Will the health code change color after two hours' journey?

The 2-hour trip code of the route will not be recorded.

If you stay in a city for more than 4 hours, you will be judged as staying. If it takes less than 4 hours, such as passing through a city by train and not getting off or leaving the station, the health code will not change color.

At present, the stop time of high-speed trains is short, generally only stopping at one station for 1-2 minutes; The stop time of the ordinary train is a little longer, and the stopover time is about 5-20 minutes. So if you take the train through the middle and high risk area, your health code will not change.
