Long mao shao xu (1992)

Polar Bear and Penguin are two idiot cops who seem destined to always remain constables, unlike their academy aluminum's, Senior Inspector Miss Wu. Also, their rarely-home wives are nightclub hostesses. The two are assigned to assist a cop from Borneo, Lo Raimy, who is on the trail of a witness in the prosecution of a fu-fighting Gwalior drug boss. Lo is brutally killed by the villains, and his wife comes over to complete the task, and the two bumbling cops try their best to help.
