One person can apply for two health certificates. There are two kinds of health certificates: one is general health certificate. Then the other is a food health certificate, which is needed by people in the catering industry. So a person can apply for two different types of health certificates. The health certificate is valid for one year, and it will be invalid after one year, so the holder is required to have a physical examination once a year.
