Wong Tai Sin is a Taoist God who achieved fame using the miraculous properties of Chinese herbal prescriptions in aiding the needy and healing the sick. He has gained respect by preaching benevolence and practising virtues, while possessing the power to control "benevolence prevails upon request". Therefore, he is very popular among peasant worshippers.

Legend says that Wong Tai Sin was originally named Wong Cho Ping. He was born in A.D. 328 and was a shepherd boy living in the Red Pine Hill, north of Jinhua in Zhejiang Province. When he was 15 he was taught by an immortal the art of refining cinnabar into a medicine that was said to cure all illnesses. He spent the next 40 years living in seclusion until he was found by his brother.
