This film tells the story of the adventures of Huang Feihong, a master of the generation, in his youth. In the early years of the Republic of China, the young Huang Feihong (played by Jackie Chan) taught himself a set of powerful boxing techniques - drunken boxing. However, every time he used this set of boxing techniques, he had to get drunk first, and use the drunken state to break all the laws of martial arts to exert the power of drunken boxing. Because of this, Huang Feihong's father Huang Qiying strictly prohibited his son from practicing this boxing technique that was unrefined and violated the rules of practicing martial arts to strengthen the body. The young and naughty Feihong often practiced drunken boxing behind his father's back, and defeated many strong players with it. On this day, Feihong and his father went to the northeast to do business together. Halfway, the father and son met a group of foreign robbers who secretly smuggled the national treasure jade seal out of the country. In order to stop this group of robbers and take back the national treasure, Feihong had to use his specialty - drunken boxing!
