The empire of Guo Taiming, chairman of Hon Hai Group (2317.TW, known as "Foxconn" in mainland China), is experiencing the torment of "bribery door".

When the successive incidents of jumping off buildings made Hon Hai Group a public focus, new troubles "patronized" Hon Hai. Recently, the news that Hon Hai Group broke the news that high-level officials were suspected of asking for bribes from suppliers was disclosed by the media. Regarding the media reports, Hon Hai Group claimed that most of them were not true, and promised to disclose them within one month.

However, according to the China Business News reporter’s exclusive knowledge from authoritative sources, the mainland police accidentally seized the criminal fact of Deng Zhixian, director-general and manager of SMT(Surface Mount Technology) Technical Committee of Hon Hai Group during the handling of the case, which also triggered a wave of anti-corruption in Hon Hai Group.

Why did this "bribery door" trigger? Why are there loopholes in Hon Hai’s seamless procurement management system? After nearly a month of continuous investigation, our reporter tried to peel away the layers of fog.

The suspect "shakes" out of the "bribery door"

In 2012, Deng Zhixian’s SMT involved a purchase amount of up to 10 billion yuan, and Deng Zhixian, who has been in charge of SMT for many years, has therefore become an important part of the "supply" of various suppliers.

"Deng Zhixian’s fall is very accidental." On January 24, 2013, the reporter learned exclusively from an authoritative insider: "He was reported by a person involved in other cases and was controlled by the mainland police."

Deng Zhixian, who is in his fifties, is the director-general and manager of SMT(Surface Mount Technology) Technical Committee in Hon Hai Group. According to the reporter’s understanding, in addition to Deng Zhixian’s arrest, several cadres of the Technical Committee were assisted in the investigation, and Liao Wancheng, a former senior vice president of SMT and vice chairman of the SMT Technical Committee, did not know where to go because he was closely related to the case.

It is reported that Hon Hai Group has more than 30 technical committees, which are responsible for procurement and project audit in a certain professional field. In addition to SMT technical committee, there are IE (production engineering) technical committee, automation technical committee and institutional product technical committee. The personnel of these technical committees have certain decision-making power in procurement.

A person familiar with the operation of Hon Hai Group’s Technical Committee revealed that the role of the Technical Committee in procurement is similar to the "expert committees" of many domestic bidding centers. When it comes to the production technology and production technology in the professional field, it is necessary for the Technical Committee to review the rationality of the product production technology.

It is this system design that invisibly gives Deng Zhixian and other key people of the Technical Committee the core purchasing power. It is reported that in 2012, the purchase amount of SMT where Deng Zhixian was located was as high as 10 billion yuan, and Deng Zhixian, who has been in charge of SMT for many years, has thus become an important link for suppliers from all walks of life to "supply".

However, walking too much at night is easy to hit ghosts. Authoritative sources told reporters exclusively that because the people involved in other cases disclosed the details of Deng Zhixian and others’ demands for bribes in order to make meritorious deeds. In September 2012, the Shenzhen procuratorate arrested Deng Zhixian. It is reported that after learning the case, Guo Taiming, chairman of Hon Hai Group, made it clear that he hoped that the mainland police could dig deep and completely eradicate the "moths" in the procurement process of Hon Hai Group.

At the same time, Shenzhen government officials also attached great importance to this case. An ordinary bribery case is particularly sensitive because of Hon Hai’s important position in Shenzhen’s economy. It is reported that all parties are fully investigating the involvement of other higher-level personnel behind Deng Zhixian. As the case is still in the detection stage, the reporter’s interview was also declined by the relevant departments in Shenzhen.

Earlier, Taiwan Province media reported that Li Jinming, chief executive and commercial officer of Hon Hai Group, received a report letter in September 2012, accusing SMT executives of soliciting bribes from suppliers for a long time. So Guo Taiming asked to report the case to the mainland public security department, and asked Li Jinming to form a project team to conduct an internal investigation. The local criminal bureau in Taiwan Province has received a report from Hon Hai, and has consulted the mainland public security bureau to assist in the investigation, and more than 10 Hon Hai executives have been assisted in the investigation.

Hon Hai Group issued a statement on many cases involving senior officials of Hon Hai disclosed by Taiwan Province and other media before, saying that most of them were not in line with the facts. However, Hon Hai also said that Chairman Guo Taiming had instructed that the fraudsters and their reasons would be strictly investigated, and the related incidents would not be allowed to happen again.

There are loopholes in the "perfect" procurement system

"In addition to colluding with the business group bosses, technical committees like SMT also have the dominant position in equipment procurement."

On the surface, Hon Hai’s procurement system is standard.

A former Hon Hai employee who has been engaged in procurement told reporters that its procurement system is mainly divided into BOM (Bill of Materials) procurement and non-BOM procurement. Among them, the BOM part is the accessories and raw materials needed to produce products, and most of them are consumables; Non-BOM procurement refers to the production materials needed in the production process, including equipment, accessories and so on.

The standardization of Hon Hai’s procurement system is reflected in the strict screening of suppliers. Before purchasing all products (BOM and non-BOM), the supplier must have complete legal person qualification, and the product safety must meet various certification requirements. During the screening process, the supervisors of the four departments, namely, production management, quality control, industrial management, and financial management, will be arranged to inspect the factory. However, if the procurement involves non-BOM equipment or products with specific production process on BOM, the Technical Committee will conduct the final review. Only after passing the examination can the supplier be issued a code, which means that it has obtained the procurement qualification.

After screening the suppliers, the products must be tested. After the sample is qualified, the quotation will be started. Hon Hai is good at price comparison, so buyers will often ask for COST DOWN, which will bring greater profit pressure to suppliers.

After a supplier signs a supply contract with Hon Hai, he can get the supplier code, but this does not mean that he can be a Hon Hai supplier safely. The quarterly evaluation will directly affect the qualification of its suppliers. Every evaluation is still the responsibility of the people on the four pipelines: production management, quality management, industrial management and management.

