Pay the price: no way. If you get a job license for the catering industry, you can tell the doctor that you have to issue your own health certificate. He will ask you to pay, that is, the medical examination fee. Then, it is also the same process as the physical examination. You can get a health certificate in a few days. The biggest difference between free and paid is that the state subsidizes the license to engage in the catering industry, which can be handled free of charge. Many people think it is difficult to get a health certificate, that is, they must engage in the catering industry to get a health certificate. Actually, you don't have to. Remember not to eat breakfast before the physical examination. You can drink some water properly, because you may have to have a urine test or something.
