ORIGIN
The concept of Yin and Yang became popular with the work of the Chinese school of Yinyang which studied philosophy and cosmology in the 3rd century BCE. The principal proponent of the theory was the cosmologist Zou Yan (or Tsou Yen) who believed that life went through five phases (wuxing) – fire, water, metal, wood, earth – which continuously interchanged according to the principle of Yin and Yang.
