The Private Eyes (1976)

Respect for people with connections in high places is so great in Chinese society that a simple newspaper photo of the head of the Manix Detective Agency shaking hands with an important government official is enough to win him scores of clients, though his track record is somewhat spotty. Despite this, he has enough work to consistently get into a lot of trouble in the most unexpected places (i.e., a supermarket). He has double the fun when he hires a young man who was fired from his job in a bottling factory for practicing kung fu on soda bottles.
