This week, a mutant strain of COVID-19 called "Delta" sounded a new alert for the global epidemic.

　　According to the Guardian, 99% of the new cases in Britain are infected with the "Delta" strain. WHO pointed out that 92 countries and regions around the world have detected the spread of the "Delta" strain. On June 25th, WHO Director-General Tan Desai was worried.

　　WHO Director-General Tedros Adhanom Ghebreyesus:"Delta" mutant strain is the most transmissible strain found so far, which has appeared in at least 85 countries and regions and is spreading rapidly among unvaccinated people.

　　A few days ago, WHO confirmed that the strain had spread to 92 countries and regions.

　　Swaminatan, chief scientist of WHO:Because the spreading ability of the "Delta" mutant strain has been significantly enhanced, this mutant strain in Covid-19 is becoming the main Covid-19 mutant strain in the world.

　　The "Delta" mutant strain was first discovered in India in October, 2020, and was named B.1.617.2 scientifically.

　　In May this year, in order to avoid the stigma associated with a specific country and facilitate its use, WHO announced the use of Greek letters to name the mutant strains found in various countries.

　　The four mutant strains listed as "needing attention" by WHO have new names corresponding to the first four letters of the Greek alphabet: alpha, beta, gamma and delta.

　　Among them, alpha, beta and gamma mutant strains all have a mutation called "N501Y", which seems to strengthen the infectivity of the virus to cells and make the virus spread more easily.

　　Beta and gamma mutant strains also have a key mutation, called "E484K", which may enable the virus to avoid being blocked by the immune system.

　　The mutation of "Delta" mutant strain is different. Initially, "Delta" was considered as a "double mutant" virus.

　　Maria Van Kokhov, Technical Director of WHO Health Emergency Project:First discovered and reported by India, there are two mutations, E484Q and L452R.

　　Djamil, dean of Trivedi School of Biological Sciences, Asoka University, pointed out in an exclusive interview with Xilong Times that the statement of "double mutation" is not accurate. The Delta variety contains 15 mutations in total, 6 of which occur in spike protein, and 3 of them are key: L452R, E484Q and P681R.

　　L452R improves the ability of virus to invade cells, E484Q helps to enhance the immune escape of virus, and P681R can also make virus enter cells more effectively.

　　The combined effect of these mutations makes the "Delta" mutant strain partially avoid some neutralizing antibodies, so it is more infectious.

　　Maria Van Kokhov, Technical Director of WHO Health Emergency Project:We know that the "Delta" variant does increase the spread, which means that it can be more easily spread among people. This is related to known mutations, which allow viruses to adhere to cells and invade cells more easily.

　　The BBC synthesized data from Imperial College London and The Lancet magazine, and compared the basic infection number of COVID-19 mutant strain with other viruses, that is, R0.

　　R0 of "Alpha" mutant strain is 4-mdash; 5. That is to say, without any intervention of epidemic prevention measures, a patient infected with "Alpha" mutant strain can continue to transmit the virus to 4— Five people.

　　R0 of Delta mutant strain is 5-mdash; 8；

　　The R0 of mumps is 12;

　　The R0 of measles is 18.

　　A study in The Lancet, an international medical journal, shows that the risk of hospitalization is twice as high for people infected with the "Delta" mutant strain as for people infected with the "Alpha" mutant strain.

　　Hairdressing shop owner Shawang:We used to earn 300,000 to 350,000 rupees a month, but now we are completely losing money, and most hairdressers have returned to their villages.

　　This is Maharashtra, one of India’s major economic and cultural centers.

　　According to the international authoritative journal Nature, in the past few months, the highly contagious "Delta" mutant strain has spread rapidly in India and has become the main strain prevalent in Maharashtra. But the ferocity of "Delta" does not stop there.

　　In March this year, researchers first discovered a further variant of the "Delta+"strain in Europe. In early April, "Delta+"was also detected in Maharashtra.

　　According to a report by India’s New Delhi TV Station on June 23rd, at least 40 cases of "Delta+"infection have been found in seven Indian states including Maharashtra, Kerala and Madhya Pradesh, among which Maharashtra has reported more than 20 cases.

　　Trust card for director of hospital intensive care unit:A large number of vulnerable people live in rural areas, suburbs and small towns. This time we expect the virus to spread to these areas intelligently.

　　At present, two-thirds of the new cases in COVID-19 come from rural areas, and about 30% of the urban population has been vaccinated with at least one dose of COVID-19 vaccine, compared with only 15% in rural areas.

　　Local health workers also said: "When we go for virus testing or talk to them, sometimes people will tell us to leave, otherwise they will beat us, and sometimes they will throw stones and bricks."

　　This week, the Ministry of Health of India pointed out that the "Delta+"strain has stronger transmission ability, and adjusted the classification of this new strain from "variant of interest" to "variant of concern".

　　Maharashtra Health Minister Top:We have issued instructions to all subordinate officials to pay close attention to infection cases related to "Delta+"variant.

　　According to a report by the BBC on the 24th, the "Delta+"strain has been found in at least 10 countries including the United States, Britain, Portugal, Switzerland, Japan and Russia. Lisbon, the capital of Portugal, has recently entered a full blockade every weekend.

　　Portuguese National Guard spokesperson Cagnotto:Drivers know the rules, they know that it is forbidden to leave and enter Lisbon metropolitan area, and the traffic on Friday afternoon is much less than usual.

　　Newsstand operator:I think all measures to reduce the number of cases are good. I am located in the city center and I see that all foreign tourists don’t wear masks.

　　Lisbon and the Tejo Valley are the regions with the most serious epidemic in Portugal.

　　According to the report released by the Portuguese National Institute of Health, among the recent new cases in Lisbon, the infection cases related to the "Delta" mutant strain accounted for more than 60%, and some local epidemiologists believe that this proportion has reached 70%.

　　Due to the obvious deterioration of the epidemic, the United Kingdom removed Portugal from the British green navigation list in early June.

　　Simon, an English tourist in Portugal:I’m very angry. I’ve missed half my holiday. Now it costs me a lot of money to change my flight in order not to be quarantined after returning home.

　　On June 21st, Portuguese Health Minister temido said that the spread speed of the "Delta" mutant strain has exceeded the speed of vaccination.

　　Portuguese cabinet spokesman da Silva:We think it’s very important now not to let Lisbon’s current difficulties spread to other regions.

　　On June 23rd, the gymnasium of Lisbon University was temporarily used as the vaccination center for COVID-19, which was operated by the Portuguese Armed Forces to vaccinate people over 50 years old. President De appeared at the vaccination site.

