Hé Zhuō 何焯 (1661–1722), zì Qǐzhān 屺瞻, hào Yìmén 義門, also Cháxiān 茶仙, foremost Kāngxī-era philological textual critic and bibliographer. Native of Chángzhōu 長洲 (Sūzhōu, Jiāngsū). Did not pass the jìnshì but was admitted to the Hànlín by special imperial favour as shūjíshì 庶吉士 in Kāngxī 41 (1702), then biānxiū 編修 — his jìnshì-equivalent status was conferred by the emperor on the strength of his scholarly reputation alone. Tutored the eighth imperial son Yìnsì 胤禩, which led to his disgrace and brief imprisonment late in Kāngxī’s reign. CBDB id 66023; Qīng shǐ gǎo j. 484. Restored posthumously.
His scholarly authority rested on his collation-and-correction (jiào kān 校勘) of countless rare Sòng and Yuán editions assembled in his Yìmén tángzhōng 義門堂 collection: his marginalia in those collated copies were after his death gathered as the Yìmén dúshū jì 義門讀書記 (52 juan, ed. Jiǎng Pán 蔣枻) and form the foundational reference for early-Qīng kǎozhèng-style book-criticism. He worked on multiple late-Kāngxī imperial compilations as collation officer — including KR2j0002 Yùdìng yuèlìng jíyào, where he is listed among the jiào duì guān 校對官. His textual judgments on the Wén xuǎn 文選, the Hàn shū 漢書, the Three Histories, and TángSòng poetry collections were subsequently quarried by Qián Dàxīn 錢大昕, Lú Wénchāo 盧文弨, and the broader QiánJiā kǎozhèng tradition.
