This film is about an adventure in the youth of Huang Feihong, a generation of guru. At the beginning of the Republic of China, the young Huang Feihong (Jackie Chan) taught himself a set of powerful boxing-drunken boxing. But every time we play this set of boxing, we must first get very drunk and use drunkenness to break all the laws of martial arts in order to give full play to the power of drunken boxing. Because of this, Huang Feihong's father, Huang Qiying, strictly forbade his son to practice this kind of boxing, which is harmful to style and violates the law of practicing martial arts and strengthening the body. The naughty young Feihong often practiced drunken boxing behind his father's back, thus defeating many strong players. On this day, Feihong and his father went to the northeast to run errands. On the way, father and son met a group of foreign robbers who secretly smuggled the national treasure and seal out of the country. In order to stop the robbers and take back the national treasure, Feihong had to use his unique skill-drunken fist!
