This is the first photo of the black hole at the center of the Milky Way released by astronomers on May 12. Xinhua News Agency

At 21:00 on May 12, Beijing time, the Event Horizon Telescope (EHT) cooperation organization held a press conference in seven cities around the world, including Shanghai, and announced the first photo of the supermassive black hole (Sagittarius A *) at the center of the Milky Way. For the first time in human history, the true face of the center of the Milky Way has been revealed.

This black hole photo was co-organized by the Event Horizon Telescope (EHT) and "taken" through a network of radio telescopes distributed around the world. Its release gives evidence that Sagittarius A * is the black hole in the center of the Milky Way, providing valuable clues for understanding this "behemoth" that is generally believed to inhabit the center of most galaxies. Its birth opened a new chapter in human exploration of the black hole in the center of the Milky Way.

Getting to know black holes for the first time

For the mysterious and vast universe, human beings are always full of imagination, and most of them come from the most primitive curiosity of human beings. With the development of science and technology, many imaginings have become scientific predictions, and through the unremitting exploration of generations of scientists, they have further become reality.

Modern astronomy tells us that the beautiful Milky Way we see at night is actually a flat disk-shaped spiral galaxy composed of hundreds of billions of stars. And our solar system, as an ordinary member of it, revolves around the center of the Milky Way 27,000 light-years away from the center of the Milky Way.

The "Galactic Center" was located in the direction of Sagittarius, which was covered with a large amount of gas and dust. It was difficult to observe in the visible light band, and the infrared and radio bands with longer wavelengths were less affected, which became the main way to study the "Galactic Center".

In 1933, when Carl Jansky of Bell Labs published a paper announcing the discovery of radio radiation possibly originating from the center of the Milky Way galaxy, it was the first time that humans had captured radio waves in the depths of space, but scientists at the time knew nothing about the secrets behind this intense radio radiation. Over the next three decades, Jansky’s findings were not only confirmed, but also traces of intense radio radiation were found in other, more distant galaxies.

Similar findings have led theorists to make bold predictions that galaxies harbor supermassive black holes at their centers, which are sources of intense radio radiation.

Black holes are cosmic celestial bodies that make many people curious. But few people really understand this cosmic "monster".

What is a black hole? "In layman’s terms, a black hole is actually the remains of a huge star," said Qin Ruiqiang, president of the Hebei Astronomy Amateur Association.

According to the introduction, the interior of a star is constantly undergoing thermonuclear reactions. When a star ages, it uses up the fuel in the center due to thermonuclear reactions, and there is not much energy produced by the center. At this time, it can no longer bear the huge weight of the shell. Therefore, under the weight of the shell, the core begins to collapse, and matter will inexorably "march" towards the center point. At this time, a supernova explosion will occur for a long time, until finally the star forms a star with a volume close to infinity and an almost infinite density, which is a black hole.

To fly from Earth to space, a rocket needs to reach a speed of 7.9 kilometers per second. As the mass of the Earth continues to increase, its surface attractive force will also increase, and the rocket will escape the Earth at an increasing speed. When this speed reaches 300,000 kilometers per second, nothing can escape the celestial body, including light.

A black hole is this celestial object that even light cannot escape, and this region is known as the black hole’s event horizon.

Inside, no light can escape, and all matter and mass gather at the singularity at the center of the black hole, where the curvature of space-time is infinite and the attractive force is infinite. Once inside the event horizon, all the laws of physics we know about the world break down.

In 1971, astronomers Nader Lindenberg and Martin Rees first predicted that there was a supermassive black hole at the center of the Milky Way. Because of the nature of black holes, it cannot be directly observed. But as the black hole swallows other matter, it forms an accretion disk, in which a large amount of matter rotates, rubs, and warms around the black hole, making the temperature here reach millions of degrees Celsius and appear very bright.

Black holes are one of the rarest cases in the history of science, developed to the point of exhaustion as a mathematical model without any observational evidence to prove their theory correct. In the early 20th century, black holes became widely known by Einstein’s general theory of relativity, but scientists did not discover the first black hole until 1970.

