One of the Zhōngxīng sìdà jiā 中興四大家 (“Four Masters of the Mid-Xīng-period,” with Lù Yóu 陸游, Yóu Mào 尤袤, Fàn Chéngdà 范成大), founder of the Chéngzhāi tǐ 誠齋體 of Sòng poetry.
Jìnshì of Shàoxīng 24 (1154) under Gāozōng. His career under Xiàozōng and Guāngzōng / Níngzōng included: provincial magistracies of Yǒngzhōu 永州 (under the patronage of Zhāng Jùn 張浚), Tàizǐ shìdú 太子侍讀 (Reader-in-Waiting to the Heir Apparent — the future Guāngzōng), Bǎomógé zhí xuéshì 寶謨閣直學士, governorship of Lìzhōu 利州, and Bǎomógé xuéshì 寶謨閣學士.
Refused all summonses by Hán Tuòzhòu 韓侂胄 in the Qìngyuán (1196) era; lived in retreat at Lúlíng. In Kāixǐ 2 (1206), on hearing of the launch of the disastrous Hán Tuòzhòu northern campaign that would lead to the Chīyáng defeat, “in indignation-and-grief refused food and died” (per Sòngshǐ).
Catalog-vs-external dating: the Kanripo catalog meta gives 1124–1206; CBDB id 10566 and the Sòngshǐ both give 1127–1206 (born Jiànyán 1, died Kāixǐ 2). The 1127–1206 dating is followed here as more authoritative.
Within the Kanripo corpus he is the author of KR1a0040 Chéngzhāi Yì zhuàn 誠齋易傳, completed by 1188. He is also the author of a vast body of poetry, prose, and political memorials collected in Chéngzhāi jí 誠齋集 (133 juan, in the Sìkù). The funerary inscriptions he composed for 張栻, Hú Quán 胡銓, and others are foundational documentary sources for the Southern-Sòng Dàoxué circle.