The four pipelines are a unique management method creatively established by Hon Hai. These four management departments are independent but closely coordinated to monitor and manage the daily production and operation of the enterprise. This management system seems to be "perfect", and it seems difficult for suppliers to handle four responsible persons at the same time. But it’s not. Usually, the heads of the four major pipelines are subordinate to the vertical departments under the business groups (there are many business groups under Hon Hai Group, which are in charge of different sectors). "If the boss of the business group says hello, the situation will be different."

"In addition to colluding with the business group bosses, technical committees like SMT also have the leading role in equipment procurement. Although the people of the four major pipelines must check, the technical Committee is the last to sign. Moreover, if any one of the four major pipelines does not sign, the Technical Committee can put pressure on them to push the procurement through. " An employee who has worked in Hon Hai for many years in production management told reporters.

Jia Su (a pseudonym), a senior official of a Shenzhen enterprise who has cooperated with Hon Hai for more than ten years, admitted to the reporter that Taiwan Province enterprises such as Hon Hai and Inventec are different from Taiwan Province family enterprises that entered the mainland in the early days. "In Taiwan Province family enterprises that entered the mainland in the early days, from the finance to the boss, they rarely choose bribery to get purchase orders, but now Taiwanese cadres (Taiwan Province cadres) who have great power in Hon Hai enterprises can become a shortcut for suppliers to get orders. In Hon Hai, as long as you dare to spend money on Taiwan, many things are easy to handle. "

Under the circumstances that power is too centralized and cadres lack self-discipline, Hon Hai’s strict procurement system encounters great challenges.

Anti-corruption shock wave

Hon Hai’s supplier system is experiencing not only shocks, but also internal adjustments.

After Deng Zhixian’s bribery incident was exposed, some enterprises that have cooperative relations with Hon Hai are also suffering from the impact.

It is reported that Hon Hai has terminated its cooperation with the supplier Shenzhen Telu. Shenzhen Delu mainly produces electronic product testing equipment, etc. However, at present, German law does not recognize bribery. However, after many investigations by reporters of China Business News, it can be confirmed that the SMT supporting enterprise located in Dongguan for Hon Hai has been involved. It is reported that with the further investigation of Deng Zhixian’s case, Hon Hai’s supply chain will be adjusted accordingly.

Hon Hai’s supplier system is experiencing not only shocks, but also internal adjustments. Recently, Hon Hai employees disclosed to reporters that the IGDBG (New Green Number) business group has been dissolved in Hon Hai’s bribery storm, and the personnel diversion has basically ended.

"I have already agreed to leave my job. At present, many people have left, and I am the only one left in our department." An employee of the original IGDBG (New Green Number) business group told the reporter, "It is said that the reason for the dissolution is the commercial crime of the relevant person in charge of IGDBG. The business group has suffered losses for two consecutive years, but he and several of his best friends have eaten kickbacks. Eating too much made Guo angry. "

According to insiders, after the notice of dissolving the business group was issued, the employees of IGDBG’s original production line responsible for TV and LED were all diverted to CCPBG (consumer electronics products) business group, and the employees of tablet computer production line were diverted to FIH (Foxconn International). Some employees said that the treatment given by CCPBG was unacceptable. In just over two months, thousands of people left their jobs in the diversion.

IGDBG new green number business group was established in early 2012, which was reorganized and renamed from TMSBG business group (Technology Merging Services Business Group) established in June 2009. Since 2009, a production and research base has been established in Hengyang, Hunan. Our main business is to develop and manufacture e-books, tablet computers, electronic photo frames, LED energy-saving lamps, smart air filters and other products, and we are a global supplier of E-Ink e-books and digital photo frames. IGDBG was originally an important business group of Foxconn’s product innovation and transformation, but since its establishment, it has suffered losses continuously in the past two years. Guo Taiming has repeatedly warned that he hopes to turn losses into profits.

The new green number business group, which was established less than a year ago, was abolished. For Hon Hai, is it to adjust the department by fighting corruption, or are there other considerations? In this regard, as of press time, Hon Hai has not yet responded.

Hon Hai said a few days ago that it has revised the procurement procedures and strictly controlled the supervisor’s ethics, and will not allow similar incidents to happen again. However, in the supply chain management department, there is no institutional revision document released on a large scale. "Foxconn’s regulatory system has been standardized, but corruption cases still need to be reflected from the institutional level." A Foxconn management cadre said.

From August 24th to 26th, tao dance theater’s "Digital Series" modern dance "11" held its world premiere at Beijing National Grand Theatre. Tao’s "digital series" works of body always regard the movement characteristics of body as an important channel for artistic exploration, and then release vitality in the repetitive and restrictive movement of body, and refine a unique aesthetic presentation and training system. How to move? Why are you moving? Spirit and flesh generate speculation in the dynamic law.

The work "11" is the 11th work in the "Digital Series", which is the latest and the longest performance. It lasted 62 minutes on-site observation by The Paper reporters. It is reasonable to say that it is a great challenge for Tao’s body to move for more than 30 minutes-this time, the choreographer Tao Ye tried to break through this limit through paragraph promotion and improvisation.

The performance at the National Grand Theatre is divided into the first half and the second half. In the first half, five dancers from tao dance theater performed the work "5", which was premiered at the July Dance Festival in capital theatre, Amsterdam in 2013. On the stage, the five dancers kept connected with each other from beginning to end, never separated but integrated, and like a knot, they performed endless deformation and progress with continuous support movement. Tao Ye, a choreographer, once explained, "This is a work that expresses people’s understanding and feelings about things."

In the second half of the performance, the style of painting changed suddenly. Perhaps to show the difference from the previous choreography paradigm of "Counting for Series", driven by the strong electronic music rhythm, 11 dancers lined up vertically, mumbling the beat, and uniformly "swept" across the stage, while the upper body showed different dances-this is precisely the characteristic of the work "11". This time, the dancers were set a real-time and common rule of restriction and opening up: lower body limit, lower body limit, Each dancer goes back and forth in her own independent path. The space of their hipbone rotation, the orientation of their knees and every step of their feet are fixed, while the shoulders, elbows, wrists, trunk spine and head of their upper bodies are free to stretch and dance at random. In this sense, every stage presentation of "11" is unique and unique.