　　Portuguese President De:We are here to call attention to this priority, and the Portuguese are racing against time with unity and cooperation.

　　On June 24th, during the EU summit, German Chancellor Angela Merkel said that Germany and Europe were treading on thin ice.

　　German Chancellor Angela Merkel:We need to be vigilant, especially in the face of Covid-19’s new variety "Delta", which reminds us to be cautious.

　　A few days ago, Merkel had just received the second dose of COVID-19 vaccine.

　　Willer, Director of robert koch Research Institute:Since the second week of June, because there is always a certain time lag in statistics, the proportion has reached 15%, but we think the proportion will certainly be higher today.

　　German Federal Minister of Health Span warned that it was only a matter of time before the Delta strain continued to spread and became the most important strain in Germany.

　　On June 23rd, the European Center for Disease Control and Prevention released the latest epidemic model forecast: It is estimated that by the beginning of August, 70% of the newly confirmed cases in the EU and EEA countries will be caused by the "Delta" mutant strain, and by the end of August, this proportion will rise to 90%.

　　Kruger, Director of the WHO Regional Office for Europe:The worrying "Delta" variety, showing stronger transmission and some immune escape ability, is preparing to take root in the European region.

　　In contrast, on June 24th, US President Biden appeared in Raleigh, the "Oak City" in North Carolina. According to Bloomberg, this is a vaccine trip.

　　US President Biden:The dangerous mutant strain continues to spread, and it is now a very common variant in the United States. People who are not vaccinated are very vulnerable, which is also a concern of experts about the "Delta" strain.

　　In May this year, Biden confidently announced the next stage of epidemic prevention goal in the United States, that is, 70% of American adults should be vaccinated with at least one dose of COVID-19 vaccine before July 4, the day of American independence, and 160 million American adults should be vaccinated with two doses.

　　However, according to the CDC data, as of June 22nd, only about 65% of adults in the United States have received at least one dose of COVID-19 vaccine. Only 55% in North Carolina. White House officials admit that Biden’s epidemic prevention goal may not be completed as scheduled.

　　White House COVID-19 Epidemic Response Coordinator Zienz:There is still a lot of work to be done in this country, especially for people aged 18 to 26. The fact is that many young people in the United States feel that the COVID-19 epidemic will not affect them, and they have no desire to get vaccinated.

　　On June 24th, a strange conversation between Biden and CNN reporter further aroused people’s anxiety.

　　In the eyes of some Americans, Biden was once again questioned as to whether he could be trusted, except for the new nickname "Joe the Terrible".

　　Defense lawyer Woodfield:For the first time in the history of our country, private employers told their employees that as a condition of your employment, you must take part in the vaccine test, which has never happened in the history of our country.

　　In Houston Methodist Hospital, Texas, hundreds of employees were fired or forced to resign because they didn’t want to be vaccinated. Nurse bridges took the lead in bringing a lawsuit against the hospital.

　　Bridges, a former nurse at Houston Methodist Hospital:At first, 117 people joined us, and now we will add another 70 people. We hope that Methodist hospitals will be responsible for their actions, and we hope that the public will know that we should not lose our jobs.

　　Bloomberg pointed out that the COVID-19 epidemic is spreading rapidly in several states with insufficient vaccination, especially in Missouri and Utah, where more and more young people go to hospitals. These data release a clear signal that the epidemic in the United States has rebounded.

　　Frederick, Chief Executive Officer of Missouri Mercy Hospital:At the end of this week, 60% to 65% of the patients who entered the intensive care unit were under 40 years old, which was shocking compared with last year.

　　According to the data released by the US Centers for Disease Control and Prevention on June 22nd, more than 20% of the newly confirmed cases in the United States in the last two weeks were infected with the "Delta" strain, while in the report released on June 8th, this figure was only about 6%.

　　Fauci, director of the National Institute of Allergy and Infectious Diseases:Now this proportion is 20%, and it can be predicted that it will become the main virus-causing strain in the next few weeks to a month.

　　At present, the high-profile European Championship is in full swing in 11 European countries, and in the face of the fierce counterattack epidemic, UEFA is also very headache about what to do in the next competition.

　　Not only that, there is only less than one month before the opening of the Tokyo Olympics. This week, Japanese public health experts also said that "the Tokyo epidemic tends to rebound, which is very worrying."

　　On June 25th, Beijing time, UEFA announced the best team in the group stage of the European Championship, among which Cristiano Ronaldo, the Portuguese star who was crowned the top scorer in the history of the European Championship finals, was selected with the highest score.

　　Wembley Stadium in London, England will be the venue for the semi-finals and finals of the European Championship. On June 22nd, UEFA announced that the British government has agreed to further increase the attendance rate of Wembley Stadium during the European Championship, and the opening rate of the stadium will increase from 25% during the group stage to 75%, which means that more than 60,000 spectators will be accepted in each of the three semi-finals on July 6th and 7th and the final on July 11th.

　　Wembley Stadium will witness the largest audience of British sports events in 15 months, the British Department of Digitalization, Culture, Media and Sports wrote on the top official Twitter.

　　British Health Minister Hancock:The European Championship is going well. The final will be held at Wembley Stadium. I also went to Wembley on Friday night. It was great to hear the noise of the crowd again.

　　However, the recent obvious deterioration of the epidemic in Britain has also caused many people to worry about whether holding large-scale events here will bring risks.

　　Italian Prime Minister Mario Draghi:Yes, I advocate that the finals should not be held in countries where the risk of infection is growing rapidly.

　　German Chancellor Angela Merkel:Britain is a high-risk area for virus variants, which means that anyone from Britain to Germany will need to be quarantined for 14 days.

　　Since May, the number of newly confirmed cases in Britain has increased rapidly, and has recently rebounded to more than 10,000 cases per day.

　　On June 25th, the British Ministry of Public Health said that among the newly confirmed cases in the past week, 96% were caused by the "Delta" strain, compared with 99% in the previous week, and the cumulative number of people suffering from the "Delta" strain in Britain has reached 11157.

　　British Prime Minister Johnson:This is why we are so worried about the "Delta" variant, which is now spreading faster than the third wave of epidemic predicted in February.

　　On June 18th, the match between England and Scotland was held at Wembley Stadium, and a large number of Scottish fans "went south" into London, which brought a lot of pressure to the prevention and control of the epidemic in London.

　　On June 13th, Sadiq Khan, the mayor of London, was photographed celebrating the 1-0 victory of the Three Lions in Trafalgar Square. The excited crowd seemed to have completely forgotten to observe the epidemic prevention regulations.

