Which hospital in Zoucheng has a health certificate? How long will it take to finish it?

Generally speaking, you don't need to apply for a health certificate in the hospital (unless there are special local regulations), you should go to the local county or municipal centers for disease control and prevention.

As for the time, I don't know. Every place will be a little different. Generally, the time in remote areas is long and the charge is low, up to 7 days. In developed areas, because of advanced methods and equipment, the time is relatively short, and the fees are relatively high. You can get the certificate in 2-3 days at the earliest. But in any case, there must be seven days.
