Where do Tianshui people go abroad for physical examination?

When you say physical examination, you mean general physical examination, and you can go to major regular hospitals. If you are talking about the health certificate of going abroad, you need to go to the local entry-exit inspection and quarantine bureau or the international travel health care center designated by the quarantine bureau to apply for the international travel health check certificate (commonly known as Xiaohongshu) and the international vaccination or preventive measures certificate (commonly known as Little Yellow Book).
