What is the rule of health code discoloration?

Health code color change rules: residents in fixed risk areas, residents in high risk areas are red, residents in medium risk areas are yellow, and residents in low risk areas are green. Low-risk residents go to high-risk and medium-risk areas, and those with green codes enter high-risk and medium-risk areas. When they stay for an hour and their phones are turned on, their health codes will automatically turn red and yellow. Medium-risk residents go to low-risk areas: from the arrival time, the first 2 1 day is yellow code, and the normal results of nucleic acid detection are uploaded after 2 1 day, which turns green. What is not uploaded is always yellow code. High-risk residents go to low-risk areas: from the arrival time, the first 14 days is the red team, the last 7 days is the yellow code, and the normal results of nucleic acid detection are uploaded 2 1 day later, which turns green. What is not uploaded is always yellow code.

1. In order to promote the mutual recognition of local "health codes", the national comprehensive government service platform provides three ways to realize cross-provincial mutual recognition and sharing. The first way is to add a cross-regional mutual recognition function to the local "health code" without changing the existing local "health code". Second, the local "health code" is connected with the national comprehensive government service platform "epidemic prevention information code", and the national comprehensive government service platform "epidemic prevention information code" is used as an intermediary to realize cross-regional mutual recognition of "health code". The third is the area where the local "health code" has not yet been built. The national integrated government service platform "epidemic prevention information code" can be directly adopted, and at the same time, the information related to epidemic prevention and health in various places can be combined to realize cross-regional mutual recognition.
