The Water Margin, also known as "Outlaws of the Marsh," is a classic Chinese novel that typically contains 100 chapters in the original text. However, when adapted for Chinese language textbooks, the number of chapters can vary. In most Chinese language textbooks, the novel is abridged and divided into a fewer number of chapters to suit the curriculum and level of the students. Commonly, textbooks might include 20 to 30 chapters from the original text. This abridged version is designed to provide students with a digestible and manageable introduction to the story without overwhelming them with the extensive content of the original novel.

The reason for this abridgment is primarily pedagogical. Textbooks aim to simplify complex texts for language learners, focusing on key themes, characters, and plot elements that are most relevant to the learning objectives. By reducing the number of chapters, educators can ensure that students have a clear understanding of the story's structure and can practice language skills such as reading comprehension, vocabulary building, and grammar without being overwhelmed. Additionally, the abridged versions often include annotations and footnotes that help explain cultural references and historical context, making the text more accessible to learners who may not be familiar with the original source material.

For example, the "New Concept Chinese" series, a widely used textbook for Chinese language learners, includes a selection of chapters from the Water Margin. In this particular textbook, the novel is divided into approximately 20 chapters, which is a moderate abridgment that allows students to engage with the story while also developing their language skills. This approach is consistent with the broader trend in language education, where abridged versions of classic texts are used to cater to the needs of learners at different proficiency levels.
