Closing a school refers to the act of blocking the school when the number of students in the school campus is below a certain standard. Generally speaking, closed schools are university campuses, especially during holidays. When there are too few students in the school, the remaining students are often unified in a dormitory, registered and issued access permits to restrict foreigners from entering the school at will.
According to the epidemic situation in the province where colleges and universities are located, if there is an epidemic situation in this province, the suspension time will be longer, otherwise it will be shorter. Because the main students come from all over the country, once the school starts, traffic in all directions should prevent and control the epidemic. There is no way to guarantee the safety of college students on their way back to school. After returning to school, students need to stay in the dormitory together, so there is no small risk of COVID-19 infection. In order to prevent and control the epidemic and strengthen management, colleges and universities implement closed management to prevent students from going out to be infected with the epidemic and strengthen the protection of college students.
