Cui Shu was a scholar of textual criticism during the Qianlong and Jiaqing reigns who did not share his work with the broader scholarly community. Comparing the similarities and differences in research methodology and academic thought between Cui Shu and Han scholars, the author concludes that Cui Shu was not a typical representative of Qing dynasty textual research and that his ideas should not be carelessly included under the rubric of Han Learning. Cui Shu carried on Zhu Xi’s tradition of textual criticism but his method did not mark a significant departure from the Song approach to textual criticism.
