In fact, I think as far as the current situation is concerned, if it is cross-province, then it is definitely necessary to issue a nucleic acid test report within seven days, so as long as you have a nucleic acid test report within 48 hours, it should be possible.

First, check the prevention and control requirements of the starting point and the end point. In some areas, people entering and leaving the country will be required to have corresponding nucleic acid test certificates, which need to be prepared in advance. Take enough masks to ensure your protective measures during the trip. To apply for the health code of the departure place, some provinces will require to show the green health code before boarding, otherwise it will not be passed. When you arrive at your destination, you need to apply for the local health code when you leave the station. Some cities also require it when taking the subway or bus. Understand that the starting point is to take the APP of urban public transportation (subway, bus), and some cities no longer support cash ticket purchase during the epidemic. Try to remember where you have been and the time at that time in case of emergency.
