Is it okay to return to Zheng on the 7 th and report the itinerary on the 5 th?

Of course. It is necessary to report to Zheng 48 hours in advance when returning to Zheng, and implement the prevention and control of the "landing inspection" epidemic situation. Don't relax health tips during the National Day holiday. According to the epidemic information released by National Health Commission, the domestic epidemic situation is repeated, and there are still COVID-19 epidemics in many provinces, and some provinces have inter-provincial cases. So just report 48 hours in advance.
