The film is based on a novel,
Love and Duty, by a
Polish expatriate, S. Horose, who had given the English version of her novel,
La symphonie des ombres Chinouses, to
Lo Ming Yau, the producer of the film. The producer thought that this novel, with its sophisticated plot, should be adapted to be filmed. However, he did not have enough resources. After eight years and the appearance of the
United Photoplay Service (Lianhua yingpian gongsi) in 1930, the film was finally made, which was also due to the film industry's growth. This development made the production of new types of films, like
Love and Duty, possible. In the end,
Love and Duty became one of the first films produced by the leftist United Photoplay Service. The film was very popular in its day, in no small part due to the pairing of Ruan Lingyu, a darling of the
Shanghai film industry, and Jin Yan, a Korean-born actor who was one of the major leading men in early
Chinese cinema. ==Plot==
