What does the health certificate review mean?

Re-examination of health certificate means that if the physical examination data deviates from the normal index or is abnormal after handling the health certificate, it needs to be checked again to determine whether it meets the requirements of handling the health certificate. Only when the recheck data accurately reaches the normal index can the requirements of handling health certificates be met. Health certificate audit may also be to update the health certificate, because the health certificate is valid for one year, and it needs to be reapplied after it expires.
