Hú Yīguì 胡一桂 (1247–1314), zì Tíngfāng 庭芳, hào Shuānghú 雙湖, of Wùyuán 婺源 in Huīzhōu 徽州 (modern Wùyuán county, Jiāngxī). CBDB id 21919: 1247–1314. Yuánshǐ biography in Rúxué zhuàn juan 189.
Son of 胡方平 (Hú Fāngpíng, third-generation Zhū-Xī-school transmission scholar; author of KR1a0062 Yì xué qǐméng tōng shì). The HúWùyuán family compound was, alongside the CàiJiànyáng family compound and the Xióng Hé Wǔ-yí-Mountain circle, one of the principal late-Sòng / early-Yuán Zhū-school Dàoxué transmission centers.
Jǔrén of Jǐngdìng jiǎzǐ (1264) at age 17. Failed the Lǐbù jìnshì examination. Subsequently devoted himself to scholarship and teaching at the Wùyuán family compound to his death (1314). Per the Yuánshǐ: “his receiving-the-Yì-source-stream is from Master Zhū” — referring to the multi-generation pedagogical line Zhū Xī → Huáng Gàn → Dǒng Mèngchéng → Shěn Guībǎo → Hú Fāngpíng → Hú Yīguì.
In 1289 (Zhìyuán 26 jǐchǒu) visited Wǔyí Mountain bringing his father’s Tōng shì manuscript for Xióng Hé 熊禾 and Liú Jīng 劉涇’s colophons-and-printing — one of the more vivid documentary moments in late-Sòng / early-Yuán Dàoxué-circle book-printing history.
Within the Kanripo corpus he is the author of:
- KR1a0069 Yì fùlù zuǎn zhù 易附錄纂註 (also titled Yì běnyì fùlù zuǎn shū 易本義附錄纂疏; 15 juan) — the principal Yuán-period Zhū-school work that maintains the gǔyì recension form of the Běnyì against the Dǒng-Kǎi-line (KR1a0061) Wáng-Bì-recension standardization.
He also authored the Yì xué qǐméng yì zhuàn 易學啟蒙翼傳 (a separately catalogued work, extending his father’s Tōng shì program; not in the Kanripo Yì lèi but cited extensively in the Sìkù tiyao on multiple SòngYuán Yì works).
Methodologically a strict Zhū-school orthodox compiler — narrower in source-discipline than even his father’s Tōng shì (which had drawn on 6 first-generation Zhū-disciples + 3 second-generation Cài-disciples). His exclusion of Yáng Wànlǐ (KR1a0040) from the Fùlù zuǎn shū’s sources — registered in the Sìkù tiyao — exemplifies the Wùyuán Hú-school’s jiǎngxué lineage-purity discipline. The work was the standard early-Yuán Zhū-school Yì-textbook through the Yuán-period 1313 examination-system canonization and into the Míng Yǒnglè era.
