have been unable to find a transformation path, and the village collective income has always been very single." Zhang Wenze, secretary of the General Party Branch of Fu Shi Cun and director of the village committee, said that until 2019, the first dragon boat race was held in the village, which made the number of tourists in the village exceed 10,000.

　　After that, Fu Shi Cun held a dragon boat race every year, and the village also set up its own dragon boat team, rescue team, training team and cheerleading team, showing a strong atmosphere in which all members participated in the dragon boat race. This year, the village created the theme activity of "Fun Stone Tour Xixi" in the crazy water-splashing season. During the whole summer water-splashing season, special water projects such as kayaking and paddle board were introduced to create a rural water park to attract tourists and promote the village’s collective income.

　　Spend a holiday in Jiaojiang Art Museum

　　Zhejiang Online June 23 rd(Reporter Chen Jiuren Sharing Alliance Jiaojiang Zhao Yang) On the evening of 22nd, the Jiaojiang Art Museum in Wenchuang Garden, Laoliangfang, Taizhou City was brightly lit, and people came to see the exhibition, listen to songs and go shopping in an endless stream. The first wonderful night activity of the art museum in Jiaojiang District is in full swing.

　　In the art gallery, a large art exhibition is on display. On the floor of the exhibition hall on the third floor, two huge 3D realistic paintings attract people to stop and take photos.

　　The lobby on the first floor of the art museum is full of children waiting to draw. Luo Pujian, president of Taizhou Cartoonist Association, and other four painters are painting comic portraits for the public.

　　A lawn concert is being held at the Little Square outside the art museum. Next to it are experience activities such as printmaking, pottery, flower arrangement and paper cutting.

　　"I hope there will be more such literary and artistic activities." Fan Fan, a citizen of Jiaojiang, specially came to see the exhibition with his son. Rich activities, let them have fun.

　　According to reports, Taizhou Laoliangfang Wenchuang Park is a gathering place for creative design shops and a popular gathering place for Jiaojiang Night Economy. This year, Jiaojiang District launched the weekend art museum tour, with the art museum as the core, to create a normalized art activity that integrates teaching, interaction and display, and integrates garden and market.

　　Yiwu foreigners go into battle to make dumplings.

　　Zhejiang Online June 23 rd(Reporter Li Jiao Yan correspondent Fu Bolin) On the morning of the 22nd, the New Era Civilization Practice Institute in beiyuan street, Yiwu was very lively. The Neighborhood Festival "Chinese and foreign families welcome the Asian Games from" righteousness "and" Zongzi "is held here. More than 10 foreign friends from Pakistani, Israeli, Indian and other countries gathered with five groups of China families to appreciate the charm of China’s traditional culture.

　　At the event site, Chinese and foreign friends immersed themselves in traditional folk customs such as dumplings, throwing pots and paper-cutting, and felt the beauty of Chinese culture. All of them had a great time. "This is my first time to participate in folk experience activities with China residents." Mimi, a foreign teacher in Yiwu, talked about her feelings about the Dragon Boat Festival, and thought that the traditional culture of China was very attractive, hoping to have a better understanding. As the highlight of this activity, the experience of making zongzi has become the most popular activity. The green leaves, white glutinous rice and long zongzi lines have stumped many foreign friends. Volunteers and China family members teach foreign friends how to make zongzi.

　　"I hope that through this activity, more people will understand the traditional culture of China and feel the charm." The relevant person in charge of beiyuan street said. It is reported that beiyuan street has become a civilized person by building a "15-minute civilized practice service circle" with global coverage and ready access. Focusing on the theme of "Our Festival", it has concentrated on developing civilized practice in the new era, and is committed to creating a beautiful, harmonious and livable living environment for residents, spreading civilized ideas and carrying forward the new trend of the times.

　　[car home Engine Analysis] Today, with the increasing popularity of electric vehicles, many manufacturers are still insisting on the development of internal combustion engines. After all, in the domestic and even global markets, oil vehicles still have an irreplaceable position in many application scenarios. Speaking of SAIC MAXUS, many consumers may immediately think of their hard-core SUVs, pickup trucks and RV products, and today it is from SAIC MAXUS Xuanyuan Power that we want to talk about.

　　Speaking of diesel engines, in the traditional cognition of many consumers, diesel engines have the advantages of durable leather, high torque, low fuel consumption, etc., and are suitable for use on complex roads, climbing hills, heavy loads, etc., so they are also the first choice for many hard-core off-road vehicles. However, noise, pollution and other problems have also discouraged many consumers. What changes can diesel engines make in the hands of SAIC Chase engineers?

What is SAIC Chase Xuanyuan Power Technology?

　　The brand-new SUV territory of SAIC Chase MAXUS is equipped with the first diesel light hybrid power technology in Asia, which combines a 2.0T SAIC π Bi-Turbo double supercharged diesel engine, a ZF 8AT automatic transmission and a 48V hybrid architecture. The technology is named "SAIC Chase Xuanyuan Power Technology", and this diesel engine has also won the reputation of "Top Ten Engines of China Heart" in 2020.

2.0T SAIC π Bi-Turbo Dual Supercharged Diesel Engine

　　As one of the top ten engines of the year, this 2.0T twin-supercharged engine has its own good skills, and it is also the core of this Xuanyuan power. Let’s take a look at what "black technologies" it has.

　　The vehicle adopts WGT+VGT two-stage turbocharger, which is adjusted by three vacuum valves to realize the free switching between high and low pressure stages, and has three working modes, namely, the low-speed stage uses small blades, the middle-speed stage uses two blades at the same time, and the high-speed stage uses large blades, which improves the engine efficiency. When the engine speed is 1000rpm, the turbine will intervene and reach the maximum torque output at 1500rpm, which will increase the low-speed torque and power of the vehicle by 15% and 30%.

　　The water-air intercooler adopts water cooling and air cooling at the same time. Under the same air-fuel ratio, the engine power will increase by 3%~5% for every 10℃ drop in the temperature of pressurized air.

