Wu Cheng'en
Erlang makes an appearance near the start of the classic "Journey to the West" by Wu Cheng'en. Erlang, who is titled as being either True Lord or Illustrious Sage, is the nephew of the Jade Emperor. Erlang made his first appearance when he had been ordered by the Jade Emperor (in which Erlang was also with his seven elite sages whom he called his brothers) to subdue Sun Wukong, who was to be punished for his havoc in heaven.
