The health code turns yellow because it has passed or stayed in the middle and high risk area. The nucleic acid test report passed, then turned green, and so on.
When the health code turns yellow, it will have a certain impact on travel: it is not allowed to enter and leave some public places and some special places. So how do you make the health code green? We can do two nucleic acid tests in three days, and the interval between the two tests is more than 72 hours and the results are negative. The system will automatically remove the yellow code and turn it into a green code.
