What should be paid attention to in community security under the COVID-19 epidemic?

Strict registration system. Security refers to maintaining public order, which is a professional job. Its main responsibility is to be responsible for fire prevention, theft prevention and personal safety in the area. Community security should do a good job in isolating the epidemic into the community, so we should pay attention to the strict registration system for outsiders. People in high-risk areas must produce negative nucleic acid certificates within 48 hours before entering the community, which is a very important post.
