Zhào Rǔténg, zì Màoshí 茂實, hào Yōngzhāi 庸齋, was a Sòng imperial-clansman — a seventh-generation descendant of Tàizōng — settled in Fúzhōu 福州 (Mǐn). Bǎoqìng 2 (1226) jìnshì; rose through the Hànlín drafting ranks to Duānmíngdiàn xuéshì 端明殿學士 (Editor of the Hall of Bright Vision), Concurrent Director of the Hall of the Spirit’s Aid, and Hànlín xuéshì chéngzhǐ 翰林學士承旨 (chief drafter of zhì-rank decrees). Trained in the Zhū Xī 朱熹 Daoxue tradition (Mǐn being its heartland), he openly confronted Shǐ Sōngzhī 史嵩之 and the Lǐ-zōng-era court favourites — his two memorials of Bǎoyòu 4 (1256) survive in his collection. CBDB (id 10948) gives no birth year, only the death year 1261 (Jǐngdìng 2). The Sìkù tíyào gives a balanced two-sided portrait: an upright remonstrator on one side, but on the other an embarrassed patron of Xú Lín 徐霖 (Jìngpō 徑坡) who, on Zhōu Mì’s 周密 testimony, called Xú “the Sìshuǐ of our day” (i.e. a new Confucius). His biography is in Sòng shǐ juan 413. Sole surviving work in the corpus: the six-juan Yōngzhāi jí 庸齋集 KR4d0346, reconstituted by the Sìkù editors from the Yǒnglè dàdiǎn.
