As long as they are not from high-risk areas and in good health, there is no need for isolation, depending on the local policy requirements of the destination. In general, many cities in China don't need to be called to isolate people from zero-epidemic cities in low-risk areas, but they should need the green code of travel code or negative proof of nucleic acid test. If there are a few high-risk areas in the departure city, but the low-risk areas account for the vast majority of the strict areas, people from this city should be required to conduct home isolation or health monitoring. If the epidemic situation in the starting city is serious, then the destination city may isolate people from the city. The specific isolation requirements depend on the local policy of the destination.