Although scientists have long simulated the appearance of black holes in supercomputers, they have long hoped to take a picture of them.

Photographing a black hole

With the continuous advancement of technology, humans can finally take pictures of black holes. Scientists chose two supermassive black holes as "models".

Released this year is Sagittarius A *, the supermassive black hole at the center of the Milky Way, 27,000 light-years from Earth and more than 400 times the mass of the Sun. The black hole image released in 2019 is from the galaxy M87, which is farther and larger, 55 million light-years away from Earth and 6.50 billion times the mass of the Sun.

"People observe these two black holes from the earth, they are very small, and the apparent diameter of the ring structure is only about 40 to 50 microarc seconds." Qin Ruiqiang introduced that a microarc second is about the size of the period at the end of an article on the earth when viewed from the moon. The two black holes seem to be a "doughnut" on the surface of the moon 380,000 kilometers away from the ground.

Such a small apparent diameter challenges the angular resolution of telescopes.

"Angular resolution is a term that describes the capabilities of a telescope," Mr. Qin said. The smaller the angular resolution, the better the telescope’s ability to distinguish distant celestial bodies, and the clearer the images we can obtain.

The optical telescope is affected by the lens process and the earth’s atmosphere, and its resolution is weak. Even the 39.3-meter European Extremely Large Telescope under construction has a theoretical limit angular resolution of only 1,000 microarcseconds, which is still far from 50 microarcseconds.

Therefore, scientists thought of radio telescopes.

The aperture of a single radio telescope can reach tens of meters or even hundreds of meters. Although the resolution is much lower than that of optical telescopes of the same aperture due to its longer observation wavelength, scientists can use a VLBI (Very Long Baseline Interferometry) technology to form two or more radio telescopes into a larger aperture radio telescope, and improve the resolution by increasing the aperture.

According to reports, the black hole photos released in 2019 were also contributed by the Shanghai Tianma Telescope. It formed the East Asia VLBI Network with several stations in South Korea and Japan to conduct observations. The addition of the Tianma Telescope has improved the quality of East Asia VLBI maps by 53%.

Although Sagittarius A * is closer to Earth, photographing it is much more difficult than M87 *. The achievement was achieved by the whims of more than 300 researchers from 80 research institutions around the world.

The EHT collaboration "combined" eight radio telescopes in six geographic locations around the world to form a so-called "Event Horizon Telescope" with unprecedented sensitivity and resolution.

In 2017, the eight telescopes, which travel north to Spain and south to the South Pole, cast a "big net" at selected targets to "retrieve" massive amounts of data to give us a picture of what a black hole looks like. But the observation window left to scientists is very short, only about 10 days per year.

In addition to the limitation of observation time, photographing black holes is also extremely demanding in terms of weather conditions. "Water in the atmosphere has a significant impact on this observation band, and water affects the intensity of radio waves, which means that precipitation can interfere with observations." As a result, experts say, the eight telescopes are located in areas with high altitudes, very little rainfall and a very high probability of sunny days.

In addition, successful imaging requires all telescopes to be fully synchronized in time. During observations, each radio telescope collects and records radio wave signals from the vicinity of the target black hole, which are integrated to obtain an image of the event horizon. To ensure signal stability, the EHT uses atomic clocks to ensure that the signals it collects and records are synchronized in time.

Chi-kwan Chan, a scientist at the Steward Observatory in the United States, the Department of Astronomy and the Institute of Data Science at the University of Arizona, has described the difficulty of observing Sagittarius A * this way: "The surrounding gas is rotating around Sagittarius A * and M87 * at a high speed at almost the speed of light. It takes a few days to several weeks for the gas to circle M87 *, but for the much smaller Sagittarius A *, the gas can circle once in a few minutes. This means that as the EHT observes Sagittarius A *, the brightness and pattern of the gas surrounding the supermassive black hole are also changing rapidly over time. Taking a picture of Sagittarius A * is a bit like taking a clear picture of a puppy chasing its tail."

In the future, EHT will make a black hole "movie"

Using existing images of two black holes with masses more than 1,500 times different, scientists can further examine the attractive forces in extreme environments.

