Take the university as an example. The students in each university come from all corners of the country. After receiving the notice of returning to school, students will choose a series of means of transportation such as trains, bullet trains and planes to report to the school. No one knows whether they will meet a small patient on the road.
If a student is unfortunately infected midway, it is easy to spread widely after arriving at school.
Therefore, colleges and universities should start school under the condition that the epidemic situation is completely controlled. College students do not return to school early, which is not only to abide by the regulations of the school, but also to be responsible for themselves and others. Reasonable planning, study at home, do a good job of protection, and so on. ?
