The details of the death of American seals were revealed: they were fiercely besieged by more than 100 IS elements

  [Global Network Military Report on May 7] According to a report on the website of the US Army Times on May 4, the US Navy "Seals" commandos who died in Iraq on the 3 rd were members of a rapid reaction force. Their task was to pick up a US military operational advisory group that was attacked by "Islamic State" militants in the Kurdish region of Iraq. At 7: 50 in the morning, after receiving the report of "the troops were attacked", the US military commander ordered the rapid reaction unit where the special forces staff sergeant Charlie Keating was located to join the battle and assist those US military advisers to evacuate. When Keating and his troops arrived in the village, they found that Kurdish armed forces and American military advisers were engaged in fierce melee with the enemy.

  A national defense official said on the 3rd that at 7: 30 in the morning, about 125 "Islamic State" militants suddenly attacked the town of Taylor Askov.The militants acted in groups, with 20 armored vehicles and several car bombs, trapping more than 10 US military operational advisers. These consultants were on a one-day mission in the local area at that time, meeting with Kurdish a freedom fighter militants who had several operational outposts near the area controlled by the Islamic State.

  "There were bullets everywhere," said Colonel steve warren, a spokesman for the US Department of Defense in Baghdad. He (Keating) was hit in this gun battle. " Warren said that Keating was shot at 9: 30 am that day, and was taken by helicopter to the US military medical center in nearby Abiel for treatment at 10: 19 am, but died shortly after.

  Warren said that it is very rare to use the rapid reaction force in Iraq. The battle on the 3rd was the first time in several months that an American army called for emergency operations support. Keating, 31, is the third American soldier killed in Iraq since the US-led Coalition forces began to fight against the "Islamic State". At present, the US military is sending more ground troops to combat the "Islamic State" in Iraq and Syria.

  The US military operational advisory group entered the town of Taylor Askov at dawn. The town is less than 5 miles (1 mile is about 1.6 kilometers) from the area controlled by the "Islamic State". Warren said that the U.S. military commander had ordered the rapid reaction force to assemble and stand by in advance in case the U.S. military "advice and assistance" team was in danger.

  The "Islamic State" militants and their convoy of 20 vehicles entered the area without the knowledge of US military consultants and Kurdish armed intelligence personnel. Warren said, "You can’t monitor every inch of land all the time."

  Warren said: "The enemy was able to gather enough troops in a very secret way, including several car bombs and some bulldozers, and of course their infantry. They were able to cross the local Kurdish armed defense line, cross the front line and advance rapidly to the town of Taylor Askov. There is their goal. "

  The photos of the battle posted by the "Islamic State" on social media show that its militants drove several American Hummer military vehicles equipped with simple armor and a modified pickup truck equipped with heavy anti-aircraft machine guns. Warren said that there is no evidence that the "Islamic State" militants knew that there were Americans in the town when they launched the attack.

  Warren said that shortly after the fighting started, American planes arrived over the town of Taylor Askov, including drones, F-15s and F-16s, several B-52s and A-10s. These planes dropped dozens of bombs, destroying all 20 armored vehicles of the "Islamic State" militants, as well as two cars, a bulldozer and three mortars. According to Warren’s estimation, 58 "Islamic State" militants were killed in the air raid.

Research: ferrets and cats are susceptible to Covid-19, which can cause "cat-to-cat transmission"

  Covid-19 is thought to originate from bats, and it is 96.2% similar to RaTG13 (collected by Shi Zhengli, Wuhan Institute of Virology, Chinese Academy of Sciences, in Yunnan, China in 2013) in nucleotide sequence level. However, it is a kind of novel coronavirus that has not been detected in humans and other animals before, and its appearance has brought many new problems to be solved urgently, including whether other pets, livestock and poultry may be infected by Covid-19 besides humans?

  On April 8th, local time, the top academic journal Science published the paper "Susceptibility of Ferrets, Cats, Dogs, and Different Domestic Animals to SARS-coronavirus-2" online. The purpose of this study is to find out some questions: Will Covid-19 be transmitted to other animal species, thus becoming a "reservoir" of infection? Covid-19 infection has many clinical manifestations in humans, ranging from mild infection to death, so how is it manifested in other animals? With the development of vaccines and antiviral drugs, which animals can be used to simulate the effects of these drugs or vaccines on humans most accurately?

  In order to solve these problems, research teams from the State Key Laboratory of Veterinary Biotechnology of Harbin Veterinary Research Institute of Chinese Academy of Agricultural Sciences and the National High-level Biosafety Laboratory of Animal Disease Prevention and Control evaluated the susceptibility of different model experimental animals, pets and livestock to Covid-19, infected Covid-19 through experiments, observed the clinical manifestations and pathological changes of vaccinated animals and cohabiting animals, and detected the viral load of organs and tissues, the emission of respiratory and intestinal viruses, and the seroconversion of antibodies against Covid-19 in animals.

  Their research shows that Covid-19 has weak replication ability in dogs, pigs, chickens and ducks, but it can replicate efficiently in ferrets’ upper respiratory tract and cats’ respiratory system and digestive system. Experimental infected cats can spread Covid-19 through the air; Some cats can cause serious illness or even death after infection, and the illness of young cats is obviously more serious than that of older cats.

  Histopathological observation confirmed that virus infection in cats can cause lung inflammation and intestinal mucosal damage to varying degrees. Immunohistochemical study showed that there were a large number of virus infections in mucosal epithelium and olfactory bulb cells of upper respiratory tract (nasal cavity, maxilla, tonsil), mucous gland epithelial cells of trachea and bronchial mucosa, and intestinal mucosal epithelium.

  The correspondent of this paper is Chen Hualan, academician of China Academy of Sciences, chief scientist of the innovation team of animal influenza basic and prevention research in Harbin Veterinary Research Institute of China Academy of Agricultural Sciences, Bu Zhigao, director of Harbin Veterinary Research Institute of Chinese Academy of Agricultural Sciences and director of the national high-level biosafety laboratory for animal disease prevention and control, and Wu Guizhen, secretary of the Party Committee of Institute of Viral Disease Prevention and Control of China CDC and director of BSL-3 laboratory. Previously, on March 31st, local time, the research team had taken the lead in publishing the research on the preprint platform bioRxiv.

  It is worth mentioning that the National High-level Biosafety Laboratory for Animal Disease Prevention and Control is one of the existing two P4 laboratories in China, and the other is in Wuhan National Biosafety Laboratory of Chinese Academy of Sciences. All the experiments of Covid-19 infection in this study were carried out in P4 laboratory, which was approved by the Ministry of Agriculture and Rural Affairs of China. Animal research and animal welfare programs were approved by the Animal Experimental Ethics Committee of China Academy of Agricultural Sciences.

  According to the press release issued by official website, Harbin Veterinary Research Institute of Chinese Academy of Agricultural Sciences, different coronaviruses have been prevalent in mammals and poultry, but most of these coronaviruses are limited to specific species of animals and generally cannot infect humans. Similarly, several common coronaviruses in humans do not infect other animals. However, some coronaviruses from bats, such as SARS and MERS virus, can often infect many animals and humans.

  At present, Covid-19 is popular among a wide range of people in the world, and the risk of introducing animals in close contact with human beings is increasing. Therefore, it is urgent to study the susceptibility of domestic animals in close contact with human beings to Covid-19, evaluate whether domestic animals are exposed to Covid-19 hazards and become potential intermediate hosts, and provide scientific basis for prevention and control of Covid-19.

  In addition, in view of the current global epidemic situation of COVID-19, it is very likely that it will evolve into a common infectious disease, and it is urgent to establish a stable and reliable animal infection model to meet the needs of vaccine and drug research and development evaluation.

  The research team stressed that the monitoring of cat COVID-19 should be regarded as an auxiliary means to eliminate the current Covid-19 epidemic. They called for close monitoring and protection of cats in epidemic areas, avoiding their contact with infectious sources and preventing them from becoming possible transmission hosts or storage hosts.

  In addition, it was previously questioned that cats infected with COVID-19 were caused by large doses under laboratory conditions. However, in addition to this research, on April 3rd, Academician Jin Meilin, professor of the State Key Laboratory of Agricultural Microbiology of Huazhong Agricultural University, director of the Key Laboratory of Veterinary Diagnostic Preparations of the Ministry of Agriculture, director of the Research Center for Emerging Infectious Diseases of Wuhan Institute of Virology, Chinese Academy of Sciences, and researcher Shi Zhengli, director of the Key Laboratory of Highly Pathogenic Biology and Biosafety of Chinese Academy of Sciences, also published a study on the preprint platform bioRxiv. Through the investigation of cat serum, they found that the serum ELISA test of 102 cats collected after the outbreak of COVID-19 in Wuhan showed that the serum from 15 cats (14.7%) was positive for Covid-19 receptor binding domain (RBD).

  Nadia, a 4-year-old tiger from Bronx Zoo in new york, USA, was recently diagnosed with Covid-19. On April 5, local time, the US Department of Agriculture issued a statement confirming that a tiger in a zoo in new york was diagnosed with Covid-19, and several other lions and tigers also showed symptoms of respiratory diseases. Officials at the Bronx Zoo in new york said that nadia, three other tigers and three African lions had symptoms of dry cough and loss of appetite, but they are expected to recover. Public health officials believe that these animals were infected by an asymptomatic employee.

  Covid-19 can be replicated in the upper respiratory tract of ferrets for up to 8 days, but it will not cause serious illness or death.

