ABSTRACT
Su wen shi yi (Annotated Plain Questions), compiled by Zhang Qi in the 9th year of Daoguang reign, was an important revised edition of Su wen (Plain Questions) which has over 570 entries of revised texts. Among them, about a half was inferred proofreadings which is a unique point of this book. This is closely related to the prevalence of scholastic atmosphere of textual research at that time. During his inferred proofreading, Zhang checked the original texts of Plain Questions and Wang Bing's texts as well. The exact method for his inferred proofreading included checking based on the original texts, checking based on medical doctrines, and combined method of both. The inferred proofreading method is of high reference value, exerting certain influence on the studies of Nei jing (Inner Canon) both domestically and abroad.
