Yú Zhèngxiè 俞正燮, zì Lǐchū 理初 (1775–1840), native of Yī xiàn 黟縣 (Huīzhōu prefecture, Ānhuī). Mid-Qīng Huīzhōu kǎojù (evidential-research) scholar. Author of the Guǐsì lèigǎo 癸巳類稿 (15 juǎn, 1833) and Guǐsì cúngǎo 癸巳存稿 (15 juǎn, posthumous), miscellanies of essays on a vast range of subjects — gender, foot-binding, ethnic minorities, Buddhism, Daoism, the Western legations, anatomical comparisons, etc. — written in the zhájì / lèigǎo genre with rigorous documentary citation. His essay Shū Tàixī Rénshēn túshuō 書泰西人身圖說 (on the Jesuit Description of the Human Body) is the principal target of 王學權 Wáng Xuéquán’s critique in KR3eq089 Chóngqìngtáng suíbǐ, where Wáng argues that Yú had read the Jesuit anatomical text superficially. Yú is one of the most-cited late-Imperial heterodox / proto-feminist essayists in modern Chinese-studies scholarship. Not yet matched to a CBDB id.