  Ferrets are often used as animal models of human respiratory viruses. Therefore, the research team first tested ferrets’ sensitivity to Covid-19.

  Two Covid-19 strains were used in this study: F13-E from Wuhan South China Seafood Market and CTan-H from a patient infected with Covid-19.

  The research team inoculated 10 5 PFU (Plaque Forming Unit) F13-E or CTan-H into ferrets through nose respectively, and euthanized them on the 4th day after inoculation (P.I.). The turbinate, soft palate, tonsil, trachea, lung, heart, spleen, kidney, pancreas, small intestine, brain and liver of each ferret were collected, and the viral RNA was determined by qPCR and virus titration.

  Viral RNA:A in ferrets’ organs or tissues: A, F13-E, B, CTAN-H..

  The results showed that viral RNA and infectious virus were detected in the turbinate, soft palate and tonsil of all four ferrets, but not in other tissues.

  C, virus titer in organs or tissues of ferrets inoculated with F13-E, D and CTAN-H.

  The research team believes that these results show that Covid-19 can replicate in the upper respiratory tract of ferrets, but it has not been detected in other tissues.

  In order to study the replication dynamics of virus in ferrets, the research team intranasally inoculated 6 ferrets with 10^5pfu of F13-E(3) or CTan-H(3), and then placed them in three isolated cages. On the 2nd, 4th, 6th, 8th and 10th day, ferret nasal wash and rectal swab were collected for virus RNA detection and virus titration. At the same time, their body temperature and COVID-19 signs were monitored for two weeks.

  Viral RNA in the nasal wash of ferrets inoculated with F13-E(E) and CTan-H(F). Viral titers in the nasal wash of ferrets inoculated with F13-E(G) and CTan-H(H).

  The results showed that viral RNA was found in the nasal wash of all six ferrets on the 2nd, 4th, 6th and 8th day. Viral RNA was also found in some rectal swabs, but the copy number was significantly lower than that of nasal wash. Infectious virus was detected in nasal wash of all ferrets, but none of them was found in rectal swab.

  One ferret in each group developed fever and loss of appetite on the 10th and 12th days respectively. In order to investigate whether these symptoms are caused by virus replication in the lower respiratory tract, the research team euthanized the two ferrets on the 13th day and collected their organs for virus RNA detection.

  However, except for the ferret turbinate inoculated with CTan-H, the low copy number was detected, and no viral RNA was detected in any other tissues or organs.

  Pathological studies showed that two ferrets euthanized on the 13th day had severe lymphoplasmacytic vasculitis and vasculitis, the number of type II alveolar cells, macrophages and neutrophils in alveolar septa and alveolar cavities increased, and the lungs had mild bronchiolitis.

  The asterisk indicates that the animals were euthanized on the 13th day after inoculation, and the other four animals were euthanized on the 20th day.

  Covid-19 antibody was detected in all ferrets by ELISA and neutralization test, and the antibody titers of two ferrets euthanized on the 13th day were significantly lower than those euthanized on the 20th day.

  In order to further study whether Covid-19 was replicated in ferrets’ lungs, the research team inoculated 8 ferrets with 10^5 pfu of CTan-H through trachea, and euthanized 2 animals on the 2nd, 4th, 8th and 14th days, respectively, and detected virus RNA in tissues and organs.

  Among the two ferrets euthanized on the second day and the two ferrets euthanized on the fourth day, the researchers only detected viral RNA; in the turbinate and soft palate of one of them. Among the two ferrets euthanized on the eighth day, viral RNA; was detected in the soft palate of one ferret and in the turbinate, soft palate, tonsil and trachea of the other ferret. No viral RNA was detected in the two ferrets euthanized on the 14th day.

  These results indicate that Covid-19 can replicate in the upper respiratory tract of ferrets for up to 8 days without causing serious illness or death.

  At the end of the paper, the research team also mentioned that, comparatively speaking, Covid-19 is different from other influenza viruses that can replicate in the upper respiratory tract and lower respiratory tract of ferrets, and even human SARS-CoV. Covid-19 is only replicated in ferrets’ nasal bones, soft palate and tonsils. It can also replicate in the digestive tract, but even if the virus is inoculated in the trachea, the virus is still not detected in the lungs of ferrets.

  Cats are highly susceptible to "cat-to-cat transmission": the monitoring of cat Covid-19 should be regarded as an auxiliary means of epidemic prevention and control.

  It is worth noting that cats and dogs are in close contact with humans, so the research team thinks that besides laboratory animals like ferrets, it is very important to know the susceptibility of domestic animals that often live with humans to COVID-19 for the control of Covid-19.

  The research team first studied the replication of Covid-19 in cats. Five 8-month-old subadult domestic cats (inbred lines) were intranasally inoculated with 10^5pfu of CTan-H, and two of them were scheduled to be euthanized on the sixth day to evaluate the virus replication in their organs. Three cats were put in separate cages in the isolator. In order to monitor the spread of respiratory droplets, an uninfected cat was placed in a cage adjacent to each cat vaccinated with the virus.

  Because 8-month-old cats are aggressive, it is difficult to carry out routine nasal cleaning on them. In order to avoid possible harm, the research team collected the feces of these cats and checked the viral RNA in their organs after euthanasia.

  Virus RNA was detected in the nasal bone, soft palate and tonsils of two sub-adult domestic cats euthanized on the 6th day, and virus RNA was also detected in the trachea of one cat and the small intestine of the other cat. However, no viral RNA was detected in any lung samples of these two cats.

  Infectious viruses were detected in the nasal bones, soft palate, tonsils and trachea of these cats, but no infectious viruses were found in the small intestine with positive viral RNA.

  The spread of Covid-19 among cats.

  In the study of virus transmission, RNA virus was detected in the feces of two vaccinated cats on the third day, and RNA virus was detected in the feces of all three vaccinated cats on the fifth day. Among the three cats at risk of virus exposure, viral RNA was detected in the feces of one cat on the third day.

  Virus-infected cats with positive feces were euthanized on the 11th day. Virus RNA was detected in the soft palate and tonsils of the infected cats and in the nasal bones, soft palate, tonsils and trachea of the exposed cats, indicating that respiratory droplets spread between cats.

  On the 12th day, the research team euthanized the remaining cats. Viral RNA was detected in the tonsils of one virus-infected cat and the nasal bone, soft palate, tonsils and trachea of another virus-infected cat, but it was not detected in any organ or tissue of the two virus-exposed cats.

  Through ELISA and neutralization test, Covid-19 antibody was detected in all three cats inoculated with virus and one cat exposed to virus.

  Covid-19 replicates efficiently in respiratory system and digestive system of infected cats, causing pathological damage and inflammatory reaction. Histopathological and immunohistochemical study on cats that died or were euthanized three days after virus infection. (a) The arrangement of nasal mucosa epithelium is disordered, cilia fall off (arrow), and lymphocytes in lamina propria infiltrate (arrow). (b) The tonsil epithelial cells are degenerated and necrotic, and the surface of mucosal epithelium (asterisk) is covered with cell fragments and neutrophils (arrow). (c) Epithelial degeneration and necrosis of tracheal mucosa (arrow), with mucus (asterisk) mixed with a large number of cell fragments on the surface. (d) Epithelial necrosis of tracheal mucous glands and infiltration of lymphocytes (arrow). (e) Normal lung tissue structure of uninfected cats. (f) Aggregation of inflammatory cells in pulmonary blood vessels and coagulation of fibrin (arrow). (g) A large number of macrophages and lymphocytes infiltrated in alveoli, that is, alveolar septa. (h) Infiltration and proliferation of alveoli and alveolar septitis. (i) Some cells in the epithelium of small intestine are degenerated and necrotic, and lymphocytes in the lamina propria are moderately infiltrated (arrow). (j) A large number of epithelial cells of turbinate mucosa were positive for virus antigen (brown). (k) A large number of exfoliated cells in tonsil mucosa epithelium and mucosa surface were positive for virus antigen (brown). (l) A large number of virus antigens were positive (brown) in serous cells of tracheal mucous glands. (m) A large number of small intestinal mucosal epithelial cells were positive for virus antigen (brown). Ruler line A, I = 100 μ m, B-H, J-L = 200 μ m, M = 500 μ m

  The research team also repeated the above-mentioned replication and transmission research in sub-adult cats in young cats (70-100 days). Histopathological studies on the samples of young cats who died or were euthanized on the third day after being inoculated with the virus showed that the nasal cavity and tracheal mucosa epithelium and lungs of the two cats had a lot of damage.

  These results indicate that Covid-19 can be effectively replicated in cats, and young cats are more susceptible to infection. More importantly, the virus can spread from cat to cat through respiratory droplets.

  Next, the research team also studied the replication and spread of Covid-19 in dogs, and the results showed that dogs were less sensitive to Covid-19. Similar studies also show that pigs, chickens and ducks are not sensitive to Covid-19.

  Overall, the research team found that ferrets and cats are highly sensitive to Covid-19, dogs are less sensitive, and domestic animals including pigs, chickens and ducks are not sensitive to the virus.

  In addition, it is reported that Covid-19 uses angiotensin-converting enzyme 2 (ACE2) as its receptor to enter cells, and ACE2 is mainly expressed in type II lung cells and serous epithelial cells of ferrets’ tracheal-bronchial submucosal glands. Therefore, the research team believes that the potential mechanism to prevent Covid-19 from replicating in ferrets’ lower respiratory tract remains to be studied.

