Zhù Yáo 祝堯 (fl. early 14th c.), zì Jūnzé 君澤. Native of Shàngráo 上饒 (Xìnzhōu, modern Jiāngxī). Jìnshì of Yányòu 5 (1318), the second Yuán-state examination. Held office as Magistrate (yǐn) of Jiāngshān 江山-county, later Vice Prefect (tóngzhī) of Wúxīzhōu 無錫州 (per the Jiāngxī tōngzhì) or of Píngxiāngzhōu 萍鄉州 (per the Guǎngxìn fǔzhì) — the two gazetteers disagree.
Compiler of the 古賦辨體 Gǔfù biàntǐ KR4h0077 in 8 juǎn with a 2-juǎn outer collection — the principal Yuán-period theoretical treatise on the fù genre, organising representative fù from the Chǔcí through the Sòng with historical-stylistic analysis. Zhù’s central theoretical contribution: identifying the wèndá-format fù (problem-and-answer, originating in Bǔjū / Yúfù) as the structural prototype of Sīmǎ Xiàngrú’s Zǐxū / Shànglín — with the outer frame as prose, the middle filling as fù; the genre’s two later divergences — qíLiángTángchū páitǐ (parallel-prose-style) and Tángmò Sòng wéntǐ (Late-Táng-and-Sòng prose-style) — preserved respectively the rhetorical and discursive poles of the original. He Zhuó 何焯’s Yìmén dúshū jì (Qīng) critiques Zhù for over-distinguishing fù and sòng in his commentary on Pān Yuè’s Jítián fù; the Sìkù editors defend Zhù.
