Schindler's List was a historical novel about a German businessman, Oskar Schindler, who saved many Jewry people during World War II. Although novels have been adapted into multiple versions, there are usually only twelve chapters. This is because the story of the novel is relatively simple and the content of each chapter can be told more independently. In the 12 chapters of the novel, the reader can learn about Schindler's process of saving the Arabs, his interactions with other businessmen and government officials, and his experiences during the war. If more plots and characters were added to the novel, it might cause the story to become complicated and lengthy, which would affect the reader's reading experience. In addition, the length of the novel was also affected by the publishing company and the publishing cycle. At the time of publication, novels usually had to meet certain word count requirements so that they could be typed and edited for printing and distribution. Therefore, if the novel exceeded the specified word count, additional chapters might be needed to supplement the content. The reason why Schindler's List only had 12 chapters was because the story was relatively simple and the content of each chapter could be told more independently. At the same time, the length of the novel was also affected by the publication cycle. It was necessary to meet the word count requirements while maintaining the cohesiveness and legibility of the story.
