Любовь и долг (1931)

Love and Duty is a 1931 Chinese silent film, directed by Bu Wancang and starring Ruan Lingyu (Lily Yuen) and Jin Yan (Raymond King). Though very successful upon initial release in China, the film was then lost for decades before it was rediscovered in Uruguay in the 1990s. It is now housed at the Taiwan Film and Audiovisual Institute. The melodrama stars Ruan Lingyu, portraying two different characters in the film: the mother, Yang Nei Fan, and Huang Koon Ying, Nei Fan's daughter. For shared scenes, split screen technology is used to make both characters appear on screen at the same time.
