Do a good job in students' family management. For example, if parents often say that they are on business trips, or occasionally go to some areas with high epidemic rates, it is recommended to isolate them after coming back and avoid contact with children.
Third, do a good job in related safety publicity. For example, experts from health and epidemic prevention departments can often be invited to come to the school for guidance, and at the same time, children can be taught how to do self-protection measures every day.
