Anhui traditional Chinese medicine culture. Bei Huatuo refers to Hua Tuo, a doctor in Bozhou, Anhui Province in the Eastern Han Dynasty, and Nan Xin 'an refers to Xin 'an County, Anhui Province, which was called Xin 'an in ancient times. As Huatuo came from Anhui, Huatuo vigorously promoted the characteristic culture of Anhui traditional Chinese medicine. Therefore, Beihuatuo and Nanxin 'an are collectively referred to as the characteristic culture of Anhui traditional Chinese medicine, which is a strategic concept for the construction and development of Anhui traditional Chinese medicine, with a view to revitalizing the cause of Anhui traditional Chinese medicine, restoring the historical glory of Anhui and re-establishing the status of Anhui as a major and powerful province of traditional Chinese medicine.
