Do I need isolation when I work in Beichen District, Tianjin and return to Xinzheng, Zhengzhou?

If your pass code and health code are green and your body temperature is normal, you don't need isolation. If the health code is green and the passing code is red, nucleic acid testing is needed. If it is negative, it can be isolated in the community home. If the health codes are all red, you must go to the designated hospital for isolation testing. The condition of 2 1 day must be met, and all four tests are qualified. Enter social groups. Supervise life. Until it turns completely green. If you are not sure and necessary, you'd better not move. Consciously for yourself, for your family, for your friends and for the society, this is the obligation of every citizen.
