If you have been to an epidemic area, you need to be strictly isolated and wait for the green code. The confirmed patients turned to yellow code after discharge, and turned to green code normally for 14 days. Suspected patients, close contacts and medical observers turn to the green code after removing observation.
It takes 7 days for the yellow code to change into the green code. The general health code is yellow code, which needs to be collected at home or isolated for 7 days, and it will be turned into green code after 7 days of continuous health declaration. If you have been to an epidemic area, you need to be strictly isolated until it becomes a green code. If you haven't been to an epidemic area, you can give feedback by appealing.