　　At the same time, this engine also applies the intelligent single-axis continuous variable vortex control valve for the first time. When the engine is in high working condition, the control valve will open a relatively flat intake port, so that air can enter the engine cylinder quickly and smoothly. When the engine is under low load, the control valve will open the air passage with spiral cross section to help the air entering the engine cylinder produce better vortex effect, so that the pressure difference of each cylinder can be less than 3%, and the air intake can be more uniform, thus making the combustion of each cylinder of the engine stable, achieving smoother power output, and reducing the emission of particles and carbon monoxide and fuel consumption.

　　This diesel engine adopts a two-stage variable oil pump, which can adjust the oil pump flow in real time according to different speed loads while meeting the oil pressure demand. Low-pressure mode is adopted at medium-low speed and medium-low load; When there is a high speed and high load demand, the high pressure mode is adopted. Through adjustment, the oil pump can run at the lowest energy consumption, thus reducing fuel consumption. Through the NEDC (New European Cycle Test) cycle test, the fuel consumption of the whole vehicle can be reduced by 2~3%;

　　In addition, this diesel engine is equipped with a double-shaft balancing mechanism and a double-loop EGR system, in which the balancing shaft is asymmetrically arranged to balance the engine covering torque, which greatly reduces the second-order vibration, makes the engine run more smoothly, and also reduces vibration and noise. The dual-loop EGR system can reduce the warm-up time, reduce fuel consumption and improve the heating effect of air conditioning. (EGR is the full name of exhaust gas recirculation system. By re-injecting some exhaust gas into the engine cylinder, the combustible mixture is diluted and the combustion efficiency is reduced, so as to achieve the purpose of controlling the working temperature of the engine, reducing Nox emission and reducing urea consumption. )

　　In addition to the above, this diesel engine also adopts Bosch’s ultra-high pressure fuel injection system, which can obtain more accurate fuel supply control, and crankshaft offset technology, which can effectively reduce the running noise and wear of the engine piston. At the same time, a number of NVH optimizations have been carried out.

48V light mixing system

? The 48V light mixing system of the vehicle adopts Valeo 48 BSG motor, with special bidirectional tensioner, and the gear train speed ratio is as high as three times, which further amplifies the output torque of 48V BSG and effectively improves the low-speed torque characteristics of diesel power. When the 48V battery is charged, the engine is started by BSG, and the vehicle starts more smoothly, the starting time is shortened from the traditional 0.6 seconds to 0.3 seconds, and the starting noise is reduced by 10-15 dB. With the assistance of the motor, the torque of the power system is increased by more than 30%, and the starting acceleration of the vehicle below the medium and small throttle of 30%-50% is increased by more than 33%; 0-100km/h acceleration time is shortened by 0.4 seconds.

　　In addition to performance, fuel economy has been further improved. Under high-speed working conditions, the surplus torque of the engine drives the 48V motor to charge and store energy. The fuel consumption under WLTC can be saved by 8%, while Nox emission can be reduced by more than 50% in RDE test at most.

　　The new Newcastle disease vaccine with gene VII is the first Newcastle disease vaccine with independent intellectual property rights in China, and it is also the first vaccine to effectively prevent and control Newcastle disease in geese, which can simultaneously prevent Newcastle disease in chickens and geese. At the beginning of this year, this achievement won the second prize of the National Technology Invention Award at the 2019 National Science and Technology Awards Conference.

　　Leading this work is Liu Xiufan, an academician of China Academy of Engineering and a professor at Yangzhou University. He believes that human health, animal health and ecological environment health are a whole, and we need to practice the concept of "one health".

　　Half a century of scientific research, "fighting" with animal diseases

　　Liu Xiufan, who is 79 years old this year, still shows amazing scientific research creativity. He graduated from Subei Agricultural College in 1965, majoring in veterinary medicine, and has been "fighting" with animal diseases for more than half a century.

　　One winter day in 1965, three cows "Baobei" of a production team in gaoyou county, Jiangsu Province suffered from organophosphorus pesticide poisoning, which made them seriously ill. After the diagnosis, Liu Xiufan, who just graduated and stayed in school, quickly removed the pesticides from the cattle and gave an antidote. A few days later, the poisoned cow recovered. "This is my first home visit after graduation. Simple farmers will not express their gratitude with too many words, but just hold my hand tightly and refuse to let go." Liu Xiufan said.

　　In 1980, Liu Xiufan was selected by the Ministry of Education to go to the United States for further study, and successively studied veterinary biotechnology at Michigan State University and the Poultry Research Institute of the US Department of Agriculture. "When I first arrived in the United States, the director of the International Exchange Center, who helped me with the formalities, saw my resume and said that you studied veterinary medicine, so he called me Doctor and called other visiting scholars Mister." It was only this little bit unusual that made Liu Xiufan feel very happy at that time: "In foreign countries, veterinary medicine is a very respected profession, and it is great to study veterinary medicine."

　　In addition to taking courses related to veterinary medicine, Liu Xiufan also specializes in the study of monoclonal antibodies against Marek’s disease in chickens. "In the end, I successfully developed a monoclonal antibody against Marek’s disease in chickens, which became the standard reagent for international serotyping." Liu Xiufan said that in less than three years after returning to China, he took the lead in applying monoclonal antibody technology to the research and control of animal diseases. "More than 100 kinds of monoclonal antibodies with different epitopes of seven pathogens such as Marek’s disease virus, Newcastle disease virus, Escherichia coli, Salmonella and avian influenza virus have been developed. The study of monoclonal antibodies not only fills the gap in China, but also reaches the advanced level of similar research in the world. "

　　"Newcastle disease, commonly known as chicken plague, is one of the two most serious infectious diseases that endanger the global poultry industry, just like highly pathogenic avian influenza." Liu Xiufan said that the incidence and mortality of Newcastle disease is as high as 100%, and it has been listed as a legally reported animal disease by the World Organization for Animal Health.