  The results of this study show that ferrets can be used as animal models for vaccine and drug evaluation in Covid-19. Dogs, pigs, chickens and ducks are not susceptible to Covid-19, which has important guiding significance for the traceability of virus hosts; More importantly, cats are highly susceptible to Covid-19.

  The research team called for close monitoring and protection of cats in epidemic areas to avoid contact with infectious sources and prevent them from becoming possible transmission hosts or storage hosts. The monitoring of cat COVID-19 should be regarded as an auxiliary means to eliminate the current Covid-19 epidemic.

It is rare for the two countries to openly disagree. Whether to extradite Assange will stir up US-Australia relations.

  [Global Times special correspondent in the United States Zhang Sisi Global Times special correspondent Wang Cong] "Whether Assange can be free is widely regarded as a judgment of the Australian government’s influence on the Biden administration in the United States." The Associated Press reported on July 30th that since the Labor government came to power last year, Australia has been trying to persuade the United States to terminate the prosecution of Assange, the founder of Wikileaks. However, in the recent annual meeting between US Secretary of State Blinken and Australian Foreign Minister Huang Yingxian, Blinken said that Assange was accused of committing a "very serious criminal act".

  The Associated Press reported that Blinken said during the talks that Assange was "suspected to be related to one of the most serious confidential information leaks in American history", and he understood Australia’s concerns and views on this matter, but urged Australia "as a friend, we should understand the concerns of the United States". Blinken also said that Assange’s "alleged acts may cause very serious harm to US national security" or even "life-threatening". Huang Yingxian responded that Australia has "made it clear publicly for many times" and that Assange’s case has been delayed for too long. Australia hopes that the United States can withdraw these allegations and settle the case as soon as possible.

  In addition, the Australian Sydney Morning Herald quoted Huang Yingxian as saying that the United States had "inconsistent" attitudes towards Assange and Chelsea Manning, another protagonist of the "confidential document leak case" and a former American army intelligence analyst. Manning was arrested for leaking about 700,000 confidential military and diplomatic documents to Wikileaks and was sentenced to 35 years in prison in 2013. However, in January 2017, former US President Barack Obama commuted Manning’s sentence before leaving office, which led to her release in May of that year.

  Assange has been detained in the high-security Belmarsh prison in south London since he was arrested by the British government from the Ecuadorian embassy in London in April 2019. In June, 2022, the British Home Secretary, Pruitty Patel, approved the request of the United States to extradite Assange. In July of the same year, Assange appealed the extradition order to the British High Court. According to the relevant laws of the United States, once Assange is extradited to the United States, he will be charged with espionage and improper use of computers in the United States, and he will face a maximum of 175 years in prison.

  According to the Sydney Morning Herald, Blinken’s statement is the "sharpest and most detailed" comment made by Biden administration officials on Assange. Blinken’s remarks mean a "rare public disagreement" between the United States and Australia, and highlight that "the Albanese government faces an arduous task in persuading Biden’s government to stop pursuing Assange". The Guardian reported that Blinken’s defense of the American accusation against Assange would be regarded as "a heavy blow to the efforts of the international community to rescue Assange".

  Assange, 52, was born in Australia and founded the Wikileaks website in 2006. In 2010, Wikileaks exposed a large number of American diplomatic cables and confidential documents of the US military during the Afghanistan War and the Iraq War, and exposed the war crimes of the US military. In 2019, after Assange was arrested in Britain, the United States immediately requested the extradition of Assange. Australian Prime Minister Albanese has repeatedly urged the US government to terminate the lawsuit against Assange. In May this year, Albanese said that he had expressed the Australian government’s position to the American and British governments that there was no benefit in continuing to imprison Assange.

  "Assange’s supporters reacted angrily to Blinken’s remarks." "Australia is the closest ally of the United States, and Blinken needs to understand the overwhelming view of the Australian people, that is, it is fed up with Assange’s endless imprisonment," said Barnes, legal adviser of the Australian Assange supporters organization, according to the Sydney Morning Herald. Assange must be released immediately and be reunited with his family. "

Essay: Talk about "America can’t be trusted" in Iranian eyes.

  Xinhua News Agency, Tehran, September 21st: Talk about "America can’t be trusted" in the eyes of Iranians.

  Xinhua News Agency reporter Gao Wencheng

  Iranian President Leahy made it clear in an interview with the American media a few days ago: "We can’t trust the United States." This sentence is not only his personal opinion, but also the consensus of Iranian society. From a government spokesman to an ordinary librarian, Iranian society now widely believes that — — "the United States cannot be trusted."

  The formation of this social consensus is closely related to the United States’ treachery and arrogance on the comprehensive agreement on the Iranian nuclear issue. In July 2015, after 10 years of arduous negotiations, Iran reached the the Iranian nuclear deal with the United States, Britain, France, Russia, China and Germany. However, in 2018, despite the opposition of the international community, the United States unilaterally withdrew from the Iranian nuclear deal and once again held high the sanctions stick to "exert extreme pressure" on Iran.

This is the scene of the new round of political director-level meeting of the Joint Committee of the Iranian Nuclear Comprehensive Agreement, which was filmed in Vienna, Austria on June 12, 2021. Xinhua News Agency (Photo courtesy of the EU delegation in Vienna)

  The United States’ wanton breach of contract and indiscriminate sanctions have caused great harm to Iran’s development. After the Iranian nuclear deal was reached, the United States lifted sanctions against Iraq, and Iran’s daily average oil export once reached 2.5 million barrels, with a record economic growth rate of 13.6%. However, after the United States unilaterally broke the contract and re-imposed sanctions, Iran’s oil exports once plummeted to only 100,000 barrels per day, and the economy shrank sharply year after year.

  Affected by US sanctions, the Iranian currency Rial has depreciated sharply in just a few years. Before the sanctions were restarted, more than 30,000 rials could be exchanged for 1 US dollar, but now it takes 30 Wan Li rials to exchange for 1 US dollar. The import and production costs of Iranian goods have increased significantly, and the shortage of materials has led to soaring prices and difficult people’s livelihood. Since 2018, the overall price in Iran has increased by about 85%, and food prices have doubled. Many Iranian families can’t make ends meet, and their lives are very tight. During the Chinese New Year, many Iranian children can’t put on new clothes, and many housewives have to think about buying a piece of meat for half a day.

  The pain of people’s livelihood has caused Iranians to pay close attention to the Iranian nuclear talks and look forward to the early lifting of sanctions. However, the indirect negotiations between Iran and the United States on the Iranian nuclear deal’s resumption of performance have been going on for nearly a year and a half, with ups and downs in the middle, and no results have been achieved so far. The current U.S. government said one thing and did another. Although it verbally expressed its willingness to return to the Iranian nuclear deal, it inherited the previous government’s policy of "extreme pressure" on Iraq, and even during the negotiations, it continued to raise the threat tone and increase the sanctions against Iraq.

  The current American government’s words and deeds are different, which has deepened the Iranian society’s cognition that "the United States cannot be trusted." Leahy said that if Americans want to reach an agreement, "why should they impose new sanctions on Iran during the negotiation?" Because the United States reneges on its word and has a bad track record, Iran is now very cautious in negotiations. The Iranian side has repeatedly asked the US to make a guarantee that it will not violate the contract again. Mohammad Marandi, consultant of the Iranian negotiating team, made it clear that Iran believes that corresponding provisions should be set, and if the United States breaches the contract again, it must pay the price.

  Iranian society believes that "the United States cannot be trusted" is a silhouette of the increasing bankruptcy of American national credibility in the international arena. A number of polls show that the global influence of the United States is generally declining. In order to safeguard hegemonic self-interest, the United States has repeatedly broken the contract and "retired from the group" and provoked conflicts and confrontations. Although the United States often pretends to be so-called "democracy" and "human rights", it is hard to hide the evil consequences of its perverse actions on other countries and even the whole international community.

Comprehensive evaluation of Sony Xperia Z1 with 20.7 megapixel G lens

    For today’s smart vendors, it is hard to imagine what is more important than diversified development. A few years ago, the mobile phone was still just a device for talking to us, but with the popularity of intelligent platforms, the mobile phone has changed from a communication device to a multi-functional intelligent terminal. Nowadays, in order to get rid of the homogenization of Android platform, Android manufacturers spare no effort to develop more potential of mobile phones. At this time, we will find that those manufacturers who can integrate the technologies of multiple product lines highlight more advantages than those who simply make mobile phones.

    When CEO Kazuo Hirai took office, we first heard the strategy of "One Sony". This is not the first time for Sony to integrate the technology of other product lines into mobile phones, just like the Walkman series and Cyber-Shot series that we once amazed. This time, Sony once again applied its camera technology to smart phones, and L39h (hereinafter referred to as Sony L39h) became the first product under the concept of One Sony. Just like the words in Kazuo Hirai’s mouth after the release of several DCDV devices in Berlin, "The next product can present the best part of Sony to you at one time."

    In terms of configuration, Sony L39h has adopted today’s flagship configuration without any accident. After the slow pace of last year, Sony’s flagship product has finally accelerated its pace in hardware this year, and has always maintained the strongest configuration at the same level as flagship models of other international brands. Like the Sony L36h released at the beginning of this year, Sony L39h uses a 1080p display screen. However, due to the overall improvement in photographing this time, the photosensitive element has also increased to 1/2.3 inch, so the overall thickness and length and width of the fuselage have increased to some extent in Bisogni L36h. The fuselage circumference of this model is 144× 74× 8.5mm, which will be thicker in the hand than that of Bisogni L36h, but relatively, it feels more comfortable because the frame adopts a brand-new flat cutting angle.

