This case study deals with late Chosŏn dynasty works of narrative fiction modelled after Kuunmong (A Dream of Nine Clouds) by Kim Manjung (1637–1692). The focus lies on a novel extant in two manuscripts: Sinjŭng Kuullu (Revised augmented edition of the Nine Cloud Tower) and Sinjŭng chaeja Kuun'gi (Revised augmented caizi edition of the Story of Nine Clouds), short Kuullu/Kuun'gi. While this study specifically discusses late premodern hypertexts of Kuunmong, it is also concerned with a set of broader questions regarding the diffusion, circulation, reception, and creative transformation of literary products of different languages on the eve of modernity in Sino-centric East Asia.
