Wáng Yǐnzhī 王引之 (1766–1834), zì Bóshēn 伯申, hào Mànqīng 曼卿, was the son of 王念孫 Wáng Niànsūn and continued the Gāoyóu philological tradition. Jìnshì of 1799, he rose to libu shàngshū 禮部尚書 under the Dàoguāng emperor. His Jīngyì shùwén 經義述聞 and Jīngzhuàn shìcí 經傳釋詞 are the canonical Qīng treatises on classical Chinese grammatical particles. The Wáng father-son corpus is the principal model for the late-Qīng evidential method applied to the medical classics by 俞樾 Yú Yuè (KR3ea034) and 胡澍 Hú Shù (KR3ea006).
