Wáng Niànsūn 王念孫 (1744–1832), zì Huáizǔ 懷祖, hào Shíqú 石臞, was a major QiánJiā-era philologist of the Gāoyóu 高郵 school, pupil of 戴震 Dài Zhèn, and the principal continuator (with his son 王引之 Wáng Yǐnzhī) of the Hàn-philological revival in the late 18th and early 19th centuries. His Guǎngyǎ shūzhèng 廣雅疏證 and Dúshū zázhì 讀書雜志 set the methodological standard for phonetic-loan, graphical-variant, and intertextual-citation argument used by later scholars including 俞樾 Yú Yuè and 孫詒讓 Sūn Yíràng on the medical classics (KR3ea006, KR3ea034).
