They are divided into three colors: red team, yellow code and green code. The visit of the green representative shows that the applicant has nothing to do with COVID-19's case; Red indicates that entry is prohibited, indicating that the applicant is a relevant person in COVID-19, including confirmed cases, suspected cases or close contacts; Yellow represents the person who has reported fever, acute cough and other symptoms or general contacts. It is suggested to adopt self-health management, including daily temperature measurement and personal hygiene.
