Crazy Stone (2006)

Mongolian Pingpong director Ning Hao weaves this tangled heist tale concerning a priceless piece of jade, and the bumbling thieves willing to do whatever it takes to assume ownership of the gem. The owner of a dilapidated factory has discovered a valuable piece of jade on his property, and now in order to keep a greedy real-estate developer at bay he's looking to find a buyer for the stone. Until that happens, however, the factory owner has determined to put the stone up for display at a run down temple so that potential buyers may admire its beauty. In order to protect the stone, the factory owner assigns hardworking assembly-line worker and former detective Bao (Guo Tao) as his head of security. Now, if Bao can only put his prostate troubles aside long enough to keep three thieves, a skilled burglar hired by the scheming real-estate developer, and the son of the factory owner away from the stone, he may be able to ensure that the factory remains open and he still has a job at the end of the day.