If the number "11" is visually two "1s" in parallel, giving people the impression that it is extremely hard and independent, this time, the work "11" is undoubtedly more direct and sharp. The previous digital series is a kind of development and progression in a cycle of repetition. This time, the choreography edifies the works, pushing each paragraph to their respective ends, either accelerating, static, intense or gentle, and then making them meet again, just like the disorder and irregularity of the world. When the dancer’s lower body movements are completely limited, while the upper body is improvised by the dancer according to each current feeling. In this way, 11 dancers seem to talk in reason and sensibility: 11 dance segments are independent of each other, which can be combined, disrupted and reorganized. When the order exits, the stage is left unknown and presents infinite possibilities.

At the end of the performance, the dancers still stood in a row vertically, and returned the stage to the dark field in a uniform way … When the lights came on again, Tao Ye stepped onto the stage and saluted his partners. Everyone is still bowing in a unique style: holding their chests, bowing their heads, bending over, and dropping their hands to the ground … from heaven to the ground, with a heavy curtain call.

"Improvisation is not casual" Freedom is more brain-burning.

Twelve years after its founding (tao dance theater was founded in 2008), when the world talked about modern dance in China, Tao Body had already become an unavoidable name. This is not only because Tao Ye is determined to explore the pure body, but also because he insists on integrating the philosophical thinking and implication of oriental culture into choreography and presentation. For the work "5", it is the musician Xiaohe who integrates the five elements of Jin Mu’s fire, water and earth into his creation, from cosmic sound to secret mantra, from baroque to neoclassical, just like a visual symphony, and makes a contrast between change and unchanging.

When it comes to the idea of "11", Tao Ye explained, "The number 11 is a palindrome for me. It corresponds and opposes, it is not in harmony, but also in contrast, with the beauty of symmetry and the truth of speculation. The number 11 is particularly direct to me, without giving an absolute answer. It provides me with a contradictory and harmonious idea to form a work, and I hope to connect and reach everyone’s deeper inner feelings through this work. "

How to form works by improvisation is a world problem and a challenge that Tao Ye has always wanted to try. He didn’t mince words, "I hated improvisation at first." But now, he began to realize that improvisation is the same as our life. "Everyone, every day, every moment, is improvising." Every behavior, every sentence, every feeling also comes from the improvisation of the moment. " He began to realize that in this era, there may be opportunities to merge the classic and experimental uncertainties with each other. As Tao Ye said, "Improvisation is not casual". What he wants is limited physical freedom.

For "11", the discussion within the dance troupe is unprecedented "warm". Some people think that once hard works are being dismantled by artists themselves, and some people seem to see the vibrant dense jungle, and the works are full of vitality as always; Some people ask "Improvisation under restrictions is not improvisation", while others answer "All improvisation is not improvisation"; Some people have found new surprises in free exploration, others are used to the structure and are trying to break through the singularity. Some people also think of themselves alone in the crowd on the difficult road of life.

"11" has 11 dances, including solo dance, duet dance, trio dance and different group dances. As a solo dancer, Yan Yulin is full of expectations, but she can’t help complaining that "she has to have two heads". One is racking her brains to think about how to be different, and the other is keeping up with the slow pace. Stand neatly in a row on your legs, but try your best to grow differences on your upper body. Dancers have said that they are experiencing division and integration from top to bottom, from left to right, and from inside to outside, and their movements are considered to be brain cramps. It turns out that the quest for freedom has never been that simple.

"Come to an impromptu exploration" into the electronic music and fashion of the theater

Or edify the final word, "Improvisation is not just a concept, it can be concentration, listening, dialogue, courage, collaboration, creation, imagination … and yourself. Although every day will not be repeated, through impromptu exploration, every second can be reborn. Improvisation is as old as human civilization and is the innate ability of human beings. " He believes that everyone, "this time, both dancers and audiences are participating in this work in their own way."

Whether dancing or life, every moment is full of unknowns and improvisations. It not only challenges the dancers, but also expands the imagination for the audience. How do personalities and groups get along? Are freedom and rules either one or the other? On the stage, this is the challenge that choreographers and dancers have to face. Off the stage, isn’t this the answer sheet that everyone has to fill out?

As a partner of Taoye for ten years, Xiaohe once again served as the composer of the new work. The first collaboration between them was to use electronic music in the work "2". Ten years later, they restarted the creation of electronic music because of "11". Yun Gong, human voice, Ruan and symphony, in every cooperation, both of them are exploring different sounds and expanding the boundaries of music. Talking about the music of "11", Tao Ye said that "electronic music is the beginning of my cooperation with Xiaohe, and this 11 pieces of electronic music will be a subversive start again".

This year, Duan Ni and Tao Ye founded their own clothing brand DNTY, which has a more professional team and support in the design and production of clothing. The costume creation of "11" releases more freedom for the body. The spacious and relaxed design makes 11 dancers move like the wind, and Duan Ni also blends the trajectory of body movement with the black and white clothing in the form of images, adding instantaneous flow and complicated visual sense to the stage.

"DNTY four letters don’t have much imagination, which is the initials of surname Pinyin of Duan Ni and Tao Ye. We constitute the genes of this brand. It can also be called DT for short, which symbolizes the TAO of Detail. Clothing and our dancing have something in common. Dancing is a microscopic detail, which is endless and endless in bone transmission. The same is true of clothing. It is not a still life hanging on the wall, but follows the body and keeps talking with your behavior and living habits. " Tao Ye said.

　　People in The Wandering Earth live in underground "underground cities". In the future, "underground cities" will not only exist in science fiction films. Scientists are currently conducting deep space research to explore how to build "underground cities". Recently, the reporter interviewed Xie Heping, an academician of China Academy of Engineering and dean of Shenzhen University’s Institute of Deep Earth Science and Green Energy, and asked him to describe the future survival of underground space from a scientific perspective.

