The health certificate is valid for one year and will be re-examined every year. A new health certificate cannot be exchanged for a new one. As long as the validity of the health certificate expires, you need to bring relevant information to re-apply, go to the health and epidemic prevention department, and then have a physical examination. Physical examination in general health and epidemic prevention stations is acceptable, with 2 photos of 1 inch. If there is no infectious disease, you can get a health certificate within 7 working days.
