Martial Club (1981)

Wong Fei Hung (Gordon Liu) and his friend are constantly having contests to see who has the better martial arts skill. After getting in trouble with their fathers, Wong Fei Hung settles down and starts to train seriously, while his friend still horses around. After his friend is hurt by a rival school, Wong goes to the school for retribution. Instead his skill is tested through a series of events which climax with him taking on a Northern martial artist (Wang Lung Wei). In an excellent battle of skill (and choreography), he earns the respect of the rival school. Also stars Mai Te Lo and Hui Ying Hung.
