Yes Cross-border registration of Chinese and Western medicine is not very popular in the whole country, but this topic has always attracted much attention and caused a lot of discussion. Cross-border registration of Chinese and western medicine refers to some doctors who have knowledge of Chinese and western medicine and have obtained dual qualifications through corresponding examinations. The purpose of this cross-border registration is to better integrate Chinese and Western medicine resources and provide more comprehensive medical services. However, in order to achieve the popularization of cross-border registration of Chinese and Western medicine in China, we still need to overcome some challenges and problems. First of all, there are some differences in the subject system and treatment theory of Chinese and Western medicine, and relevant education and training are needed to bridge these differences. Secondly, the laws, regulations and management systems of Chinese and western medicines need to be adjusted and improved accordingly to adapt to the implementation of cross-border registration of Chinese and western medicines. In addition, it is necessary to establish a corresponding assessment and certification mechanism to ensure the professional level and safety of cross-border registered doctors. Although the cross-border registration of Chinese and Western medicine is not popular in the whole country, some places have begun to try to implement this system, such as setting up integrated Chinese and Western medicine departments in some universities and general hospitals of traditional Chinese medicine to train doctors with knowledge of Chinese and Western medicine. With the development and promotion of integrated traditional Chinese and western medicine, cross-border registration of traditional Chinese and western medicine is expected to be more widely recognized and applied in the future.
