The theory of “prevention of disease” in traditional Chinese medicine is of great significance in both clinical and preventive traditional Chinese medicine. In recent years，the theory of “prevention of disease” in traditional Chinese medicine has been widely recognized and practiced. The survey conducted in Beijing shows that most people understand the main content of “preventive treatment” as providing consultation，followed by free physical examination and free distribution of conditioning products. From the perspective of the most frequently visited units in the community population，community health service centers account for 39.0% and community health service stations account for 10.7%，and the primary reason for choosing visiting units is to facilitate medical treatment. It is suggested that all parties should strengthen the publicity of the concept of “prevention of disease” of traditional Chinese medicine and innovate the service mode of “prevention of disease” of traditional Chinese medicine. The government also needs to further strengthen its support for “prevention of disease” of traditional Chinese medicine.
