CEVAP:

An important aspect of Chinese religion, whether Taoism, Confucianism, or Buddhism, was known as hygiene schools that instructed people on how to take care of themselves to live longer lives or even achieve immortality. Hygiene schools were part of the temple or monastery. The priests taught people how to eat healthy, exercise (the practice of Tai Chi developed through these schools), and perform rituals honoring the gods so the gods would bless them with a healthy long life.
