Awesome, my C919! The first flight of China big plane is in sight.

  Wu Guanghui, chief designer of Comac C919 and ARJ21, has won the national special prize for scientific and technological progress and the first prize for national defense scientific and technological achievements. A key model won the first prize of China Aviation Industry Corporation I and the first prize of the National Defense Science, Technology and Industry Committee.

  "Many aircraft parts are made in China and fly in the sky every day. C919 has gone through nearly seven years, and has done a lot of design, calculation and experiments. I am definitely willing to take this plane first. "

  — — Wu Guanghui

  These days, in the commercial aircraft test center of China Commercial Aircraft Corporation, the newly-built Zhuqiao test hangar in Pudong is spacious and bright. In the hangar, the landing gear that originally supported the domestic large passenger plane C919 was all put into the landing gear cabin, and three air springs like "jacks" lifted the plane into mid-air. What is going on here is the ground resonance test and modal coupling test of the whole aircraft that must be completed before the first flight, which means that the C919 has officially entered the final sprint stage before the first flight.

  C919 is a domestic large passenger plane independently designed and developed by China. It is a short-haul single-aisle narrow-body passenger plane with more than 150 seats. In the future, it will compete with internationally renowned commercial aircraft such as Airbus 320 series and Boeing 737 series for orders. The manufacturer China Commercial Aircraft Co., Ltd. recently announced that the C919 plans to make its first flight in the first half of 2017 and will fully launch the wide-body passenger aircraft project. It can be said that after nearly 10 years of hard work, China people’s dream of "big plane" will soon become a reality.

  ① Rigorous test to ensure safety.

  To fly into the blue sky, a plane must first practice a pair of steel bars and iron bones. For the C919, which carries the dream of a big plane for Chinese people, the significance of the test is even more significant. This is the first large passenger plane made by China people, and its safety cannot be lost.

  For this reason, C919 has undergone a series of tests like "torture". Among them, the 2.5g static test of the whole aircraft started in early November last year is the most severe and significant one since the birth of the C919.

  This test mainly tests the strain and deformation of the "skeleton" of the body under constant external loading. In layman’s terms, this kind of test is to let the aircraft simulate the stress situation when challenging air flight on the ground, and go beyond the natural limit to verify how much force the aircraft can bear.

  Before the start of the experiment, the researchers covered the whole body with white adhesive tape, which is a resistance strain gauge that can sensitively measure stress and strain close to the surface of the body, just like doing electrocardiogram for the plane. During the test, the load starts to rise at the level of 5%, and the load must be kept for 3 seconds every time. "The structure must be able to withstand the ultimate load for 3 seconds without damage." Zhou Liang Dao, deputy chief designer of the C919 passenger plane, said that the preparation behind the team took more than 300 days for this short three seconds.

  With the continuous loading, the aircraft began to show obvious external reflection, and the wing began to tilt up a little. Finally, when the load reaches 100% of the test outline, the wing tip tilts up to nearly 2 meters, which is highly consistent with the strength analysis before the test, which shows that the test is successful and its strong "bones" and body are enough to support flying into the blue sky.

  This is just a small step in the long March before the first flight of the plane. A passenger plane has to complete 13 static tests in 48 working conditions, including pressurization in the booster cabin, front lifting connection, main lifting connection, whole aircraft condition, vertical tail and rudder, as well as "three-bird test" such as iron bird, copper bird and electric bird and joint test of the whole aircraft system. Therefore, researchers have made independent innovations in system integration experiments.

  In the comprehensive test hall of Shanghai Aircraft Design and Research Institute, the iron bird test-bed with little difference from the C919 real machine looks like an eagle with wings spread and its tail stuck high. Don’t underestimate this test-bed. Its full name is "Integrated Test-bed for Flight Control Hydraulic System", which mainly tests the landing gear, wings and other mechanical systems of aircraft. In order to ensure the authenticity of the system test, the iron bird test-bed is designed according to the 1:1 ratio of the real aircraft, so that the mechanical installation interfaces of the flight control, hydraulic and landing gear systems are the same as those of the aircraft.

  Next to the Iron Bird Test Bench, there is also a "Copper Bird" that tests power supply systems such as power generation and distribution, and also restores the real state of the machine to 1:1 for equipment installation. "Iron Bird", "Copper Bird" and the avionics system test called "Electric Bird" will eventually be all connected, thus forming a "three-bird joint test" to simulate the state of the aircraft.

