Despite a 11-year age difference between them, Patrick Tse and Josephine Siao made up one of the most popular screen couples in the late 1960s. In this adaptation of Yee Tat's novel, Siao plays a decadent prostitute, initially disguised as a privileged heiress and later revealed to be a dutiful daughter. Equally impressive is Tse as a writer who stays by the heroine's side through thick and thin. Unlike most Cantonese films at the time, director Chor Yuen left the studio and chose to shoot much of the film in real locations, providing a real wintry look that fits the film's title perfectly.
