Those who display the yellow code should be in the home set or isolated for more than 7 days. For more than 7 consecutive days, you can travel by turning to green code. Health pass codes are divided into three colors: red, yellow and green. According to the regulations, "code red" and "code yellow" personnel cannot pass, and medical treatment or observation should be carried out according to the requirements of the epidemic prevention and control department; "Green code" personnel with normal body temperature can pass, but they need to take protective measures.
Health codes are based on actual data and can be generated by citizens or people who have returned to work through online declaration and background audit. As an individual entering and leaving electronic certificate locally, the QR code can be declared once, which is universal in the whole city. The introduction of the health code aims to make the work of returning to work more accurate, scientific and orderly.