　　"Underground City" is a world-class frontier scientific research.

　　"The development and utilization of deep space is not just science fiction, but a scientific research project that is being studied all over the world, and it is a frontier scientific research topic in the world." Xie Heping said that the comprehensive utilization of underground space has attracted great attention internationally, and many international organizations have been studying the utilization of underground space. These international organizations include the International Association for Tunnels and Underground Space (ITA) established in 1974, the International Joint Research Center for Underground Space (ACUUS) established in 1996, and the International Trenchless Technology Association (ISTT) established in 1986. The Tokyo Declaration, adopted by the International Conference on Urban Underground Space in 1991, also emphasized that "the 21st century will be the century of human exploitation and utilization of underground space", and predicted that one third of people will live in underground space in the future.

　　According to Xie Heping, there are many cases of scientific development and utilization of underground space in the world. For example, an underground park has been built in Finland, which will turn the space 120 meters underground into an oxygen bar with salty and humid air. The constant temperature is 11℃~12℃ all year round, and there are almost no allergens and bacteria, which can recuperate patients suffering from respiratory tract, tuberculosis and other diseases. The mine playground in North Wales, England, which was built in 2014, is 150 meters underground and has the world’s largest underground trampoline in a thermal insulation and moisturizing environment.

　　Many countries are also trying to develop underground space. For example, Singapore plans to build an underground science and technology city, which is equivalent to 30 floors underground in the Western Science Park, to be used by biomedical industry and life sciences, and to accommodate new population in the future.

　　"The total area of a city is not only the ground area, but the total utilization space of a city should be multiplied by 40% of the development depth. These underground spaces have unique advantages such as constant temperature and humidity, sound insulation and isolation, natural resistance to natural disasters, low background radiation and clean environment. " Xie Heping said that using the advantages of these underground spaces can carry out underground medical research and treatment, such as Hodgkin Cave in Uzbekistan, which can improve the cellular immunity of patients with chronic obstructive pulmonary disease; Related scientific research activities can also be carried out. For example, the Large Hadron Collider in Europe is 92 meters underground. "If more exploration and utilization are carried out, it is possible to make deep space a better way of human migration than space settlement and coping with future earth disasters in the future." Xie Heping said.

　　How to build a future "underground city"

　　How to build an underground city in the future? Xie Heping introduced his academic article published in Journal of Coal Industry recently, and put forward his strategic conception and scientific research demonstration on the construction of version 5.0 of "Underground City". According to this idea, 0~50 meters underground is underground rail transit, pipe network system and refuge facilities, 50~100 meters underground is underground livable city, 100~500 meters underground is underground agriculture, underground medicine and underground ecological circle and strategic resource reserve, and 500~2000 meters underground is underground energy circulation belt, underground pumped storage, compressed air power station, underground thermal energy and other storage and utilization, and more than 2000 meters underground is underground.

　　"Regarding the development and utilization of deep space, I put forward the concept of five eras, including the 1.0 era of passive underground space utilization, the 2.0 era of scientific development of underground space and underground ecological city, the 3.0 era of deep ecological circle construction, the 4.0 era of deep scientific laboratory and deep space capsule, and the 5.0 era of liquid mining of deep solid resources." Xie Heping said.

　　The 1.0 era of deep development is to build air-raid shelters, warehouses, subways, underground shopping malls, underground parking lots, etc. In the 2.0 era, there will be a complete and livable eco-city, with sunshine, self-circulating water pumps and intelligent air regeneration systems. In the 3.0 era, there will be ecological and environmental underground space utilization, and the environment of underground ecological circle will be constructed, including artificial sunshine, ecological vegetation, deep farming and animal husbandry, water and ecological self-circulation system, etc. In the era of 4.0, in-situ scientific experiments with different depths should be carried out, and theoretical systems of deep physics, biology, medicine and rock mechanics should be constructed to lay a theoretical foundation for human beings to March into the deep part of the earth.

　　In the 5.0 era, it is necessary to invent shield mining, separation, charging, gasification and power generation integrated technology and equipment to directly transform solid resources into liquid, gas and electric energy. By that time, underground roadway mining will be patrolled, inspected and operated by drones and robots. Using the energy generated by coal powder explosion and gas explosion, in-situ power generation will be carried out at a depth of 3,000m underground, and the electricity, hydrogen and liquefied carbon will be transported to the ground instead of solid resources, and a self-circulation development and utilization system with deep in-situ ecological green and low carbon will be built. "At present, the doctoral team led by me is doing pre-research in this area." Xie Heping said.

　　Step into the era of "Dungeon" 2.0

　　According to Xie Heping, the earth’s solid mineral resources can be buried more than 40 kilometers, and 70% of China’s proven iron ore, copper ore and bauxite resources are below 2 kilometers. Take geothermal resources as an example, there is 125.4 billion thermal energy in the outermost 10 kilometers of the earth’s crust, which is equivalent to 2000 times of the total thermal energy of coal produced in the world.

　　At present, China has listed deep-seated development as a major national science and technology project, and it is necessary to comprehensively improve the level and ability of deep-seated engineering science and technology, and strive to reach 15,000 meters by 2035; Oil and gas exploitation should reach 10000 meters; Geothermal development to 6000 meters, solid resources mining to 3000 meters, underground space engineering to 1000 meters.

　　"At present, the utilization rate of underground space in the world is about 30%, while in our country it is only 17%." Xie Heping said that with the development of China’s deep development strategy, how to rationally develop and utilize these underground spaces is "a major national strategic scientific research project that needs pre-research first".

　　"Taking coal mines as an example, the existing underground space of coal mines in China is about 13.9 billion cubic meters, and it is expected to reach 24.1 billion cubic meters by 2030, with a length of about 1.6 million kilometers, which can circle the equator 40 times. How to use such a huge underground roadway space? " Xie Heping said that the transformation and utilization of waste gas mines in foreign countries have many uses and forms. For example, using geothermal energy to develop underground agriculture, scholars at Nottingham University are considering using geothermal energy naturally existing in mines to transform 150,000 abandoned coal mines into underground farms.

