People in Nanjing are also nervous due to the latest COVID-19 outbreak. Students need to obey the following rules to protect themselves.

First, wear masks. Wearing masks is still one of the most effective ways to stop the virus from spreading. Students need to wear masks while in crowded places, such as in the lift, on the bus, in the supermarket and so on. So students should take some masks to school.

Second, wash hands. Wash hands with soap under running water for at least 20 seconds, especially before eating or after using the restroom, touching something dirty, etc.

Third, keep a distance from each other. Try to keep yourselves at a distance from others in and after class. Try not to go to crowded places such as hospitals, railway stations and airports. Keep at least 1 meter away from others all the time.

Fourth, take the temperature often. Each student must take the temperature at least twice a day. If someone has a fever, the teacher should ask the doctor for help at once.