The photo of Sagittarius A * was made from a combination of many photos extracted from the EHT observation data in 2017. Since then, in 2018, 2020 and 2021, the EHT cooperation organization has not stopped the pace of observation research. Moreover, the number of EHT stations continues to increase. In 2018, three new stations were added, including the Greenland Telescope, and the coverage of the observation array was further expanded.

In future plans, more telescopes will be used to expand the EHT observation array.

In addition to the increase in the number of telescopes, starting in 2023, the EHT will conduct observations in the 0.87mm band, which will improve the resolution by nearly 50% compared to observations in the 1.3mm band under the same circumstances. Sagittarius A * and M87 * remain the most important scientific targets of the EHT collaboration, and astronomers are exploring how they change over time and studying the surrounding magnetic field.

The continued expansion of the EHT population and technological innovation will allow scientists to share more compelling astronomical photos, and even "movies" of black holes.

"Using the next-generation EHT to film such a’movie ‘of the black hole at the center of the Milky Way is the pursuit of astronomers." Some astronomers said so.

Scientists in our country have long been concerned about high-resolution black hole imaging research. In this EHT cooperation, scientists in our country actively participated in the joint promotion of early EHT international cooperation, the joint application of EHT observation time, the observation operation of the Maxwell Telescope in Hawaii, and the post-data processing and analysis.

Scientists will also aim their telescopes at other sources to make more "doughnuts," experts say, a goal that could be achieved by building space telescopes because other "doughnuts" are smaller. (Wang Ludan, Hebei Daily reporter)

The DM-p model went on the market, and three new models were launched. After comprehensive subsidies, the price was 289,800-329,800 yuan. The biggest highlight is equipped with BYD DM-p hybrid technology. The specific price is as follows:

Next, let’s take a look at how the new car products perform. And what is the actual car cost?

Compared with Tang DM-i, which is also a mixed version, BYD Tang DM-p is mainly different from it in power technology and has been upgraded in design and configuration.

1, equipped with BYD DM-p hybrid technology, 100 km acceleration of 4.3 seconds.

BYD Tang DM-p is equipped with BYD’s DM-p hybrid technology. The core components, Xiaoyun plug-in special 1.5T high-efficiency engine and EHS160 electric hybrid system, have all been fully upgraded. At the same time, the newly developed rear-drive three-in-one assembly has a high degree of system integration and the vehicle power has been greatly improved. Simply put, in terms of dynamic performance, BYD DM-p King Hybrid is stronger than DM-i Super Hybrid.

Specific to the parameters, the comprehensive power of BYD Tang DM-p system reaches 452kW, and the acceleration of 100 kilometers takes only 4.3 seconds. While having strong performance, the fuel consumption of BYD Tang DM-p is only 6.5L/100km. It is not difficult to see that under the empowerment of DM-p hybrid technology, BYD Tang DM-p truly achieves performance and energy saving without contradiction, faster and more economical.

On the basis of excellent power, BYD Tang DM-p is also equipped with super intelligent electric four-wheel drive, DiSus-C intelligent electronically controlled active suspension, and Eaton differential lock, which makes it have excellent handling stability and ability to get out of trouble.

Finally, in terms of battery life, thanks to a 45.8kWh large-capacity battery, BYD Tang DM-p’s NEDC battery life has reached 215km, which can fully cope with the daily pure electric travel in cities. And its comprehensive battery life has reached 1020km.

2. Adopt a brand-new front face design

In terms of appearance, BYD Tang DM-p still continues the Dragon Face 3.0 design language, but different from the DM-i version, BYD Tang DM-p adopts a design style similar to BYD Han DM-p, with more exquisite and fashionable visual perception, and the overall gas field of the vehicle has also been significantly improved.

In other respects, there is not much difference between the new car and the current DM-i version. Including the interior, the new car has not been adjusted much, and we can still easily distinguish that it is a model from BYD brand.

