Yunqi Chuhong, one of the four eminent monks in the late Ming Dynasty, advocated the method of reciting Buddhism. Chu-chuang Sui-pi is his reading notes, which not only involves character comments, covers ancient and modern monks and lay figures, but also is rich in content. The reading notes cover the character’s comments that represent the author’s values, comment principles and comment perspectives. This article is the preliminary result of the author’s discussion on the characters’ comments in Chu-chuang Sui-pi. Yunqi Chuhong inherited Sima Qian’s character commentary, and also provided different perspectives such as Buddhist karma and fruit, which made the commentary of historical figures more diverse and in-depth, and developed a new style of character commentary.
