A general health certificate is enough. Health certificate refers to the health examination conducted by food and drinking water producers, personnel directly engaged in cosmetics production, personnel directly serving customers in public places, hazardous workers, radiation workers and school students before, during and during their employment according to national health laws and regulations.
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.