　　Liu Xiufan said that vaccine immunization is an important method to prevent and control Newcastle disease. The infection rate of Newcastle disease virus in chickens in China is high, and all chickens are vaccinated at high frequency. The most widely used is the gene II LaSota vaccine introduced from abroad. "However, since the 1990s, the epidemic characteristics of Newcastle disease in China have changed greatly, and atypical Newcastle disease is still common in chickens vaccinated with LaSota vaccine at high frequency."

　　Grinding a sword in eighteen years to create the first Newcastle disease vaccine in China

　　In the late 1990s, Liu Xiufan’s team launched an epidemiological survey to conduct molecular epidemiological research on Newcastle disease virus in China.

　　"By analyzing the genotypes of more than 1,500 Newcastle disease virus isolates, we first discovered the genome length characteristics of Newcastle disease virus type VII, which proved that more than 95% of the virulent Newcastle disease viruses prevalent in chickens and geese are genotype VII, which has no host specificity and can be cross-infected." Liu Xiufan said.

　　Why does gene ⅶ Newcastle disease virus cause a serious epidemic? Liu Xiufan’s team further revealed the pathogenic mechanism of gene VII Newcastle disease virus. "Gene VII Newcastle disease virus will cause serious damage to the immune organs of chickens and geese, leading to their immunosuppression. The commonly used LaSota vaccine does not match the genotype and antigenicity of gene VII Newcastle disease virus, and its ability to clear the virus is weak, resulting in the frequent occurrence of atypical Newcastle disease in chickens and the outbreak of goose Newcastle disease. " After finding out the culprit, developing a new vaccine as soon as possible has become a top priority for Liu Xiufan.

　　Since 2001, from more than 200 epidemic strains of Newcastle disease virus type VII, the team has screened and obtained a strain with high reproductive titer, strong immunogenicity and good cross-protection in chicken embryos as a donor, constructed an infectious clone containing the full-length genome of the strain, and pioneered the reverse genetic technology platform for directly weakening the virulent Newcastle disease virus type VII in the world, breaking through the technical bottleneck that conventional means cannot weaken the virulent Newcastle disease virus type VII.

　　In 2006, Liu Xiufan’s team successfully invented gene VII Newcastle disease vaccine strain A-NDV-VII, which is the first gene VII vaccine strain in the world and the first Newcastle disease vaccine strain with independent intellectual property rights in China. Compared with the performance parameters of the international common vaccine strain LaSota, the vaccine strain has weaker virulence and better immunogenicity, the titer of antibody produced after immunization is more than 4 times, and the virus removal ability is more than 10 times. It can be used not only for chickens but also for geese. "When the vaccine strain is created, we have the’ seed’ to develop the vaccine." Liu Xiufan said with a smile.

　　Using the invented attenuated strain A-NDV-VII as seed virus, the team developed the first registered inactivated vaccine of Newcastle disease virus type VII in the world, which solved the major problem of Newcastle disease prevention and control in chickens and geese in China. In 2014, the vaccine obtained the national first-class new veterinary drug certificate. Since its introduction, the vaccine has produced and sold a total of 7.51 billion feathers, which has been popularized and applied in 31 provinces, municipalities and autonomous regions across the country, increasing the efficiency of aquaculture enterprises by more than 5 billion yuan and achieving remarkable economic, social and ecological benefits. "We should treat the health of the ecological environment as a whole." Liu Xiufan said.

　　Human beings have gained experience in the struggle against previous plagues.

　　The history of mankind is also a history of fighting the plague. Liu Xiufan said that in history, smallpox, plague, flu and other plagues have claimed hundreds of millions of lives and caused painful disasters to mankind. In the struggle against previous plagues, mankind has gained valuable experience and defeated the epidemic. In recent years, the emerging Nipah virus, SARS virus, MERS virus and highly pathogenic avian influenza virus have attracted great attention and attention. "We may face new viruses in the future."

　　"When dealing with a new virus, we must first take quick emergency measures to control and eliminate the source of infection, cut off the route of virus transmission, protect susceptible groups, and prevent the spread of the virus from expanding." Liu Xiufan said that at the same time, it is necessary to systematically carry out epidemiological research, pathogenic mechanism and immune mechanism research, and carry out joint research to develop new diagnostic methods and effective prevention and control products.

　　Liu Xiufan said that the H7N9 subtype avian influenza virus that appeared after 2013 infected people. The virus was the product of multiple subtype avian influenza viruses, and its internal genes were all derived from H9N2 subtype avian influenza virus. "Although the probability of infection with avian influenza virus in the exposed population is very low, we must strengthen the monitoring of avian influenza virus to prevent the virus from mutating and spreading from person to person, triggering a new influenza epidemic. Therefore, the control of avian influenza is not only economically important, but also plays an important role in public health. "

　　Meeting point reporter Wang Tuo correspondent Lu.

Original Bund Jun Bund TheBund

Saudi Arabia is building a

Super exaggerated linear city

Such a sci-fi picture

I’ve only seen it in movies

It is my pyramid and will go down in history forever.

What makes Saudi Crown Prince Mohammed bin Salman sigh so much is an exaggerated building-perhaps it is more appropriate to call it "the city" directly.

Just last week, Saudi Arabia officially announced an architectural plan called "The Line", which exploded in the global architectural circle.

This straight "line" is located in the northwest of Saudi Arabia, starting from the Red Sea, with a length of 170 kilometers, a width of 200 meters and a height of 500 meters, covering a total area of 34 square kilometers.

To put it simply, two super-long glass skyscrapers are parallel, and an entire city is sandwiched between them.

It will also become an important part of Neom, a new city in northwest Saudi Arabia.

Such a crazy architectural idea, which we only saw in science fiction movies before, is now going to become a reality?

But don’t be too happy, even in Saudi Arabia, which is "rich to the brim", it is not easy to build such a behemoth.

