Hello, personally, I think you are mistaken. Zhang Tianshi, the last generation of Tianshidao, has long since disappeared in War of Resistance against Japanese Aggression, and Shi Tian has never existed in New China. Other reasons for longevity include Taoist teachings, cultivation methods and health preservation. Traditional Chinese medicine comes from Taoism, also known as Xinglin. You can see old Chinese medicine practitioners and Taoist priests who are good at maintaining longevity.
