Wáng Tíngguī 王庭珪 (1080–1172), zì Mínzhān 民瞻, hào Lúxī xiānshēng 盧溪先生, native of Lúlíng 廬陵 (modern Jíān 吉安, Jiāngxī). One of the two great Lúlíng xiānshēng — paired with Liú Cáishào 劉才邵 劉才邵 of Shānxī. Jìnshì of Zhènghé 8 (1118); appointed Chálíngchéng 茶陵丞 but resigned for incompatibility with his superior; retired to Lúxī.
Wáng’s most famous act was the 1138 farewell-poem to Hú Quán 胡銓 胡銓 when the latter was banished to Lǐngnán for opposing the Shàoxīng peace: the line chīér bù liǎo gōngjiā shì; nánzǐ xū wéi tiānxià qí (the foolish-child accomplishes-not the public-affairs; the man-must do the empire-extraordinary [act]) — was so vehement that Wáng was himself banished to Lǐngnán in consequence. Under Xiàozōng he was recalled and granted Guózǐ jiān zhǔbù 國子監主簿; in Qiándào 6 (1170) further granted Zhí Fūwéngé. Died at age 93. CBDB id 12158 confirms 1080–1172. (Catalog meta has 1079–1171; CBDB is followed; both within the standard one-year boundary range.)
Author of substantial classical-philosophical works: Liùjīng Lúnyǔ jiǎngyì, Yì jiě, Yǔlù, the Cānghǎi yízhū 滄海遺珠, Fèngtíngshān cónglù 鳳停山叢錄 — most lost. Yáng Wànlǐ 楊萬里 was his pupil and praised his poetry as descended from Dù Fǔ and Hán Yù in xiónggāng húndà (vigorously-firm, deeply-broad) register. Liú Chéng 劉澄 said Wáng’s prose in Lúlíng could continue the Ōuyáng (= Ōuyáng Xiū) line.
His collection survives as Lúxī wénjí 盧溪文集 KR4d0176 in 50 juǎn — a substantial survival, with prefaces by Hú Quán et al. and appendices including Zhōu Bìdà 周必大’s zhìzhuàng and other postscripts.
