Ao Guang (; or ) is the Dragon King of the East Sea in Chinese folklore. He featured prominently in different works including Fengshen Yanyi and Journey to the West. Fengshen Yanyi According to the Fengshen Yanyi, after the passage of many years, Ao Guang had brought chaos to the world by creating droughts, storms, and other disasters. Due to the people's immense fear of the dragon king and his sons, they never dared seek protection against him from the Jade Emperor. As a result, Ao Guang enjoyed countless offerings by the people throughout a time interval of many years. One day, Nezha cleansed himself at a neighboring stream of the East Sea, causing Ao Guang's palace to shake at an annoying level. After Ao Guang's favorite investigator Li Gen and third son Ao Bing were both killed by Nezha, Ao Guang set out to talk to Nezha's father, Li Jing. Ao Guang demanded that Li Jing offer himself as a sacrifice to atone for Nezha's actions, but Li Jing refused. After a long discussion on the matter, Ao Guang, by now extremely angry, ascended to the heavens to state the issue to the Jade Emperor. However, Nezha, having opted to sacrifice himself in his father's place, appeared in heaven and began to beat Ao Guang very violently, even tearing scales from his skin and causing him to bleed. Ao Guang was forced to turn himself into a small snake and come with Nezha back to the Old Pond Pass to forget about the incident completely. Later, Ao Guang, along with three other dragon kings, came to Old Pond Pass and took both Li Jing and his wife Lady Yin. Nezha, wishing to free them, offers the dragons all of his internal organs in exchange for his parents. Ao Guang personally agreed to Nezha's resolution with happiness and brought his internal organs to the Jade Emperor. After this point, Ao Guang's fate is unknown. Journey to the West In Journey to the West, the monkey king Sun Wukong obtained his Ruyi Jingu Bang, a magically expanding, gold-ringed iron rod weapon, from Ao Guang. This weapon was originally a tool for measuring the depth of sea water used by Yu the Great in his flood control and treatment efforts; hence its ability to vary its shape and length. After Yu left, it remained in the sea and became the "Pillar holding
