Text/Figure Yangcheng Evening News reporter Zhang Hua correspondent Wang Shuhua Liu Qisha

It’s too difficult for children this year. Mycoplasma pneumonia hasn’t gone yet, and the flu is coming again. Some netizens complained: "When I went out in the morning, I started to have a fever and feel unwell in the afternoon, and I was infected with the flu, and the onset was quite fast." What are the symptoms of being infected with influenza virus? What medicine should I take? What situation needs to go to the hospital for treatment? The reporter interviewed relevant experts to understand the incidence of influenza and asked them to give corresponding countermeasures.

Emergency use of antiviral drugs within 48 hours of infection.

Influenza virus is mainly spread by respiratory droplets such as sneezing and coughing. Influenza spreads strongly and quickly, and people are generally susceptible, and the risk of infection in children is higher.

"On the first day of infection with the flu virus, the body temperature will rise rapidly, and the muscles of the whole body will be sore, tired and have a headache." Mai Huachao, an attending physician in the Department of Internal Medicine of Guangdong Maternal and Child Health Hospital, said, "The antiviral drug oseltamivir can be used under the guidance of a doctor. It is prime time to use it within 48 hours, which can shorten the course of disease and prevent the occurrence of severe diseases."

With the prevalence of various pathogens in the lower respiratory tract, Cen Zhenghui, deputy chief physician of Pediatrics of the Eighth Hospital affiliated to Guangzhou Medical University, pointed out that the general symptoms of influenza patients are more severe, with high fever obvious in the early stage of the disease, atypical respiratory symptoms, accompanied by fatigue, headache, muscle aches and other manifestations. Patients infected with mycoplasma pneumoniae, unlike influenza, are accompanied by typical symptoms of dry cough in addition to fever. In addition, influenza antigen, mycoplasma pneumoniae serum antibody detection, nucleic acid detection and other tests can help doctors make identification and diagnosis.

If the fever persists for more than 3 days or the cough is severe, you need to see a doctor.

On the second or third day of influenza infection, the immune cells in the body fight the virus with all their strength, and the human body may have repeated symptoms such as fever, headache, sore throat and runny nose. Mai Huachao suggested that at this time, you should rest at home and drink plenty of water to give your body the energy to fight the virus.

Generally, on the 4th day after infection, the body temperature gradually returns to normal, and symptoms such as sore throat, headache and runny nose begin to ease, but the cough will get worse. Mai Huachao pointed out: "When infants, especially those within three months, continue to have high fever for more than three days or cough is serious enough to affect rest, it is recommended to seek medical advice immediately."

After the fever has gone down, quite a few children will have cough symptoms. Mai Huachao said that if you have a dry cough, you can take some cough medicine. If you have a serious cough with phlegm, or have fever symptoms, you should seek medical advice in time. Most symptoms of influenza will be relieved within 3-7 days, but cough and physical recovery often take more than 1-2 weeks.

You can still get the flu vaccine after you get the flu.

Both influenza and mycoplasma pneumoniae can cause pneumonia. Cen Zhenghui pointed out that if the child has a fever for more than 3-5 days repeatedly, the high fever does not go away, or there is a severe cough, the doctor auscultates the rales in the lungs, and the chest film and other imaging findings suggest that the lungs are oozing, which may be pneumonia. The specific situation needs the doctor’s judgment.

Is it necessary to get a flu vaccine after being infected with the flu? Experts say that after the flu patients are cured, it is still necessary to vaccinate against different types of influenza virus infection. Although the protection of vaccine against influenza virus can not reach 100%, it can effectively reduce infection symptoms and improve recovery speed after vaccination. It is recommended to vaccinate after the fever is gone and the flu symptoms are basically relieved.

Hu Dandan, director of vaccination clinic for people with special needs in Guangdong Province of Guangzhou Women and Children Medical Center, said that usually, after 2-4 weeks of influenza vaccination, antibodies with protective level can be produced. Therefore, vaccination can have a protective effect when the peak of influenza comes in winter, and people aged 6 months and above can be vaccinated without vaccination contraindications.

1905 movie network feature "With us around, the remote water supply can’t be cut off." In the movie, the firefighter Xu Xiaobin, who plays the role, jumps into the sea full of oil and flames in order to clean the water pump.

He worked hard to repair, and the final image of his unfortunate sacrifice was vivid and heroic in the lens of the underwater photographer, causing many viewers to cry.

In the movie, the "Expendables" attacked Jingzhou City by water, and the surging light and shadow added another "color" to the black and white ink painting.　

Here, the photographer and the eldest brother soaked in the biting cold water for several hours before completing the drama of diving in the ice cave. The underwater world in the lens is quiet and beautiful, which is fascinating.

How did the amazing underwater shots in the movie, either thrilling or beautiful, work, and how did this special group of underwater photographers, little known to audiences, work?

