Chusheng Cai - A Dream in Pink AKA Pink Dream AKA Fenhongse de meng (1932)

Here is one of Cai Chusheng’s earliest films, set in and around the dancehalls of art deco Shanghai.

Plot, per wikipedia:
Pink Dream tells the story of a young novelist who is supported by a loving and hard-working wife. The novelist, however, is drawn to the decadent life of a socialite who introduces him to the dance halls that dot Shanghai. As the film progresses, the novelist soon learns of the emptiness of this urban existence and rejects it as a “pink dream.”
