Red team becomes a green code, will it become a yellow code?

Yes According to relevant public information, the health code will turn red after people are positive and green after people are negative. The color of the health code depends on the epidemic risk in the passing area, and the health code will continue to turn yellow after reaching the middle and high risk area. The health code is based on the actual real data, which can be generated by citizens or people who have returned to work on their own online declaration and background audit.
