In the Romance of Gods, the dragon kings in the East China Sea are Ao Guang, Aoshunlong in the South China Sea, Aominglong in the North China Sea and Aojilong in the West China Sea. In the fairy mirrors of past dynasties, their names were longer and thinner. They are Wang Aoguang of Ningde in the East China Sea, Wang Aoqin of Shengji in Ganlong in the South China Sea, and Wang Aoqin of Xunze in the North China Sea. In Wu Cheng'en's Journey to the West, the Monkey King of Huaguoshan killed the Dragon Palace of Ao Guang, the dragon king of the East China Sea, and found some weapons and got a golden hoop. After I got this magic weapon, I was still not satisfied. I asked Aoqin, the dragon king of the South Sea, for a purple crown with phoenix wings, Aorun, the dragon king of the West Sea, and a set of walking shoes with lotus roots.