Sony’s first image flagship 5-inch 1080p Sony L39h

    Sony L39h is equipped with 2.2GHz MSM8274 Opteron 800 quad-core processor and GPU Adreno 330 image processor, and its outstanding performance is beyond doubt. At the same time, Sony L39h has also continued Sony’s waterproof and dustproof features, reaching IP55/58 level. This means that the phone has a built-in dustproof and waterproof design, that is, all ports and covers are closed, and the phone can be dustproof and can be placed in the deepest 1.5 meters of clean water for up to 30 minutes. Of course, taking photos is the biggest improvement of Sony L39h this time, and we will show it in detail later.

    Regarding the screen that most users pay attention to, the performance of the IPS screen in China made us feel amazing, but this amazing performance did not continue to the Sony L39h used in our evaluation. In other words, Sony L39h, like Sony XL39h, brings users a more vivid and clear visual experience through TRILUMINOS mobile display technology and X-Reality fast image processing engine, but this is only when we watch the screen from the front. When we look at the screen of Sony L39h from the side, the visual effect is still the same as Sony L36h. This really makes us regret. I wonder if the retail version is the same as the prototype used in the evaluation.

    Every year, the flagship product has maintained a high degree of consistency in appearance. In the previous interview, Mr. Morinuma, the designer of Sony L39h, explained that this is first to maintain the continuity and consistency of the design language. But also, each product will be fine-tuned in design and introduce a brand-new design based on the actual experience of users. This time, Sony L39h, like Sony L36h, has adopted a plane-like fuselage line, the camera has no protrusion, and the front and rear sides are also protected by double-sided glass, which gives people a high-end and exquisite impression visually.

Keys are still built into the screen.

    The screen size of Sony L39h is consistent with that of Sony L36h, which means that the change in the length of the fuselage mainly comes from the extension of the upper and lower ends of the screen. The place above the SONY English logo near the frame that looks like a groove is both the receiver and the breathing light. When charging or resting, the lights here will light up. In addition, the front camera located next to the logo has not changed, and it is still 2 million pixels, which is enough for self-timer and can also record 1080p video. At the bottom of the screen, we obviously feel that the "chin" Bisogni L36h of Sony L39h is getting longer, but the Android buttons are still built in the screen. Many netizens wondered why Sony didn’t put the Android button on this slightly longer chin. Although we didn’t get an official explanation, after actual operation, we found that with the growth of smart size, it is actually very difficult for us to hold the Android button on the chin of a mobile phone with a size of 5 inches or more. In other words, actually putting the buttons on the screen is more user-friendly in our actual operation, and it will be better if Sony can let users choose to hide or display these three buttons by sliding up and down in the future.

The bottom of the right side is provided with a hanging hole and a camera shutter.

    Sony L39h adopts a complete seamless design, and uses aluminum frame to make the mobile phone more durable. At the same time, it also uses this frame as an antenna through brand-new technology, which solves the disadvantage of poor call signal of metal body. Sony L39h still designed the main card slots and buttons on both sides of the fuselage, and attached dust plugs, thus maintaining a high degree of visual integration with the frame without affecting the appearance. On the right side, there is still the microSIM card slot, power button and volume button, and at the bottom, Sony L39h has added a photo shutter button, which is also convenient for users to take photos through the physical shutter button when they can’t touch the screen underwater.

The microSD card slot and data interface on the left side of the fuselage support MHL data transmission.

Metal contact for connecting magnetic attraction waterproof charging base

    The design of the left card slot of Sony L39h is somewhat different from that of Sony L36h. The positions of the microSD card slot and the data interface are upside down, with the microSD card slot at the top and the data interface supporting the transmission of microUSB and MHL at the bottom. Sony L39h also has an official standard waterproof charging base, and the metal contact below the data interface is used when connecting with this base.

    Another subtle change of L39h fuselage lies in the design of earphone hole, which is located at the top of the fuselage, but it is not equipped with dust plug like Sony L36h. Of course, users don’t have to worry about water coming into this earphone hole. Nowadays, the application of waterproof nano-coating technology is not uncommon. Personally, I think Sony chose to equip the interfaces on both sides of the frame with dust plugs, mainly for aesthetic considerations. In practical use, especially for people who listen to music on their mobile phones every day, the dust plug in the earphone hole is indeed redundant, and this design is just right.

The earphone hole at the top is not equipped with dust plug this time.

The bottom is almost a speaker, so it won’t block when you hold it.

    Another change comes from the position of the Sony L39h speaker. Sony L36h designed the speaker at the lower right side of the fuselage, which is the position of the Sony L39h camera shutter button. In actual use, if we hold the mobile phone in one hand with the right hand, the speaker will be easily blocked, and the movement of the hand will directly cause the sound of the speaker to be loud and small. This time, the speaker is designed at the bottom, which is a good solution to this problem. This change is still very intimate.

The back is still a whole glass design.

XPERIA capital logo at the bottom of the back

    The back of Sony L39h’s fuselage is still full of glass, and the explosion-proof membrane is also pressed for protection when it leaves the factory. This design is really beautiful, but it is also easy to be contaminated with fingerprints. Relatively speaking, white is the color with the least fingerprints among the three colors of black, white and purple. Sony’s English logo is located in the center of the fuselage. Above is the mark of NFC position, and below is the word XPERIA in all capitals. This time, it seems to emphasize the advantages of taking pictures. It is rare for Sony to mark the G word of G lens next to the camera, as well as the camera pixel size of 1/2.3 inch sensor and 20.7 million pixels. It can be seen that Sony is indeed full of confidence in taking pictures of this product.

    L39h is equipped with Android 4.2 jelly bean system, but it does use a slightly different UI from Sony L36h upgraded to Android 4.2. Of course, the difference between the two is not very huge. At least as far as the main interface and the unlocking interface are concerned, we have not found any difference in the operation mode. At most, the buttons that enter the application interface are designed differently.

The theme of Sony L39h (left) has changed a lot from Sony L36h.

  Like the Sony L36h, the Sony L39h can change the theme and add widgets and applications to the home screen by pressing and holding the home screen. By contrast, we can see that the theme of Sony L39h has changed obviously. At the same time, when we do this operation, the presentation form of the thumbnail of the upper home screen is also different, from white translucent to black translucent, which is more visually recognizable.

    In the application interface and drop-down notification bar, Sony L39h has also changed. In the past, we need to click the button in the interface to call out the menu of unloading and sorting, but in Sony L39h, we just slide the screen to the far left and call out the corresponding menu. When we drop down the notification bar, we can see that the shortcut operation buttons of Sony L39h have been expanded from one row to two rows, but we still don’t support setting the buttons independently.

Sony L39h (left) changed to X-Reality for mobile.

    The change of display interface is also obvious. One of the highlights of Sony L36h is that you can manually adjust the white balance settings, but in Sony L39h, the white balance option has been cancelled. But in contrast, in Sony L39h, the original Bravia Engine 2 was replaced by the latest X-Reality for mobile, and a new backlight optimization mode was added. X-Reality for mobile can make the picture presented to us clearer and more vivid, which can be regarded as another upgrade of Bravia.

    In terms of function, there is not much innovation in this L39h, which continues the characteristics of Sony L36h and the middle school, such as sketch function. On the whole, Sony L36h put all the emphasis on taking pictures. Let’s take a look at how the new camera flagship of this Android platform performs.

Comprehensive evaluation of Sony Xperia Z1 with 20.7 megapixel G lens
Sony L39h, the biggest change is taking pictures.

    Sony L39h has three key words in taking pictures, namely, 1/2.3-inch large Exmor RS layered image sensor, Sony G lens, and mobile BIONZ image processor. So how does Sony explain these three keywords?

    The main camera of Sony L39h has been achieved, and the 1/2.3-inch Exmor RS laminated sensor can capture more scene light and make full use of the powerful function of camera lens to shoot ultra-high resolution images. The sensor has higher sensitivity, which can reduce noise, ensure smooth and clear images, and completely reproduce all wonderful details with higher fidelity. Sony G lens is a unique feature of Sony used in cameras, which has extremely high in-focus imaging quality. In addition to sharpness, it also has excellent light gathering ability. The F2.0 large aperture 27mm wide-angle lens adopted by Sony L39h can perform better in low light and capture more light.

    In addition, in order to get better detail reproduction effect, Sony L39h also uses the powerful algorithm of Sony mobile BIONZ image processor to make the shooting picture more vivid and realistic. Ultra-high pixel resolution, automatic exposure and automatic white balance ensure the accurate presentation of the colors captured by Sony G lens-while achieving brightness balance, the colors are enhanced and reproduced with rich texture layers and layers, and the effect is the same as that seen by the naked eye. The combination of 1/2.3 inch 20.7 megapixel mobile Exmor RS layered sensor and mobile BIONZ image processor can also eliminate noise.

    Finally, a new breakthrough of Sony L39h lies in the zoom of 3x clear image. When shooting at a long distance, the high-resolution sensor and the mobile BIONZ image processor can provide users with an optical zoom of 81mm, bringing the picture closer, and the details are still clear. Of course, as our text shows, it is limited to zoom 0 distortion within 3 times.

