Ao Xue is the little princess of the Dragon Palace of the East China Sea. She is born with magical powers and can control the wind and rain. The Dragon King's father arranged a marriage for her, and the other party was the third prince of the Dragon Palace of the West Sea. Ao Xue didn't want to get married. She said, "I am the Dragon King, not anyone's wife." She escaped from marriage and went ashore, using the pseudonym "A Xue" and working as a swimming coach at a seaside primary school. She taught children how to swim, save lives, and silently helped fishermen predict typhoons. The third prince chased him ashore, but was beaten back by Ao Xue. The Dragon King came to persuade him personally, and Ao Xue said: "Father, I can inherit the Dragon Palace, but I will not marry anyone. I want to use my ability to protect this sea and the people on the seaside." The Dragon King looked at his daughter's stubborn eyes and finally nodded.
