Qingcheng police code and health code have different colors.

It's different. Qingcheng code is a combination of formation code, health code and warning code. In principle, every time we go to a place, we use the Qingcheng code to scan the Qingcheng code of that place, and then the Qingcheng code will show the place you passed. If the code colors are inconsistent, the query result of Qingcheng Medical Code shall prevail.
