The Young Avenger(1972)

Overview:

After a career spanning more than forty years and dozens of films as director or writer, Yueh Feng used everything he learned on a final few martial arts epics, of which this is one of the most memorable. It's not easy to forget a hunchbacked, one-armed protagonist, nor the "Poisonous Dragon Sword" style, nor the luminous and lethal Shih Szu as the title swordswoman, who is out to avenge her father's death at the mid-autumn festival.
