Depending on your exposure risk, the health code will be changed to "Yellow Code" or "red team". The "yellow code" indicates the need for home isolation, and the "red team" indicates the need for centralized isolation.
After the health code turns red, our travel will be restricted. If you want to change it back, you can stay in the risk-free area for 14 days and report the formation of the day on time every day. So the red health code can be changed back.
In fact, the "health codes" of Alipay and WeChat are exclusive QR codes generated by comparing the epidemic prevention big data of the communications, transportation, public security and health committees with the health data declared by individuals.
brief introduction
So if the content you declare is different from the comparison of big data, there may be different codes. Indeed, as a health code, it can't know when you are sick. It can only play a monitoring role during the epidemic prevention and control.
The "health code" of WeChat and Alipay is an important identification basis, which provides an important guarantee for our daily travel and orderly flow, and can also effectively reduce the risk of cross-infection.
