Why is there a clear difference between the movie version of White Deer Plain and the original novel?

There were obvious differences between the movie version of White Deer Plain and the original novel mainly because of the huge differences in story, characters, and plot. The following are some of the main reasons that may lead to discrepancy: 1. The difference in the storyline: The original novel and the movie version have very different storylines. The original novel told the love story between Bai Ling and Lu Zilin, but the movie version compressed the story into a more compact time frame and highlighted the brotherhood between Lu San and Lu Zhaohai. 2. Different characters: The main characters in the original novel, such as Lu Zilin, Bai Ling, Lu San, etc., have also changed greatly in the movie version. The movie version highlighted the characters of Lu San and Lu Zhaohai, while the relationship between Bai Ling and Lu San in the novel was more complicated. 3. Different scenes: The movie version has made some adjustments in the scene reproduction to adapt to the movie's presentation. For example, some scenes in the novel were deleted or adapted into other plots in the movie. 4. Different shooting techniques: The film version uses more modern shooting techniques such as special effects and editing. These techniques may affect the understanding of the story and the image of the characters. The difference between the movie version and the original novel was mainly due to the differences in storyline, character creation, scene reproduction, and shooting techniques. These differences might cause the audience to have a different understanding of the movie and the novel.
