If there are stars in the green code, the attitudes of different places may be different. In some places, the stars with green code should be isolated, and in some places, the stars with green code will return to the original road. Therefore, before going home, you still need to know the local policies and travel according to the actual situation.
The asterisk marks will change according to the identification of high-risk areas in cities by epidemic prevention departments, and the data will be updated according to the latest information released by local health and wellness committees. There will be a certain time difference in data update, and synchronization is generally completed within 24 hours.
Preventive measures for tripping codes
1. If you don't stop to pass through a closed-loop medium-risk area, the health code generally won't change color, but you can see from the trip code that you have passed this area, and travel in some areas will be restricted.
2, there are special circumstances, so it is best to bypass the high-risk areas, or try not to stay in the service area.
3. If you get off the expressway, the urban roads in the middle and high risk areas may change color, so be careful.
4. For the range of medium and high risk areas, you can check the latest situation at any time on the health code page.
