King Father of the East, also known as Dongwanggong (東王公), is the tutelary deity of the Taoist immortals.
[4] When the Queen Mother of the West (Xiwangmu) was a mountain demon, she was in love with the King Father of the East (Dongwanggong).
[2] The Book of Gods and Wonders (神異經) describes him as a white-maned being, again with a bird's face and tiger's tail, mounted on a black bear.
[6] Many Taoist mythological works describe him as born of the Pure and the Holy Mother of Origins, ruling the animated beings and the yin and yang that breathes from the eastern sky.
In the tradition of the alchemists, Quanzhen School, in particular, Wang Xuanfu, master of Zhongli Quan and first of the Five Ancestors of the North, is his avatar, according to Lü Dongbin.
