Huang Qiying, a famous martial arts celebrity in Guangdong, has strictly trained his son Huang Feihong (Jackie Chan) to practice martial arts since he was a child. Unfortunately, Huang Feihong was young and vigorous when he was a teenager. He often used three-legged kung fu to make trouble outside, and he has not made great progress in martial arts. It was not until he was beaten and insulted in a contest that Huang Feihong vowed to worship Su Qier (Yuan Xiaotian) to practice martial arts. Because Su Qier was lazy in accepting apprenticeships and distrustful of Huang Feihong's character, he offered all kinds of harsh conditions. In order to show his determination, Huang Feihong agreed to them one by one and worked hard to realize them all. Finally, he sincerely moved Su Qier and made him teach him drunken boxing. Huang Feihong gradually grew from a reckless teenager to a young man who acted bravely for righteousness.
