Where to Watch 陰忌 (1982)

Summary

On the 7th month of the lunar calendar, all ghosts and spirits are active and get to walk the earth for the month so that they can find a way to reincarnate. During one of these nights, a young kid named Chun Sing (Billy Chong), is visited by his dead Father. Chun Sing's father states that he was murdered by a man named Kam Tai Fu (Lo Lieh). And as you may have guessed, Chun Sing must avenge his father's death. It won't be easy though because Kam Tai Fu has some help in the form of a Black Magician (Ta Hsi Yen) and his evil gung fu.