In recent years, Saudi Arabia has competed with Dubai, United Arab Emirates, and wants to seize the name of "the most luxurious in the world" by countless grand and futuristic wonders.

These renderings are really beautiful, but what is the probability of completion?

01

A super-long linear city

The Line project is designed by American firm Morphosis, and the budget will reach an astonishing $1 trillion, which will be completed in 2030.

Such a huge volume, if calculated by a single building, will undoubtedly become the largest building in the world after completion.

Ben Salman said that The Line provides a brand-new concept of urban planning and design.

"The vertical hierarchical distribution of urban functions allows people to travel seamlessly in three-dimensional space, which we call’ zero gravity urbanism’."

Different from the layout of traditional cities radiating from the city center, The Line City, as its name implies, brings all functions together in this straight line.

Two super-long skyscrapers with a height of 500 meters enclose the outline of the city. By then, they will surpass our world financial center (492 meters) and become the 12th tallest building in the world.

The building extends all the way from the red sea to the mountains, 800 meters from the mountains, and then continues to extend to the desert. Because the surface of the building is covered with glass curtain wall, it is also called "Mirror Line", which is full of science fiction.

The 200-meter-wide area between the two buildings is the public area of the city.

These functional facilities are all three-dimensional-vertical farm layered farming, connecting canteens and kitchens, making urban residents’ food baskets self-sufficient; The stadium is located at a height of 305 meters, and residents run, play ball and have fun in the sky.

02

NEOM, the new future city of Saudi Arabia

Another major feature of The Line is environmental protection. It is completely powered by renewable energy. 95% of the land is divided into nature reserves, where sunlight, plants and natural ventilation are balanced.

There are no roads and private cars in this city, and countless sidewalks and bridges connect two buildings.

People can walk to the public station they want to go to in 5 minutes at most, then take the high-speed train to their destination and reach the other side of the city in 20 minutes.

When completed in 2030, The Line will welcome the first batch of 1.5 million residents. In the later stage, we will gradually expand and improve the functions, and increase facilities such as houses, shopping malls, parks and schools, which can accommodate up to 9 million residents.

For Saudi Arabia, this is actually very important, because it is also one of their original intentions to build a new future city NEOM in the northwest, and The Line is an important part of this new future city.

NEOM covers an area of 26,500 square kilometers. In Ben Salman’s vision, it will become a place where everyone in the world can leave their footprints with creativity.

"The world is facing an environmental crisis, and NEOM can provide the most imaginative solutions. We have a team of the brightest talents in engineering and architecture to realize these cutting-edge ideas."

Environmental protection is a signboard with great communication value, but it is not the whole of NEOM. With a huge investment of trillions of dollars, the crown prince is not thinking of doing "charity" for environmental protection.

As early as 2016, Saudi Arabia issued the so-called "Vision 2030", with the goal of diversifying the Saudi economy and getting rid of its dependence on oil.

NEOM, the new future city, is a trump card of Vision 2030.

The Line alone can provide 380,000 new jobs, and it is expected to provide Saudi Arabia with a gross national product of 47.9 billion US dollars by 2030.

03

What is the probability that the spectacle will end badly?

In the "Vision 2030", the big goal is ahead, and now Saudi Arabia is building a lot of buildings, and exaggerated projects are one after another.

Besides NEOM, another most famous project in Saudi Arabia is the Red Sea Project, which will be an important step for Saudi Arabia to become a "global luxury tourist country".

500 kilometers north of Jeddah, Saudi Arabia, a super-large luxury resort will be built, and 22 brand-new islands will be built on the Red Sea.

The participating big-name design firms include Kengo Kuma, Foster+Partners and Killa Design, and they will build a large number of seascape villas and desert tents on these islands.

In addition, they have signed contracts with 12 luxury hotels including Ritz-Carlton Seclusion, Magnificent, Liushan, St. Regis, Raffles and Addison. Magnificent and Ritz-Carlton Seclusion are scheduled to be completed and opened by the end of next year.

Building luxury hotels and wonders everywhere, wrestling with rivals such as the United Arab Emirates, and now the $1 trillion The Line is launched …

Is Saudi Arabia really so rich?

Of course, Ben Salman has his own small abacus, attracting investment all over the world with renderings, and plans to list NEOM in the new future city in 2024 to attract more investors.

But the problem is that the Saudi Crown Prince has a bad reputation in the West.

In particular, in 2018, his approval of the execution of Saudi journalist Kachouqi was exposed, which was widely resisted by the international community, and foreign investors in Saudi Arabia even withdrew their funds.

As a result, many magnificent buildings in the original plan were forced to stop the progress of the project, and even have been unfinished.

One of the most famous examples is the "Jeddah Tower" in Jeddah, which started construction in 2016 and has a design height of 1,008 meters. It is planned to surpass the Burj Dubai as the tallest building in the world.

Unexpectedly, in January 2018, construction workers suffered a collective strike of unpaid wages, reaching a height of 600 meters and stopping.

Originally expected to be completed last year, there is only a semi-finished product until now.

Today’s The Line is actually not optimistic about the outside world after the design scheme is announced, and some people even predict that it will be "a bad end".

On the one hand, the reason for funds is that the construction and implementation are too difficult.

For example, it is necessary to drill through the mountains and dig a huge tunnel with a length of 800 meters and 30 floors to let the skyscrapers pass.

In addition, high-rise buildings will be built on the ground in the desert where there is nothing, and 10 huge mansions will be built …

By 2030, can this imaginative "line" really end successfully?

In the bizarre entertainment circle, the star’s every move often leads to heated discussion. Recently, Huang Lei’s image seems to be facing collapse, and the comment area has fallen. Once upon a time, he was the "Yellow Chef" with warm sunshine, and brought the audience wonderful memories of home cooking in "A Life I yearn for". However, with the rise of "Archaeological Tide", all the past things were rediscovered, and the people in Huang Lei became confusing. He has suddenly become the target of public criticism from a highly appreciated "housework male god", which has aroused deep thinking and discussion among netizens.

