CID: Two Teddy Girls(1976)

"Breaking the constraints of traditional television storytelling, Tam and Chan give a surprisingly in-depth exploration into the modern female psyche, exposing their fears and their desires. In their later attempts in CID: Two Teddy Girls, the pair uses a seemingly typical cat-and-mouse chase story between a cop (Mark Cheung Lui) and two criminal "teddy girls" (Ban Ban and Marysia Lam) to portray the lives of Hong Kong's different social classes.
