Guō Sī 郭思 (1054–1132), zì Déyú 得閲 (also written 得裕 Déyù), of Héyáng 河陽 (Wènxiàn 溫縣, Hénán). Northern-Sòng official and literati editor.
Eldest son of Guō Xī 郭熙 (c. 1020–c. 1090), the great Northern-Sòng landscape painter; Guō Sī is the principal editor of his father’s posthumous painting treatise Línquán gāozhì 林泉高致, transmitted today as a foundational Chinese art-theory text. Sī’s own civil-official career: jìnshì of 元豐 5 (1082); rose through various central-court appointments to Huīyóugé zhíxuéshì 徽猷閣直學士 (Reader-in-Attendance of the Huīyóu Pavilion) and Tōngfèng dàfū 通奉大夫 (Grand Master for Thorough Service); retired with title intact.
In retirement he compiled the Qiānjīn bǎoyào 千金寶要 (KR3ed018) — an abridged practical reference drawn from Sūn Sīmiǎo’s Bèijí qiānjīn yàofāng — and first cut it as stone stelae at the Huázhōu 華州 prefectural office in 宣和 6 (1124). The stone-stelae publishing decision was deliberate: a public, durable medical resource for the impoverished and remote. CBDB id 14068 (1054–1132).
