With the compilation of Chu Ci by Liu Xiang and the popularity of Wang Yi's Annotations on Chu Ci,the scope and concept of Chu Ci between the Han and Song dynasties were essentially defined by Chu Ci.However,during the Song dynasty,there was a transformation in the textual(bibliographical)aspect of Chu Ci studies.Scholars such as Chao Buzhi and Zhu Xi broke free from the constraints of previous editions,not only expanding the range of Chu Ci texts but also reshaping the concept of Chu Ci.They actively broadened the category of Chu Ci literature,essentially undertaking a reconstruction of Chu Ci.The innovative textual ideas presented in Song dynasty Chu Ci studies directly contributed to the diversification of Chu Ci studies during the Yuan,Ming,and Qing dynasties,and to some extent,influenced the development of modern Chu Ci studies.