　　"We must know that the underground itself is warm in winter and cool in summer, and the construction cost of underground greenhouse is only 1/4 of that of ground greenhouse agriculture." Xie Heping said that in 2017, an underground farm was built in London, England, using an air-raid shelter 33 meters underground. With LED lights as the light source, hydroponics technology can save 70% of water, no pesticides are needed at all, and plant growth is not affected by seasons and weather. It can be harvested in 6 to 28 days, and the underground agricultural product brand has been successfully launched.

　　"There are also ways to build a small intelligent underground parking garage, underground pumped storage power generation, compressed air storage power generation station, etc., which can be tried in the utilization of underground space." Xie Heping said that underground sewage treatment plants can also be built. For example, Hong Kong plans to put all surface sewage treatment underground; You can also build underground hotels, carry out landscape tours and underground in-situ laboratories. For example, the dark matter laboratory in South Korea is 700 meters below the mine.

　　In the aspect of deep space utilization, China has also begun some explorations. At present, the first phase reconstruction project of the five major coal mines in the west of Beijing has been started. Xie Heping said that according to the plan, the ground is green mountains and green waters scenic area, college education and training area, tourist resort area, sports and leisure area and high-tech park, and the underground will be developed into underground coal mine safety production training practice area, underground ecological landscape experience area, underground agricultural planting area and deep scientific exploration area. "We hope to turn it into a national demonstration area for the development and utilization of coal mines, a headquarters for scientific research and development and an experimental base for underground space research and development." Xie Heping said. In his view, regarding the construction of "underground cities", "it has just entered the 2.0 era, and it may take decades or even hundreds of years to reach the 5.0 era, but we can imagine the future trends and bright prospects."

The construction of transportation infrastructure can promote the flow of people and create employment opportunities, thus contributing to Kenya’s economic transformation.

According to foreign media reports, NASA said that five asteroids will pass by the earth in the future, and one of them may be very close to the earth. It is reported that the smallest diameter of these asteroids is only 8 meters and the largest is 90 meters, and lular distance from the Earth will be as short as five distance to the moon.

Image source network

A distance to the moon refers to the distance between the earth and the moon, which is about 238,900 miles (384,000 kilometers). It sounds like a long distance, but it is a very close distance in the vast space, and they will pass by the edge of the earth. Fortunately, the closest asteroid to the earth this time is smaller in diameter and will not pose too much threat to the earth.

Where are the asteroids?

Asteroids are celestial bodies in the solar system that move around the sun like planets, but are much smaller in size and mass than planets. Most of them are influenced by the gravitational force of the sun and Jupiter, and they gather in the asteroid-intensive area between the orbits of Mars and Jupiter. According to the statistics of 120,437 asteroids that have been numbered, this hotbed of asteroid "life" is composed of more than 500,000 asteroids. So many of them are called "main belt" and many people are used to calling it "asteroid belt".

Figure: Asteroid belt

The so-called "near-earth asteroids" can be understood very well just by looking at the literal meaning. "Near-earth" means that their orbits are very close to the earth, and they are a special group that deviates from the main belt.

Dangerous asteroid

According to analysis, only asteroids with a diameter of more than 140 meters and a minimum distance from the Earth of less than 0.05 astronomical unit (about 7.4 million kilometers) will be included in the list of dangerous asteroids.

According to the latest release of the website of the International Asteroid Center, researchers have discovered 1,640 "potentially threatening near-Earth asteroids" through global joint survey.

History of asteroid impact on the earth

As early as 65 million years ago, dinosaurs, a large animal that dominated the earth for 150 million years, suddenly disappeared. Astronomers speculate that there are two possible reasons for the extinction of dinosaurs: first, the explosion of supernovae, which is equivalent to about 10.24 hydrogen bombs, led to the extinction of dinosaurs; The second is asteroid impact. In 1978, American astronomer Luis Alvarez speculated that an asteroid hit Iceland, and this impact was equivalent to the energy of 1 trillion tons of TNT. Such a violent impact led to the disappearance of dinosaurs.

In addition, on June 30, 1908, a huge flash of light lit up the sky in the Tunguska River Basin in Shiquan, krasnoyarskiy kray, Siberia, followed by a violent explosion equivalent to 1,000 atomic bombs. A mushroom-like cloud of smoke soared 12 miles into the sky, and the scorching air billow swept the vast Taiga forest one after another, and hundreds of square kilometers of forest were destroyed in the explosion. This famous explosion was the Tunguska Big Bang.

In addition, according to the latest research report of geoscientists from the Australian National University (ANU), at least three asteroids with a diameter of 20-50 kilometers collided with the earth 3.2 billion years ago, which greatly changed the structure and elemental composition of the earth’s surface.

In recent years, scientists predict that an asteroid named Apophis will pass by the Earth in 2029 and hit the Earth in 2036. If it hits the earth, it will generate energy equivalent to the explosion of 110,000 atomic bombs, which is equivalent to the instantaneous destruction of the whole city of new york and its surrounding areas. If it hits the ocean, it will cause a devastating tsunami, which is more violent than the 2004 Indian Ocean tsunami.

Apophis is one of nearly 800 potentially threatening asteroids known to astronomers.

Prevent collision and defend the earth

In order to cope with this possible impact, some people put forward a plan to destroy asteroids with nuclear weapons. However, all the accumulated nuclear weapons on the earth are only enough to blow up an asteroid with a diameter of 9 kilometers, and they have to hit the center accurately. In addition, the consequences of a nuclear explosion in the universe are unpredictable.

Therefore, people are also considering other plans to deal with asteroids, such as using lasers or lead ingots. NASA is going to lure Apophis away with a "gravity trailer" when it flies to the Earth in 2029. When the asteroid passes near the Earth in 2029, it only needs to launch a "gravity trailer" spacecraft weighing about 1 ton, which can change the orbit of this asteroid. According to astronomers’ calculations, Apophis will slightly change its orbit when it flies over the earth this time, but when it returns again in 2036, the possibility of colliding with the earth is very small, only 1 in 5,000.

