1. National laws and regulations require employees to hold health certificates. So please get a health certificate in time after the physical examination. The CDC only keeps the certificate for two months, and then it won't be issued.
2. Please check the valid information such as name, type of work, age and gender. When receiving the health certificate, point out the mistakes in time so as to correct them on the spot.
3. If the physical examination is positive and you can't get a health certificate, you can ask to check the physical examination report and review it for free to prevent the medical examination report from being wrong.