In this issue of "Behind the Scenes", let’s follow Sun Xun, a well-known domestic underwater photographer who has been in charge of films such as "Shadow", "Kung Fu Yoga" and "Hero of Fire", into the "underwater mystery" behind the lens.

　01. Every shot is a story

After seven years of formal employment, he was responsible for the underwater shooting of countless movies, TV series, documentaries and advertisements. "Heroes of Fire" has always been fresh in Sun Xun’s memory. Since the film is set in the context of an oil pipeline explosion, there must be oil stains, garbage and flames in the seawater. In order to realistically restore the effect of seawater, the art and props team "mixed" pieces of sticky oil stains with starch and paint, and also put in fresh scallops, oysters and other kinds of seafood. The flames are also real burning, which also poses a big challenge to the underwater photography team.

"The camera, the diving equipment, and the face are all covered in a layer of black oil, just like a miner. After shooting for two days, the seafood was soaked for two days, just like a pot of seafood soup, and finally the whole equipment had to be cleaned. But the props team really bothered to have the final real effect." Sun Xun said. At the "Fire Hero" press conference, recalling the shooting experience, Ou Hao said that he almost drowned and experienced a terrifying moment. In the movie, he was shown with a rope tied around his waist, but in the actual shooting, after going into the water, the person kept floating up, and he could only tie the rope to his feet to let people pull him underwater. In addition, shooting outdoors in winter was very physically exhausted, and he could not advance or retreat for a time. "Even now I think about it, I am still a little afraid."

Sun Xun also praised Ou Hao’s contribution: "The actors are very hard-working, and the director and staff are sparing no effort to recreate the tension at that time… China lacks such a film, and we feel honored to be able to participate in the shooting of such a key scene." If the key word of "Hero of Fire" is "bitter", the largest film that Sun Xun has participated in "water drama" is the crime film "Involved in the Sea of Anger" that will be released in the summer. In order to show the human entanglement in extreme environments, there is a long sea shooting in the film, and even Huang Bo, who has excellent water quality, calls it "the most tiring in history".

Sun Xun also felt the same way, "I first shot in the open sea, the sea was very windy, and I was seasick and vomited, which is also an embarrassing thing for me as an underwater photographer. Then I shot a big play in the water shed. Teacher Huang Bo is famous for his water quality, and the completion is very high. He also cooperates well with Teacher Zhou Xun. In addition, the underwater is a dual-camera shooting, and there is a scene of escape in the car. I am looking forward to the effect of the film." Underwater shooting can be both exciting and beautiful and romantic, and the starring literary film shows this.

"Although the film was not very difficult, the shot was very beautiful. At that time, it was Yu Feihong’s inner scene. The beauty of the underwater shot and the mood of the actors fit perfectly. It had the temperament of an Asian literary film. It was the most satisfactory scene from the creator’s point of view," Sun Xun said.

02. Tired and happy

Sun Xun studied engineering at university, but chose the translation industry for his work. When he worked as a translator for a film crew, he began to get involved in photography because of his interest. It can be said that his career has been challenging himself.

In the process of engaging in film and television photography, Sun Xun found that underwater photography teams in China are very scarce. "The film industry is developing rapidly, and industrialization is becoming more and more complex. At that time, there was a wave of aerial photography, and we thought that we might be able to do it underwater."

In this way, from the "dry duck" who couldn’t even swim at the beginning, to the diving expert who could control the machine in the water and move around, Sun Xun and the team developed a set of underwater photography methodology almost from scratch.

There were many differences between underwater photography and shooting on the ground. In particular, shooting in the field was greatly affected by the weather and water conditions, and it was difficult to communicate underwater and underwater. There were three core members of the team, each performing their own duties, and all of them were indispensable: Sun Xun was responsible for the underwater handheld, composition, and camera movement; the second person was responsible for monitoring the focus on the ground and communicating with the ground photography team; there was another person responsible for equipment, coordinating actors, adjusting underwater props, costumes, etc.

　At the same time, the photographer also has to have multiple roles while holding the camera, not only to control the buoyancy, but also to control the machine, to ensure the focus and composition during the movement, and to always pay attention to the safety of the actors. Many directors are not familiar with underwater shooting, and the pre-designed split shots are difficult to complete in actual shooting. For example, due to the influence of buoyancy, the actors will naturally float up when they fall into the water. In order to achieve the "sinking" effect pursued by the director, the team had to bury the Weiya point underwater, "so that they can pull it in reverse, so that they can control the people to slowly go down."

In addition, the actor’s water and physical fitness will also affect the shooting effect. The photographer needs to make an agreement with the actor in advance for underwater gestures such as "rise, sink, take another shot", and pay close attention to the actor’s state. At the scene, the host Roman also changed into equipment and challenged a "drowning scene" shooting. After just shooting for a while, not only did his nose get into water, but his physical strength was also exhausted, and he experienced the difficulty of shooting underwater.

Sun Xun admits that this kind of "hard work" is the norm in this type of work. Because the crew often focuses on shooting underwater scenes a few days ago or when they are close to finishing, the time is tight and the task is heavy. "Generally, it takes 14 to 16 hours to shoot every day, and sometimes even 20 hours."

