If you don't contact with the outside world, you can effectively reduce an infection phenomenon, especially in school, because students may not choose to wear masks when they are in class or playing. If one student is infected, the whole campus will be in a panic. The school also has relevant regulations. If it is delivered to the campus by express delivery, centralized disinfection should also be carried out. Now the school has been closed all day, and pedestrians and vehicles have to be suspended, so as to better protect the safety of students.
At present, outsiders are not allowed to enter Tsinghua, and students are not allowed to go out. If students go out without permission, they will be punished or expelled directly from school. Because many students were infected because they went out without permission during the epidemic, and the current epidemic situation in Beijing is not optimistic, this practice is also to protect everyone, and they can go out to play at will after the epidemic.
You can't let takeout into the campus because the takeaway brother often contacts many people, so it is easy to cause cross-infection. With the resurgence of the epidemic in Beijing, many universities in Beijing, such as Tsinghua University, have suspended classes. So I hope everyone will pay more attention to protect themselves, cooperate with the school's work and solve the problem fundamentally. If you have any questions, you can contact the relevant school personnel or tell the counselor.
