Dài Xǔ 戴栩, zì Wénzǐ 文子 (Zhū Yízūn’s Jīngyì kǎo citing Wáng Zàn gives the zì as Lìzǐ 立子; the matter is unsettled), of Yǒngjiā 永嘉 (Wēnzhōu, modern Zhèjiāng). Jìnshì of Jiādìng 1 (1208); served as Erudite of the Imperial Academy (太學博士), Imperial Secretariat-Drafter (秘書郎), Prefect of Línjiāngjūn (declined the appointment), and later Adjutant of the Húnán Pacification Commission. He was a direct disciple of Yè Shì 葉適 and the principal continuator of the Yǒngjiā 永嘉 prose-school after Yè’s death; his style accordingly mirrors that of the Shuǐxīn jí KR4d0294. As a poet he stood close to the Sìlíng 四靈 group of his fellow-townsmen Xú Zhào 徐照, Xú Jǐ 徐璣, Wēng Juǎn 翁卷, and Zhào Zǐzhī 趙紫芝, but cultivated a more “carved and chiselled” gōng 工 manner rather than the “pure and lean” qīngshòu 清瘦 of the Sìlíng proper. His self-styling Huànchuān 浣川 (“rinsing-rivulet”), reportedly chosen after retirement to pun on the older form Xiéchuān 斜川, gives the collection its title. The Sìkù editors record that during Shǐ Míyuǎn’s 史彌遠 ascendancy he successively flattered Shǐ in verse and lamented the demotion of Shǐ’s victim Hú Zhīróu 胡知柔, and so they treat his moral character with reserve while keeping his work for its literary value. His Jǐng 經*-shuō* (commentary on the Five Classics) is lost. His extant Huànchuān jí KR4d0319 is the Sìkù reconstitution from the Yǒnglè dàdiǎn.
