How long is it appropriate for Heilongjiang Province to urgently apply for overseas health certificates?

The time is 2 days, such as Monday, Wednesday, etc. It's best to go to the nearest health and epidemic prevention station. For example, the health and epidemic prevention station in Dongcheng District is located in Beijunmu Temple Hutong. Remember that the processing time is from Monday to Friday morning, so you should go early and come back early, and if you go late, you will have to queue for a long time.