3. Provide six cabins and upgrade the configuration.

In terms of body size, the length, width and height of the new car are 4870/1950/1725mm and the wheelbase is 2820mm respectively, and Tang DM-p provides a brand-new 6-seat version of 2+2+2, which further improves the comfort of the second row compared with the 7-seat version and makes it more convenient to enter the third row.

In other luxury configurations, the new car has also been improved to some extent, such as HiFi-level custom-made Dana audio, intelligent aromatherapy, and two-color matching NAPPA leather seats.

To sum up, Tang DM-p can be regarded as a mixed version of Tang with stronger performance. If you pursue performance and control, you can choose Tang DM-P.. And if you pay more attention to pure battery life and economy, you can also choose.
. Or if you want a large pure electric SUV, then
It is also a good choice.

According to the maintenance manual, BYD Tang DM-p, like Tang DM-i, has the first maintenance time of 3500km or 6 months, in which the first maintenance is free, and the subsequent maintenance interval is 7500km or 12 months. Then, if the total mileage is 600 million kilometers in three years, the total maintenance cost of BYD Tang DM-p is 7366 yuan, and the average annual cost is about 2445 yuan. As a medium and large SUV, the maintenance price of BYD Tang DM-p is in the middle of its class.

In the part of taxes and fees, the compulsory insurance of BYD Tang DM-p is 950 yuan, and the vehicle and vessel use fee is 420 yuan. As for the commercial insurance, we take BYD Tang’s 2022 DM-p 215KM four-wheel drive distinguished model as an example, and its official guide price is 289,800 yuan. We only choose basic insurance such as car damage insurance and 1 million yuan third-party liability insurance, plus three basic insurances excluding deductible to simulate and calculate the insurance amount. The total insurance cost of the new car in the first year is about 9,731 yuan. Plus travel tax and traffic insurance expenses, the total is 11101 yuan. It should be noted that if there is no record of accidents or violations in the first insurance period, the premium for the next year will be discounted to a certain extent. Generally, it is calculated under the condition that it is not out of danger, and it is calculated at 20% discount in the following year and 30% discount in the third year.

As for the annual total expenditure, we calculate the mileage and fuel consumption of 20,000 kilometers per year based on the official fuel consumption of 6.5L/100KM (refer to the recent oil price of No.92 gasoline in Shanghai for 8.23 yuan /L). Of course, if you are diligent in charging, there will be a lower car cost. The calculation method of paying car damage insurance and third party liability insurance for insurance plus excluding deductible. And if there is no accident, the premium will be 20% off in the second year and 30% off in the third year, taking the average of the three-year premium. Together with these conditions, the annual car cost of BYD Tang DM-p is 22,395 yuan, and the average monthly cost is 1,866 yuan, which is basically at the mainstream level of domestic small SUVs. See the following table for details:

It should be noted that the above expenses do not include some extra car expenses such as parking fees, violation fees, car washing fees, high-speed fees and maintenance fees, and these expenses will be different according to individual car use behavior and car use environment, and cannot be generalized. Ok, the above is the product information and approximate car cost of BYD Tang DM-P. So, what do you think of the monthly car cost of 1866? Welcome everyone to leave a comment below!

　　At 12: 12 on January 19th, China Academy of Launch Vehicle Technology, affiliated to China Aerospace Science and Technology Corporation, successfully launched the Long March 11th solid launch vehicle with one arrow and six stars, which was the first time that China’s solid launch vehicle provided launch services to international users.

　　People’s vision

　　Not long ago, American Space Exploration Company’s Falcon heavy rocket was successfully launched for the first time, and a Tesla electric sports car was sent into space. This gimmick has attracted the attention of the public, and the technical characteristics of the Falcon heavy rocket have also caused a heated discussion in the global space industry and pushed commercial space into the public eye.

　　So, what changes will commercial aerospace bring to the human space field? What impact will it have on China Aerospace?

　　During the "Thirteenth Five-Year Plan" period, the total space industry market in China will reach 800 billion yuan.

　　In recent years, China’s commercial space activities have continued, and good news has spread frequently. If 2015 is the first year of China’s commercial aerospace development, then it can be said that commercial aerospace has ushered in spring in 2018.

