According to the level of the epidemic in each region, the provinces are divided into three risk levels: low risk, medium risk and high risk, using the county as the unit.
Low-risk areas are not the same as no risk, and it is usually important to do a good job of personal protection. Maintaining good hygiene habits, such as wearing a mask, washing hands regularly, paying attention to cough etiquette, ventilating and cleaning daily, reducing visits to crowded places, keeping a certain distance from colleagues after resuming work and production, and spreading out meals will effectively reduce the risk of infection. If you go alone to open places with low population density such as parks and mountains, you can temporarily not wear a mask, if the population density is high to wear a mask throughout.
