Fatso Married Skinny(1956)

Lai-ying (Cheng Bik-ying) is a wealthy socialite who travels globally. Tired of her lifestyle, she sends her secretary Kiu (Tam Lan-hing) to stand in for her in a social function in Hong Kong. Local rich playboy Chung (Sun Ma Si-tsang) is forced by his father (Lee Hoi-chuen) to court the fake Lai-ying in order to save the family from financial distress. But Chung is in love with the real Lai-ying, who pretends to be a poor girl from a working class background. Naturally, the father is unhappy about this mismatch. Typically cast for feisty roles, Tam Lan-hing here plays a marriage-hungry woman, eager to be seduced who knows flirtatiousness can be so hilarious!