　　In January this year, the Long March 11 solid launch vehicle was launched for the first time, which means that China’s solid launch vehicle began to provide launch services for international users.

　　Yang Yiqiang, commander-in-chief of the Chang 11 rocket, believes that "the success of the launch mission means that the commercial launch service process and configuration of the Chang 11 rocket will be further improved, which will provide more and better choices for the launch of many commercial satellites."

　　"Commercial aerospace is a market-oriented aerospace activity with a commercial profit model." Zhang Qin, vice president of the Fourth Research Institute of China Aerospace Science and Industry Group, thinks.

　　According to the Aerospace Report released by the American Aerospace Foundation in 2016, the global aerospace economy in 2015 reached 335.3 billion US dollars, of which commercial aerospace accounted for 76%. According to experts’ prediction, by 2020, the global space industry market will reach US$ 485 billion, corresponding to the China market, which will reach 800 billion yuan during the 13th Five-Year Plan period.

　　For this reason, it is becoming a unanimous choice for all countries in the world to find a suitable business operation model and expand and share the valuable "cake" of commercial aerospace.

　　Some private enterprises in China have actively participated in commercial aerospace. In January this year, Beijing Blue Arrow Space Technology Co., Ltd. signed a rocket launch service agreement with Danish enterprises, which is the first commercial rocket launch service order in the international market undertaken by domestic private commercial aerospace enterprises.

　　"The core advantages of private commercial aerospace are rapid decision-making and rapid technical iteration." Zhang Changwu, CEO of Beijing Blue Arrow, said that he will focus on verifying the reliability of technology in the next two years, and introduce a more perfect competition mechanism to reduce costs through wider selection of materials and more open technical cooperation.

　　In addition to commercial launch, in the field of space tourism, private commercial space flight has also made new progress. Beijing Golden Ocean Aerospace Company has previously demonstrated China’s first commercial skydiving suit. According to the developer, the suit has the functions of vacuum protection, thermal protection, communication between heaven and earth, positioning and so on. At present, it has passed the laboratory simulation test and can be used in complex environments such as stratosphere and space.

　　Previously, China Aerospace Science and Technology Rocket Technology Co., Ltd. raised 1.2 billion yuan of social capital in the A round of capital increase, which injected a strong impetus into commercial aerospace and also played a good demonstration role. The investor’s representative lamented: This subverted the previous impression that scientific and technological personnel were "chasing" investors with projects, and fully reflected the charm of "hard technology" innovation.

　　Up to now, China has successfully launched dozens of commercial satellites. In 2018, China will also make efforts in many fields of commercial aerospace. Yin Liming, president of Great Wall Company, a subsidiary of China Aerospace Science and Technology Corporation, said that in 2018, Great Wall Company will ensure the completion of domestic commercial launch missions such as Hongyan’s first star, No.1 01 star and global change scientific experimental satellite.

　　"Commercial aerospace, as a new format with strong technological innovation, high economic quality and efficiency and both military and civilian attributes, is an important carrier for implementing the national integration of defense and civilian technologies strategy and maintaining and increasing the value of state-owned assets, and is an extremely important and new growth pole for China’s economic development. Under the background of economic and technological globalization, highly developed commercial aerospace is one of the important symbols of world-class aerospace companies and aerospace powers. " Yang Baohua, deputy general manager of China Aerospace Science and Technology Corporation, believes.

　　According to industry estimates, for every dollar invested in the commercial aerospace field, it can boost investment of 7 to 14 dollars.

　　The commercial aerospace model can meet the needs of customers with low cost, high efficiency and high reliability.

　　"The commercial aerospace model can meet the needs of customers with low cost, high efficiency and high reliability, which has an important role in promoting the rapid development of space tourism and even the entire space technology." Pang Zhihao, executive editor of International Space magazine, said.

　　Liu Shiquan, deputy general manager of China Aerospace Science and Industry Group Co., Ltd., introduced the Falcon — The 9 "rocket has lowered the price of commercial launch by an order of magnitude. The same falcon — 9 "rocket, developed by NASA, costs at least $1.3 billion, while commercial companies only spend less than $400 million.

