In the low-risk areas of the province, only the health code and the bus code are checked, and the yellow code is not checked. The bus code without stars can get off the highway normally. People in low-risk areas outside the province need to hold a 48-hour nucleic acid test certificate to enter Zheng, and check the health code and travel code.
If it is a yellow code or a trip code with an asterisk, you need to provide proof that the nucleic acid is negative within 48 hours, and you need to register for temperature measurement to get off the high speed normally. People from outside the province will be given a yellow code after entering Zheng. Those who are given the yellow code need to complete three days. After both tests are negative, you can automatically transcode or apply for a green code from the community.
