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.