Long press shutter continuous shooting needs to be set in advanced automatic mode.

    In fact, the basic camera function of Sony L39h is not much different from that of the past. However, it should be noted that there were various scene modes for us to choose from in Sony in the past. However, in Sony L39h, users can’t manually select the scene mode, but can only automatically identify the most suitable scene mode at present through the "advanced automatic" mode. In addition, the function of continuous shooting requires us to open the option of long-press the shutter button continuous shooting in the setting menu of "Advanced Auto" mode. Frankly speaking, the setting of these small options is actually more complicated than before.

    After reading the basic functions, let’s take a look at the featured functions in L39h. Obviously, the time shift function of Timeshift Burst, the information acquisition function of Info-eye and the shooting function of AR augmented reality are the three most interesting camera functions in Sony L39h. How to play these functions?

Info-eye function in Sony L39h

    The function of Info-eye is very interesting, and we can use it as a new way to get information. Info-eye can shoot landmark buildings, characters, red wine, business cards and other formulated objects. As long as we shoot through the camera viewfinder, we can immediately see the relevant information obtained by networking.

Comprehensive evaluation of Sony Xperia Z1 with 20.7 megapixel G lens
Timeshift Burst function, the user can capture it without fail.

    Timeshift Burst’s time shifting function is actually to help users capture the best photos through ultra-high-speed continuous shooting. When the shutter is pressed, the Timeshift Burst time shift function will completely record 61 images in one second before and after the shutter. After taking pictures, we just need to dial the photos in the turntable and choose the best one to save.

    The fun photo function of AR augmented reality is very suitable for users with children at home, or for multi-party to enliven the atmosphere. Sony L39h provides us with seven interesting AR scenes. When the face is recognized, Sony L39h will automatically add funny accessories such as hats and glasses to the face, and the addition of these AR animations is also very intelligent. When there is a plane in the picture, these animations will be placed on the plane, and there will be no unscientific pictures such as corals floating in the air or mushrooms appearing overhead.

Comprehensive evaluation of Sony Xperia Z1 with 20.7 megapixel G lens
Sony L39h still comes with 9 kinds of filters.

    In the Sony L39h, nine kinds of camera filters used in Sony are retained, so users can take photos of various small and fresh literary styles directly through the camera in their mobile phones according to their own needs.

     After introducing the innovation of L39h camera technology and the breakthrough of camera function, we should also take a look at the photo proofs of Sony L39h. Because Sony L39h is a product that has made a big breakthrough in taking pictures, we also chose the flagship Sony L36h at the beginning of this year for comparison. Although there is a big difference in the number of pixels between the two, it is really unfair to compare them, but it is also part of Sony L39h’s photo improvement. We will present the proofs in outdoor, indoor, macro and low light, and the AR proofs of Sony L39h will also be attached.

    The outdoor proofs in the daytime are divided into two situations, one is that there is enough light in the sun, and the other is that the shade is relatively backlit. Sony L39h’s color in the sample under the shade of the tree is more realistic than Bisogni L36h’s, and the degree of protection is higher. However, in a sunny environment, perhaps due to the large amount of light entering Sony L39h, the overall color tone is a little whiter than Sony L36h, but at the same time, the details of trees in the distance are richer.

    We took a lot of indoor proofs, and chose the shopping mall as an environment with complicated light for comparison. We can clearly see that Sony L39h’s ability to aggregate light is much better than that of Bisogni L36h. At the same time, Sony L36h appeared obvious color cast when shooting indoors, while Sony L39h restored the real color in place and controlled the noise well.

    Next, we will challenge the low light and macro of L39h and the effect of AR photography. In low light, we chose indoor and outdoor situations. Strictly speaking, the two macro photos were also taken in low light environment.

Sony L36h Weak Light Proof (Indoor)

    Sony L39h did a good job in the part of taking pictures in low light. First of all, while improving the brightness, the color is more natural, and there is no loss of some details. The picture of the building was taken at sunset in the evening, and both Sony L39h and Sony L36h automatically improved the overall brightness of the picture. However, we can find that the billboard in the Sony L36h sample has obvious details missing, and the building itself also appears white and the contrast is not strong enough. When shooting at night after the sky is completely dark, although the performance of Sony L36h is still satisfactory, it is obvious that there is a certain gap in saturation compared with Sony L39h, and the color of the picture is not vivid enough. In the last indoor low-light shooting session, the proofs of the two devices have obvious differences in fineness. Because Sony L36h will smear seriously in order to reduce noise when shooting in dark light, the overall picture gives us a little fuzzy feeling.

    In macro aspect, both Sony L39h and the previous Sony L36h have a good performance, and the blur of the background is in place. The only difference between them is that they are both shooting outdoors in the evening, but the brightness of Sony L39h is higher.

Sony L39h AR model proofs

    Finally, let’s look at the photo proofs in AR augmented reality mode. Because the dinosaurs or other animations in the picture are constantly moving, the photos taken by everyone must be different. AR animation is very smart to attach to the ground or desktop, and when taking a portrait in AR mode, hats, glasses, etc. will be added to the corresponding positions and will move with the movement of the portrait. However, if we cover a part of the face with our hands, or shoot the side face, these AR elements will not appear on our face.

    Generally speaking, the camera performance of Sony L39h has been greatly improved compared with Sony L36h, but in the process of actual use, we also found some shortcomings. Sony L39h’s imaging speed is a little slower, so it is easy to take a photo because of hand shaking, which will be more obvious when shooting in low light. In addition, it is AR mode, and the effect of shooting through the main camera in low light environment is not very ideal. We hope that Sony can optimize this in the future.

    Next, let’s look at the multimedia performance of L39h. First of all, in terms of video, it is definitely no problem for Xiaolong 800 to play 1080p video, but some formats that Sony comes with cannot be played, and we need to play them through soft decoding of third-party players.

    Sony L39h, like Sony L36h and Sony L36H we evaluated before, plays mpg with the help of a third-party player. But overall, the mobile phone plays 1080p video quite smoothly, which also provides a solid hardware foundation for Xiaolong 800. Sony L39h’s video player can also set sound effects to bring a better viewing experience.

Only when playing music can it be fixed in the unlocking interface.

    In terms of audio, Sony L39h can play the audio files in m4a, ogg, wav and mp3 formats we tested, but the ape format can only be played with the help of a third-party player. The music player is not much different from the recently upgraded Sony L36h, and just like the Sony L36h, the music player can only be displayed on the unlocking interface when playing music, which means that we can’t directly access the music player from the unlocking interface at ordinary times, but need to unlock it first and then click to enter, which is somewhat inconvenient.

Playing online web videos is quite smooth.

    Perhaps because it is not the final retail version, the application of Sony L39h we evaluated is not very complete. Just for exampleWhen we want to test the online experience, we find that there is no preset in the mobile phone, so we will test it in Sony Select.Sony L39h’s performance in loading web pages, zooming and playing videos is very smooth, which makes it difficult for us to pick out any shortcomings. With enough hardware in place to support it, Sony L39h’s performance is taken for granted.

    Hardware configuration is not the biggest publicity highlight of L39h this time, but in any case, for most users, hardware is always one of the first factors to consider when choosing a product. Sony L39h is equipped with a 1080p display screen, and has chosen the top Opteron 800 processor in Qualcomm at 2.2GHz, supplemented by 2GB RAM and 16GB body storage space, of which the space available for users has reached 11GB. Following the first release of this world’s earliest release, Sony L39h is also the second intelligence equipped with the Opteron 800 processor in Sony products.

    In addition to the advantages of performance and speed, Xiaolong 800 processor also has excellent battery life. You can run multiple applications at the same time, surf the Internet quickly, and play videos smoothly, which are all intuitively reflected in our previous evaluation. In addition, the Snapdragon 800 series MSM8274 quad-core processor with 2.2GHz frequency adopted by Sony L39h is an asynchronous processor, and each core supplies power independently. The battery power will be accurately allocated according to the user’s use needs, thus achieving the effect of saving electricity. In addition, with the STAMINA power-saving mode in Sony L39h, the worry-free use of the whole day under normal intensity is not a problem.

    AnTuTu Runfen recently released the latest version of V4.0, in addition to the previous four test items of CPU, RAM, GPU and IO, this time it also added the user experience rating item. AnTuTu said that "in the traditional test, the performance limit of hardware will be emphasized, but the highest score of the test can not fully reflect the operating efficiency of the system", and AnTuTu thought that "multitasking ability is a very important indicator. The processing efficiency of multi-core and multi-task will directly affect the fluency of the whole system. " Therefore, AnTuTu V4.0 adds MultiTask Multithread Performance Test, and quantifies the optimization degree of UI/ROM through Dalvik. At the same time, AnTuTu V4.0 also provides 3D performance test in ES 3.0 environment, so the AnTuTu running score in this version is not comparable to that in the previous evaluation, and we can only compare it through the popular model rankings given by AnTuTu for the time being. Obviously, Sony L39h, which runs at 30444, does have the superiority of the flagship model. Compared with Sony L36h, the score is improved obviously.

Tens of thousands of people rushed to the front line to protect the "lifeline" of the city.

Water workers in protective clothing enter the community service city water group for the picture.

Water workers in protective clothing enter the community service city water group for the picture.