　　According to the British "Times" report, among the 24 teams participating in the European Championship, except England, Scotland and Wales, the countries and regions to which the other teams belong are all on the orange or even red list of the epidemic in the UK. According to the British epidemic prevention policy, they must be quarantined for 10 days after arriving in the UK. Previously, the British government granted "isolation exemption" to the players, coaches and staff of the participating teams in order to hold the event smoothly. However, UEFA requested that 2,500 officials and VIPs also be granted "isolation exemption" so that they can directly enter Wembley Stadium to watch the game.

　　This puts the British government in a dilemma. If it accepts UEFA’s request, it will arouse the dissatisfaction of its own people. If it refuses, UEFA threatens to move both semi-finals and finals to Budapest, Hungary, where the epidemic situation is well controlled, which is also unacceptable to Britain.

　　The same dilemma also happened in Japan. On June 20th, the Olympic Village of the Tokyo Olympic Games was opened to the media for the first time, and the place where more than 10,000 athletes from more than 200 countries and regions lived was finally presented to the world.

　　Seiko Hashimoto, Chairman of the Tokyo Olympic Organizing Committee:With regard to the response to the COVID-19 epidemic, up to now, 80% of all people from all over the world have been vaccinated.

　　However, just the day before, on the 19th, one of the nine members of the Ugandan delegation who arrived in Tokyo tested positive for COVID-19 screening at the airport. Japanese Olympic Secretary Tamayo Marukawa confirmed that this person was infected with the "Delta" mutant strain. However, all members of the Ugandan delegation had completed two doses of vaccination before going to Japan and provided negative test certificates within 72 hours. On the 23rd, another member of the Ugandan delegation was tested positive, and many Japanese workers who came into contact with it were also isolated, which cast a shadow over the upcoming Olympic Games.

　　On July 23rd, the Tokyo Olympic Games is about to open, less than a month from now. According to the Nihon Keizai Shimbun, about 94,000 people will enter Japan during the Olympic Games, which has sparked a debate about the number of spectators at the Olympic Games.

　　On June 21st, the Japanese government, the Tokyo Olympic Organizing Committee, the Tokyo Metropolitan Government, the International Olympic Committee and the International Paralympic Committee held five-party talks online, and it was formally decided that the number of people watching the Olympic Games on site should not exceed 50% of the venue capacity, with a maximum of 10,000 people.

　　Seiko Hashimoto, Chairman of the Tokyo Olympic Organizing Committee:We have received a suggestion that if no spectators are allowed to enter, we can hold the Olympic Games more safely.

　　Many experts, including Shigeru Omi, the chief medical consultant of the Japanese government, believe that it is the least risky way to hold an event without an audience.

　　Only in this way, the publicity effect of the Tokyo Olympic Games will be weakened. For the upcoming election of the Japanese House of Representatives after the Olympic Games, the boosting effect will also be discounted. Kyodo News noted that Prime Minister Suga Yoshihide was anxious about this situation.

　　Japanese Prime Minister Suga Yoshihide:If it is necessary to implement a state of emergency, I will respond flexibly, not open the stadium to any audience, and hold an event with public safety as the first priority.

　　According to the research forecast of Xipu Bo, a professor of epidemiology at Kyoto University, by July 23rd, the opening of the Tokyo Olympic Games, the positive cases caused by the "Delta" mutant strain will account for 70% of all newly confirmed cases.

　　According to the results of a poll released by Kyodo News, among 2,000 respondents, 86% are worried that the Olympic Games and Paralympics will lead to the further expansion of the epidemic, 40.3% think that the Olympic Games should be held in an empty venue, and 30.8% think that it should be cancelled.

　　Tokyo citizens:As a resident, I am worried that the city may become crowded and Covid-19 will spread further.

　　Regarding the situation of epidemic prevention and control, Indian immunologist Barr stressed that no matter what kind of Covid-19 is targeted at, "vaccination will always put you in a better position to fight infection".

On July 18th, recently, some owner users of Zhixing shared their experience videos in the user center on the Internet platform, and emphatically introduced the dining-related experience, and nicknamed the user center as "HarmonyOS Hotel" and "Wenjie Hotel".

IT House noticed that Yu Chengdong, managing director of Huawei and chairman of terminal BG, also shared his experience in "HarmonyOS Hotel" yesterday:

It’s very distinctive to come to HarmonyOS Zhixing User Center in Inner Mongolia for supper. We have launched more than 600 user centers across the country.Free vehicle inspection in summer, including More than 200 companies support HarmonyOS Zhixing starry night service., convenient for users to come after work, check a car,Have a mealFeel free to go home.

It is worth mentioning that Yu Chengdong also shared the menu of Guest Meal Week in Zhixing User Center in HarmonyOS, Inner Mongolia: the dinner time is 19:30-21:30, and during the period from July 14th to July 20th, the daily dishes are different, but they are all Chinese.Roughly including four main dishes+one soup+one fruit.The staple food is expected to be rice.

At present, the official meal price has not been announced yet. IT House called the local HarmonyOS Zhixing User Center and learned that,Car owners and users are free to eat, and no related fees are charged..

In addition, HarmonyOS Zhixing plans to build a 350+ user center in 2025.

　　Wen _ Dianbingtang

　　It is said that at the end of World War II, the German Third Reich, which was violently attacked by the East and West lines of the Allies, came to an end in the rumble of guns.

　　Driven by madness and despair, German scientists put all their eggs in one basket and put forward a large number of new weapon designs, such as the "Giant Mouse" super heavy tank weighing more than 1,000 tons and the "Silver Bird" space plane with a range of 20,000 kilometers. These weapons, which are divorced from rationality and common sense, are jokingly called "Nazi black technology" by future military enthusiasts.

　　Among them, there is a "black technology" with the strongest power and the largest amount of work-and it is also the most impossible to achieve. This is the protagonist of this article: the solar cannon.

　　The fantasy of the solar cannon originated in 1929. In this year, hermann oberth, a famous German rocket scientist, accidentally opened a shocking brain hole in the process of daily research: launching a huge reflector with a diameter of 100 meters into space, which can reflect sunlight to the earth at night. In this way, ordinary crops can enjoy the sunshine 24 hours a day, and the growth rate can be greatly accelerated, thus rapidly increasing the grain output of the fields. In addition, large cities can also get enough light, thus saving a lot of electricity consumed in the lighting system.

