The isorhyme is an important part of Chinese phonology research. The research into Chinese isorhymes performed in the Korean Peninsula is also no less important, especially from the perspective of East Asian Linguistics. It is of great value to understand the content of isorhymes in the Korean peninsula for understanding the development of isorhymes abroad. By collecting and sorting the research materials on Korean isorhymes and phonology in the past 50 years, this paper analyzes the characteristics and values of studies on Chinese isorhymes in the Korean Peninsula. It summarizes the application of ancient phonology theory, the study on a phonological model of Shengyin Changhetu (《聲音唱和圖》 ), Qieyun (《切韻》 ) and related rhyme books, and studies on rhyming in the three dynasties of Song, Ming, and Qing. In the final analysis, it is concluded that considering the history and current situation related to the studies on Chinese isorhyme in the Korean Peninsula, the fundamental research into the equivalence prosody is of great value.
