There is no way to change the time and date of getting a good health certificate. The health certificate is to go to the hospital according to the process, mainly to check whether there is tuberculosis. In addition, stool culture should be carried out to see whether there are typhoid bacilli and paratyphoid bacilli, to determine whether there are intestinal infectious diseases, and to draw blood to test whether there are hepatitis B virus carriers. The test report can't be changed if the health certificate is painted into a card by a health hospital with computer photo technology. Only you want to wait until that day.
