* FairForItsDay - Despite the YellowFace and the racial slurs, Chen Huan (and the Chinese community in London generally) is depicted positively. And of course Chen is the hero of the story.
* UnfortunateImplications - Chen is played by a white man in YellowFace, as was routine for films of the time (The practice remained common at least until the 1970's, and has not entirely been abandoned to this day.)
* ValuesDissonance - Though he is an unambiguous hero, Chen is mostly referred to, even in narration, as a "Chink", or a "Yellow Man".
* TheWoobie:
** Lucy in all her life was a servant to her abusive father. When she does her [[TheUnSmile un-smile]], the narration notes that she never had a cause to smile genuinely. When she finally meets a man who's nice to her, [[spoiler:she's murdered by her father because of it.]]
** Chen, who has to see his ideals destroyed, and [[spoiler:the girl he loved killed - partially because of him.]]
