Xu Anhua's adaptation of Zhang Ailing's Love in a City-Toppling City was different from the original work in the following aspects: 1. There are differences in the plot and character creation between the movie and the original novel. The movie had edited and adapted some of the plots in the novel to adapt to the narrative and shooting conditions of the movie. For example, in the novel, Fan Liuyuan and Bai Liusu's relationship after the Qingcheng incident was cut, but in the movie, this plot was placed at the end to explain the ending of the whole story. There were also differences in the theme between the movie and the original novel. The original novel mainly explored the emotions and fates of the characters in the city-toppling incident during the civil war, emphasizing the power of love and family. The movie shifted the theme to the discussion of human nature, paying more attention to the psychological description of the characters and the turning point of the story. For example, in the movie, Bai Liusu explored the complexity and contradiction of human nature more deeply when she faced the choice between the civil war and the responsibility of the country. As a result, Anhua Xu's adaptation of Eileen Chang's " Love in a City-Toppling City " was quite different from the original work. Although the film had been adapted and deleted from the original work, it paid more attention to the psychological description of the characters and the plot twist, making the film more in-depth and enjoyable.
