What should I do in the high-risk area of expressway?

The high-speed rail passes through Nanjing and stays in the middle and high-risk area for no more than two hours, and no isolation measures are taken. Generally speaking, taking the high-speed train through Nanjing is not considered as going to Nanjing as long as it doesn't stop, but it is also possible that the health code will change, such as the yellow code or that it has reached the middle and high risk area in Nanjing. At this time, it is necessary to pay attention, and isolation measures may be taken after arriving at the destination.