  In the experiment, researchers conducted a comprehensive test on the aircraft system. Take the avionics system as an example. At most, there are more than 100,000 parameters in a test. These parameters should be tested one by one to find out the possible omissions in the design. "Our goal is not to take the fault to the sky." Yu Shenghui, senior engineer of the General Aerodynamics Department of Shanghai Aircraft Design and Research Institute, said.

  According to the plan, six testing machines are carrying out joint testing of the whole machine system, and customer service engineering and airworthiness work are also being carried out simultaneously.

  ②C919 is genuine China goods.

  As the first large passenger plane with completely independent intellectual property rights in China, C919 has been frequently questioned since it was established in 2006: an aircraft whose engine, avionics core processing system and some materials all depend on foreign products or technologies, why should it be said to be "made in China"?

  In fact, to evaluate the innovation of C919, we may need to draw lessons from a fairy tale named Pony Crossing the River. This story is about a pony crossing a river. A cow next to it said, "The water is very shallow, just without a calf, so you can cross it." But the squirrel in the tree said, "The water is deep and will drown." So, is the river deep or shallow? Finally, the pony got off the river by himself and carefully waded to the other side. It found that the river was neither as shallow as the cow said, nor as deep as the squirrel said. The same is true for the development and innovation of C919. Everyone should not only see the major innovations achieved in the process of aircraft development, but also objectively admit the existing shortcomings.

  According to international standards, judging whether an airplane is made in China or assembled depends on whether it meets three conditions. 1. Who owns the property right of the whole machine? Second, who is the core team to develop the whole machine? Third, who holds the key link in the development of the whole machine? For C919, the answer to these three questions is China.

  The person in charge of Comac in China said that the property right of the C919 is owned by Comac in China. The team of Comac in China is the core of the development, and the key links such as aircraft design, final assembly, test flight and sales are in the hands of Comac in China.

  As for foreign companies providing parts or technology, this is a common thing in the global aviation manufacturing industry. Aviation manufacturing giants such as Boeing and Airbus also use foreign products on many key components when developing aircraft.

  However, for equipment like engines, the C919 chose the LEAP-X1C engine jointly developed by the United States and France, which is the only foreign starting power device selected by the C919. It should be said that the engine is indeed a major constraint in the development of China’s large aircraft, and it can only be sought from people at present. However, I believe that in 10 to 15 years, China will be able to develop its own advanced aero-engine for large aircraft.

  ③ Have a number of scientific and technological innovations.

  Experts said that the C919 was completely designed and integrated independently, with outstanding technical indicators. It is the persistent innovation of researchers who have sharpened their swords for ten years that has led to the high-tech C919, which integrates many key technologies.

  However, what did C919 look like when it was approved as one of the 16 major projects in the national medium-and long-term science and technology planning in January 2006? What difficulties may be encountered in the development? Due to the limitation of western aviation powers in technology introduction, China researchers have no idea and can only cross the river by feeling the stones.

  In November 2008, the C919 project was launched. A large passenger aircraft joint engineering team composed of 468 experts from 47 domestic and foreign units, plus a large passenger aircraft expert consulting group composed of 20 academicians and experts, started from sketches and gradually sorted out the first batch of 14 special technical research projects that need to be started.

  Among these key technologies, there are several that must be mentioned. For example, the "supercritical airfoil" that makes airplanes more fuel efficient. A large passenger airliner is an out-and-out "oil tiger". In order to reduce fuel consumption, the wing design of C919 uses a supercritical airfoil, which improves the cruise aerodynamic efficiency by more than 20% and reduces drag by about 8%.

  Another unique innovation is the adoption of the third generation Al-Li alloy materials. It is the first time in China that the world’s advanced third-generation Al-Li alloy materials are widely used in the main structure of C919. Compared with ordinary aluminum alloy, this lightweight metal material with high damage resistance has greater strength and lighter weight under the same strength, which is very important to realize the weight reduction of aircraft structure and greatly improve the service life of aircraft.

  In addition, as the "brain" of the C919, the avionics system of the aircraft has realized "giving all the work to the network". Compared with the old version of the network, which was widely used before but had limited bandwidth, the new aviation bus communication protocol adopted by C919 not only has high bandwidth but also shares resources, which means that the signals that originally needed to be transmitted through several cables can now be transmitted by one cable. Experts said that this is like we need to run 10 trains from A to B, but we don’t need to build 10 railways. We only need a set of double-track railways and a reliable signal system.