When it comes to Huang Lei, people may think of his excellent cooking skills and the warm atmosphere created in the program for the first time. He once served as a "God Chef" in the multi-season "Life of Desire", and these beautiful pictures have long been deeply rooted in the hearts of the audience. However, with the wave of "black history" being dug up, the glorious moment of the past was broken, and the image of Huang Lei began to be doubted.

In particular, the "stewed bean incident" has become the focus of hot discussion among netizens. When Song Dandan visited the mushroom house, the stewed beans prepared for her by Huang Lei caused a joke of food poisoning. Although the program group did not explicitly say that the responsibility lay with him, netizens did not buy it, and they used the social platform "archaeology" to question his cooking level. This incident has made many people begin to reflect: Does this former "housework male god" really have excellent cooking skills? Or just rely on the aura set by people?

In addition to stewed beans, the pot-stewed pork made by Huang Lei in the program also attracted a lot of controversy. Netizens joked that its content really didn’t match the name and doubted the degree of care in the production process. Put a bunch of hawthorn, there is no shadow of meat at all, is it a poorly designed pot-wrapped meat? Many people ridiculed: "Is this pot-wrapped meat originally intended to be made into pot-wrapped hawthorn?" These ridicules seem to have aggravated netizens’ doubts about his cooking.

And Huang Lei’s attitude in the program is also embarrassing. He often makes fun of Shen Teng, and his attitude seems to be complacent, and he doesn’t seem to care about the evaluation of the outside world. This randomness revealed the estrangement between him and the audience to some extent, and even attracted Shen Teng’s aggressive response, which made people question his attitude towards life. Someone bluntly said, did Huang Lei secretly set a trap at the scene and let Shen Teng take the blame for his dishes? This disturbing little detail makes people wonder whether the former "God Chef" is slowly losing its true self.

In addition, He Jiong, who is in obvious contrast with Huang Lei, praised Huang Lei’s cooking blindly in the program, but it seemed hypocritical. Such praise, it seems, not only failed to enhance Huang Lei’s image, but gave people a feeling of being late. The gap between overly optimistic evaluation and real word of mouth makes the audience’s trust in Huang Lei gradually weaken.

Huang Lei’s example can’t help but make people think, the peak of a star is often very short. Over-reliance on people’s design without perfecting one’s inner self may eventually end in collapse. Just like Huang Lei, blindly catering to the expectations of the outside world may not be able to win long-term popularity and love. With the questioning of people’s design, many viewers began to re-examine the reality and illusion of entertainment circle. The expected perfect people’s design is actually an illusion. They also realize that stars are ordinary people, and it is inevitable that they will make mistakes. Everyone should be more tolerant of them.

As this incident shows, Huang Lei’s story is not only his case, but also a mirror of the whole entertainment circle. Perhaps, after experiencing doubts and confusions, the stars can better understand that if they want to gain a firm foothold in this industry, they must have real talents and practical knowledge, rather than relying on a makeshift person.

Finally, the collapse of Huang Lei’s man-made device triggered a wide discussion among netizens, but we also expect him to stand up again after the storm and bring more surprises to the audience. In this highly competitive entertainment circle, it may not be possible to gain a foothold for a long time only by abusing people’s equipment, and the transparency and truth in facing the audience will be truly recognized. In short, stars need to face up to their own shortcomings and actively show their true side, so as to be more stable in the future.

In daily work and life, using technology and AI to help themselves may also be a direction for Huang Lei people to reshape their personal design.

The terrorist attacks in Russia shocked the world and made Russian anti-terrorism forces the focus of discussion.

According to CCTV news reported on March 26, local time, on March 26, the Russian Federal Security Service announced that it had foiled a terrorist attack that was planned to be carried out in a humanitarian relief material receiving station in Samara. Bortnikov, director of the Russian Federal Security Service, said that Russia still faces a terrorist threat.

On the evening of March 22, local time, a terrorist attack took place in the "Saffron City Hall" in Moscow, Russia. According to the statistics of the Russian investigation Committee, the attack has caused 143 deaths and 182 injuries, and the concert hall building was burned in the fire. This is the most serious terrorist attack in Russia in the past two decades. Soon after, Russian military and police personnel, including Chechen special forces, quickly took action and completed the interception and arrest when the murderer was about 100 kilometers away from the Ukrainian border in Bryansk State.

In order to deal with terrorism, Russia has set up several special operations forces that are very professional and have strong combat effectiveness, and carried out work according to the characteristics of anti-terrorism operations.

The professional anti-terrorism force born of terrorist attacks

Russia has long been threatened by terrorism. In the mid-1990s, terrorist activities in Russia became increasingly rampant and showed an upward trend. In the early 21st century, it reached an unprecedented scale, and terrorist attacks with global significance such as Beslan hostage incident occurred at this stage. Terrorists from Chechnya, Central Asia and Afghanistan entered Russia to spread terrorism, extremism and separatism, recruit members and plan terrorist activities.

In order to deal with the threat of terrorism, Russia has been paying more attention to the construction of anti-terrorism mechanism, and at the same time, it has intensified its efforts to crack down on terrorist activities. At present, it has formed a relatively solid foundation of anti-terrorism laws and regulations, and established a vertical command and coordination system for anti-terrorism operations. At the same time, Russia also attaches great importance to the implementation of anti-terrorism operations, and has established several special combat forces with very professional and strong combat effectiveness to carry out work according to the characteristics of anti-terrorism operations.

At present, Russia’s special anti-terrorism forces mainly include the General Directorate of the General Staff of the Russian Armed Forces, the Alpha and the Signal Flag, and the Russian Federal Internal Security Forces, among which the Alpha and the Signal Flag belong to the Federal Security Administration and the Internal Security Forces belong to the Ministry of Internal Affairs.