Although the speculation about the extinction of dinosaurs makes the prediction of the impact of asteroids on the earth scary, with the development of science and technology, from not knowing what asteroids are to accurately understanding and then boldly predicting, the progress of civilization makes us believe in the power of science, and there must always be a perfect way to deal with this "uninvited guest".

"The province has successfully passed the three peaks of fever clinics, emergency departments and critically ill patients. The epidemic situation in rural areas that have received much attention has not rebounded significantly, and the overall epidemic situation in the province is stable and orderly." On the morning of January 28th, on the first working day after the Spring Festival holiday, the Provincial Health and Wellness Committee held a regular meeting of the leading group for epidemic prevention and control and a working meeting of the province’s health and wellness system. Xu Bin, deputy director of the Provincial Health and Wellness Committee, informed the situation at the meeting.

The normal medical order was gradually restored during the Spring Festival.

No new virus sequence was found.

The Epidemic Prevention and Control Group of the Provincial Health and Wellness Committee gave a set of data: the peak of infection in Covid-19, Sichuan Province has passed, and the trend of new infections is obvious. During the Spring Festival, all localities insisted on multi-point monitoring of the epidemic situation in COVID-19, and 110 virus genomes were sequenced, and no new virus sequences were found; No large-scale infection occurred in 3078 civil affairs service institutions in the province.

"During the Spring Festival, the number of positive patients and critically ill patients in the province continued to decline, and there was no obvious treatment of small peaks and insufficient medical resources, and the normal medical order gradually recovered." The Medical Treatment Group of the Provincial Health and Wellness Committee released a preliminary statistical result: from January 1 to January 27, the bed utilization rate of medical institutions above the second level dropped from 96.89% to 60.04%, and the bed utilization rate of ICU dropped from 87.50% to 49.73%. The number of positive patients in the hospital dropped from the highest of more than 80,000 in the previous period to more than 8,000, and the medical order recovered well.

Behind the figures is the continuous optimization of the province’s epidemic prevention and control measures. Taking medical services for key populations as an example, during the Spring Festival, Sichuan provided key populations with "three observations" (observing whether there is "silent hypoxia" performance, observing whether the health condition is abnormal, and observing whether the basic diseases are aggravated), "two tests" (antigen testing, temperature testing) and "one door-to-door" (door-to-door health package distribution) services at least twice a week, and carried out a total of 2.726 million health services; Counties (cities, districts) have set up more than 8,800 "roving diagnosis and treatment teams" in villages and towns, making rounds of clinics in township hospitals, villages with complicated conditions and nursing homes, providing medical treatment and health monitoring services to the masses face to face, and co-ordinating the distribution of medicines and necessary equipment to township hospitals and village clinics. Before and after the Spring Festival, the province’s health system also carried out the activities of "going to the grass-roots level, inspecting the facts, and making a big visit", guiding all localities to establish a daily monitoring and scheduling mechanism for drug reserves, and dynamically adjusting the reserves of drugs and testing reagents. Before the holiday, more than 90,000 finger-clip oximeters were provided free of charge for 44,800 village clinics in the province.

The possibility of a large-scale local epidemic in the near future is low.

But there are still uncertainties.

During the Spring Festival, the epidemic situation was stable and orderly. What do you think of the next step? How to do it?

Zhou Jiushun, an expert on epidemic prevention and control and deputy director of the Provincial Center for Disease Control and Prevention, judged that the epidemic situation fluctuated at a low level during the Spring Festival, and the possibility of a large-scale local epidemic and the importation of new strains causing a large-scale epidemic was low, but everyone should continue to be the first responsible person for health.

"At present, there are still uncertainties in the epidemic situation in COVID-19. All localities should continue to strengthen epidemic monitoring and situation analysis, and do a good job in prevention and control of key institutions in a targeted manner." Ma Jun, the relevant person in charge of the epidemic prevention and control group of the Provincial Health and Wellness Commission and director of the CDC, said that the next step would be to pay close attention to the introduction and spread of mutant strains in Covid-19, and to strengthen the epidemiological investigation of severe and dead cases, the protection of key populations, vaccination, epidemic prevention and control in rural areas and health services.

Li Bing, the relevant person in charge of the medical treatment team of the Provincial Health and Wellness Commission and director of the Medical Administration Department, said that the specified frequency of not less than 3 times and 2 times per week will continue to be strictly implemented, and full coverage health services will be provided to the key and sub-key populations in the province. Relying on the three-level severe treatment system in provinces, cities and counties and the piecemeal consultation mechanism in four high-level general hospitals such as west china hospital and Provincial People’s Hospital, the sinking and centralized treatment of experts will be strengthened, the treatment of critically ill patients and the co-treatment of multiple diseases will be highlighted, and the normal medical order will continue to be gradually restored.

Xu Bin said that the next step will be to focus on key places, key populations and key institutions to ensure that medical services, drug equipment, protective materials, vaccination and referral mechanisms are in place; Continue to strengthen the monitoring of new mutant strains in Covid-19, pay special attention to the monitoring of mutation imported from abroad in Covid-19, and provide decision-making basis for early epidemic warning; Strengthen the construction of compound, integrated and leading professional talents in general hospitals and disease control institutions.

New energy has become the general trend of car purchase at present, and various car companies have also laid out various products in different price ranges, and mini-cars are naturally a good choice that cannot be avoided. Most consumer use scenarios are mostly commuting to work, buying food and picking up babies, etc., which often put Yan value in the first place. In addition, small and easy to drive, low car cost and other factors are also key considerations. Today, let’s take a look at the highlights of this Pentium pony model.

