Let me talk about a few concepts first. Medical universities or medical schools have affiliated hospitals and practice hospitals. Affiliated hospitals are divided into directly affiliated hospitals and non-directly affiliated hospitals. Medical college students have to leave the school headquarters to study clinical courses, including theoretical courses and internships, in affiliated hospitals since their senior year. In the fifth year, they went to the affiliated hospital and the internship hospital for internship, which was basically the same as being a doctor. Affiliated hospitals directly under the central government are also responsible for the training of Clinical Fellow and doctoral students in their medical universities or medical schools. Administratively, the affiliated hospital directly under the hospital belongs to the school. At the same time, hospital doctors should not only enter the title of attending physician and chief physician, but also enter the title of lecturer and professor, because they also belong to half of the school teachers. Non-directly affiliated hospitals and practicing hospitals are not affiliated to medical schools or medical universities administratively, but only have cooperative relations. The school grants funds to hospitals, which are responsible for training students for internships. Nowadays, many hospitals hope to become teaching hospitals or affiliated hospitals of medical colleges, because this can improve their level and reputation.
