Will the health code change color when changing trains in Changsha?

No, because as of 202 1, 1 1, Changsha is not a high-risk area. As long as you stay in the high-risk area for more than two hours, your health code will change color.

The most important part of health code is mobile phone location based on mobile phone number, consumption record, travel and plane record based on ID number, filling in travel information or scanning scene location registration, etc. , and combined with the epidemic situation, big data analysis shows the results.

The QR code of the electronic health card has three colors, and different colors represent different grades:

The first one is green and can travel normally. But in the past 14 days, those who have stayed in high and medium risk areas or epidemic areas should receive nucleic acid testing for 7 consecutive days or provide qualified test results;

The second is yellow, which restricts travel and accepts nucleic acid testing. You can travel with a negative certificate of nucleic acid test for nearly 7 days, but you are not allowed to enter and leave schools, factories, large shopping malls, large farmers' markets and other crowded places and relatively closed places;

The third type is red, and it is forbidden to travel. It is necessary to contact the local community (village group) or county (city) district CDC as soon as possible and accept centralized isolation medical observation.