Among them, the General Staff of the Russian Armed Forces, also known as Gruu, claims to be the most confidential department of Russian intelligence agencies. On October 21, 1918, at Trotsky’s suggestion, Lenin signed an order to formally set up the registration department under the Field General Staff of the Revolutionary Military Commission of the Republic to lead the military intelligence work on all fronts of the Red Army in a unified way, with Simon Ivanovich Aranov, who was born in Cheka, as the first minister. The story of "Gruwu" begins, and November 5 every year is designated as the anniversary of the establishment of "Gruwu". Unlike the KGB (the KGB was split into two parts after the disintegration of the Soviet Union: the Federal Security Service and the Foreign Intelligence Service), Gruwu did not sink after the disintegration of the Soviet Union and still played an important role in the armed forces of the Russian Federation. On November 5, 2006, on the 88th anniversary of the founding of Grupo, the new headquarters of Grupo in Moscow was officially opened.

The specific establishment and tasks of the special operations forces under the "Gruu" remain a mystery until today. It is reported that there are currently 24 well-trained special assault brigades in Gruu, with a total number of about 30,000 people. Its main task is to deter and prevent sudden attacks and strike behind enemy lines. Its main base is located in Chuchikovo, Ryazan, Russia. From the two wars in Chechnya to the little green men in Crimea, to the armed conflict in eastern Ukraine and the civil war in Syria, there are "Gruu" special forces. It is generally believed that on April 21, 1996, it was the "Gruu" special forces that provided accurate strike guidance on the spot, which enabled two Russian Su -25 fighters to launch missiles and successfully killed Chechen rebel leader dudayev, who was making a mobile phone call to the outside world.

In recent ten years, the actions against other Chechen rebel leaders, such as basaev, maskhadov and others, are basically recognized by the outside world as being related to "Gruwu". At the end of 2015, five Russian special forces were killed in combat operations in Syria. Although Russian officials once denied it, it is generally believed that these people are soldiers of Gruu. In the centennial celebration speech in 2018, Putin fully affirmed the role played by Gruu in Syria in the past few years, pointing out that Gruu provided vital target information and other intelligence for the Russian army to crack down on extremist organizations in Syria.

Both "Alpha" and "Signal Flag" special forces belong to the Federal Security Administration. The two armies have made great achievements in the hostage incident in the theater of Moscow Bearing Factory and the hostage incident in Beslan, which has attracted the attention of Russia and abroad.

The purpose of "Alpha" special forces is mainly to engage in anti-terrorism activities in Russia and deal with terrorism such as hostage-taking and bomb-planting. Its history can be traced back to 1974. It was originally called "KGB Group A" and was renamed "Alpha" in 1991. "Alpha" special forces are carefully selected from national security organs, airborne troops, border guards and military school graduates. In addition to being physically strong and responsive, they also need to pass intelligence tests.

The unit has now become the backbone of Russia’s counter-terrorism. In 1993, the terrorist Zaharijev hijacked a Russian civil aviation Il -86 passenger plane. Alpha was ordered to go out, sneaked into the cabin from the cargo hold at night, and quickly subdued the gangsters. Zaharijev was captured on the spot, and the plane and passengers were all safe. In a hijacking incident in 1997, "Alpha" once again captured the gangster alive, and all 142 passengers were safe and sound.

Among the anti-terrorism forces, the "Alpha" and "Signal Flag" special forces are two well-known forces, both of which belong to the Federal Security Administration.

The main task of the "signal flag" special forces is to carry out the security work of Russian institutions abroad, including anti-sabotage, anti-espionage, anti-subversion and defending the leaders. The "signal flag" special forces was established in 1981, initially under the KGB Anti-Spy Bureau, and then disbanded and reorganized in 1993. It is reported that the "signal flag" special forces usually carry out activities in classes, and the number of people in each class ranges from 10 to 30. When the situation is urgent, several classes can be quickly combined to form a larger force.

According to the data, during the war in Afghanistan, the "signal flag" has been active, and every province in Afghanistan has its action team. In addition, "Signal Flag" has conducted similar activities in Cuba, Syria, Vietnam, Mozambique, Angola and Nicaragua. In 1992, 10 members of the "signal flag" subdued 14 armed thugs in 10 seconds at the "three stations" subway station in Moscow, and seized $1 million in counterfeit US dollars. In 1993, the "signal flag" special forces successfully stopped a premeditated terrorist explosion outside Yekaterinburg. On July 16, 2023, five Russian "signal flag" special forces went deep behind enemy lines and carried out sabotage operations on an underground ammunition depot in Odessa.

The special forces of the internal affairs forces of the Russian Federation are under the jurisdiction of the Russian Ministry of Internal Affairs, mainly including the 604 Special Operations Center, Rosic and other special forces. Among them, the 604 Special Operations Center was formed by the merger of the "Warrior" special forces and the "Ross" special forces. It is the core of the special forces of the Ministry of Internal Affairs and is responsible for counter-terrorism and other tasks such as responding to domestic riots and prison riots. The special forces of the Ministry of Internal Affairs have also made great achievements in many anti-terrorist operations, including the hostage incident in the Grand Theatre of Moscow Bearing Factory, and they also belong to one of the backbone of Russian anti-terrorist operations.

After the outbreak of the Russian-Ukrainian conflict, Russian anti-terrorism forces also participated, which affected the domestic anti-terrorism capability to some extent. Although Russia discloses little information, it is generally believed that the fierce conflict between Russia and Ukraine has contained Russia’s anti-terrorism forces. According to media reports, on July 16, 2023, five Russian "signal flag" special forces went deep behind enemy lines and carried out sabotage operations on an underground ammunition depot in Odessa. It was reported that the Russian army had attacked the facility with cruise missiles before, but it was unsuccessful. In order to completely destroy the underground ammunition depot, the Russian army sent a sabotage team behind the enemy lines composed of five special warfare players to secretly approach the target and launch a surprise attack. After killing several defenders, the Russian army installed a timed explosive device to blow up the ammunition depot, and then all the staff returned to the station safely.

