Can health certificate be replaced by physical examination?

If you can't find someone to replace you, you must go in person, because you need a physical examination, but you can entrust someone else to get a health certificate. I must bring my ID card and photos to the CDC and other relevant departments or health institutions approved by the Ministry of Health to undertake preventive health examination. It means that my health certificate is invalid. Workers who are engaged in occupational hazards or have special requirements for health shall undergo occupational health examination.
