Zui hou nu
The story of Ming Ling Shur, a girl who was raised by apes and thus has a natural ability with monkey kung fu. She also resembles a monkey for most of the film (not really explained why). She grows up and falls for a prince who is really an evil kung fu master, who exploits her abilities for his own gain. Now here's why the film works; Kam Fung does an excellent job as the Ape Girl, being very eccentric at times with the actions of a monkey. Also, we see early performances by Lo Lieh as an assassin, and Chen Sing as the prince.