A rising star of Chechen special forces

In addition to the above troops, the Chechen special forces involved in the arrest of the suspects of the "concert hall terrorist attack" are also a rising star in the Russian anti-terrorism field.

After the Chechen war ended in 2001, local terrorist activities were very active. In order to effectively crack down on terrorist activities carried out by illegal organizations, while sending a large number of federal troops, the Russian central government also agreed to set up local armed forces subordinate to local leaders.

In order to stabilize the domestic situation, Chechen leader Kadyrov recruited 7,000-14,000 separatist militants in 2002 -2005, and incorporated some of them into the security department of the Republic. Only the independent patrol team of the Chechen Ministry of Internal Affairs has 10 companies (about 4,000 people). In order to effectively carry out anti-terrorism operations, Kadyrov established the Northern Battalion and the Southern Battalion in 2006. The Russian Ministry of Internal Affairs gave them the official designations of Independent Special Battalion 248 and 249, and the Russian Ministry of Internal Affairs also allocated 2 billion rubles for them. After the establishment of the two battalions, they were controlled by the 46th Mobu Brigade stationed in Chechnya by the Russian Ministry of Internal Affairs. Each battalion consists of three patrol companies, one reconnaissance company and one support unit, and the support unit consists of medical platoon, communication platoon and technical support platoon. The total number of the two battalions is more than 1,200, including more than 700 in the northern battalion, which is stationed in Grozny, the capital of the Chechen Republic, mainly to protect the security of the capital, and more than 500 in the southern battalion, which is stationed in Vijno area, which is adjacent to the Republic of Dagestan. The local terrorist activities are very active and cracked down.

At present, the "Ahmat" rapid reaction special force is a well-known Chechen unit, which belongs to the National Guard of the Russian Federation and is deployed in Chechnya. It was named "Ahmat" to commemorate the first Chechen President akhmad kadyrov. This special force was established in 2009, and its commander is the Deputy Minister of Internal Affairs of the Chechen Republic, Apti Arnold. After the Russian-Ukrainian military conflict broke out in February 2022, the "Ahmat" special forces participated in the war against Ukraine and achieved some results.

During the "Thirteenth Five-Year Plan" period, under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, the main objectives and tasks of the "Thirteenth Five-Year Plan" were successfully completed, and the great rejuvenation of the Chinese nation took a big step forward. Premier Li Keqiang pointed out in his government work report in 2021 that during the 13th Five-Year Plan period, China’s economic and social development made new historic achievements. Ten sets of tax data fully reflect this point.  

In the past five years, the total tax reduction and fee reduction has exceeded 7.6 trillion yuan   The macro tax burden is decreasing year by year.

The General Secretary of the Supreme Leader pointed out that tax reduction and fee reduction policies and measures should take root and let enterprises go into battle lightly. This year’s government work report showed the transcripts of tax reduction and fee reduction in 2020, which reduced the burden on market players by more than 2.6 trillion yuan, including 1.7 trillion yuan in social security fees. Statistics from the State Administration of Taxation show that during the "Thirteenth Five-Year Plan" period, the scale of new tax reduction and fee reduction in five years totaled more than 7.6 trillion yuan.

During the "Thirteenth Five-Year Plan" period, the CPC Central Committee and the State Council accurately implemented counter-cyclical economic adjustment and introduced a series of tax reduction and fee reduction policies in an orderly manner. In 2016-2018, we will comprehensively push forward the pilot reform of the camp, degenerate and reduce the value-added tax rate, and raise the standard of individual tax deduction. In 2019, a larger scale of tax reduction and fee reduction will be implemented. In 2020, seven batches of 28 preferential tax and fee policies will be introduced to support epidemic prevention and control and economic and social development. With the implementation of a series of tax reduction and fee reduction policies by the CPC Central Committee and the State Council, China’s macro tax burden (that is, the proportion of tax revenue to GDP in general public budget revenue) was 17.47%, 17.35%, 17.01% and 16.02% respectively from 2016 to 2019, and further decreased to 15.2% in 2020, compared with 18% in 2015 at the end of the Twelfth Five-Year Plan.

Support for innovation and tax reduction totaled over 2.5 trillion yuan   Cultivate and expand new kinetic energy

General Secretary of the Supreme Leader pointed out that independent innovation is an urgent requirement and an important support to promote high-quality development and kinetic energy conversion. We must create conditions and atmosphere, mobilize the enthusiasm of innovation in all aspects, and make every innovation fully generate. In this year’s government work report, Premier Li Keqiang pointed out that during the 13th Five-Year Plan period, China achieved fruitful results in building an innovative country. In recent years, the tax policies supporting scientific and technological innovation have been continuously optimized and improved, and the intensity of tax incentives for innovation has been continuously increased, which has effectively promoted enterprises to increase investment in R&D and guided innovative resources to gather in enterprises, which has played an important role in promoting the implementation of innovation-driven development strategy and the construction of an innovative country.

According to the tax data, during the 13th Five-Year Plan period, the tax reduction and exemption amount of China’s tax policy to encourage scientific and technological innovation increased by 28.5% annually, and the accumulated tax reduction in five years was 2.54 trillion yuan. Tax incentives are more beneficial to manufacturing and high-tech service industries. Manufacturing, information transmission and information technology service industries, scientific research and technical service industries enjoy tax reductions totaling nearly 90%.

From the breakdown data, the number of enterprises enjoying the R&D expenses plus deduction policy in China has increased from 53,000 in 2015 to 339,000 in 2019, an increase of 5.4 times in five years; The tax reduction and exemption increased from 72.6 billion yuan to 355.2 billion yuan, and reached 360 billion yuan in 2020, with an average annual increase of 37.8%. The deduction of R&D expenses continued to increase, which effectively stimulated the R&D investment and innovation vitality of enterprises. The national R&D investment increased from 1.42 trillion yuan in 2015 to 2.44 trillion yuan in 2020, achieving double-digit annual growth and becoming the second largest R&D investment country in the world.

