Erlang Shen

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 second son of a mortal and Jade emperor's brother. In the legend, he is known as the greatest warrior god of heaven.

Of the various identifications of Erlang Shen the most common is as Li Erlang, the second son of Li Bing, the engineer behind the Dujiangyan irrigation system.

According to the "Story about Li Bing and His Son in Harnessing the Rivers" in Records of Guansian, Li Erlang assisted his father in the construction of the complex irrigation system that prevented the Min River from flooding and irrigated the Chengdu Plain. In thanks for the prosperity that this brought to them the local people elevated the father and son to gods and dedicated the Two Kings Temple to their honour.