　　While the cost is reduced, the efficiency is also obviously improved. Liu Shiquan said that the first is to shorten the development cycle, "Falcon — 9 "It took only four and a half years from design to first flight; Secondly, the acceleration of technological innovation, "Falcon — 9 "A series of reusable rocket tests were carried out, and both land and offshore platform recovery tests were successful. "Commercial aerospace management institutions have implemented flat management, which has greatly shortened the management chain."

　　Liang Jiqiu, chief designer of Kuaizhou rocket of China Aerospace Science and Technology Rocket Technology Co., Ltd., said that in international commercial launch, the asking price of a rocket carrying a kilogram load is 25,000 to 30,000 US dollars, while the price of Kuaizhou 11 per kilogram load is only 10,000 US dollars. Through scientific and technological innovation, the take-off quality of Kuaizhou series rockets is reduced by about 20 tons compared with similar products, and this alone can directly reduce the launch cost by more than 10 million yuan. This makes this series of rockets truly a "commodity", not just a "product".

　　Commercial rockets with high cost performance will become "space vehicles", making it possible for ordinary people to travel in space.

　　As an ordinary person, what services can you enjoy in commercial aerospace?

　　Dr. Zhang Baoqing from Beijing Institute of Aerospace Information and Information believes that navigation satellites are obviously the closest service to consumers. In China, Beidou satellite navigation system attaches great importance to the consumer market, and Beidou navigation service has been applied to quite a few types of mobile phones. The industry believes that Beidou will achieve the annual output value target of 400 billion yuan in 2020.

　　High-resolution Earth observation constellation can be used to detect the changes of oil and coal production, transportation and storage, monitor the operation of large power plants, and provide objective and accurate decision-making reference data for energy enterprises.

　　Zhang Yong believes that cost-effective commercial rockets will become "space vehicles", opening the door to space travel for everyone, and ordinary people may also have a chance to travel in space.

　　"So far, China’s aerospace data application industry chain has not yet formed, and the depth of space resource value mining is not enough." In the view of Li Jinxiang, deputy chief engineer of China Electronics Technology Group, China’s commercial aerospace can do better. "At present, the commercial distribution, sales and data classification standards of aerospace data are not clear, which makes aerospace data scattered in various departments, resources are difficult to share, and applications are in a fragmented state."

　　Li Jinxiang suggested that relevant national policies and regulations on the commercial application of national commercial aerospace data should be promulgated as soon as possible, military and civilian aerospace resources should be developed as a whole, and a national-level aerospace data application service system should be established, so that the aerospace industry can explore a business operation mode that is closer to the people, serves life and is profitable.

　　Relevant experts also agree to speed up the legislation of commercial aerospace, break the shackles of commercial aerospace development through legal system innovation and governance mechanism reform, and ensure that different market players are equally protected by law.

　　Yang Tianliang, a researcher at Sanya Research Center, Institute of Remote Sensing Earth, Chinese Academy of Sciences, believes that the development ideas and specific paths of commercial aerospace must be considered in the context of integration of defense and civilian technologies’s development. We should not only change our concepts and realize that space technology and industry can serve both national defense and people’s livelihood, but also formulate policies and measures to promote the development of commercial space and support the development of private space enterprises.

　　Entrusted the owner of the lottery shop to buy lottery tickets on his behalf, but he won 14 million prizes. But when I wanted to get the lottery ticket, I found that the boss couldn’t contact me, and even the lottery shop was closed. Upon further inquiry, the winning lottery ticket went to the boss’s friend.

　　The boss took the lottery and ran away? Or do you want to swallow the grand prize? Who finally won the 14 million prize?

　　Yesterday, a reporter from qianjiang evening news came to this small lottery shop in Shengzhou. On November 10th, five days after closing, the lottery shop reopened. After this big prize storm, Xiao Xu, the post-90 s boss, was a little tired. He said, "If the sports lottery shop stops, I may never know for a lifetime, but I am willing to stand up and deal with this crisis."

　　Won more than 14 million yuan.

　　I can’t get the lottery ticket.