　　Oberth recalled: "The sun mirror I imagined is like a naughty student reflecting on the ceiling of the classroom with a mirror. If this light shines across the teacher’s face, it will probably cause him unhappiness. And I am a school teacher who has collected enough data to make this mirror. "

　　With the outbreak of World War II, oberth and his favorite pupil, the famous German rocket scientist Werner wernher von braun, were recruited into the German rocket research and development department to develop the famous V-2 rocket for the army. In the process, oberth revealed the idea of this orbital solar reflector to the German army. After understanding the specific working principle, the German army organized a group of experts to improve oberth’s ideas. In the end, the orbital solar reflector originally conceived for peaceful use was transformed into the doomsday weapon plan of the German army: the solar cannon!

　　In fact, reflecting sunlight as a weapon is not a brand-new design. As early as more than two thousand years ago, there was a legend in Greece that Archimedes used a reflector to focus sunlight and burn the invading Roman fleet. However, the Nazis magnified the power of this concept to an unprecedented order of magnitude this time. According to the German vision, as long as a giant concave mirror is launched into space and enough sunlight is gathered, it can produce an ultra-high temperature that no defense facility can resist, burn enemy warships on the ground and even destroy enemy cities!

　　At that time, it seemed that the idea of solar cannon as an orbital weapon was undoubtedly very advanced. Once it is realized, it is definitely conan the destroyer’s big killer. However, the rocket technology of World War II is still in its infancy. Nazi Germany consumed a lot of resources and only developed a V-2 ballistic missile with a bomb load of 1 ton. It is undoubtedly an idiotic dream to use it to launch solar cannons that must be deployed in high-altitude space orbit. After the war, oberth and Braun were captured by American troops together. During the interrogation, oberth poured beans out of the bamboo tube and gave the details of the solar gun plan to the American interrogators in detail.

　　When the news reached Life magazine in the United States, the olfactory-sensitive editor was immediately attracted by the theme "The Nazis tried to scorch the earth with a sun mirror". They started at full speed at once. In July 1945, when the Second World War was not completely over, Life magazine made this amazing secret weapon of Nazi Germany public.

　　According to Life magazine, Nazi Germany’s solar cannon is an unprecedented giant weapon and the largest artificial object ever designed by human beings. In order to focus enough sunlight and cause devastating killing effect, this weapon will be suspended in a space orbit with a height of 8,200 kilometers, with a reflector area of over 9 square kilometers and a weight of one million tons. Once completed, it will be more than 100,000 times more powerful than Archimedes’ mirror, and it can easily destroy any big city, which can be called killing people and killing Buddha!

　　According to the idea of Nazi scientists, the work of building a space station began with the launch of an unmanned rocket. When the rocket enters the 8200-kilometer-high orbit, it will unfold six long metal cables, which are only about 0.5-1.5 inches in diameter, and will be deployed in place by themselves under the rotation of the rocket as the starting skeleton of the solar cannon project.

　　Next, the subsequent rocket will transport a pair of sunglasses components from the earth to space. These sunglasses components are essentially hollow metal frames made of sodium. On the earth, high-purity metallic sodium will be rapidly oxidized and lose its luster. However, there is no such problem in space. Sodium metal has good reflection effect and low density, and it is an ideal raw material for sunglasses in the eyes of Germans. Along the skeleton, the sunglasses components are pieced together one by one, and the installation angles are slightly different from each other. Finally, a huge concave mirror can be assembled, and the solar cannon is finished.

　　After the solar cannon is completed, this huge mirror will leave a round hole with a diameter of 30 feet wide as a connecting channel. The cargo rocket launched from the earth will be inserted into this round hole in a seamless way to transport building materials and supplies for the solar cannon. In fact, as long as we compare the modern space station, we can find that the German design was too complicated. As long as the operation is a little careless, the launch vehicle is likely to cause irreparable damage to the docking channel, which will directly affect the safety of the solar cannon. However, in the 1940s, it was not easy for German scientists to have such a design.

　　The solar cannon is actually a giant space station, which needs to accommodate a large number of people for daily maintenance. To this end, German scientists deliberately launched various designs.

　　First of all, the energy problem of solar cannons should be solved. In this space station with an area of 9 square kilometers and a weight of millions of tons, the operation of any equipment needs the promotion of energy. Where does the energy come from? The reader’s first reaction may be to directly convert sunlight into electric energy. However, in the 1940s, the technology of solar cells was still far from mature, so the Germans chose the principle of steam turbine-placing a transparent totally enclosed water tank on the outside of sunglasses, using sunlight to heat water, generating high-temperature and high-pressure steam, driving the turbine to drive the generator, and then transporting the cooled water back to the water tank, thus generating a steady stream of electric energy.

　　Secondly, in the 8200-kilometer-high orbit, the interior of the space station is almost weightless. In order to make workers move relatively freely, scientists have designed special "space shoes", with magnets installed on the soles, which can be stably adsorbed on the metal floor to create an environment similar to the ground.

　　However, the next question is quite important. Living in space, where does the oxygen that workers breathe come from? How to get food?

　　The German solution made future generations feel incredible-pumpkin!

　　From the perspective of Nazi scientists, pumpkins can effectively consume carbon dioxide exhaled by workers and provide sufficient oxygen, and more importantly, pumpkins are nutritious and healthy food. As for eating pumpkins all day, will it lead to a decline in staff morale? Germans don’t seem to think too much. Maybe in their view, this is a problem that can be solved by preparing more spices. As a result, thousands of hydroponic farms were placed inside the space station, all of which were used to grow pumpkins. It is worth mentioning that these pumpkins can’t be directly exposed to sunlight, because there is a lack of air in outer space, which can’t filter out some cosmic rays that are unfavorable to plant growth. Therefore, some of the electric energy output by the generator of the space station is used for fluorescent lamps instead of sunlight to illuminate pumpkins and help them carry out photosynthesis.

　　After providing a suitable living environment, the next step is the control of the solar cannon. How to aim at a target and focus sunlight on a point is a very challenging job. Behind the mirror with an area of 9 square kilometers, there are many miniature rocket engines. By adjusting the thrust of the engine, the staff can push the solar cannon to rotate slowly. What needs to be explained here is that even with the back to the sun, the other side of the mirror is polished to minimize the solar radiation.

　　In addition to marveling at the huge amount of work, Life magazine thinks that the height of solar cannons is low, and the best deployment position should be geosynchronous orbit 36,000 kilometers away from the earth. Here, the solar cannon can keep relatively static with the earth, and the staff have enough time to adjust the angle of the mirror and aim at the target on the earth. In addition, American calculations show that the diameter of the spot reflected by the solar cannon to the earth may be 40 miles, which means that the focusing effect is not enough to produce any destructive power.

