The health bureau is only a management unit, not a medical unit. It cannot apply for a health certificate. To apply for a health certificate, you need to go to a hospital designated by the Health Bureau to be effective. The Health Bureau has strict management requirements for health certificates. In order to prevent false information, you need to register with your real name with your ID card, and you can get a health certificate only after passing the medical examination. Units that use undocumented and invalid health certificates will be punished.
