Erlang Shen (二郎神), or Erlang is a Chinese God with a third truth-seeing eye in the middle of his forehead.
Er-lang Shen may be a deified version of several semi-mythical folk heroes who help regulate China's torrential floods, dating variously from the Qin, Sui and Jin dynasties. A later Buddhist source identify him as the second son of the Northern Heavenly King Vaishravana.
In the Ming semi-mythical novels Creation of the Gods and Journey to the West Erlang Shen is the nephew of the Jade Emperor. In the former he assisted the Zhou army in defeating the Shang. In the latter, he is the offspring of a mortal and the Jade Emperor's sister.
