Xuzhou, Jiangsu Province was affected by the epidemic, and the county suspended offline teaching. The prevention and control of students' own epidemic situation is still very serious, because the population of the school is very large. Once a person is diagnosed, it will affect the whole school and even the whole area, so the infection in the school has to be prevented.

The best way to avoid epidemic infection among students is to isolate at home. Don't go to school, that is, stop offline teaching. Everyone goes home to give lectures through the online live broadcast of the network, and students listen, so as not to contact outsiders, the risk will naturally be reduced, so this method is more mature. After all, it's not just a month or two, it's been a long time. The online teaching mode is relatively mature, and both infrastructure and teachers have adapted to the online live teaching mode.

If students have to stay in school, the risk is very high. For schools, if students want to study at school, the best way is to completely isolate the school. In addition to the necessary daily necessities, they also bought some vegetables, rice, flour, grain and oil. These necessary materials continue to exist, and they are not in contact with outsiders. All the staff and students stayed in the school, but it was very difficult. Because many schools, especially junior high school students, have accommodation, teachers have no accommodation, and there are many school staff, it is impossible not to go home.

However, if the students in the school are isolated in the school and the faculty can go home and do free things normally, then this isolation is meaningless. Students don't contact outsiders, and faculty and staff don't? This case, diagnosed by a faculty member of Zhejiang University, has proved that students may have no problems, but the faculty union has problems. There is a problem with the teaching staff, and the epidemic prevention work of the whole school is still in vain, either all of them are isolated or they go back to their hometown.
