People who hold the green code enter the low-risk area without special circumstances, and the health code does not change color, that is, it displays normal green; If the green code holder stays for one hour after entering the high or medium risk area, the mobile phone can receive roaming information normally, and the health code will automatically change color from the original green code to the yellow code or the red code.
When a person with a yellow code or red team enters a low-risk area, he can record the time of arrival in the low-risk area by himself as long as he turns on his mobile phone. After quarantine 14 days, and the person holding the health code has not become a close contact or case, the health code will be automatically changed to a normal green code.
If the code holder becomes a close contact or case, and the information is reported to the coding company platform by the code holder himself, then the coding platform will turn the code holder's green health code into red.