  Every day, in the "Urban Operation Support Work" WeChat group composed of the key office of Wuhan Municipal Government and urban water, electricity, gas, fuel, communication, transportation, traffic control and other units, all kinds of coordination work are meticulous. "Guarantee the lifeline of the city without any mistakes!" Focus on overall planning, water affairs, traffic control and other departments closely cooperate, sewage treatment chemicals, oil products, disinfectant … … All kinds of transport vehicles are constantly gathering in Wuhan.

  Since the temporary closure of Wuhan’s passage from Han on January 23 and the suspension of traffic operations, as of February 9, more than 9 million citizens in Han have spent 18 days smoothly. As the lifeline and ballast stone of the city, water, electricity, gas, oil and communication are well supplied and stable and orderly. Behind this is the joint efforts of more than 20,000 security personnel every day.

  On February 8th, the Urban Operation Group of COVID-19 City’s Prevention and Control Headquarters introduced that in order to ensure that the relevant key parts and the people of the city have no worries during the epidemic prevention and control period, there are 24,000 people working in the urban operation sections such as water supply, power supply, gas use, oil use and communication every day, among whom 14,000 people are on the front line. They overcame many difficulties and tried their best to ensure the normal operation of the city even when their own protective materials were in short supply.

  Arrears are not stopped, and the water supply hotline serves 24 hours.

  According to the Municipal Water Affairs Bureau, as of February 5, the overall water supply situation in the city is stable and orderly. The average daily water supply in the city is about 4 million tons, and the water supply capacity in the city is 6.3 million tons/day, which can guarantee the daily water supply and the water quality meets the national health standards. In order to prevent the inconvenience of water use caused by arrears, water supply enterprises have also introduced measures to facilitate the non-stop water supply during the epidemic.

  The relevant person in charge of the Municipal Water Affairs Bureau said, "We give full play to the advantages of smart water affairs and use scientific and technological means to coordinate the dispatching of water pressure and water quantity." With the help of big data, cloud computing and other means, the water pressure in the city is sufficient and the pipe network is safe to operate.

  Regarding the water quality problems during the epidemic prevention and control period that citizens are concerned about, the city has continuously monitored the water quality changes by encrypting the frequency of water quality testing for factory water, pipe network water and peripheral water to ensure water quality safety.

  On February 2nd, there was no water in Mr Tian’s home in Qili New Village, Hanyang. Mr. Tian is a highly suspected COVID-19 patient and is isolated at home. Liuyong, deputy director of Hanyang Pipeline Institute of the Municipal Water Group, reminded everyone to wear protective clothing: "The water supply guarantee is not divided into objects, and the danger is also on." After on-site maintenance, the water problem in Mr. Tian’s home was solved.

  Since January 23, in order to reduce the probability of residents entering and leaving crowded places, the city has suspended the door-to-door copying business and temporarily closed the business hall. At the same time, keep the online channels open and the water supply hotline service 24 hours a day.

  There is no power outage due to arrears, and workers patrol dozens of kilometers of cable lines every day.

  From January 24th to February 6th, State Grid Wuhan Power Supply Company dispatched a total of 28,658 personnel and 4,278 vehicles for epidemic prevention and power supply protection. At present, the city’s power supply is all normal.

  During the epidemic prevention period, Wuhan Power Supply Company took measures to ensure the electricity consumption of people’s livelihood by paying arrears to residents. As of 24: 00 on January 28th, about 490,000 households in Wuhan were in arrears without power failure.

  After the city’s access roads were closed, Yu Nianchun, a group of young employees of Wuhan Power Supply Company’s cable inspection team, led by Sun Changqun, the squad leader, drove the "yellow pickup truck" more frequently to escort the main cable line of Wuhan Power Grid.

  Yu Nianchun said: "The situation is special now. There are few people staying in Wuhan. The unit is in short supply. If I can go, I will come." As promised, from the first day, he visited dozens of kilometers of cable lines every day, measured the temperature and circulation of more than a dozen cable terminals and intermediate joints, and evaluated the state through the data and made records.

  Zhao Bin, an ordinary electric power repairman in Wuhan, said, "In this special period, we must stick to our posts and deal with the emergency repair tasks that appear at any time. One night, I received a rush repair task, and the user lost power due to the failure of high-voltage cable. We started at 8 o’clock in the evening and didn’t return to the company until 1 o’clock in the morning. "

  There is no gap in the air source, so the medical staff can take a hot bath with ventilation on the same day.

  Since January 23, all employees of Wuhan gas industry have entered a "wartime state", and more than 2,000 employees of 88 gas companies have adhered to the front line to ensure that citizens use gas for their lives, medical institutions supply gas, and hospital construction projects are ventilated on time.

  The Municipal Urban Management Law Enforcement Committee and the Municipal Gas Management Office introduced that during this period, the urban management department focused on supervising gas enterprises to implement the safe and stable gas supply of medical institutions.

  From the beginning of the Lunar New Year, Zheng Hui, a line inspector of the Municipal Natural Gas Company, has been living in Changqing Management Station of Hankou Pipeline Institute. He patrols more than 60 kilometers every day, increasing the number and intensity of inspections on the pipe network around Jinyintan Hospital to ensure the safe operation of the pipe network and the safe use of gas by more than 180,000 households in the jurisdiction.

  On February 1st, Ziyang Lake Hotel, near Hubei Provincial People’s Hospital, was designated as the accommodation for medical staff in the hospital, and it was necessary to connect natural gas as soon as possible. WISCO Jiangnan China Gas Company acted quickly. After 8 hours of intense operation, natural gas was turned on, 3 hours earlier than expected, and the medical staff who stayed that night took a hot bath.

  According to statistics, from January 24 to February 7, the city supplied an average of more than 8 million cubic meters of natural gas every day; Accumulated supply of liquefied petroleum gas is about 250 tons; Vehicle natural gas is sold for about 300,000 cubic meters, with stable inventory and no shortage of gas source for the time being.

  Engineers crossed the quarantine area and installed video phones for the hospital.

  From February 6th to 7th, the maintenance engineers of Wuhan Branch of China Telecom fought all night in the front line of epidemic prevention communication support, and installed video phones for 16 designated hospitals.

  At two o’clock in the morning on the 6 th, the company was ordered to start the video phone installation work urgently. The company originally had more than 30 employees, but some of them went back to their hometown in advance on holiday, and some of them were isolated because of contact with suspected patients, and only 16 people could be called. Everyone knows the danger of more than a dozen circuits passing through the hospital isolation zone, but no one flinched. After nearly 30 hours of intense construction, almost everyone did not have a decent meal, but no one complained.

  Wuhan Municipal Communications Administration, together with the municipal economic and information department, will co-ordinate and organize the city’s communications enterprises to fight hard and overcome difficulties. There are countless such examples.

  At noon on February 1st, Huangpi Branch of Wuhan Telecom received a call from a user. A user in Outang Village of Changling was trapped in the bay because of the epidemic. Three children at home had to take online classes, and there was no network at home. I hope that Telecom can install the network at home.

  Due to the severe epidemic situation, rural roads were blocked, so Gao Hongli, a salesperson of Changling Branch of huangpi district Branch, and Huang Jinsong, a maintenance worker, rode motorcycles to the users’ homes against the cold wind and immediately wired them. It took only four hours from receiving orders to accepting and installing machines.

  According to the requirements of epidemic prevention headquarters, Wuhan Telecom opened video conferencing service for 50 key hospitals and isolated wards in the city. Open fixed line and broadband for a number of medical isolation points. Wuhan Mobile has completed the network testing and optimization of 49 isolation points, and Wuhan Unicom has implemented a number of site resource expansion.

  The fuel supply in the whole city is guaranteed if the oil is continuously supplied and the station does not close.

  During the anti-epidemic period, Sinopec Caidian Zhiyin Station and Jiangxia Wunan Gas Station provided 120 ambulances for all patients in the city with free refueling and free meals.

  More than 100 negative-pressure ambulances donated by the whole country to Wuhan arrived in Han late at night on February 5, and Sinopec Hanyang Nangang Gas Station provided a venue for vehicle handover, providing free refueling for all ambulances and free meals for drivers.

  At the beginning of the Wuhan epidemic, the Municipal Bureau of Commerce set up a command group for urban gasoline (diesel) oil supply, organized oil companies to start emergency plans, monitored the operation of the refined oil market every day, and coordinated and solved the difficulties and problems in oil supply, material transportation, employee commuting, and insufficient protective equipment at gas stations.

  On New Year’s Eve, employees of PetroChina Wuhan Sales Branch received a proposal to fight against COVID-19 sent by the company. In less than eight hours, a total of 100 party member and two party activists volunteered to fight.

  Li Shengxiong, an employee of Huangjinkou Gas Station of Wuhan Hanyang Branch of Sinopec, rode more than 20 kilometers from home to be on duty in order to ensure the duty on the second and third days of the New Year’s Day.

  Since the outbreak, nearly 410 gas stations of PetroChina, Sinopec, Total and large-scale private oil companies have insisted on normal business, and 92#, 95# and 98# gasoline and diesel are complete, ensuring that "the oil is constantly supplied and the station does not close" and doing its best to protect the needs of citizens and epidemic prevention units.

Spring Festival: a young and ancient festival

  Author: Zhang Bo (researcher, Institute of Beijing Studies, Beijing Union University)

  "Hundred years first, four seasons spring first." Spring Festival is a traditional New Year in Chinese.

