No, I have to ask for leave. It depends on where you live. If your university and your home are both epidemic areas, or if you have to go home through high-risk places, you must ask for leave, and you will be quarantined when you come back. If the isolation days are not enough, you have to go back. During the period of love, the majority of students should strictly abide by the requirements of epidemic prevention and control, consciously abide by the closed management of the school, strictly control the trajectory of personal daily actions, and must not take time off unless necessary, especially consciously and strictly control the behavior of going out. However, it should be combined with the actual situation of epidemic prevention and control and school work in COVID-19. And report to the school and the place you want to go, such as warm drilling, nucleic acid and so on.