　　Things should start from November 5.

　　Mr. Sun, an old lottery player in Shengzhou, followed a group of lottery tickets for a long time, spending 218 yuan a week to follow 109 lottery tickets. Sometimes he doesn’t have time, he will entrust a nearby sports lottery station to buy it. On November 5, Mr. Sun WeChat entrusted Xiao Xu to buy tickets. Xiao Xu is 23 years old. He has just opened this sports lottery station for two months.

　　On the night of the Super Lotto, two of the lottery numbers purchased by Mr. Sun won the first prize, and the bonus for each note was 7114758 yuan. In this way, Mr. Sun won more than 14 million yuan.

　　Mr. Sun was so excited that he called Xiao Xu immediately. Xiao Xu also confirmed that Mr. Sun won the lottery. Who knows that after this call, Xiao Xu can’t contact and the store is closed.

　　Seeing that the prize is about to be redeemed, but the lottery ticket is not available, Mr. Sun is anxious.

　　There is only one lottery ticket.

　　There are two winners.

　　The lottery ticket that won the grand prize is in the hand of Mr. Ying, a friend of Xiao Xu. What’s going on?

　　The following is Xiao Xu’s self-report:

　　On the morning of November 3rd, Mr. Ying came to my shop. He only bought scratch music before, and this time he asked me how to buy the lotto. I recommend him to buy a set of numbers that Mr. Sun often calls. In the evening, we watched TV together. On November 4th, at about two o’clock in the morning, he gave me 220 yuan to buy lottery tickets. But the lottery machine was off at that time, so I told him to help him type out the lottery ticket the next day. Unfortunately, I forgot later.

　　On November 5, I asked Mr. Sun on WeChat as before if he wanted to type out the lottery ticket he had been following. Mr. Sun said yes, so I typed the ticket for him.

　　After the lottery that night, Mr. Sun called me, and I was very excited. But this time I remembered that I only had one set of lottery tickets.

　　I’m a little flustered, because it’s more than 10 million yuan after all, and we ordinary people can’t earn so much money in our lifetime.

　　Who will win the lottery? Mr. Ying told Xiao Xu that he had called and paid the money on the spot, so the lottery ticket belonged to him. So, Xiao Xu handed the lottery ticket to Mr. Ying that night.

　　Who should the lottery go to?

　　Shopkeepers, they asked seven lawyers.

　　Xiao Xu said that he later found that there were more than 20 people around the door of the store, and he panicked, so he turned off his mobile phone and the store was closed.

　　Here, Mr. Sun, who was in a hurry to get angry, consulted a lawyer, and the lawyer suggested applying to the court for property preservation.

　　On November 7, when Mr. Ying took the lottery ticket to win the prize, he found that it had been frozen.

　　For the ownership of the grand prize, the two began to negotiate.

　　Xiao Xu also clarified to us that he has been negotiating with two lottery buyers and has not run away. "When people see me close the door, they must think I’m looking for ‘ Tuo ’ Stealing the grand prize, or I ran away with the lottery ticket. In fact, the next day, I contacted Mr. Sun with my mother’s number and told the story, which was evidenced by the call record. "

　　Xiao Xu said that for this matter, he and Mr. Ying consulted different lawyers seven times. "Shengzhou consulted four and Hangzhou asked three."

　　Xiao Xu is concerned about whether he is responsible for this matter. What Mr. Ying asked is whether he can win the grand prize.

　　Lawyer: Let’s see whose evidence is reliable.

　　Who should win the grand prize? Let’s listen to the lawyer.

　　Lawyer Chen Yilai of Zhejiang Times Commercial Law Firm analyzed: Mr. Sun entrusted Xiao Xu to buy lottery tickets through WeChat, and the entrustment relationship was still established whether he paid or not. If Mr. Sun can’t get the lottery ticket, he can file a lawsuit, and the WeChat message between him and Xiao Xu can be used as electronic evidence.

　　What about Mr. Ying? According to Xiao Xu, Mr. Ying paid in cash at that time, accompanied by Mr. Ying’s wife and a friend, and there was no other physical evidence. The lawyer explained that the key evidence identification mainly lies in documentary evidence, and witness testimony has only an auxiliary role, while the effectiveness of interested witness testimony needs to be verified.

