There is no limit to the number of characters in the novel, but only a limited number of people can appear on the play stage. Also, novels can contain vast amounts of content, but they must deliver certain content within a set time. The ultimate purpose of this study is to examine how characters in Hongloumeng are reconstructed and reinterpreted in the performance contents. This paper studied Cantonese Opera The Romantic monk to see how Baoyu’s character is reinterpreted in modern performance content. The features of these aspects can be summarized as follows : First, in terms of contents, a few of narratives related to the love of Baoyu was adopted from the original work. Second, in setting up the character, Baoyu was reinterpreted as the main character of pure love. He was transformed into a man of pure love who loves only one and practices his oath only for one person, eliminating the indecisive character shown in the original book. Third, regarding psychological description, Baoyu’s psychology, which was not reflected in the original work, was faithfully supplemented.