During the "Thirteenth Five-Year Plan" period, the support of various policies, including tax incentives, continued to increase, which effectively promoted the vigorous development of the new economy and new kinetic energy and accelerated the construction of a modern industrial system. According to the tax data, the industries related to the digital economy are growing rapidly. From 2016 to 2020, the tax revenue will grow at an average annual rate of 7.2%, which is 3 percentage points faster than the national overall level. According to the data of VAT invoices, during the Thirteenth Five-Year Plan period, the sales revenue of leading enterprises in the "four basics" industries such as core basic parts, advanced basic processes, key basic materials and industrial technology foundations increased from 1.09 trillion yuan in 2017 to 1.47 trillion yuan in 2020, with an average annual growth rate of 10.8%. The sales revenue of China’s high-tech industry increased by 21.3% annually, which was 5.1 percentage points higher than the national average, among which the sales revenue of high-tech service industry increased by 28% annually, which was 11.8 percentage points higher than the national average.

The green tax system is constantly improving   The comprehensive energy consumption intensity of key tax source enterprises decreased by 6.6%.

General Secretary of the Supreme Leader pointed out that it is necessary to firmly establish the concept of Lucid waters and lush mountains are invaluable assets, promote green development, and fight for the defense of blue sky, clear water and pure land. This year’s government work report summarizes the achievements of China’s green development during the "Thirteenth Five-Year Plan" period, pointing out that China’s pollution prevention and control efforts have increased, the efficiency of resource and energy utilization has improved significantly, and the ecological environment has improved significantly. In the process of promoting green development, the green tax system plays an important role. Since the "Thirteenth Five-Year Plan", focusing on the implementation of new development concepts, China has accelerated the reform of resource tax and environmental protection tax, promoted the rational development and utilization of resources and the clean and energy-saving production of enterprises, and successively issued a series of preferential policies, such as tax relief to support emission reduction and tax credit for equipment investment, to guide enterprises to increase green investment and take the initiative in green transformation, to accelerate the development of green industries and to help build a beautiful China.

In July 2016, the reform of resource tax ad valorem was pushed forward in an all-round way, and a direct linkage mechanism between tax revenue and resource price was established, which better played the role of tax adjustment and promoted the rational development and sustainable utilization of resources. During the Thirteenth Five-Year Plan period, the resource tax revenue totaled 750.9 billion yuan, an increase of 62.3% over the Twelfth Five-Year Plan period, including 175.5 billion yuan in 2020, an increase of 72 billion yuan over 2015, with an average annual growth rate of 11.1%. In particular, the reform of water resource tax has optimized the water use structure and effectively curbed groundwater overexploitation. In 2020, the proportion of groundwater consumption in 10 pilot provinces such as Beijing and Hebei was 33.5%, which was 8 percentage points lower than that in 2016 before the reform. In the pilot provinces, the taxable groundwater intake in the over-exploited area in 2020 decreased by 19.3% compared with that in 2016; Since the reform, more than 8,000 taxpayers in the pilot provinces have stopped pumping groundwater and switched to surface water or tap water, shutting down more than 14,000 self-prepared wells.

The newly levied environmental protection tax has established a tax adjustment mechanism of "more emissions and more levies, less emissions and less levies, no emissions and no levies", and given tax relief incentives for low-standard emissions and centralized management, which effectively promoted the improvement of the ecological environment and green development. From 2018 to 2020, the environmental protection tax has accumulated to 63.15 billion yuan. In 2020, the emissions of sulfur dioxide and nitrogen oxides, the main air pollutants of taxpayers paying environmental protection taxes, decreased by 42.5% and 28.7% respectively compared with 2017 before the reform; The chemical oxygen demand and ammonia nitrogen emissions of major water pollutants decreased by 54.5% and 35% respectively compared with 2017 before the reform.

According to the tax data, during the 13th Five-Year Plan period, the amount of corporate income tax reduction by implementing investment credit policies including environmental protection equipment nationwide increased from 2.33 billion yuan in 2015 to 3.35 billion yuan in 2019, and it is expected to reach 3.5 billion yuan in 2020, with an average annual growth rate of 8.5%. This policy effectively guides enterprises to increase investment in technological transformation and environmental protection equipment. Since 2017, the invoice amount of environmental protection equipment purchased by enterprises nationwide has increased by 14.6% annually. The amount of preferential tax reduction for supporting emission reduction will increase by 7.2% in 2019 and 6% in 2020. Correspondingly, the comprehensive energy consumption intensity (per standard coal/operating income) of key tax source enterprises nationwide will decrease by 6.6% year-on-year. The increase and decrease reflect the positive incentive effect of tax reduction and exemption policies that guide environmental protection, and effectively play the positive role of tax leverage in controlling pollutant discharge.

The tax incentives for helping the poor increase by over 30% annually & ENSP; Helping to win the battle against poverty has achieved remarkable results.

General Secretary of the Supreme Leader solemnly declared at the national summary and commendation meeting on poverty alleviation that China has won a comprehensive victory in the fight against poverty. During the "Thirteenth Five-Year Plan" period, the tax authorities focused on the key areas and key links of poverty alleviation, such as ex situ poverty alleviation and relocation, employment of poor people, and poverty alleviation donations, and continuously increased tax policy support, fully released the tax reduction and fee reduction bonus, and supported the poverty alleviation. The amount of tax preferential policy relief increased from 26.3 billion yuan in 2015 to 74.2 billion yuan in 2019 and reached 102.2 billion yuan in 2020, with an average annual increase of 30.6%, making a positive contribution to resolutely winning the fight against poverty.

Foreign trade is an important part of China’s open economy and an important driving force for national economic development. In order to further expand opening to the outside world and stabilize the basic foreign trade, during the "Thirteenth Five-Year Plan" period, China repeatedly raised the export tax rebate rate to help enterprises cope with the impact of Sino-US trade friction and the negative impact of the global epidemic.