　　For this, oberth did not agree. "This beam is really not hotter than the sun on the equator, but if the diameter of the mirror is doubled, the irradiation intensity will be four times, and the temperature of the beam irradiated on the ground will be as high as 200 degrees. This beam may not be able to directly burn the city or blow up the battleship, but it can definitely cook the humans on the ground! "

　　When the war ended, oberth devoted himself to the study of UFO phenomenon, and firmly believed that human beings would one day be able to build the solar reflector he envisioned and put it into peaceful use. On December 28th, 1989, when the Iron Curtain of the Cold War was about to fall, oberth died quietly. At this time, his dream-the goal of making a sun mirror in earth orbit-has still not been realized.

　　What oberth didn’t know was that after the war, at the other end of the Iron Curtain, a Soviet rocket scientist was trying to realize his ideal.

　　In the late 1980s, Vladimir Sergevich Syromyatnikov (hereinafter referred to as Tennikov), a famous Soviet space scientist and inventor of the docking mechanism of Soviet/International Space Station spacecraft, came up with a solar reflector scheme to solve the lighting problem in the polar regions of the Soviet Union at midnight. Although the solar reflector he designed was not as crazy as the Nazi German solar cannon, it was enough to provide a full moon-like lighting effect for the area 5 kilometers above Fiona Fang. According to Tennikov’s idea, this design can completely ensure night lighting, making street lamps and flashlights a decoration.

　　Soon after, the powerful red empire collapsed, but Tennikov’s solar mirror plan was unexpectedly unaffected. On October 27th, 1992, the cargo ship "Progress M-15" was successfully launched with the solar reflector "Flag 2" designed by Tennikov. After completing the replenishment mission for the Mir space station, Progress M-15 left the Mir space station on February 4, 1993, and then launched a 20-meter-wide "Flag 2" solar reflector in orbit near the space station to carry out preliminary theoretical experiments. This experiment was quite successful. The "Flag 2" solar reflector successfully illuminated a 5-kilometer-wide area, and the brightness was almost comparable to that of the full moon! In the end, this solar mirror followed the "Progress M-15" into the atmosphere and burned out.

　　Tennikov was greatly encouraged and designed "Flag 2.5" again. According to his prediction, this 25-meter-wide improved solar reflector can produce brightness equal to 5-10 full moons when it is started, illuminating a circular area with a diameter of 7 kilometers. Unfortunately, after the launch, an accident occurred during the deployment of the "Flag 2.5" solar reflector. At that time, a lens was caught in the communication antenna of Mir space station, and the strong communication antenna quickly tore the lens, causing the sunglasses to lose control. In the end, this attempt failed, and this solar mirror, together with the cargo ship "Progress", was burned when it re-entered the atmosphere. Tennikov’s solar mirror plan was cancelled by the Russian Space Agency, which had poor financial resources, because of its high cost.

　　However, Tennikov didn’t give up easily. He went around trying to find new investors, hoping to carry on his solar mirror plan. In order to raise funds, Tennikov almost devoted his efforts to this project. Unfortunately, until his death in 2006, Tennikov had not raised enough funds to continue his "Flag" project.

　　Throughout the development of solar cannons, we can see that there are three obvious shortcomings that limit the development of this equipment.

　　First of all, the cost of building a solar cannon is amazing! According to oberth’s original idea, his solar cannon would cost $3 billion-an astronomical sum at that time. Even the Manhattan Project of the United States to develop nuclear weapons at the same time cost only $2 billion! Compared with the atomic bomb that can instantly destroy a big city, oberth’s solar cannons cost a lot, but even people on the ground are hard to kill, which is obviously not worth it.

　　At the same time, to build a huge solar cannon in space orbit, its engineering quantity and assembly difficulty are very amazing. Although oberth once imagined that this million-ton solar cannon could be built in 15-20 years. But until today, the most Ushizo object assembled by human beings in Earth orbit is only the "International Space Station" with a total weight of 500 tons-this is the result of the cooperation of dozens of countries, including the United States and Russia, in 20 years! Moreover, compared with the international space station built by docking module, the engineering complexity of the solar cannon is several times more difficult: because each mirror must be accurately installed in place, the workers responsible for assembling the solar cannon must wear heavy spacesuits and manipulate wrench tools to install the mirrors one by one, which is difficult for ordinary people to imagine. Even by the time standard of building the International Space Station, it takes at least a dozen generations of efforts and hundreds of years to complete a solar cannon with a weight of one million tons!

　　In addition, the vulnerability of solar cannons is also a problem that people must consider. Although solar cannons in orbit can intercept incoming anti-satellite missiles by reflecting sunlight. However, in wartime, the enemy is likely to use a large number of missiles to launch a saturation attack on this orbital mirror. As long as one missile breaks through the interception line and hits the solar cannon, it can destroy a large number of mirrors and make this expensive special weapon a waste. Moreover, even in peacetime, solar cannons face a major threat-space junk that can be seen everywhere in space orbit. Because of its huge size, the solar cannon has become an excellent target for space junk flying at high speed. As long as space junk destroys one of the mirrors, the effect of the whole solar gun system will be greatly reduced.

　　Although the practical application of solar cannons has encountered many difficulties, this does not mean that no one will carry forward the concept of orbital reflector. On March 23, 1983, President Ronald Reagan announced the strategic defense plan of the United States-the famous "Star Wars" plan. In this ambitious plan, the US military also used an orbital light reflector. However, the light source of these light reflectors is no longer ordinary sunlight, but high-energy laser emitted from the ground! According to the U.S. military’s vision, this weapon can directly reflect the high-energy laser beam emitted by the ground excimer laser transmitter and destroy the enemy ballistic missiles that are on the rise. Once a nuclear war breaks out, the United States can use this weapon to quickly destroy the incoming Soviet ballistic missiles, and then launch a retaliatory nuclear strike without worrying that the nuclear bomb will fall on its own head.

　　Of course, such a powerful weapon still needs to pay a price. Because the laser beam must penetrate the atmosphere, and then be transmitted to the attacking satellite through the relay satellite and then refracted to the target, the laser transmitter on the ground must be very powerful to be competent for this work. In order to achieve this goal, Americans put a lot of money into the development of ground lasers. Until the "Star Wars" project was cut by President Clinton in 1993, the ground laser station for providing light source was still not developed. In the end, the orbital reflector scheme was abandoned by the US military, and the development experience related to the project was applied to other laser weapon research projects of the US military.

　　Although the solar cannon and its derivative products have not been successful in reality, it does not mean that it cannot be a popular weapon in various cartoons, games and movies. In the story of the classic sci-fi cartoon "mobile suit 0079", Ji Wengjun owns a solar shaped gun transformed from a colonial satellite. In the subsequent development of the plot, this solar cannon directly swept the fleet of the Union Army and destroyed one-third of the main ships of the other side. This led to a forced attack by the Union Army of the Earth, which destroyed this threatening solar shaped charge gun. However, this solar energy gathering gun provides energy through the surrounding solar panels, which is essentially different from the working principle of the solar energy gun envisioned by oberth.

