This is only a certificate issued after hospital training, which is used in the hospital or the area where it is located. It does not belong to the national labor bureau, or it is a certificate issued by the national professional or personnel bureau.

Standardized training of residents is an important part of medical students' post-graduation education, which is extremely important for cultivating high-level clinicians and improving medical quality. As a link between lifelong medical education (basic education in medical colleges) and continuing medical education (continuing medical education), it occupies an important position and is the key to the formation of medical clinical experts.

For a long time, there has been no standardized resident training system in China. Students graduated from medical colleges and universities and were directly assigned to hospitals for clinical work without training in two disciplines. Their future ability and level depend on the conditions of the hospital, which seriously affects the improvement of the overall quality of the medical team. Since 1980s, many places have resumed the pilot work of resident training. After 10 years of practice, a relatively complete standardized training system and model for residents have been determined and improved.
