When using the cafeteria for meals during a new crown pneumonia outbreak, the following issues should be noted: 1. When eating, always remove your mask at the last minute; 2. After removing your mask, communicate and talk as little as possible during meals. If communication is needed, the communication object is not going out and has no recent travel history in an epidemic-prone area, so the risk is relatively low and moderate communication can take place; 3. Meals can be divided into periods and floors to reduce the density of the dining staff; 4. Keep a certain distance from other people during meals and avoid close dining and communal dining.
