Can Tianjin Health Certificate be used across regions?

Can be cross-regional.

Health certificates can generally be used across cities, but also in the same province across cities. Handling a health certificate is only beneficial to the parties concerned. For a considerable number of staff, it is both costly and troublesome, and there is also the risk of unemployment.

The content of health certificate mainly involves the inspection of infectious diseases to ensure the health and safety of service industry. Personnel engaged in toxic, harmful and radioactive operations do not belong to the service industry and do not need to hold health certificates at all, so it cannot be said that health certificates are an effective way to understand physical condition and ensure health and safety.