"If you really come to the scene to watch our filming, you will definitely feel very bitter, but as people who love this profession, we are very excited to shoot, we don’t feel hard, and we don’t feel cold. My favorite is coming out of the water. The director said: Great, this is what I want, I feel very fulfilled!"

In the process of learning, Sun Xun often revisits the classic Hollywood films. As early as the 1954 film "Black Lake Demon Pond", the pioneers began to experiment with underwater photography, and he was deeply admired for his spirit of exploration.

In contrast, Sun Xun said bluntly that the domestic team has a lot of room for improvement in both technology and equipment, but he firmly believes that with the continuous improvement of the industrialization level of domestic films and the improvement of the process, the trickle will definitely merge into rivers and seas, and the underwater lens will definitely record more exciting Chinese stories.

In the past two days, the news of Evergrande boss Xu Jiayin returning to his hometown has easily occupied the headlines of major media. Xu Jiayin is from Taikang, Henan. Over the years, he has invested more than one billion yuan to build schools, hospitals, and industrial bases, and Xu Jiayin has been "walking" with his hometown frequently. And this time, Xu Jiayin and his wife Ding Yumei accompanied his father back to his hometown. What did he do? The editor will decipher it for you as soon as possible, and the details you want to see are here.

What kind of hometown flavor did you eat back home?

Sweet potato, sweet potato soup, black wotou, boiled cabbage and radish… Returning to the old house in Jutaigang Village, Xu Jiayin, his wife, and the villagers sat around the old house and ate a sweet meal to reminisce about the hard life in the past. On the table was Xu Jiayin’s childhood home-cooked dishes.

In October 1958, Xu Jiayin was born into a poor peasant family in Jutaigang Village. The next year, due to illness, no money and no place to treat, Xu Jiayin became "half an orphan" and grew up under the care of his elderly grandmother. Looking at the mottled walls, potholed floors, worn bed boards and bamboo back baskets of the old house, Xu Jiayin opened the chatterbox: "We grew up eating sweet potatoes and sweet potato noodles. We laid, covered and wore patches and patches. Now everyone’s life is better, and the food, clothing and housing are getting better and better."

Who is the old father?

Xu Jiayin returned to his hometown this time to accompany his 96-year-old father, Xu Xiangao. The Xu family lived in the village of Gaotaigang, which was the revolutionary base of the Ji-Lu-Yu Military Region during the Anti-Japanese War. Xu Xiangao joined the revolution in 1938 when he was only 16 years old. He joined the army that year and joined the party that year. After the war ended, Xu Xiangao was demobilized in 1946 due to injury and returned to his hometown to work in agriculture.

Xu’s father is an old revolutionary party member, and Xu Jiayin, who is "rooted in Miao Hong", also loves the party and is patriotic. As early as August 2002, Xu Jiayin led Evergrande to establish the first private enterprise party committee in Guangzhou and served as the party secretary. Evergrande currently has 140,000 employees and more than 10,000 party members.

What did the boss do when he returned to his hometown this time?

In addition to visiting his hometown parents, Xu Jiayin made a special trip to visit four schools, a hospital and an agricultural base built with a donation of more than 1 billion yuan.

In 1998, Xu Jiayin just started his business, donated 1 million yuan to establish a primary school in his hometown, and donated 5.80 million to build roads and install tap water and drainage systems in the village. Beginning in 2016, Xu Jiayin donated another 1 billion yuan to build Jiayin Middle School, Jiayin High School, Gaoxian Hospital and Modern Ecological Circular Agriculture Base, etc., and also established a 100 million yuan education for poverty alleviation fund.

This time, Xu Jiayin decided to donate 650 million return to his hometown, among which 300 million the construction of Jiayin Middle School and High School, and plans to put it into use before the start of school on September 1, 2019; 250 million yuan to complete the expansion of Jiayin High School; Donated 100 million yuan to purchase medical equipment for Gaoxian Branch of Taikang County People’s Hospital.
During his return to his hometown, Xu Jiayin also made a special trip to his home to see the couple of high school physics teacher Cheng Shoude and high school mathematics teacher Zhou Yuan, thanking the teacher for his tireless education.

Is she the first wife of 35 years of marriage?

When Xu Jiayin returned to his hometown this time, he brought his hair-bearing wife Ding Yumei to visit the parents and villagers, distributed candy to the children of Jutaigang Village, and took photos with the parents and villagers in the yard. Ding Yumei, who was born in an ordinary worker’s family, said with emotion, "When I went home with Jiayin 35 years ago to get married, the poor in the village was so poor that I couldn’t say it. Now it has changed a lot."

It is understood that Ding Yumei and Xu Jiayin have been close to each other and have been silently supporting her husband’s career. This time, she and Xu Jiayin returned to their hometowns to visit their parents and take photos with everyone. It was her first public appearance.
