And the health code is divided into three colors, red, yellow and green.

Red code people to implement 14 days of centralized or home quarantine, in the continuous declaration of health punch card 14 days normal will be converted to green code. There are two main reasons, one is because of the epidemic control needs to be assigned a code; the second is because of the individual declaration of the reason was given red and yellow code.

Hangzhou health code implementation of "green code, red code, yellow code" three-color dynamic management: that is, show the green code, the city bright code passes, in and out of Hangzhou sweep code passes;

Show the red code, the implementation of the 14-day centralized or home isolation, in the consecutive declaration of the health punch card after 14 days of normal, it will be converted to a green code; show the yellow code, to carry out 7 days of normal, it will be converted to a green code; show the green code; show the green code. Those displaying a yellow code are subject to centralized or home quarantine for up to 7 days, and will be converted to a green code after declaring health punch cards normal for no more than 7 consecutive days.

So when the health code is red, it is necessary to implement 14 days of centralized or home isolation, and after 14 days of continuous declaration of health punch card normal, it will be converted to green code to pass.