　　Besides appearing in the mobile suit series, Sun Cannon also appeared in the Resident Evil series of games. In the plot background of the game Resident Evil: Revelation, a maritime city in the Mediterranean Sea, Tra Griga, collects sunlight through an orbiting solar reflector to provide sufficient solar energy for lighting. When the "Hound" organization launched a biochemical terrorist attack in the city, which turned the whole city into a hell full of monsters, the top management of the Federal Bioterrorism Committee decided to turn the solar reflector into a solar cannon and emit a high-energy beam to completely destroy the city. As Terra Griga was completely reduced to ashes by high-energy beams, the story of the game-Floating Island Panic came to an end.

　　However, the most original work of oberth’s solar cannon design is the last 007 film "Die Another Day" starring pierce brosnan. In this movie, James Bond’s enemies have a solar cannon in orbit exactly as oberth imagined. In the film, this solar cannon destroyed the rocket car driven by Bond, the huge ice sculpture building, the missiles that attacked the solar cannon, and even the transport plane that the villain was riding! Perhaps the director of the film wants to pay tribute to oberth, the visionary of the orbital solar reflector. When the villain in the film announced the existence of the solar gun, he deliberately advocated that the orbital gun was only used for "civil lighting".

　　Although oberth’s idea of a solar cannon, and the idea of an orbital reflector derived from it, has not yet come true. However, his solar cannon is still active in many sci-fi works and is regarded as a classic sci-fi technology setting, which makes people feel very gratified. With the continuous development of space science and technology, maybe in the near future, someone will follow oberth’s legacy, solve the technical problems that limit the development of solar cannons, and finally develop an orbital reflector for the peaceful use of solar energy for the benefit of mankind!

CCTV News:According to the construction schedule of China Space Station,In May and June this year, the Tianzhou-2 cargo spacecraft and the Shenzhou-12 manned spacecraft will be launched respectively.Among them, there are three astronauts on Shenzhou 12 who will form a flight crew and will stay in orbit for three months.

At present, the Long March 7 Tele-3 launch vehicle, which carried out the launch mission of the Tianzhou-2 cargo spacecraft, has completed all the development work before leaving the factory, and has arrived safely at the Wenchang Space Launch Site in Hainan. Together with the Tianzhou-2 cargo spacecraft that has arrived earlier, the final assembly and testing work in the launch site are carried out as planned. According to the plan, 11 missions will be carried out in succession this year and next, including three space station cabin launches, four cargo spacecraft launches and four manned spacecraft launches. The on-orbit construction of the space station will be completed in 2022, and all the mission objectives of the "three-step" development strategy of the project will be realized. At this time, it is exactly 30 years since the manned spaceflight project was officially launched.

The manned spacecraft carrying out the Shenzhou-12 manned space mission and the Long March-2 F-12 carrier rocket have also completed all the development work before leaving the factory. At present, they have been safely delivered to Jiuquan Satellite Launch Center in batches to carry out the assembly and testing work in the launch site, and the astronaut crew carrying out the manned space mission is undergoing intensive training. The last time China launched the Shenzhou manned spacecraft was on October 17th, 2016. Shenzhou XI carried out the sixth manned mission in China. At that time, the astronauts who took the Shenzhou XI flight were Jing Haipeng and Chen Dong, who worked in orbit for 33 days. Among them, Jing Haipeng flew for the third time and was the astronaut who went into space the most times so far.

　　Xinhua News Agency, London, August 31 (Reporter Gui Tao) On August 31, several British cities held demonstrations to protest against Prime Minister Boris Johnson’s adjournment of Parliament.

　　On the same day, tens of thousands of people marched in London, Manchester, Oxford, Liverpool, Leeds and Belfast, the capital of Northern Ireland. They shouted slogans and accused the Johnson administration of despising democracy and deliberately pursuing "no agreement to leave the European Union". There are both "Brexit" supporters and "Stay in Europe" supporters in the marchers.

　　The British Parliament, which is currently in summer recess, will resume on September 3rd. Johnson asked the parliament to adjourn again from September 9 to September 12, and the adjournment lasted until October 14. Queen Elizabeth II recently approved this request.

　　Critics believe that the deadline for Brexit on October 31 is approaching. If Parliament adjourns again, there will be only two weeks left for Members to exercise their rights on the issue of Brexit. Johnson’s request to adjourn the parliament again is to stop the members’ efforts to oppose "no agreement to leave the European Union". However, Johnson insisted that there was enough time for parliamentarians to discuss the issue of "Brexit".

　　The winter moon has arrived, and it is near the end of the year. The real estate market in 2021 was ups and downs.

　　In the first half of the year, real estate development loans, sales area and sales performance were very active, and house prices rose steadily in some cities. The turning point appeared in the middle of the year, and the financial regulation and control policies such as the "three-line and four-file" housing enterprise financing management rules and the loan concentration management of banking financial institutions gradually took effect, especially after the liquidity risk of individual large housing enterprises appeared as the "fuse", the market obviously cooled down in the second half of the year. With the sharp decline of the market, the virtuous circle of the real estate industry has been broken to some extent.

　　The Central Economic Work Conference held a few days ago proposed that the city should promote the virtuous circle and healthy development of the real estate industry, and made clear the focus of the current and future development of the real estate market. At present, the debt problem of some real estate enterprises is more prominent, and real estate sales, investment and land transfer all show signs of slowing down. In some cities, there is a wait-and-see mood of falling house prices and buying houses. Especially for areas with high industrial dependence, once the real estate market slows down excessively, it may trigger a more complicated risk transmission chain.

　　Real estate has a large scale, a long chain and a wide range of aspects, which accounts for a fairly high share in the national economy, fixed assets investment of the whole society, local fiscal revenue and total loans of financial institutions, and has an important systematic impact on economic and financial stability and risk prevention.

　　How to realize the virtuous circle and healthy development of real estate industry? Stable expectation is an important prerequisite. The Central Economic Work Conference proposed to strengthen the expected guidance. Many people are not optimistic about the future development of the industry due to the debt crisis of individual housing enterprises and the downward pressure on the real estate market. In fact, although there are serious debt problems in individual real estate enterprises at present, it is still a case, because the enterprises themselves are not well managed, and their influence need not be exaggerated. The overall healthy development trend of China’s real estate market will not change, and the risks of individual enterprises will not affect the normal financing function of the medium and long-term real estate market.