  According to Wu Guanghui, the chief designer of C919, the developers have planned 102 key technical problems, and many advanced materials have been applied on a large scale in domestic civil aircraft for the first time. The development process of millions of parts and airborne systems is highly parallel. In order to overcome these technical difficulties, 22 provinces and cities, more than 200 enterprises, 36 universities and hundreds of thousands of industrial personnel participated in the development of C919 large passenger aircraft, and 16 material manufacturers and 54 standard parts manufacturers including Baosteel became suppliers or potential suppliers of large passenger aircraft projects.

How should humans and wild animals get along?

  Author: Zhang Wenjuan (Senior Director of China Ecological Civilization Research and Promotion Association)

  The severity and complexity of the COVID-19 epidemic far exceeded people’s expectations. Today, the host or intermediate host in novel coronavirus is considered to be related to wild animals such as bats or pangolins. Throughout the world’s major epidemics in human history, almost every time is related to wild animals, which further forces us to reflect: how do humans and wild animals coexist and coexist?

  On November 16, 2019, at the Daqinghe Bird Rescue Station of Laoting County Wildlife Conservation Association in Hebei Province, the staff released an ordinary horseshoe crab. Xinhua news agency

  Wild hosts of deadly viruses or bacteria.

  The struggle between human beings and viruses or pathogenic bacteria has never stopped.

  Plague is caused by a microorganism named Yersinia pestis. Besides mice, there are other common rodents and wild carnivores as the host animals. Besides these animals, there are fleas parasitic on them. The first recorded plague pandemic in human history occurred in the 6th century A.D., originated in the Middle East, and spread to North Africa and Europe through Egypt, killing nearly 100 million people. At that time, the total population of the world was only over 200 million. The second plague began in the mid-14th century, and in 300 years, the European continent lost 1/3 to 1/2 of its population. The third plague pandemic began in the second half of the 19th century, and it first broke out in Yunnan, China, and then broke out in South China, North China, Northeast China and other countries such as Europe, Asia and Africa.

  In 1976, a terrible disease broke out in Sudan and Zaire in West Africa, and the patient died quickly after high fever and systemic bleeding. Scientists found a new virus in the body of the deceased and named it after Ebola, a beautiful river in West Africa. This is a typical zoonotic infectious disease, and mammals such as humans, apes, porcupines, antelopes, monkeys and fruit bats may be infected. Scientific research suggests that fruit bats may be the natural reservoir of Ebola virus.

  Marburg virus is a close relative of Ebola virus. The virus first appeared in Germany in 1967, 31 people were infected and 7 people died. The source of infection was traced back to a group of African green monkeys from Uganda. The largest Marburg virus epidemic on record occurred in Angola, Africa in 2005, when the mortality rate was as high as 90%. At present, there are 12 outbreaks of Marburg virus, the most recent of which was in Uganda in 2017.

  SARS, a disaster that is still fresh in our memory, has a mortality rate of 11%. SARS coronavirus is the same as novel coronavirus coronavirus. At first, some people thought civet cats were the host of the virus, but after more than ten years of follow-up research, scientists detected the gene residue of SARS virus in the body of Jutoubat, and thought that Jutoubat might be the real culprit of SARS virus.

  For thousands of years, as the oldest enemy of human beings, viruses have been coexisting with human beings. Viruses are always threatening human beings, and human beings are constantly developing medicine to conquer viruses. Nowadays, plague has become less attractive, mainly due to the advent of plague vaccine in 1908 and the development of modern biomedicine. However, new viruses are still emerging one after another, and some old viruses are also making a comeback in a mutated way. We have to be on our guard at all times.

  Pandora’s Box was opened.

  The deadly virus or bacteria infected by human beings are actually permanent residents of other species. For example, bats carry a variety of viruses, including hundreds of coronaviruses; Wild snakes carry a variety of parasites in the body. If humans are infected, they can cause peritonitis, septicemia, pericarditis, iriditis and other diseases. In severe cases, they will damage many organs and even endanger their lives. Raccoon is the natural host of rabies virus, and many parasites carried in it can cause damage to human intestines and stomach. The wild groundhog, which became popular on the Internet because of the "expression pack", also carries Yersinia pestis and other germs that can cause intestinal, liver and brain damage.