Pentium pony is the representative work of FAW Pentium micro electric vehicle, and it is a pure electric car. Indeed, no matter in design or product positioning, the new car is unique in the micro electric vehicle market. The car is positioned as a 3-door and 4-seat mini electric vehicle close to Wuling Hongguang MINIEV. The car competes with popular models such as Hongguang mini EV, Chery QQ ice cream and Chang ‘an waxy corn, bringing users a new choice of micro-electricity market differentiation.

Regarding the appearance, the design of Pentium pony can be described as cute. Its big eyes and unique taillight design make people fall in love at first sight. Compact body size, suitable for shuttle in the city, two-color contrast body appearance, full of personality. I often get some curious and appreciative eyes because of the lovely appearance of the vehicle, and I feel quite happy. Chang ‘an "waxy corn" has a round body, and the front headlights are like an enlarged corn grain. It is reported that Pentium Pony offers 6 body colors, including lime, cherry, grape, blueberry, lychee and pearl lychee.

Coming to the side, the whole is quite compact, with a layout of three doors and four seats, while Chang ‘an waxy corn also adopts a layout of three doors and four seats. The wheel eyebrows on both sides of the Pentium pony cooperate with the white rearview mirror to enhance the overall sense of movement. In addition, the new car also uses low wind resistance wheels, which is more fashionable. The rear design has a clear echo with the front face.

In terms of configuration, Pentium pony also performed well. The central control retains many knob designs, which are simple and intuitive to operate, and a LCD instrument is in front. Although the interior space is small, the layout is reasonable. The whole system comes standard with the main driver airbag and the new generation EPS steering system. Chang ‘an waxy corn is also equipped with double airbags in the front row, reversing radar/image, uphill assist, multi-function steering wheel, 7-inch LCD instrument +10.25-inch central control screen, main driver’s cosmetic mirror and other configurations. In terms of interior color matching, Pony provides five fresh interiors, including Tiffany Green, Sakura Powder, Glazed Blue, Clear Blue and Time Gold. Compared with Chang ‘an waxy corn at the same price, Pentium pony has a more complete configuration.

Next, let’s talk about dynamic performance. Although the Pentium pony is a miniature pure tram, its power is not inferior to other similar models. Pentium pony is equipped with a single motor with a maximum power of 20 kW. Fast acceleration and flexible steering make you feel comfortable in busy urban traffic. The charging time of this model of Chang ‘an waxy corn is 9.8h, and fast charging is not supported.

Summary:For consumers, if they want to buy a pure electric mini-car to travel instead of walking, the product strength of this Pentium pony will indeed be more cost-effective. Pentium pony’s more distinctive product strength further enriches the product matrix of Pentium brand and brings diversified choices to users.

　　May 4th (Zhao Jiaran), the client of Sino-Singapore Jingwei, unconsciously, the "May Day" holiday is coming to an end, and the clarion call for construction has sounded again. Whether you are traveling outside or staying in bed at home, have you successfully "returned to blood" after the holiday adjustment? Do you feel a little stressed when you think about the next six working days?

　　With the rise of "decompression economy", merchants have customized many products according to the new characteristics and new demands of consumption, ranging from a few yuan with low prices to thousands or even hundreds of thousands of yuan. Follow Jingwei Jun to see if there is any decompression method you like?

　　1-10 yuan: "Decompression artifact" is favored by office workers.

　　Toys have never been children’s patent. On the Internet, some small toys that focus on decompression and venting have become "online celebrity" products in the adult world because of their novel shapes and creative humor.

　　Searching for "decompression" keywords on the e-commerce platform can find thousands of different commodities. Hot-selling toys include venting dumplings, screaming chicken, decompression Rubik’s cube, fingertip gyro, foaming glue, etc., and the prices are usually relatively low, and they can be purchased in 10 yuan.

　　Zhongxin Jingwei saw on the purchase page of a rubber toy in the shape of a small animal that this kind of toy is called "decompression artifact". Each toy is only sold in 1 yuan, but its monthly sales volume has exceeded 20,000. Judging from the comments, many consumers who buy such toys are adults.

　　Another decompression toy seems to be specially made for working people: an enter key bigger than a mouse pad and connected to a computer, which does have the function of the enter key. The store said that the original intention of this toy design is to vent and decompress, and it will not disturb others. Many netizens who bought this product said: "I used to beat the table, but now my temper has converged!" "The whole office came to clap."

　　However, Zhongxin Jingwei noticed that some buyers reported that the rubber toys they bought had problems such as "strong taste", "serious color fading", "very sticky hands" and "easy to damage". In addition, some decompression toys are not accompanied by certification marks such as quality certificate and manufacturer’s logo when they are delivered.

　　According to media reports, recently, the light industrial products laboratory of SGS Tongbiao Standard Technical Service Co., Ltd. conducted safety tests on 11 decompression toys. The results show that there are 7 toys with potential safety hazards. Among them, boron and lead in a magnetic plasticine exceeded the requirements of EU toy standards; Phthalate plasticizers were detected in online celebrity "Screaming Chicken" samples, which exceeded the national toy standard by more than 400 times. The radiation value of the blue LED lamp in the luminous fur ball is too high, which may cause retinal damage.

　　It seems that it is really "the decompression is not standardized, and the relatives have two tears"!

　　10-100 yuan: Single white-collar workers are keen on "playing with" service.

　　With the increasing anxiety of urban single youth, the "companion economy" came into being under the birth of "lonely economy". Although the business activities in the form of companionship and chatting have already appeared, there are still new forms in the past two years.

　　Wang Fei (a pseudonym), a 27-year-old single "Beipiao", told Zhongxin Jingwei that she was busy at work on weekdays and had a rather "homebody" personality, and she liked to watch live broadcasts in her spare time. Recently, when he watched the live broadcast, he learned about the "play with" business and wanted to try it on a whim.

　　Many businesses on the Internet have launched "play-along" services. In an online shop consulted by Wang Fei, the customer service said that the play-along price of popular games such as exciting battlefield and League of Legends is the same, which is one game in 12 yuan or one hour in 20 yuan. The store said that the players are all "game gods", which can not only chat during the game, but also help customers improve their game level. According to the difference of customers’ needs, merchants will also provide different play services, and the highest price is in 40 yuan/hour.