　　At the same time, the reasonable housing needs of buyers are being met. The Central Economic Work Conference proposed that it will support the commercial housing market to better meet the reasonable housing needs of buyers. According to the data released by the central bank on December 13th, the balance of individual housing loans was 38.1 trillion yuan at the end of November, an increase of 401.3 billion yuan in that month, an increase of 53.2 billion yuan over that in October. The recent increase in the balance of personal housing loans is conducive to better meeting the mortgage demand of the first and improved housing.

　　On the basis of stable expectations, the supply and demand blocking point is expected to break through, and a virtuous circle of the real estate industry is expected. The cooling of the real estate market is easy to be transmitted to other links. When the transaction volume of second-hand houses decreases and fewer buyers buy new ones, the new house market may be neglected, while the sales of the new house market directly affect the payment of enterprises. Once the funds are insufficient, it will reduce the enthusiasm of enterprises to take land, and then the cooling will be transmitted to the land market. It can be seen that one link is stagnant and it is easy for the whole market to "turn". To achieve a virtuous circle and healthy development of the real estate industry, efforts should be made to control the liquidity risk of housing enterprises and avoid the transmission of local risks to the whole system. At the same time, it is necessary to smooth all links in the chain of "financing, land acquisition, sales, loans and payment". The improvement of the financing of housing enterprises and the credit environment of buyers will help the real estate industry to further realize a virtuous circle.

　　To achieve a virtuous circle and healthy development of the real estate industry, enterprises need to constantly explore new development models. The development model of high leverage, high debt and high turnover in the real estate industry in the past 20 years has been unsustainable; On the whole, China will gradually transition from incremental development of large-scale demolition and construction to stock transformation; From the perspective of housing supply, from the past, we paid more attention to buying and renting, and changed to renting and buying at the same time. All these decide that real estate enterprises should adapt to the changes and explore new development models.

　　In the process of solving the housing problem, housing leasing will play an increasingly important role. The Central Economic Work Conference proposed that we should adhere to both rent and purchase and accelerate the development of the long-term rental market. Specialized and large-scale housing leasing enterprises are an important carrier to improve professional services in the leasing market. Factors such as high cost and narrow profit space in leasing industry hinder the specialization and scale development of enterprises. Statistics show that the institutionalization rate of housing leasing in first-tier cities in China is less than 15%. Therefore, to speed up the development of the long-term rental market, we should speed up the cultivation of specialized and large-scale housing rental enterprises.

　　To realize that all people have a place to live, housing security cannot be absent. The Central Economic Work Conference proposed to promote the construction of affordable housing. China’s housing security system has completed the top-level design, including public rental housing, affordable rental housing and shared property housing. Among them, affordable rental housing, which focuses on solving the outstanding housing problems in big cities and alleviating the housing difficulties of new citizens and young people, will become the top priority of affordable housing in the new development stage.

　　The central economic work conference once again stressed that "housing is not speculation", indicating that the bottom line cannot be broken. To promote the virtuous circle and healthy development of the real estate industry, we should take "keeping the word steady, striving for progress while maintaining stability" and "trying to smooth the national economic cycle" as the starting point, instead of having the mentality of stimulating and speculating on real estate.

　　Xinhua News Agency, Wuhan, March 30th (Reporter Zhao Jiantong, Liao Jun, Xiong Qi) When it comes to the football super league, what most fans can think of is "Premier League", "Portuguese Super League" or "Super League". However, last Sunday, a primary school in Wuhan started a "Wan Chao" league with 28 teams. Ten rounds of matches will be held every week until the end of the semester.

　　Wansongyuan Road Primary School has a long history of developing campus football, and has trained athletes such as Tu Shengqiao, Hao Junmin and Hanlin Yao. In the 2022 China Youth Football League, "Wanxiao" participated in six groups in Wuhan Division and won the championship and runner-up in four groups. Xinhua News Agency reporters found some unique details after attending the opening ceremony of the "Wan Chao" League in the new semester and observing many games, which may provide a glimpse of the school’s many successful experiences in campus football.

　　A 61-page order book

　　After the opening ceremony of the league, the game began. The rapid transition from the ceremony venue to the football field, from the coach leading the students to warm up before the game to the skilled referee, from the ambulances and medical staff prepared on the sidelines to the guzheng performance performed by the middle school students, the orderly and orderly organization and implementation of the professional "Wan Chao" League is impressive.

　　When turning over the 61-page "Wan Chao" League Order Book containing 14 major items, everything seems to have an answer. Among them, the rules, schedules and other provisions have extremely detailed provisions on the division of activities, competition processes and award selection rules, and the professional level is almost comparable to that of professional competitions.

　　"Wan Chao" League also has some special settings. For example, students must have excellent cultural achievements to participate in the competition, talent shows should be interspersed at halftime, scores should be scored on and off the field according to age and formation, and the code of conduct that requires coaches to understand the advanced techniques and tactics of world football should be detailed.

　　Principal Xiong Liping introduced that this year, "Wan Chao" was upgraded from a campus football event to a mass sports compound event in Jianghan District. Six young teams and four adult teams were invited to join the league.

　　Among the four adult teams, there are three teams composed of hospital, bank employees and nearby residents, and one is the school coach team. In the competition system, the teams of Grade 5 and Grade 6 of Wanxiao were grouped into adult groups and will compete with four adult teams. In addition, this arrangement of "playing big with small" also implies the coach team’s deeper thinking about youth football.

　　Coach Deng Shijun said that this competition system is actually to provide a high-intensity competition environment for small players. "Football is not only a technical and tactical issue, but also involves psychological and social aspects. There was a child in the game just now. He was out of balance when confronted with strong confrontation. I think this is also a place where many children need to improve. "

　　Professional coach of Rooted Primary School

　　Deng Shijun, 51, is known as the "father of grass-roots football" in Wu Hanyou. He is the only primary school teacher in China who has obtained the qualification of AFC lecturer and AFC professional football coach, and is also the head of the coaching team for organizing the "Wan Chao" League.

　　According to the data of China Football Association, at present, only over 100 people in China hold professional-level coaching certificates. Although qualified to coach top professional clubs, Deng Shijun resolutely chose to take root in campus football and devoted himself to educating people for nearly 30 years.

　　Deng Shijun (third from right), lecturer of AFC and professional football coach of AFC. The picture is provided by the school.

　　"After playing the game every weekend, all the game materials will be copied back by the coach for analysis. On Monday, the coach will conduct a collective analysis meeting to guide the training content of this week."

