Li Fu, whose dates and career are unknown, is known mainly from the surviving text Kan Wu (Correcting Errors), which bears his name as author. Publicly available information about his birthplace, life, and official service is limited, so no reliable biography can be reconstructed. What can be confirmed is that one work by him is held in the collection, Kan Wu, commonly classified under Eastern philosophy. Judging from its title, the book aims to correct errors, and it belongs to the tradition of textual criticism and scholarly verification. It addresses mistakes in classical texts, terminology, institutions, and earlier interpretations, reflecting a cautious and factual approach. Though modest in length, its careful item-by-item arguments have offered reference points for later textual scholarship. Li Fu's style is concise and substantial, organized around specific problems rather than general discussion. With the available evidence, a full portrait of the author remains difficult to draw, and readers should consult the original work to appreciate its value.
