Novel coronavirus pneumonia lights up the campus of the new day with a long night of street closure. The volunteers who have just finished their day's work and have not yet taken off their protective clothing 00 have returned to the dormitory. The "wind fire wheel" he pedals is a pulley trolley used to transport materials during the day. "This posture is just one word 'handsome'," little brother with love in his heart, hard work "... This relaxed and interesting video has been spread on the Internet recently. In the closed campus of Xi'an University, college student volunteers have undertaken heavy work and can enjoy themselves. This optimism is moving. The "Fengchi" in the video is Li Yuanxiang, an epidemic prevention and control volunteer of Chang'an University. Because of the epidemic, Chang'an University implemented the control policy of closing the building, and volunteers sent boxed lunch to the door of each dormitory every day. Every morning, noon and evening, Li Yuanxiang is responsible for delivering meals to the students closed in the dormitory. On the evening of December 21, 2021, Li Yuanxiang, who was pushing his car back to the dormitory, had a whim: "why not slide back? It's fast and energy-saving." Li shuaijia, a fellow volunteer, photographed the scene. Li Yuanxiang said that on New Year's day, the school specially added meals to each student and gave an extra fried vegetable and drink. He and his roommate watched the new year's party in the dormitory, watched videos with his family and welcomed the new year together. Hu Han, a student of Xi'an Jiaotong University who lives in Anhui Province, is looking forward to going home as soon as possible, but he is also prepared that he can't go home for the new year. As a party member and student union cadre, Hu Han signed up to join the volunteer team immediately after the outbreak. In just a few days, more than 1000 volunteers have been reserved in the three volunteer groups established in the Yanta campus of Xi'an Jiaotong University, which moved Hu Han. There are many warm little things that Hu Han remembers deeply. Once, the volunteer group temporarily notified that there was an urgent task and needed to assemble at 6:45 the next day. The notice came very late, but no one was absent the next day. The sudden epidemic has disrupted the peaceful life of college students. All departments of Xi'an Jiaotong University quickly collect students' demands, summarize them every day and try their best to implement them. "There are enough materials in the school. Although the dishes in the canteen are not as rich as before, they can meet the needs of three meals a day." On New Year's day, some colleges also prepared "snack blind boxes" for students, including melon seeds, apples, snacks, etc. In order to reduce the waiting time for nucleic acid detection, the student team of Xi'an Jiaotong University independently developed the "Xijiao helper" applet. Click the applet to see the distribution and estimated waiting time of each detection point in the school. After the first "youth volunteer commando for epidemic prevention and control" recruitment information of Xi'an Foreign Studies University was sent out, 500 volunteers signed up within one hour. Since then, the team has grown rapidly, and there are nearly 3000 people at present. "Please wear a mask and keep a distance of one meter", "the team lined up here, don't worry"... On December 25, 2021, Zhang Hailong, dressed in a volunteer red vest, stayed at the nucleic acid detection point of the school for 5 hours. As the Secretary of the Youth League general branch of the school youth volunteer corps, he and his volunteer partners were busy until 2:40 the next day. The responsible attitude of the volunteers made Zhang Hailong, who returned to the dormitory, unable to calm down for a long time. He wrote this sentence: "when the epidemic comes, you stand up and go in the opposite direction... The volunteer red you wear is the most amazing color in the front line of the fight against the epidemic." In Xi'an at the end of December 2021, the temperature at night is below zero. In order to help volunteers resist the cold, the students sent warm stickers one after another. There is a note in some warm stickers: "to the most lovely person: may all regrets this winter be the foreshadowing of spring surprises." "This is a two-way warm process. Volunteers try their best to protect their teachers and classmates, and students also try their best to bring warm protection to volunteers." Zhang Hailong said. In the epidemic situation examination, the volunteers of Xi'an Foreign Studies University fully participated in the voluntary services in the fields of assisting nucleic acid detection, catering distribution, environmental killing and "flow regulation" information collection. Among them, an environmental killing team composed of 25 retired college students is particularly eye-catching. "All public areas in the student dormitory building of the whole school are within our scope of responsibility." Ren Le, leader of the environmental killing group, told the China Youth Daily · China youth network that there was no elevator in the dormitory building. Volunteers had to carry more than 20 kg killing pots to each floor to kill. They climbed down several floors and their clothes were often wet. After the killing work, the team members had pain in their shoulders and backs. In order not to affect the work of the next day, several volunteers "recruit" each other in the work group - "put paper towels on the places where the shoulders are stressed, as we used to do during the practice", "try to tighten the shoulder straps and make the medicine bucket close to the back, so that the stress can be more uniform". As of December 31, 2021, the school's anti epidemic volunteer service has accumulated more than 10000 person times, and the service time has exceeded 30000 hours. (outlook new era)