  Generally speaking, without human intervention, these viruses or bacteria only exist in wild animals. One of the unique qualities of bats is that they are more tolerant of viruses than other mammals. As the only mammal that can fly, bats have a special immune system. In this regard, there is a popular expression on the Internet: "Bats have a high fever of 40 degrees for a long time, and they have sealed the virus for thousands of years by themselves, staying up all night and trying to play a lonely Pandora’s box, so that the virus can coexist peacefully with itself."

  However, as human beings at the top of the biological chain, they sometimes do the opposite, attacking and hunting wild animals for their own selfish desires, and causing many innocent creatures to suffer.

  In some people’s eyes, bats, mice, snakes, pangolins, monkeys and other wild animals are all edible and delicious. Wild animals such as Chinese sturgeon, civet cats and pangolins are on the verge of extinction in many areas due to human overfishing and eating. The populations of giant salamander (giant salamander), wild sea cucumber, wild frogs, wild birds, muntjac, musk deer, gecko and other species have declined sharply.

  Human’s aggression against animals is not only manifested as appetite. In the documentary "The Secret of the Billionaire’s Wardrobe", there is a pair of shoes, only ten pairs are sold worldwide, and the valuation is 20,000 US dollars. The special feature of this pair of shoes is that they are made from the skins of nine kinds of animals, except ostrich skin, crocodile skin, snake skin, and even lizard skin and elephant skin. Luxury brand Hermes has a white platinum bag of Himalayan crocodile, and its flawless leather is actually peeled off from the crocodile.

  In addition, in the process of rapid industrialization and urbanization, forests are cut down, wetlands are squeezed out, and the habitats of wild animals are artificially occupied and separated … … Human activities increase the probability and speed of viruses or pathogenic bacteria in wild animals spreading to human bodies, especially in cities with high population density, which are more prone to epidemic diseases.

  It can be seen that we humans have crossed the border of peaceful coexistence with wild animals, destroyed the original balance of nature, and opened the Pandora’s Box for the spread of epidemics, so that viruses or pathogenic bacteria that originally lived in a closed loop can invade the human body, and constantly mutate and recombine, weaving new strains of viruses or bacteria with stronger toxicity and tolerance, which will inevitably give human beings a painful lesson.

  不打扰,就是最好的相处方式

  人类和自然界的关系比我们想象的要复杂得多。任何野生动物,无论是濒危的还是常见的,在生态系统中都有独特的功能和定位,其他物种无法取代。因此,要从源头上预防新发传染病,我们能做的,就是不打扰——这也是人类与野生动物相处的最好方式。

  不打扰的前提,是我们必须学会敬畏自然。中华文明历来强调“天人合一”的自然观,道家崇尚“道法自然”“清静无为”,孔子提倡“钓而不网,弋不射宿”。如今,我国的经济社会发展进入到一个全新的历史阶段,随着习近平生态文明思想的形成、发展与成功实践,我们必须承认自然的主体价值,敬畏自然,敬畏生命。

  不打扰的内涵,是我们必须学会和谐共生。杜绝不合理的野生动物消费只是最基本的要求,同时还要减少、杜绝对野生动物栖息地的侵扰。在很多人看来,山里没有了野生动物,山还是原来的山。而从生态学的角度看,没有了野生动物,山已经不是原来的山了。一些野生动物的相继灭绝,意味着地球生态系统被破坏,随后,各种自然灾害就会接踵而来。

  The principle of not disturbing is to keep a scientific and reasonable distance. Just when novel coronavirus was raging, wildlife management stations in some places drove away wintering bats on a large scale; In some places, the dogs in the whole village have been killed, and the number of stray cats and dogs in the city has increased in an instant … … It is our human fault to simply and rudely transfer the blame to other animals. From a painful experience, we should think deeply: what kind of distance should we keep between human beings and wild animals? Wild animals grow freely in their own territory. If it is not human intrusion, how can viruses or pathogenic bacteria invade and endanger human health and even life?

  The root of not disturbing is to establish a correct value concept. With the continuous expansion of human greed and the increasing ability to capture nature, when what is claimed exceeds the output of nature, the ecological balance will be broken and human beings will face the crisis of losing their survival safety. The rapid development of industrial civilization for hundreds of years has degraded the earth’s biosphere to the brink of collapse. We must establish correct values, take the idea of ecological civilization as the guide, accelerate the formation of green production methods and lifestyles, consciously protect wild animals, maintain ecological balance, and realize friendly symbiosis and harmonious coexistence between human beings and wild animals.