　　If Mr. Ying wants to get back the lottery prize, he can sue Xiao Xu and ask the other party to compensate according to the amount of the winning lottery ticket. This is a typical contract breach lawsuit. But effective and sufficient evidence must be provided.

　　Outcome: Who will get 14 million yuan?

　　On November 9th, the lawyers of Mr. Ying and Mr. Sun negotiated, and the lottery ticket went to Mr. Sun. After that, the lottery ticket was successfully redeemed and the sports lottery station reopened on the same day.

　　Mr. Ying, who passed the grand prize, said that his mood these days is like riding a roller coaster, going back and forth from the peak to the bottom countless times. However, he and Xiao Xu have been friends for many years. If they cut off contact for lottery tickets, it would not be worth the loss, so they have no intention to sue Xiao Xu.

#270,000 elderly golden cases open##

The truth of this fact is that from 2009 to 2015, the old lady of Shanghai, Qian Mou, would abandon the husband who lost his ability to take care of his self -care in the hospital after paying some medical expenses during the hospitalization treatment, until the husband died alone. After the death of her husband, Qian still refused to go through the relevant procedures, and at the same time, he took the husband’s pension and accounted for himself.

On June 9, 2021, a case of fraud and abandonment of Qian, a public prosecution of the People’s Procuratorate of Minhang District, Shanghai, was held in the Minhang District People’s Court.

The truth of the case is very clear.

Some people think that pensions are in the country, and the national Tang monk meat, all Chinese citizens can eat, all of which are desirable. Therefore, it is not believed that the old lady of Shanghai Qian Mou is a criminal act. This view is particularly popular in the small and fresh meat little beauties. Because the little fresh meat and the little beauty thinks that farmers are reasonable to eat white food, everyone can not pay a penny social security, and they can be sits to share the social security provers for decades.

However, the understanding of farmers is extreme errors.

In the basic composition of pensions, all pensions of social insurance forms should belong to the private property of citizens who pay social security, and they are not owned by the whole society. In the basic pension of the national welfare form, [also known as the pension subsidy], that is, the country’s money from the city taxpayer to the farmer, the other social benefits that belong to the country to the farmers to the elderly.

Compared with the former, although it is also called pension, it is actually very different in nature. That is to say, the essence of social maintenance money is the private property of citizens who pay social security. They use their labor income to take out a part of their salary every month to invest in their future pensions, like bank savings. But more advanced than banks, these social property from citizens is managed by the state and has absolute security and insurance stability. The basic pension [also known as the pension subsidy for white hair to the farmers], the source of funds is not the citizen of the social security, but from the city’s hundreds of millions of taxpayers. Do not bear the tax responsibilities and obligations that every citizen should have, and the one billion farmers have no longer contributed a penny to the national fiscal tax for seventeen years. Therefore, these money -sweats from urban taxpayers have been distributed to farmers through the hands of the country. The money does not have the nature of private property, but has a social welfare nature.

Understanding the above principles, I understand that the old lady of Shanghai, Qian Mou, led her died of more than 270,000 yuan. The violent object was the private property of all social security citizens.

Similarly, those who do not pay a penny for social security, and those who have to pay the social security persons for decades of social security people are divided by farmers, which are those who eat white food selfish little fresh meat and little beauty. In fact Criminal behavior, they are public robbery, because their violations are the private property of the whole society who has paid social security for decades. But it is terrible that some people have committed guilty and do not know sin. Zhen Zhen has words that he is the savior of the peasant. He has called for robbery and plundering under the banner of speaking for farmers. As criminals, they have gone far enough on the road of illegal.

These pension articles videos are full of headlines. This fully shows that a large number of cyber criminals are active on the media network. They attempted to learn ancient bandits and live on the wealth of others by robbing others.

The opening of the old lady in Shanghai should let the small and fresh meat and little beauties who advocated robbery to calm the rational and rational girls. Please do not go further and further on the road of crime.
