There is a golden dragon carp in the pond in the backyard of Lu Changsheng's home, and his daughters often play with it. One day the Dragon King of the East China Sea came to the door: "Give me back my son Ao Bing!" The daughters were confused: "Isn't that our fish?" The Dragon King was furious and wanted to flood the manor, but was driven back thousands of miles by his eldest daughter with a sword. Lu Changsheng brought out steamed dragon carp (ordinary fish) to treat him: "Misunderstanding, really a misunderstanding." At this time, Ao Bing jumped out of the pond: "Father! I work here, and the master feeds me Creation Green Lotus every day!" Before the Dragon King fainted, he had only one thought: What is the background of this family? !
