As a traditional martial art in China, Tai Chi Chuan has excellent health benefits along with its combat function.Studies have shown that Tai Chi as an exercise prescription can significantly reduce the incidence of cancer, but the complexity of Tai Chi Chuan routines, poor disease targeting, and the lack of traditional internal mental and physical training method limit the healing of tumours and other diseases. For this reason, we have established the Medical Tai Chi Exercise Healing System（MTCEH）, which integrates Tai Chi exercise, traditional Chinese internal mental and physical training method, rehabilitation medicine and sports medicine methods, on the basis of evidence-based medicine and with the aim of targeting different tumour treatments. With the characteristics of easily learning, internal and external training, and individualised treatment of tumours, this series of routines effectively combines traditional oriental Tai Chi martial arts with tumour treatment, which opens up a beautiful and mysterious oriental healing journey for integrative medicine.
