text: Wong is the martial arts instructor of the local militia in Foshan. He also runs his own traditional Chinese medicine clinic, Po-chi-lam, and has three apprentices: "Porky Wing", "Bucktooth" So, and Kai. He meets Siu-kwan, the daughter of a sworn brother of his grandfather. Even though she is around the same age as him, he still has to address her as "13th Aunt" as she is considered more "senior" than him. They have romantic feelings for each other but their relationship is restrained because it is taboo in the conservative Chinese society of their time.
  Leung Foon arrives in Foshan with an opera troupe to stage performances. He encounters 13th Aunt by chance, has a few clumsy encounters with her, and develops a crush on her. He also runs into trouble with the Shaho Gang, which terrorises and extorts money from local businesses. A fight breaks out between the gang and the local militia while Wong is meeting the Governor of Foshan in a restaurant. The gangsters flee when they realise they are no match for Wong. The Governor blames Wong for the disturbance, and disbands and arrests the militia members. Wong confronts the Shaho Gang's leader, defeats him and captures him, but the authorities release him because no one wants to help Wong by testifying as a witness in court.
