Description：Aqiang (Sang Weilin) has been learning Chinese martial arts since he was a child, and won the title of champion in a martial arts competition. However, since then, his martial arts career has stagnated. It seems that he is afraid that the only first prize will be taken away. Aqiang gave up participating in the competition and just worked as a martial arts coach for children in the village. One day, Aqiang met a disabled girl named Xiaoyu, who strongly encouraged Aqiang to leave the village and take a look at the outside world. Xiaoyu's words awakened Aqiang, so he went to Shenzhen with his good friend Xiazai (Li Tie). In Shenzhen, Aqiang met the singer A Ling (Ni Jingyang), and was beaten by A Ling's brother-in-law Zhao Wei (Teng Jun) in a misunderstanding. Afterwards, Aqiang found his good friend A Long (Zhao Zilong) to seek help from him, but unexpectedly learned that A Long's father was a senior Sanda.
