The Chinese philosophy of Taoism (or Daoism) developed in the latter part of the Chou Dynasty, during a period of turmoil in which it was not clear that Chinese civilization would survive.
Because Daoism was suppressed in 20th century China it is hard to discover how many people follow the tradition. Estimates vary from 20 to 400 million people. Traditional Chinese Medicine (TCM), which is the most widely practised medical tradition in the world, was developed from Daoist principles.
