However, with the development of the times, the traditional education model is no longer completely applicable, and the cultivation of talents specialized in integrative Chinese and Western medicine is facing some new problems. Based on the requirement of “keeping integrity and innovation” clearly put forward by General Secretary Xi Jinping since the 18th National Congress of the Communist Party of China, this paper systematically thinks about the construction of integrated traditional Chinese and Western medicine and its personnel training in colleges and universities under the guidance of this ideology. The ideas and paths of talent training are put forward in terms of platform construction, characteristic construction, curriculum design, and teacher team construction.展开更多