　　"It may be mentioned that there are businesses such as playing and chatting. There will always be people who think of the soft porn industry or other illegal operations, but there are many people who simply seek companionship. Just find an interesting teammate." Wang Fei told Zhongxin Jingwei that he now spends about 100 yuan every month on playing, which is equivalent to two or three meals.

　　Some studies have said that the companion economy may be the next billion-dollar market. According to the research released by Guojin Securities Research Institute, in December 2018, the total number of monthly active users of companion apps reached 42.13 million, including 16.67 million free apps and 25.46 million paid apps. In the view of Guojin Securities Research Institute, by 2025 or so, the market scale of accompanying economy may reach the current live broadcast market scale, that is, 40-50 billion yuan.

　　100,000+:Are you there? Take time to go for a walk in Antarctica.

　　It is common practice for many people to travel during holidays to "escape" the pressure in their work and life. At present, with the strengthening of the commercialization of tourist attractions and the rapid development of the domestic tourism market, many travel agencies are seeking differentiated services, and Antarctic travel has gradually entered the public eye.

　　Ms Liao, who lives in Beijing, has already started preparing for her trip to Antarctica at the end of this year. For her who loves traveling, the scenic spots and itineraries at home and abroad are gradually routinized, and the itinerary will more or less include shopping, while the polar regions that were rarely visited before give her a mysterious and relaxing feeling.

　　"Travel agencies require reservations more than 100 days in advance, and only two tours are organized each year, so I can only make an appointment to leave at the end of this year." Ms. Liao said that some people think that this kind of entertainment is expensive and cost-effective, but she thinks that this kind of travel away from the hustle and bustle of the city can not only reduce the pressure of urban life, but also satisfy her curiosity.

　　Wang Kaijun, the founder of Beijing Wuzhouxing International Travel Service, said in an interview with Zhongxin Jingwei that the company has launched Antarctic tourism projects for several years, but in recent years, with the improvement of the internal hardware and the improvement of the itinerary of cruise ships, Antarctic tourism has become more popular. Although the journey is long, and even part of the journey is not so comfortable, the Antarctic still attracts groups of tourists with its unique characteristics.

　　"It takes more than 20 days before and after the Antarctic tour, so many employees can’t take time, but they can still see young tourists." Wang Kaijun said that according to the different modes of travel, the number of scenic spots and the conditions of cruise ships, the charge standard for Antarctic tour of Wuzhou Tour is usually 80,000-100,000 yuan or higher.

　　According to "Chinese Antarctic Tourism Report 2018-2019" released by Ctrip, tourists who book polar travel on Ctrip can spend up to 640,000 yuan for a single person to go to Antarctica or South America+Antarctica, with a minimum of 50,000 yuan and a per capita spending of about 110,000 yuan. According to the report, 46.5% of Antarctic tourists are born after 1980s.

　　In addition, many travel products now take healing and decompression as their selling points, aiming to distinguish them from "punch-in" tourism. The person in charge of Caesars Tourism in Beijing told Zhongxin Jingwei that in recent years, domestic consumers have more diverse ways and choices of travel, and some travel products that focus on relaxing, such as hiking, yoga and meditation, have been favored by urban consumers.

　　There are thousands of ways to decompress, perhaps the one that suits you best is not necessarily the most expensive. In the face of pressure, will you choose to take a sleep to ease it, or reward yourself with your labor income? Please share your unique decompression method with us! (Zhongxin Jingwei APP)

　　Changsha, December 25th (Reporter Xu Zhixiong correspondent Zou Min Zhou Ying) "Our invention has been recognized as reaching the international advanced level." On 25th, Li Lijun, Dean of School of Mechanical and Electrical Engineering, Central South University of Forestry and Technology, proudly said that this newly-developed machine can match the working efficiency of 30 laborers in the past.

　　Tea oil is as famous as olive oil, and is also called "the king of oil", which has unique nutritional value. At the same time, tea oil is also a unique oil species in China, with a history of cultivation and utilization of more than 2,300 years. However, for a long time, because Camellia oleifera grows in the mountains, tea seeds need to be picked completely by hand. "It is difficult to hire people and the labor cost is high" has become a bottleneck that seriously restricts the development of the tea oil industry, and it also directly leads to the continuous rise of tea oil prices, which makes ordinary people discouraged.

　　Therefore, as early as 2009, the scientific research team of Central South University of Forestry and Science headed by Li Lijun began to study the replacement of manual picking of tea seeds with machines. In the past ten years, they have traveled all over the main tea-oil producing areas in Hunan, fully investigated the planting and picking characteristics of tea-oil trees, and constantly tackled technical problems and improved the prototype of tea-oil tree fruit picker.

　　In view of the characteristics of Camellia oleifera forest, such as complex terrain, random tree shape and synchronous flowers and fruits, Li Lijun team listed four kinds of Camellia oleifera fruit picking methods, made nine rounds of prototypes, broke through seven key technologies, and made a lot of prototype tests, and finally the shaped Camellia oleifera fruit picker came out.

　　"This machine not only has a smart ‘ Picker ’ It can be used for various tree-shaped operations and can walk freely in complex environments such as steep slopes. " Li Lijun said that the most important thing is that it can accurately match the energy, so as to achieve only picking the fruits without damaging the flowers or affecting the yield of tea seeds.

　　Li Lijun said that at the just-concluded evaluation meeting of "Research on Key Techniques and Equipment of Camellia oleifera Fruit Picking" held by Hunan Forestry Society, the Camellia oleifera Fruit Picker of Central South Forestry University was recognized as having solved the problems of efficient picking of Camellia oleifera fruit and less flower loss, and the technology realized independent innovation, the equipment was reliable and practical, and the research results reached the international advanced level. "We plan to use one to two years to promote the beautification, multifunction, intelligence and serialization of Camellia oleifera fruit pickers, and realize mass production to benefit the majority of forest farmers."
