The Spiritual Boxer

Acclaimed action director Liu Chia Liang makes a mind-boggling directorial debut in The Spiritual Boxer, which not only quickly established Liu as a genius director but he was also credited with introducing comedy into the Kung Fu genre; the pre-cursor for Jackie Chan's Kung Fu comedies. Its Ghostbusters meets George C. Scott's The Flim-Flam Man as a pseudo-ghost catcher, wittily portrayed by Kung Fu comedienne Wang Yu, and catches more than he bargained for.
This con artist uses Kung Fu to swindle villagers for money by pretending to be possessed by angry gods. However, when the villagers are later threatened by bandits he must use the same skills for good.
