The so-called formal hospital mainly refers to one that obtains a business license through normal channels and meets the equipment installation requirements of different levels of hospitals, such as medical equipment, environment, medical and health personnel, etc. At the same time, the doctors and nurses who are treating patients are all personnel who have obtained nationally certified qualification certificates, and they must have certificates to treat patients. Practicing medicine without a license is illegal. This happens in some illegal clinics or small clinics, so you need to pay attention to it.
