Southern Sòng 宋 official, classicist and Yǒngjiā-affiliated 永嘉 thinker, native of Xīnchāng 新昌 in Shàoxīng 紹興 (Zhèjiāng). Zì Wénshū 文叔; posthumously canonized Xuānxiàn 宣獻. Lifedates 1138–1213 are firm (CBDB id 24717). He passed the jìnshì during the Shàoxīng 紹興 era (i.e. before 1162), entered the censorate, and famously impeached the autocratic chief councillor Hán Tuōzhòu 韓侂胄 (1152–1207); under Níngzōng 寧宗 (r. 1194–1224) he rose by stages to Lǐbù shàngshū 禮部尚書 (“President of the Ministry of Rites”) and Lóngtúgé xuéshì 龍圖閣學士. In his late career he was sent out as zhìkǔn 制閫 — military commissioner over the JiāngHuái 江淮 defense — during the Jīn 金 wars, and Chén Zhènsūn’s Zhízhāi shūlù jiětí 直齋書錄解題 records that even at the front he “did not stop writing; whenever he hit upon a new reading he would knock at his friends’ study doors at all hours of the night to discuss it.” A learned friend of 朱熹 (1130–1200), Yè Shì 葉適 (1150–1223), and Chén Fùliáng 陳傅良 (1141–1203) — both of the latter being core figures of the Yǒngjiā shìgōng 永嘉事功 school — Huáng Dù wrote substantially on the Yìjīng 易經, the Shī jīng 詩經, and the Zhōulǐ 周禮 (his Zhōulǐ shuō 周禮說 and Shī shuō 詩說 were both publicly endorsed by Yè Shì), but his Shàngshū shuō 尚書說 (KR1b0014, in 7 juǎn) is judged the most distinguished of the lot — read not as Han-style zhāngjù 章句 but as a sustained meditation on the rise and fall of the Three Dynasties and on the imperial duty of “holding to the mean and establishing the ultimate” (執中建極).
