Spiritual Boxer (1975)

Lau Kar-Leung's directorial debut was apparently the first film that could be classed as a "Kung Fu Comedy", and was clearly an influence on Jackie Chan and Sammo Hung (particularly Drunken Master and Encounters Of The Spooky Kind), but fails to be as enjoyable as those two classics for whatever reason. Well, the main reason is that Wong Yu doesn't have the charisma or comedic ability of either of the Golden Harvest luminaries - and the fact that the film is in Mandarin doesn't help him (the language is simply not as well suited to broad comedy as Cantonese, IMO). He's a good enough martial artist though, and the film is most enjoyable when he's being possessed by various spirits and fighting in their styles. In between, it's good enough but not "classic" level.