Students who implement running App in a university in Wuhan can pass only after running for 30 times.

  Zhongxin. com, Wuhan, November 2 (Wang Youzhe, Lin Xinyi, Fu Chengcheng) Recently, Hubei University of Economics launched a running App among freshmen to juniors. According to the regulations, students who have run for 30 times will pass. For each additional time, the effective score will be added with 3 points until 100 points. If the substitute runner is found, it will be treated as cheating and the file will be recorded.

  Cui Gaoyuan, vice president of the School’s Sports school of economics and management, said that the scores of freshmen and sophomores using App for running and punching cards accounted for 30% of this semester’s sports scores, and juniors can only participate in the physical fitness test if their scores using App for running and punching cards reach the standard of passing or above. Students have at most one exercise record every day, which is related to sports achievements, and the excess part is only recorded but not related to achievements.

  Cui Gaoyuan said that the purpose of linking the punch card score with the final sports score is to encourage students to get out of the dormitory, strengthen exercise, cultivate students’ healthy concept of loving sports and advocating sports, form good exercise habits and improve their physical fitness.

  "I used to exercise very little. Since the school implemented the running APP, everyone is running and unconsciously wants to run two steps." Huang Ziwei, a freshman at the school, said that he insisted on punching cards every day and his running enthusiasm was much stronger than before.

  It is worth noting that the school has also formulated an effective standard for single exercise. Boys should run for 1 km at a time, and the running pace should be within the range of 3-9min/km. If a girl’s running mileage reaches 0.8 km at a time and her running pace is within the range of 3-9min/km, her performance will be effective. Cui Gaoyuan said that the introduction of this regulation is mainly to ensure the safety of students, and secondly to achieve sports effects.

  Huang Siqi, a sophomore in the school of finance, said that under this sports standard, you can complete punching as long as you walk faster. However, she also said that this punching APP has a task nature and may affect the quality of sports.

  In this regard, Cui Plateau said that in the background, every time the APP is used to run and punch in, it is set to "random allocation", in order to reduce or even avoid the phenomenon of running on behalf of others. In addition, the school will also conduct supervision through inspection teams, student reports, and big data comparison analysis. If students are found to have "violation of discipline" such as running on behalf of others, once verified, they will be dealt with as cheating in the exam and recorded. (End)

From January to New Year’s Eve, what about our festivals and oral folklore?

