Health code is a health code registered by our own phone number, ID card, home address, etc. During the epidemic, we can search for the health code on WeChat or Alipay or other online platforms to register.
Health codes are divided into three colors: green code, yellow code and red code. "Green code" personnel take their temperature at the bayonet or temperature measuring point, and are allowed to pass if there is no fever. "Code Yellow" and "red team" personnel cannot pass. The health code will be transcoded according to personal health status and punching, and the "green code" is valid for three days. During the validity period, citizens must complete health registration at least once before they can get an automatic extension, otherwise they will be turned into "yellow code".
