If you are fired, I suggest you go to a regular five-star hotel, preferably state-owned. In a regular hospital, as far as our hotel is concerned, you will be required to have a physical examination and get a health certificate before joining the job, but if you are the front desk, the hospital will let you choose whether to check hepatitis B, and you can choose not to check it. It's no problem to do so. It will not affect your application for a health certificate.
The state has written words to ensure the normal employment of hepatitis B virus carriers.
Regarding the employment of HBV carriers, generally speaking, except for a few industries and professional posts with special requirements, there should be no discrimination in recruiting HBV carriers.
Good luck.
