At the end of August, some universities ushered in the back-to-school season. Although I have said that the epidemic has been effectively controlled, there are still some cases of rebound in some areas, which is a severe test for colleges and universities to return to school. How to return to school, when to return to school, and the preventive measures to be taken after returning to school are all factors that schools should consider. So, what is the difference between the new semester under the epidemic and peacetime? 1. No gathering activities. Different from primary schools, junior high schools and senior high schools, universities have more party activities. But how to solve this contradiction seems to be an important factor for schools to consider at present. Because the university is a relatively open small society, many related activities will be held during the school period, which plays an important role in the healthy development of students. Therefore, it is very important for college students to hold these activities. However, it is worth noting that although the epidemic situation in China has been controlled, it is easy to spread the virus after the opening of colleges and universities, which is extremely unfavorable for the prevention and control of the epidemic situation in China. Therefore, colleges and universities should introduce relevant policies to weigh these contradictions.

Wearing masks and protective masks is the most important thing to prevent the spread of the virus at the moment of the epidemic. It is necessary to wear a mask during the opening of colleges and universities, so as to prevent the spread of the virus. Especially in some public places, there should be staff wearing masks, which plays an important role in the life and health of college students and teachers.

It is necessary to take a temperature measurement. Temperature measurement is a tool to detect COVID-19. Although it can't measure whether you have COVID-19 100%, it plays an important role in the prevention and control of COVID-19. Therefore, after the school starts, the school should actively take temperature measurement and report it truthfully, which is also very important for students' health.

Because of the epidemic situation, major universities have long implemented offline teaching. For students who are not in school, there are many things that cannot be solved. Therefore, it is very necessary for colleges and universities to start school in autumn, but protective measures should be taken.
