Hú Yuán 胡瑗
Style name Yìzhī 翼之; conventionally known to posterity as Master Āndìng 安定先生 from his late residence at Āndìng 安定 in Húzhōu 湖州. Native of Tàizhōu Rúgāo 泰州如皋 (modern Jiāngsū). Lifedates 993–1059 (Northern Sòng). The most consequential pre-Chéng-Zhū yìlǐ teacher of the Northern Sòng and the architect of the so-called “Húzhōu method” (Húzhōu fǎ 湖州法) of Confucian academic pedagogy.
Recommended into office by Fàn Zhòngyān 范仲淹 from commoner status (bùyī 布衣), he passed through Jiào shū láng 校書郎 (“Editor in the Imperial Library”) and rose to Tàixué bóshì 太學博士 at the Imperial Academy under Rénzōng. His Sòngshǐ biography is in the Rúlín zhuàn (juan 432). He is one of the canonical “Sānxiānshēng” 三先生 (“Three Masters”) of the early Sòng Confucian revival together with Sūn Fù 孫復 and Shí Jiè 石介.
His distinctive pedagogical innovation at the Húzhōu academy and later at the Imperial Academy was the “Húzhōu method”: separating the jīng yì zhāi 經義齋 (“Classical-Meaning Hall,” dedicated to broad classical learning) from the zhì shì zhāi 治事齋 (“Practical-Affairs Hall,” dedicated to applied learning in arithmetic, military strategy, hydraulics, astronomy). The arrangement was a precedent for Wáng Ānshí’s later New-Policies academy reforms.
His chief surviving works on the Yì are recorded in oral form by his student Ní Tiānyǐn 倪天隱: the twelve-juan Zhōuyì kǒuyì 周易口義 (KR1a0012 — also called Yì jiě in some catalogues; the same work). Hú himself did not personally compose; the title “Kǒuyì” (“Oral Meaning”) records the redactional fact. His Hóngfàn kǒuyì 洪範口義 commentary on the Hóngfàn chapter of the Shàngshū survives separately.
His most consequential intellectual legacy is via Chéng Yí 程頤 (1033–1107), who studied under him at the Imperial Academy in the Huángyòu era and absorbed the substantive philological emendations and yìlǐ readings that Chéng then carried into his Yìzhuàn (KR1a0015). The Sìkù tiyao on Zhōuyì kǒuyì makes an explicit case — against the standard Sòngshǐ Dàoxué genealogy that traces Chéng Yí’s Yì through Zhōu Dūnyí — that Chéng Yí’s Yì derives substantively from Hú Yuán’s classroom. Through Chéng Yí, Hú Yuán’s readings shape the entire later SòngMíng yìlǐ tradition.
Zhū Xī’s Yǔlèi records his judgment: “Hú Āndìng’s Yì is clear and direct, exact and proper” (Hú Āndìng Yì fēnxiǎo, zhèngdàng 胡安定易分曉、正當).