  The Spring Festival is the original culture of the Chinese nation, but it is not the exclusive culture of the Chinese nation. As early as the Sui and Tang Dynasties, the Spring Festival had spread to East Asian countries. In recent years, with the increasing spread and influence of Chinese civilization, people in more countries and regions have fallen in love with the Spring Festival, celebrated it, and even listed it as their own legal holiday. On December 22nd, 2023, the 78th UN General Assembly adopted a resolution by consensus, which designated the Spring Festival (Lunar New Year) as a UN holiday, and the Year of China went further to the world. This not only makes Chinese excellent traditional culture better benefit mankind, but also provides stronger support and motivation for the continuation of the Spring Festival.

   1. From "Lunar New Year’s Day" to "Spring Festival"

  At the beginning of the founding of the Republic of China in 1912, the Gregorian calendar era was adopted in order to connect with the west. Since then, there have been two New Year phenomena in China. January 1st of the Gregorian calendar is the New Year, and the first day of the first lunar month is also the New Year. In 1914, Yuan Shikai’s government made a put in order of traditional festivals, and renamed the Lunar New Year’s Day, Dragon Boat Festival, Mid-Autumn Festival and Winter Solstice Festival as Spring Festival, Summer Festival, Autumn Festival and Winter Festival respectively, thus forming a complete festival sequence of spring, summer, autumn and winter. For more than 100 years, four festivals have been passed down, but among the four new festival names, only "Spring Festival" has been recognized by the people and become the standard name of the Lunar New Year.

  In different contexts, the Spring Festival often has different meanings. Sometimes it only refers to the first day of the first month of the lunar calendar, which marks the coming of the new year. In history, there are many sayings such as "the first month of the first month", "Zhengdan", "Zhengri", "Yuanzheng", "New Year’s Day", "Sanyuan", "Zhengchao" and "Yuanchen". But more often, the Spring Festival is equivalent to what we often call "Chinese New Year" and "Chinese New Year", which is the sum of a series of festivals with the year-end and the beginning of the year as the core and around the annual cycle. "One night is even two years old, and the five are divided into two years." Chinese New Year takes New Year’s Eve as the dividing line, including year-end and early year. The year-end activities take the busy year as the theme, and the early year as the theme, which mainly includes the New Year, New Year’s Eve, New Year’s Day (the first day of the first month), Lantern Festival, etc. It is a happy and peaceful festive day to bid farewell to the old and welcome the new.

   2. Coming from the depths of history

  As the first year of the year, the origin of the Spring Festival is closely related to the formation of the concept of "year", and the formation of the concept of "year" is inseparable from the progress of the calendar.

  As a method of arranging years, months and days, there are three kinds of calendars in astronomical sense, namely, solar calendar, lunar calendar and yin-yang calendar. To put it simply, the solar calendar takes the tropic year (the period of the earth’s revolution around the sun, and the modern measured value is about 365.2422 days) as the basic period, with 365 days in a normal year and 366 days in a leap year, such as the current Gregorian calendar. The lunar calendar is based on the first lunar month (the cycle of moon phases changing), and 12 months make up a year, which is 354 days or 355 days. Now Arab countries use the lunar calendar. In China, as early as the Xia, Shang and Zhou dynasties, a combined calendar of yin and yang was formed, which took into account the tropic year and the first lunar month. According to the Book of Yao Dian in Shangshu, Emperor Yao appointed wise men from the Xihe and Heshi families to observe the movement of the sun, the moon and the stars, master its laws, and teach the people the time. "There are six days in three hundred and sixty years, and the leap month will set the age at four o’clock." It shows that at that time, it has been able to determine that a year is 366 days, and it can adjust Yin and Yang by setting leap months, so that each month conforms to the changes of the moon’s profit and loss, and each year conforms to the changes of spring, summer, autumn and winter.

  Before Xia, Shang and Zhou Dynasties, "Nian" had different names. "Er Ya Shi Tian" records: "Xia Yue Sui, Shang Yue Si, Zhou Yue Nian, Tang Yu Yue Zai." Among them, the original meaning of "Nian" is the bumper harvest of crops, and Oracle Bone Inscriptions’s word "Nian" is the pictograph of people carrying grain. Shuowen says, "Year is ripe." When the grain is ripe once a year, people take the period of grain maturity as a time unit, which is called year. With the concept of "year", we can also determine the beginning of the year.

  The ancients in China attached great importance to the beginning of time, and thought it was of fundamental significance to the construction of order. As the saying goes, "The beginning is the end, but the order is not perfect". Xia, Shang and Zhou Dynasties took the month of establishing Yin (January in the summer calendar), the month of establishing ugliness (December in the summer calendar) and the month of establishing children (November in the summer calendar) as their own "year beginning", which laid a time foundation for the formation of Chinese New Year customs. However, due to the lack of documentary records, it is difficult for us to know exactly how people celebrated the New Year before Xia and Shang Dynasties. By the Zhou Dynasty, rich Chinese New Year customs had been formed. The people of Zhou Dynasty began with November in the summer calendar, and the year-end sacrifice, celebration and auspicious activities in the first month constituted the basic contents of the New Year at that time.

  Year-end sacrifice is a series of ceremonies including wax sacrifice and La Worship, which not only rewards various gods, but also misses and gives thanks to ancestors.

  About the wax sacrifice, there is a detailed account in the Book of Rites. The purpose of wax sacrifice is mainly to repay the blessing of the gods. The so-called "ancient gentleman will repay it". The objects of sacrifice mainly include: Xian Si (Shennong), Si Si (Hou Ji), Baigu (the seeds of Baigu), Nong (the agricultural official who manages farming and teaches agricultural technology), postal list (the temporary place where the farmland official who supervises farming lives and field signs), animals (such as cats and tigers), and Fang (the dam). Wax sacrifice occupied a very important position in people’s life in the pre-Qin period. The dialogue between Confucius and his disciple Zi Gong recorded in the Book of Rites Miscellaneous Notes can reflect this point: "Zi Gong is concerned with wax, and Confucius said,’ Is it a pleasure to give?’ Right:’ If all the people in a country are crazy, they will be given pleasure in the unknown.’ Although Zigong could not understand the joy of wax, the sight of "people in a country are crazy" is enough to show the great significance of wax sacrifice to the people.

  La Worship is also a year-end sacrifice, the object of which is the ancestor and the God of Five Sacrifices. The Five Sacrifices refer to doors, households, wells, stoves, and strollers. People worship them and thank them for providing important guarantees for people’s daily lives. The holding of wax festival and La Worship marked the end of agricultural production, which is of great significance to mark the transformation of life at the age of 20. After that, people will hold feasts to celebrate. What is depicted between the lines in the last chapter of The Book of Songs in July is the scene of feasting and celebrating, lively and peaceful, and happy New Year.

  In the Zhou Dynasty, New Year’s Day was often called "the auspicious day of the first month", and a grand ceremony was held in the court, in which hundreds of officials of governors appeared before the Emperor, and the Emperor held a banquet to commend and reward their contributions.

  The auspicious day of the first month is also a day to announce government decrees and laws and educate the people. The government will hang all kinds of policies and laws that need the people to know for 10 days above Wei (a tall building outside the palace gate of the emperor and vassal) for the people to see. Local officials spread all kinds of decrees to the grass-roots level of society so that everyone can check them against each other. At the beginning of the year, the Zhou Dynasty took advantage of the opportunity of the beginning of the new year and the newer years to issue decrees and promote enlightenment to ensure the orderly operation of the whole society in the new year.

  Undoubtedly, the custom of Chinese New Year was formed in the Zhou Dynasty, and the Spring Festival has experienced at least 3,000 years of life. In 104 BC, Emperor Wu of the Han Dynasty promulgated the taichu calendar, and re-established the month of the founding of Yin (January in the summer calendar) as the first month. As a result, January 1st in the summer calendar became the first day of the year, and the year-end year-end year-end activities were moved to a new time accordingly. After more than two thousand years, the Chinese New Year basically started on January 1st in the summer calendar, which is still the case today.

   3. Why did it last for thousands of years?

  14,500 years ago, Zong Yi, a man from the Southern Dynasty, described the custom activities of the Spring Festival at that time in the Chronicle of Jingchu: "The first day of the first month is the day of three yuan, and the Historical Records also call it the end of the month. When the cock crows, firecrackers and grass are set off before the court, so as to rid the mountain of evil spirits. All ages know that they are dressed in clothes, and they pay tribute to each other. Pepper and cypress wine and peach soup. Tu Su wine, gum tooth. Play a five-spice plate. Apply it to the powder, but take the ghost pill. One chicken each. Making a peach board is called fairy wood. Every time you drink alcohol, you start from an early age. " In this paper, it was mentioned that drinking pepper and cypress wine, drinking peach soup, drinking Tu Su wine, chewing gum, taking five spicy dishes, taking ghost pills and hanging mahogany boards on the door were all the most popular custom activities at that time, but they were not seen in today’s Spring Festival life. As for firecrackers, although they are still in use now, their shapes are quite different, and the purpose of setting off firecrackers is no longer "to repel evil spirits." This obvious difference between ancient and modern times clearly reveals the changes of the Spring Festival.

  In fact, as long as we look at the literature records of different historical periods, it is not difficult to find that the Spring Festival has been changing. Not only the customs of festivals are changing, but also the duration, broadcasting space and name of festivals are changing greatly. However, despite all the changes, the Spring Festival is not fade away. In fact, the Spring Festival has always maintained a strong vitality. It spans time and space, from the pre-Qin period to the present, and has become a long-lasting and endless cultural tradition.

