This paper is based on Ji Yun's Shenshi Sishengkao.It is divided into four parts:The first section of the first chapter introduces the research object of this topic,including the author of the Shenshi Sishengkao,the background of the book and the author's main purpose of writing this book.The second section uses the extraterritorial literature to explore the nature of Shenyue's Sishengpu.The conclusion is that the Sishengpu is not a necessarily rhyme book.The third section introduces the research purpose,significance and research methods of this topic.The second chapter makes an in-depth analysis of the text of Shenshi Sishengkao,according to the shenyinhouji and the Song Ben's Guangyun we checking Jiyun linked rhyme word,and we compared with Jiyun's examination about the unique use and same use of Shenyue's rhyme and Dai Zhen testing the Guangyun unique use and same use of four sound table".We found that the idea of "Four-voiced voice system"is the whole story of Shenshi Sishengkao.As the same period of Ji Yun,Wan Guangtai also made a special test on the use of rhyme in Shen Yue's rhyme,and he writting the book of Sishengpu Kaolue.Therefore,we compare the results of the two examinations in the third chapter.We believe that although the Shenshi Sishengkao is a testimony,it has a solid theoretical foundation of phonology."The division of rhyme,there is rhyme to test;In the case of the Ministry,there are similar users.”Ji Yun's academic thoughts and analytical strategies are still instructive for us to understand the phonological nature of Qieyun.Through in-depth study of Ji Yun's Shenshi Sishengkao,we have obtained some valuable academic achievements.In the conclusion part,we fully affirmed the value of the Shenshi Sishengkao in academic history,and also pointed out some problems in the study of Ji Yun.