Cover journalist Li Yuxin
"The sound of firecrackers is one year old, and the spring breeze warms Tu Su." When I heard that this poem began to appear frequently, it goes without saying that the pace of the Lunar New Year is not far away. Looking forward to it for a year, the Spring Festival, which belongs to the most grand traditional festival of China people, is just around the corner.
In the old days, there was a proverb in Chengdu, which was called "carrots are sweet and sweet, and it is necessary to celebrate the New Year when you see them." In fact, for the old Chengdu people, the "New Year" clock has already rung when they enter the twelfth lunar month, that is, the twelfth lunar month. For more than a month before and after the Spring Festival, ordinary people spent it in an atmosphere full of rich flavor of the year and lively joy. From the Laba Festival on the eighth day of the twelfth lunar month, to the "small year" on the 23rd of the twelfth lunar month, and then to the 24th of the twelfth lunar month, "it took Chengdu people more than a month to finish the New Year, and the content of the Spring Festival was very rich." In the description of folklore expert Liu Xiaochang, the joyful and lively flavor of the year seems to reverberate through time and space.
Folk expert Liu Xiaochang
Don’t blame strict and strict, spring and winter pay in the first month.
Slight cold January 5 (the third day of the twelfth lunar month)
Slight cold, the penultimate solar term among the 24 solar terms, is also the fifth solar term in winter. According to "twenty-four solar term", "On the December Festival, the cold at the beginning of the month is still small, so the clouds are big." It shows that slight cold means cold air accumulated for a long time, which means that the weather is cold but not yet extreme. Like great cold, slight summer heat, great summer heat and summer heat, it is a solar term indicating the change of temperature.
The arrival of the slight cold solar terms also means that the coldest time of the year has arrived. According to Liu Xiaochang, as far as Chengdu is concerned, the temperature in the mild cold season is actually lower than that in the severe cold season. "Therefore, there is a saying that a slight cold is better than a great cold. However, whether it is cold or not in the slight cold season in Chengdu does not depend on the solar terms. What is important is to see whether the cold air is strong. "
In this season, walking in the streets and lanes of Chengdu, I suddenly smell a touch of dark fragrance. Don’t doubt that this is the wintersweet that is proudly open and fragrant in the cold winter. "In the slight cold season, Chengdu can be described as a fragrant city." At this time, flower farmers from Gaodianzi in the eastern suburbs, Flower Zhaobi and Baihuatan in the western suburbs, Phoenix Mountain in the northern suburbs and other places, carrying flower baskets and pushing floats, peddling wintersweet along the street …
"For thousands of years, Chengdu people have loved plum blossoms." Liu Xiaochang said that during the Southern Song Dynasty, the poet Lu You lived in Chengdu and wrote a poem "Plum Blossom Jueju", in which he wrote, "When I traveled to the west of Jincheng City, I was drunk for plum blossoms. Twenty miles of incense, Qingyang Palace to Huanhuaxi ". It can be seen that at that time, Chengdu people loved plum blossoms.
The wind and the meaning of the twelfth lunar month have been in spring, and when it is scattered, it has passed my neighbor.
January 10th of Laba Festival (the eighth day of the twelfth lunar month)
Labazhou (Tuyuan Network)
When it comes to Laba Festival, the first thing that comes to mind is naturally the warm and delicious Laba porridge that night. In Liu Xiaochang’s description, the "New Year" of Chengdu people in the old days began from Laba Festival, which is the eighth day of the twelfth lunar month. "In the old days, on the day of Laba Festival, every household in Chengdu cooked Laba porridge, sacrificed ancestors and had family reunion. Everyone in the family eats a bowl of Laba porridge and presents it to relatives and friends to celebrate the family in this form. "
Laba porridge, also known as "seven treasures and five flavors porridge", "Buddha porridge" and "everyone’s rice", is a kind of porridge made of various ingredients. As early as the Song Dynasty, there were written records about Laba porridge. In the Southern Song Dynasty, Wu Zimu’s "Meng Liang Lu" contained: "On the eighth day of this month, the temple was called Laba. Temples such as Dasha have five-flavor porridge called Laba porridge. " Therefore, the history of drinking Laba porridge has been thousands of years.
Liu Xiaochang said that the ingredients of Laba porridge are exquisite. The ingredients for cooking Laba porridge are mostly cereals such as rice, glutinous rice, coix seed and millet, as well as beans such as red beans, soybeans, rice beans, mung beans and kidney beans, or cooked with dried fruits such as red dates, peanuts, coix seed, lotus seeds, chestnuts, walnuts, longan, ginkgo and almonds. "This pot of porridge is very rich in ingredients. In fact, there are far more than eight kinds. How to cook it depends mainly on the family’s family scenery and the income."
The old snow has not disappeared yet, and the new snow has a family.
January 20th of the Great Cold (the 18th day of the twelfth lunar month)
As the folk saying goes, "A slight cold and a great cold, there is no wind and it is cold" and "A slight cold and a great cold, and it is cold in a ball". It can be seen that in the severe cold season, the weather has been extremely cold. Because of the severe cold solar terms, it is generally in the period of "March 9th".
