In China folklore "Eight Immortals Crossing the Sea", Prince Hualong is the seventh son of the Dragon King of the East China Sea. He does all kinds of evil. One day, wandering outside the Crystal Palace, he heard the sound of Yue Xian at sea and followed it. When he saw the Eight Immortals, especially the beautiful He Xiangu, on the dragon boat, he was attracted by the beauty of He Xiangu and had a bad idea, so he took He Xiangu away.
