Shaw Hai, captain of China's peacekeeping medical detachment to Liberia and deputy director of a hospital in the Nanjing Military Region, told reporters, "According to the memorandum of understanding signed with the United Nations, we are responsible for the medical care of United Nations staff and peacekeepers as well as local emergency patients licensed by the United Nations, but delivering medical care to the local people is our tradition. " "We also have an important mission, which is to let the ordinary people of Liberia know China and understand China." Hania, a 95-year-old woman, has been bedridden for more than five years. After carefully examining her, orthopedic surgeon Wu Chengru said with a long sigh, "There is no problem with the bones, there should be a problem with the part of the brain responsible for motor coordination, and there is nothing we can do about this disease, which belongs to the category of brain surgery." According to the agreement with the United Nations, the Chinese medical team is configured according to the standard of the second-level hospital, not responsible for the treatment of brain surgery. Dr. Wu Chengru said, "It's very helpless and complicated in my heart. This disease, if it were in China, although we may not be able to cure this 95-year-old because of her age, we can at least help her solve a lot of problems." Meanwhile, in one of the largest houses in the village, Li Jin, an internal medicine infectious disease doctor, has unfolded a piece of white screen and introduced knowledge about malaria to dozens of villagers with a slide projector. Johnson, a villager, told the reporter, "You know, people die of malaria in our village every year, mostly children." Wang Lin then also went up to the humble podium and began to introduce knowledge about AIDS and prevention, and the audience became even more attentive - the infection rate of AIDS in Liberia is as high as 30%. "Suddenly, suddenly, suddenly," the tranquility of the village was shattered. It turned out that the epidemic prevention doctor Tan Weilong had turned on his smoke sprayer and was spraying white smoke into the bushes around the village houses. This smoke effectively kills mosquitoes, tsetse flies, cockroaches, and other pests, and serves to prevent malaria, dengue fever, scrub typhus, and sleeping sickness, which is very necessary in the area. "Wonderful!" After learning about the situation, the villagers gave a thumbs up. With an uncontrollable smile on his face, the village headman, Kadi, shouted from the village clearing, "Please be quiet! We would like to thank the doctors from China, you have brought us health. We are determined to fix the road from Zwedru to our village so that you can come more often, any time you want. Now, come and dance with us to celebrate this memorable occasion! As the drums beat, an old woman began to wiggle and jump rhythmically, while the village chief danced on top of a large basket of bread presented by the medical team, and a large group of children cheered after him. The villager, Tere, said excitedly, "In Liberia, we call doctors angels, and these Chinese doctors are our angels".