　　"In fact, it lies in being serious or not," coach Deng summed up the uniqueness of "Wanxiao" in playing football. "I have always said that we should wait for the flowers to bloom. Only by paying a lot can we bring out the fine products. Make the grassroots solid, 10 years, 20 years, like Yugong Yishan, take your time. "

　　The "Wanxiao" coaching team currently has 10 full-time coaches. Most of these coaches have professional athletes’ experience, and all of them hold AFC C-level and above coaching qualification certificates. Coach Deng introduced that through the government’s purchase of services, the school introduced full-time coaches, which not only solved the work treatment problem of retired players, but also improved the professional level of campus football.

　　Change venues three times a day.

　　Every Sunday from morning till night, there are 28 teams, which are divided into children’s groups, senior and junior groups and adult groups. During the "Wan Chao" League, the school used an eight-person court to the extreme. After a game between senior and adult teams, the coaches quickly cut the whole field into three pieces with fences, and the six teams participating in the five-a-side competition immediately began to warm up. According to a coach, the venue will also be divided into six blocks for the follow-up three-person competition for children.

　　The fence on the site is actually a common "water horse" on the highway. After years of exploration, coaches found that this kind of tied "water horse" is better than ordinary mobile football purse seine — — It is convenient to carry, will not be knocked over or blown down by the wind, and can also bounce the ball to keep the rhythm of the game continuous.

　　Relying on the class form of group rotation and efficient use of the venue, "Wanxiao" meets the needs of more than 1,000 students in the whole school to have a football class once a week and more than 10 teams to carry out "four practices and one game" on an eight-person venue.

　　"Our venue will be repaired in July and August this year, and the venue will be widened." Deng Shijun said that after the venue upgrade, he hoped to make the "Wan Chao" League bigger and stronger.

　　Parents inside and outside the fence

　　Before the opening match of "Wan Chao" League, parents were already standing outside the wall on the street side of the stadium to watch the game, and the trail over 100 meters was crowded.

　　In fact, there are many parents in the crowd near the site within the fence. Zhang Zhihui is the father of a fifth-grade student, Zhang Mulang. He and several teammates’ parents volunteered at the league. These parents and volunteers are divided into different roles, some as photographers to take pictures and record videos for children, some as teaching assistants to help coaches lead the competition, and some on the sidelines to do some equipment and water delivery.

　　Wang Lingjie, the teaching director, said: "Parents have now formed a tacit understanding with the school. They know how to help coaches and teachers make up for their places. This is also a good process for parents to participate in the growth of their children. "

　　Deng Shijun said that with the support of the district government and other sectors of society, students don’t have to pay for "ten thousand small" training and competitions, and they can also receive free football equipment, so the burden on parents is reduced a lot.

　　According to the coaches, with the holding of the "Wan Chao" League, parents who used to take their children to play in off-campus training institutions on weekends now mostly let their children play in school.

　　Zhongxin. com, Nanjing, May 11th (Xu Linhua, Xu Shanshan) "I lend my dearest mother to you", "My mother is an angel guarding this city, an angel with light" and "My mother is angels in white with wings" … … On the eve of the International Nurses’ Day on May 12th, the children of nurses sketched their parents’ images in various ways, such as painting, calligraphy, photography and poetry.

　　"I lend my dearest mother to you."

　　Zuo Jingfang of Jiangsu Cancer Hospital (affiliated tumor hospital of Nanjing Medical University) rushed to Huangshi, Hubei Province in 2020 with Jiangsu medical aid team, and served as the head nurse of respiratory department of Huangshi Central Hospital, leading more than 100 nurses in Jiangsu and Huangshi to work in the front line. In April this year, she also participated in supporting nucleic acid collection in Jiangsu Province. Before Nurses’ Day, my son drew a picture with this theme, called "Borrowing Mom".

　　"I am one of the dual-employee families in the hospital. Everyone is busy. My lover often comes home late for surgery, and the children can only be taken care of by the elderly." Zuo Jingfang said. She wants to say "sorry" to her family and children. Because of work reasons, I often can’t take care of my family, so many schools are absent from parent-child activities.

　　"Although this profession is very hard, it has also gained a lot. After the COVID-19 epidemic, more and more people recognized us, and the relationship between doctors and patients became more harmonious. " Zuo Jingfang said.

　　"Wait for spring, the epidemic will be over" and "Xiaobai, Anti-epidemic Record"

　　Support Nanjing nucleic acid collection for 13 days in July 2021; In March 2022, he supported the nucleic acid test in Jiangbei New District for 16 days with the Jiangsu Provincial Team; In May, the team leader supported Nanjing nucleic acid collection … … This series of data records the anti-epidemic footprint of Jing Jiang.

　　Jing Jiang is a nurse in charge of the nursing department of Jiangsu Cancer Hospital and the mother of twins. Because he has participated in nucleic acid collection for many times, he has to be the team leader or team leader. Jiang Jing is busier than other team members, leaving little time for the children.

　　"Mom, where have you been?" "Mom went out to fight the virus." "Mom, what do you use to fight the virus?" "Wear white protective clothing, wash your hands frequently and disinfect your whole body." So, Jing Jiang’s son drew a picture like a comic book, called "Xiao Bai, Anti-epidemic"; My daughter’s work is called "When Spring Comes, the epidemic will be over". After the children drew, they couldn’t write many words, so Jing Jiang helped them write on the picture.

　　"I hope dad will help Shanghai win the virus as soon as possible."

　　"I was going to draw a picture of Jiangsu medical team’s anti-epidemic work in Shanghai with my daughter before the nurse’s day, but I can’t go home because the support work is not over yet." Jason Han Han smiled at the other end of the phone and said slightly embarrassedly.

　　As one of the few male nurses in the hospital, Jason has already been "battle-hardened". It has been 12 years since I joined the work in 2010. He said: "There are many young people in our group who haven’t worked for a long time, so I have to set an example. After all, I have more experience than them, and I have to take part in the anti-epidemic for a longer time and be more rigorous."

　　Zhang Jie has two daughters, the older is 6 years old and the younger is only 2 years old. He participated in aiding Shanghai to fight the epidemic, and his wife was studying in Hangzhou, Zhejiang Province. Because of the epidemic, both of them could not go home, so they had to entrust their children to their parents. "Want to daughter! I haven’t held my daughter for more than a month, and it must be false to say that I don’t want to! " Jason said that the support work is still going on, and all the players are working hard at the front line. The daughters all said, "I hope my father will help Shanghai win the virus as soon as possible and go home as soon as possible."

　　Nurse’s Day is coming, and Jason has set himself a goal: to become an excellent operating room specialist nurse, and "she is working hard in this direction at present".
