Standardized training refers to the standardized training of residents. Through clinical practice, we can cultivate senior talents with high theoretical professional knowledge and operational professional skills, transport outstanding talents for lower-level hospitals, and relieve the employment pressure of medical students. In 2009, the Central Committee of the Communist Party of China and the State Council issued "Opinions on Deepening the Reform of Medical and Health System", clearly proposing "establishing a standardized training system for residents". Conditional areas such as Tianjin, Shanghai, Liaoning, Jiangsu, Beijing and Zhejiang will be tested first according to the national deployment, and will be tested in 20 10, 201,201and 20/kloc-0 respectively in 2009. It is also explicitly required that all clinicians with bachelor degree or above who enter medical posts should receive standardized training for residents. 20 13- 12, the former national health and family planning commission and other seven departments issued the "Guiding Opinions on Establishing a Standardized Training System for Residents" (hereinafter referred to as "Guiding Opinions"), which marked that China began to promote the establishment of a standardized training system for residents at the national level. However, considering the uneven economic and social development in the country and the great differences in the basis of standardized training for residents, the Guiding Opinions did not implement a one-size-fits-all approach, but stipulated: "In 20 15 years, all provinces (autonomous regions and municipalities) will start standardized training for residents in an all-round way; By 2020, a standardized training system for residents will be basically established, and all clinicians with bachelor's degree or above who have newly entered medical posts will receive standardized training for residents, allowing all localities to take 2020 as a transitional period for establishing a standardized training system for residents.
