At present, defending NCP is very important in the world. Now that we start school, we should pay more attention to it. We can do something to prevent and control NCP. Go to bed early, get up early and exercise regularly. Wear a mask when you go out and wash your hands frequently when you go home. Do not eat wild animals, you can eat some chicken, duck and beef. Don't go out on weekends. Don't go to crowded places. Good luck to us<br>
