What should I do if the health code information is incorrectly filled in and becomes a yellow code?

I checked for you. If the health code turns yellow for no reason, then we can open the health code, find the "self-complaint" in the upper left corner, click on the complaint, or check it after reinstallation.

If it is a yellow code caused by entering an epidemic area or contacting with a suspected case, it needs to be isolated according to the regulations, the source and daily health status should be declared in a small program, and the relevant staff should be registered, so that the yellow code will automatically become a green code if there is no abnormality in 14 days.
