Where can I get a health certificate in Taian? how much is it? What items need physical examination? Thank you~

To get these documents, you need to go to the health and epidemic prevention station. If you are talking about Taishan District Epidemic Prevention Station:

It is to the east of Taicheng, to the east of Dongyue Street, and to the right of the third intersection of Daiyin Group to the north (Foguang Road). Take bus No.4 at Chongchong Railway Station, get off at Daiyin and go north.
