In a recent film with a background in the Qing Dynasty, there was a shot of a male protagonist smoking cigarettes, and cigarettes had not yet appeared in that era. However, because the moviegoers obviously didn't care about these, for most movie audiences, This mistake obviously does not affect any historical authenticity revealed in other aspects of the film. If correct, the one that would most undermine the above conclusions is:. ['Although the film describes many events that have not experienced historical confirmation, it has been praised for its reasonable description of historical events.', 'The movie scene showing the actor smoking a cigarette is a scene that is crucial to the plot of the movie, and some of the scenes are shown for the second time in the flashback.', 'Historical filmmakers often compromise between the authenticity of history and the need to keep the material acceptable to modern audiences, much like the way actors speak.', 'A previous film depicting the Tang Dynasty shows a scene of an official smoking a cigarette, a historical error mocked by many popular film reviews.']
