Can I change the code if I have one defense and two retreats?

Yes Sub-close contact personnel, home isolation personnel, home health monitoring personnel, key personnel involved in the field of prevention and control who have not been tested for nucleic acid (including key personnel who have purchased one-off and two-antibody drugs), and health code yellow code personnel from other provinces, the health code is judged as yellow code. The key personnel who buy one-refund and two-antibody drugs will be judged as yellow code personnel by the system, and the green code will be changed into yellow code.
