To apply for a health certificate, you must go to the local disease prevention and control center or the medical and health institution that undertakes preventive health examination after approval by the health administrative department. If this work is carried out without approval, the health supervision institution will not accept the issuance of health certificates.
The main diseases involved in health examination are dysentery, typhoid fever, active tuberculosis, dermatosis (infectious) and other infectious diseases. If you find these diseases, don't engage in hairdressing and beauty, direct contact with imported food, public toilets and other work that directly serves customers. You can only work if you are cured.
