Late-Míng 明 Shàngshū philological note-taker, native of Jiāxīng 嘉興 (modern Zhèjiāng). Zì Tóngqiàn 同倩. Lifedates not securely recorded; floruit Wànlì 萬曆 era (1573–1620). Per Wú Yǒngfāng’s 吳永芳 Jiāxīng fǔzhì 嘉興府志 he was a Guózǐjiàn shēng 國子監生 (registered student of the Imperial Academy, without further metropolitan-examination success).
He must be sharply distinguished from his close contemporary Chén Tàilái 陳泰來 (zì Chángshuǐ 長水, of Pínghú 平湖, Wànlì 5 / 1577 jìnshì, eventually Lǐbù Jīngshànsī yuánwài láng 禮部精膳司員外郎). Zhū Yízūn’s Jīngyì kǎo 經義考 conflated the two, attributing the Shàngshū zhù kǎo 尚書註考 to Chén Tàilái; the Sìkù tíyào on the work (KR1b0042) explicitly disambiguates and corrects the attribution by citing Xiàng Gāomó’s 項臯謨 testimony in the Jīngyì kǎo itself (“Tóngqiàn applied himself to the Shàngshū and composed the Zhù kǎo”) — Tóngqiàn being Chén Tàijiāo’s zì, not Chén Tàilái’s.
His one Shàngshū work, the Shàngshū zhù kǎo in 1 juǎn, is a methodologically narrow but evidentially careful philological survey of Cài Shěn’s Shū jízhuàn (KR1b0017): it catalogs three cases where Cài’s intra-canon citations are inconsistent with the canonical text itself, and 323 cases where Cài glosses the same character with multiple distinct meanings in different passages.