In ancient times, there was no accurate weather forecast, and people passed it on from mouth to mouth, and invented a folk method to calculate the dates of cold days and warm flowers in spring, called "Counting Nine". According to the folk algorithm, the number nine is counted from the date of the 24 solar terms "Winter Solstice", and every nine days is counted as a "nine", and so on. Generally speaking, "March 9th" is the coldest time in a year. There is a saying that "3949, pigs and dogs freeze to death". When you count to nine "nine days", that is, when you count to 9981 days, it will be deep in spring and warm in the day.
The Great Cold is the last of the 24 solar terms. After the severe cold, it will be beginning of spring, and people will usher in the solar cycle of the new year. Because the New Year’s Day is just around beginning of spring, the new year’s flavor is getting stronger when the cold comes. As a result, the customs of the great cold solar terms are mostly related to the Lunar New Year. People "sweep the dust" and "paste the windows", get rid of old cloth and new ones, clean up and wait for the arrival of the new year. At the same time, we should also "go to the market" to buy La Worship supplies and buy new year’s goods.
In addition to the spring thunder in the dark, the snow is not over yet.
Off-year January 2526 (Lunar December 23-24)
As soon as the new year arrives, people are busy sweeping dust and offering sacrifices to stoves. Off-year has always been regarded as the beginning of a "busy year". Due to the different customs in the north and south, the days called "off-year" are different, usually on the 23rd or 24th of the twelfth lunar month. "On the 23rd of the twelfth lunar month, Chengdu people shouted off-year, and on this night, Master Kitchen God was sent to heaven. Every household in Chengdu has to offer sacrifices to the kitchen stove, that is, to the kitchen god. " Liu Xiaochang said.
Yao Wenhan in Qing Dynasty’s Celebration of the New Year’s Eve
Folk sacrificial stoves originated from the ancient custom of worshipping fire. The kitchen god’s duty is to take charge of the kitchen fire and manage the diet. Later, it was expanded to investigate the good and evil in the world, so as to reduce good and evil. The Ci of Sacrificing a Kitchen by Fan Chengda in the Song Dynasty: "According to the ancient legend, on the 24th day of the twelfth lunar month, the kitchen ruler spoke to the sky … and sent you to the Tianmen to get drunk. Don’t go back to the clouds, begging for profit from the market."
"According to folklore, the kitchen god of every household in the past was sent to earth by the Jade Emperor to protect and observe the good and evil of this family. Seeing how many good deeds and evil deeds this family has done in this year, Kitchen God should remember them one by one. On the night of the twenty-third day of the twelfth lunar month, the Kitchen God will go to heaven and tell the Jade Emperor what this family has done in the past year, so as to bring misfortune and happiness. " Liu Xiaochang said, therefore, it is especially necessary to be cautious on this day, especially to warn your own dolls not to swear, so as not to be unclear.
The roar of firecrackers, the old one year has passed; The warm spring breeze came to the new year, and people drank happily the newly brewed tu su wine.
January 31st, New Year’s Eve (29th day of the twelfth lunar month)
When New Year’s Eve arrives, it means that the old year is over and the new year is replaced. Because New Year’s Eve often falls on the 29th or 30th day of the twelfth lunar month, it is also called New Year’s Eve. But this year’s New Year’s Eve, not on New Year’s Eve. As early as more than ten days ago, the topic # Spring Festival in 2022 has no 30th anniversary # on the hot search. According to astronomical experts, this is mainly related to the "Shuowangyue". The change of the moon is called a Shuowangyue once a week, with an average period of 29.5 days. It happens that the twelfth lunar month is a small moon in 2022, so there is no 30. But experts say that as long as the first day of the first month is still there, the night before is New Year’s Eve.
Qing Leng Mei’s "Spring Scene"
On New Year’s Eve, the most important thing for China families is the reunion dinner. For the old Chengdu people, it is no exception. "In fact, since the twelfth lunar month, every household in Chengdu has begun to prepare. Even people who have no money should try their best to cut a few kilograms of fresh meat and make some bacon to hang on the stove. Some people are very capable, making their own cakes, steaming rice cakes and making candy. " Liu Xiaochang described it.
"A meal to send the old age, spicy fresh food miscellaneous a few feast. Happy to be in the sky, a family size and reunion. " In the past, there was a Zhuzhi poem written in Chengdu, which is a true portrayal of the Chengdu People’s League Year. Of course, besides the reunion dinner, there are many traditional customs on New Year’s Eve, such as offering sacrifices to ancestors, putting up Spring Festival couplets, hanging New Year pictures in stick grilles, guarding the old age, and giving lucky money … The heads of families sit around a table and watch the children happily receive the red envelopes. The New Year’s Eve on the table is full of red couplets and window grilles. For Chinese people, a year’s hard work should be for the reunion and warmth of this moment.