  There are profound social, political and cultural reasons for the endless Spring Festival.

  First, the Spring Festival is rooted in the endless fertile soil of Chinese civilization, which is the original culture of the Chinese nation. The Chinese civilization, which has lasted for 5,000 years and has developed to this day in a national form, is the foundation for the continued existence of the Spring Festival. If Chinese civilization is compared to a leafy tree, then the Spring Festival is a beautiful flower bred by this tree. Trees grow vigorously and flowers bloom every year.

  Second, the long-term stability of the calendar and the establishment of the holiday system provide a guarantee for the inheritance of the Spring Festival. Festivals exist depending on the calendar. As mentioned earlier, three generations ago, China had formed a combined calendar of Yin and Yang, which took into account the tropic year and the first lunar month. After that, although the calendar calculation became more and more accurate, the principle of compiling the calendar was stable for a long time, which also provided conditions for the continued existence of the Spring Festival. In addition, the holiday system has also played a positive role. During the Han Dynasty, China has established a complete vacation system, giving all kinds of legal holidays to officials of all sizes, and holiday saving is an important part of it. During the Tang and Song Dynasties, the holiday system was more complete, and the Chinese New Year became the longest holiday. Both Jin and Yuan dynasties followed the holiday system of the Central Plains Dynasty, with an average annual holiday of 3 days. The Qing Dynasty paid more attention to the Chinese New Year, marked by seals and seals, and the holiday lasted nearly one month. The implementation of the holiday system not only gives officials time to celebrate the New Year, but also strengthens the official recognition of this festival and guides all members of society to inherit and practice the festival.

  Third, the characteristics of sharing between the government and the people have created a huge group of Spring Festival inheritors. A large number of traditional festivals in China are not simply folk festivals, but have distinctive characteristics shared by the government and the people, especially during the New Year. Sharing between the government and the people does not only mean that the ruling class will personally participate in various customs activities of the festival like ordinary people; More importantly, the government will also hold various activities during the festival, thus making the festival an important time and space for national governance. The sharing between the government and the people in the New Year was formed as early as the Zhou Dynasty, and the Yuan Dynasty Meeting was a typical performance. Since the Qin and Han Dynasties, the Yuan Dynasty has been passed down from generation to generation. At that time, on the one hand, officials from all over the country, civil and military officials, royalty and relatives in Beijing, as well as foreign envoys, will greet the emperor and present gifts; On the other hand, the emperor rewarded bureaucratic ministers by giving things and feasts, so as to establish the legitimacy of political power, build a harmonious and warm relationship between monarch and minister, and safeguard the unity of the country. The survival of the festival depends on someone celebrating the festival. The more people celebrate the festival, the stronger the vitality of the festival. The Spring Festival has always been a festival shared by the government and the people, and there are many people who celebrate it. Various etiquette and custom activities bear rich cultural connotations and endow the Spring Festival with multiple functions. After a long period of accumulation, the Spring Festival has formed a very rich custom activities, such as offering sacrifices to the stove, ancestor worship, sweeping the house, busy New Year, New Year greetings, putting up Spring Festival couplets, wearing new clothes, setting off firecrackers, visiting temple fairs, enjoying flower lanterns, walking on stilts, boating, feasting and partying, and dancing lions and dragons. Among them, there are exquisite manners, food and clothing, social interaction and entertainment activities.All these bear the values and ideal demands of the Chinese nation, such as reverence for nature, respect for ancestors, gratitude and gratitude, family reunion, social harmony and harmony in the world. By participating in it, people coordinate the relationship between heaven and man, renew social relations, and adjust the individual’s physical and mental relations, so that the Spring Festival has important functions such as strengthening the emotional connection between individuals and their families, hometowns, places and countries, enhancing community awareness and promoting social harmony, thus being deeply embedded in the social structure and becoming a cultural tradition that members of society cannot abandon.

  Fourth, the constantly updated, open and inclusive Spring Festival culture continues to empower the inheritance of the Spring Festival. The Spring Festival is not a rigid and closed cultural system, it changes with time and adapts to local conditions. Throughout history, people in different dynasties always developed custom activities in line with the characteristics of their own times. People in the southern dynasties burned firecrackers to avoid evil spirits, while contemporary people used gunpowder firecrackers to express their joy and blessing for the arrival of the new year; In the 1980s, people liked to send New Year cards, but today, it is fashionable for people to pay New Year greetings through WeChat. Looking at the whole country, people in different places always make full use of their natural environment and human conditions to create custom activities with local characteristics by visiting temple fairs in Beijing, flower markets in Guangzhou and flower lanterns in Zigong, and making cakes in jiaozi in the north and in the south.

  Prosperous for the New Year. Spring Festival culture contains the ideal of human common life, such as material abundance, social harmony and spiritual abundance, and carries the common values of family harmony, social tolerance and harmonious coexistence between man and nature, which is the fundamental reason why it can go to the world. Going to the world, the Spring Festival is bound to inherit and develop in cultural exchanges and mutual learning.

Party member Zhan Wen, an outstanding Communist of Guangdong Province: Being the "principal’s mother" of Nayong children in Guizhou Province

  "Principal, mom, when I grow up, I want to be an excellent Communist party member like you." On the evening of July 1st, Zhan Wen, principal of Chebei Primary School in Tianhe District, Guangzhou and lifelong honorary principal of Nayong Tianhe Experimental School in Bijie City, Guizhou Province, received the news of Zhang Ping, a student of Nayong, and she immediately replied, "Baby, I am so proud of you!"

  "Principal’s mother" is the nickname for Zhan Wen by Nayong students. In May 2018, Zhan Wen was selected to teach in Nayong, during which she took the initiative to apply for extending the teaching time from three months to three years. A few days ago, Zhan Wen was awarded the outstanding Communist party member of Guangdong Province.

  "After retirement, I want to go back to Nayong Tianhe Experimental School and build the school better." Zhan Wen said that she wants to bring more love to Nayong so that children can get a better education.

  From "female security guard" to "principal and mother"

  On May 17, 2018, Zhan Wen embarked on a journey of teaching and arrived at the No.1 Primary School in Nayong County. Looking at crowded classrooms and timid children, Zhan Wen has mixed feelings-how to improve the hardware? How to close the distance with children?

  Zhan Wen learned that many children are left-behind children and are more introverted. She offered to go to the school first, hoping to get familiar with the children as soon as possible. At 7: 30 every morning, Zhan Wen appeared at the school gate on time and gave a high-five hug to the students who arrived at school. "Hello, good morning!" "

  A child said that there was an enthusiastic "female security guard" at the school. In the louder and louder greetings, the children became more and more sunny. They lined up with high-fives and took the initiative to say hello.

  On one occasion, Zhan Wen couldn’t get to school on time because of physical discomfort. Later, a classmate put a letter into her hand, which contained such a sentence: "I have a good teacher, don’t hurt her in time!" " Zhan Wen’s eyes are wet when reading the letter.

  Later, the local government introduced various resources to participate in the assistance work, and the appearance of the first primary school in Nayong County changed greatly soon. The school built three new playgrounds, and the number of students in each class was controlled within 55.

  Zhan Wen made teaching AIDS, taught children to draw mind maps, write math diary, and make mathematical manuscripts, which made abstract knowledge concrete, and children became more and more interested in mathematics. Zhan Wen has gradually become the "principal and mother" of children. After the expiration of the three-month teaching period, Zhan Wen applied to extend the teaching time.

  Let more teachers and children "dare to dream"

  Returning to Nayong again, Zhan Wen’s role has also changed from the vice president of Nayong County No.1 Primary School to the member of the party group and deputy director of Nayong County Education Science and Technology Bureau. "Poverty alleviation first helps wisdom." After taking up his new post, Zhan Wen spent more than a year traveling around more than 500 schools in Nayong County, discussing the school-running concept and orientation with the principal, and recording the needs of the school.

  She built nine "dream classrooms" worth 1.8 million yuan for Nayong, so that more teachers and children have the confidence to "dare to dream". She connected caring people from all walks of life and won various material donations for dozens of weak schools in Nayong County.

  "In addition to the improvement of hardware, it is more important to improve the level of local teachers and improve the soft power of education." Zhan Wen said that, therefore, she organized 56 trainings such as "Spark Plan" and "Positive Education", and trained more than 9,000 teachers to help teachers broaden their horizons.

  In 2019, Tianhe District invested 42.5 million yuan to build Nayong Tianhe Experimental School. In December of the same year, Zhan Wen served as the first principal of Nayong Tianhe Experimental School, and took on the heavy responsibility of education for 1,600 students who moved out of poverty. Zhan Wen first contacted a number of enterprises to donate equipment and materials for the school, and won a love donation of more than 2 million yuan.

  In order to expand the coverage of quality education resources, Zhan Wen took Nayong Tianhe Experimental School as the base, and set up seven schools and a kindergarten in Nayong County, including the No.1 Primary School, into a "7+1 pigeon blossom" learning community with resource sharing, professional mutual promotion and group development.

  After three years of teaching, Zhan Wen passed on the love from Guangzhou to the children in Nayong, leaving Nayong with a model school for ex situ poverty alleviation and relocation, 118 principals trained by Zhan Wenming’s principal pilot studio, a group of teachers with dreams, and the enterprising spirit and hard work of teachers in party member, Guangzhou.
