Fish and Hua Wuque are two main characters in Tian Ba Long Department by Jin Yong. Xiaoyuer is a gentle, intelligent and studious woman, who comes from a family like her nickname "Sanmen God". At the age of thirteen, she was injured by Li Mochou (her cousin) because of an accident, and then she ran into Hua Wujue, the teacher of "Jiuyang Zhen Jing" in Hong Qigong. Between demonism and Wulin, Xiaoyuer made a hard choice, played what he had learned and became the backbone of Wulin in the Central Plains. Hua Wuque is a generous, open-minded and cheerful hero and a disciple of Quanzhen Sect. When I was treating Master Hong Antong, I met the little dragon girl and fell in love with her deeply. I once blamed myself for hurting my master by trusting others' words by mistake. In order to avoid being hunted, he and the little dragon girl chose to live in seclusion for three years, during which they became husband and wife. After all kinds of twists and turns, parting from life and death, repenting and turning over a new leaf, Hua Wuque became one of the most powerful chivalrous men, firmly safeguarding the peace of Wulin.