Why did China and the United States win the first mixed doubles in the World Table Tennis Championships?

China news agency, Beijing, November 30 th: Why did China and the United States win the first mixed doubles in the World Table Tennis Championships?
Author Xu Huangguan
On November 29th, Beijing time, a Chinese-American mixed doubles team won the bronze medal at the World Table Tennis Championships held in Houston, USA. It coincides with the 50th anniversary of "Ping-Pong Diplomacy" between China and the United States, and the first group of mixed doubles between China and the United States has attracted people’s attention.

Table tennis is China’s "national sport", which was popularized in mainland China in 1950s. In 1959, after Rong Guotuan won the gold medal at the World Table Tennis Championships in Dortmund, table tennis, which bears the pride and glory of China people, became more and more popular. The "ping-pong diplomacy" that followed was even more popular.

In April, 1971, China’s Zhuang Zedong shook hands with American athlete Cohen. Under the guidance of the political wisdom and diplomatic art of the leaders of the two countries, the small ball turned the big ball and the relationship between big countries broke the ice. After the exchange of visits between Chinese and American players, the upsurge of the two places, the American people holding up signs to write "understanding, friendship and peace", has made many witnesses unforgettable.

The interconnection between the nation and the world. Table tennis originated in the west. At the end of 19th century, tennis was popular in Europe, but due to the limitation of venue and weather, British people began to explore moving tennis indoors. Gradually, the "Table tennis" was born, with the table as the field and the wooden board as the hollow ball. This sport, which is naturally simple and entertaining, is named "Ping-pong" in Chinese because of its crisp and smooth hitting sound.
In March 2006, in order to commemorate the 35th anniversary of China-US ping-pong diplomacy, an American ping-pong delegation visiting China at the invitation of the China Table Tennis Association came to Shanghai to relive the good past with the athletes who participated in China-US ping-pong diplomacy that year.

Later, Ivor Montagu, the "father of table tennis" and the first president of ITTF, injected the connotation of friendship, peace, respect and equality into table tennis. During World War II, table tennis was listed as aid materials of the Red Cross and entered the prison camp. The new World Table Tennis Championships after the war urged the Soviet Union to participate. In 1952, when montague visited China, the ITTF became one of the first international organizations to open its doors to New China, and the World Table Tennis Championships became the first international sports event in the world to hand over the hosting rights to African and Asian cities.

It can be seen that if sports itself has the connotation of pursuing equality and unity, then table tennis is a "special" contained in "universality". Because of its unique origin, character and memory, it is even more condensed with the value of crossing obstacles, creating exchanges, promoting understanding and conveying friendship.
In July, 2011, the China delegation came to the Nixon Presidential Library in California, USA, to commemorate the 40th anniversary of ping-pong diplomacy with American representatives.

This time, it is the first time for the World Table Tennis Championships to come to America. The first group of transnational mixed doubles teams in China and the United States achieved good results, and the American table tennis team won the World Table Tennis Championship medal for the first time in 62 years, which delighted table tennis lovers, sports circles and even people of both countries who supported Sino-US friendship.

The ingenious combination of mixed doubles between China and the United States allows people to relive their historical experience and wisdom, and once again tells the world the significance and achievements of breaking the barrier through table tennis, a highly symbolic sport. It conveys the concept of respect, mutual learning and win-win, and reminds the world that unity is better than confrontation, cooperation is better than differences, and unity is better than isolation.

The "fast fashion" mode causes waste of resources, and the new EU regulations prohibit clothing enterprises from destroying unsold products.

According to a number of foreign media reports from the World Wide Web, in order to crack down on the "fast fashion" mode and reduce the waste of resources, the European Union recently approved new regulations prohibiting large retail enterprises from destroying unsold clothing and footwear.

According to reports, the new regulations not only require enterprises to improve the "durability, reusability, upgradeability and repairability" of their products, but also require garment manufacturers to provide product information through Digital Product Passport. The EU said that enterprises must "take measures to prevent this practice" to make products more durable, facilitate subsequent recycling and reduce resource consumption.

It is reported that the destruction of unsold inventory goods is an open secret of the fashion industry, and the EU hopes to end these unsustainable practices. Alexandra Moreti, a member of the European Parliament, said in a statement: "It is time to end the’ acquisition, manufacturing and disposal’ model, which is very harmful to our planet, our health and our economy." He also said that "banning the destruction of unsold textiles and footwear products will help change the way fast fashion manufacturers produce goods".

Scott Lipinski, CEO of the German Fashion Association and the European Fashion Federation (EFA), said that the EU needs to clarify the meaning of "unsold goods" and "destruction". For the association, unsold goods mean that they are suitable for consumption or sale (excluding fakes and samples). The industry is also firmly committed to opening up new methods, such as remanufacturing and upgrading recycling, which give unsold products a second life and allow creative freedom.

It is reported that the new regulation issued by the European Union will take effect for large enterprises in two years, and medium-sized enterprises can be exempted from the regulation for six years, while smaller enterprises (less than 50 employees) can be exempted. Some data show that the influence of textile consumption on climate change is second only to food, housing and transportation.
