Lù Yóu 陸游 (1125–1210), zì Wùguān 務觀, hào Fàngwēng 放翁, of Shānyīn 山陰 (modern Shàoxīng 紹興, Zhèjiāng). Grandson of 陸佃 (the Wáng Ān-shí-school Zhōulǐ commentator) and son of Lù Zǎi 陸宰 (Northern-Sòng Hànlín scholar). One of the four great Southern Sòng poets — alongside 范成大, Yáng Wànlǐ 楊萬里, and Yóu Mào 尤袤 — and the most prolific: roughly nine thousand poems survive, the largest extant œuvre of any premodern Chinese poet. Lù Yóu first entered office through yìn (hereditary privilege) as Dēngshìláng; he was given jìnshì-equivalent qualification by imperial favour in Lóngxīng 1 (1163); he served in numerous prefectural posts, including Tōngpàn Kuízhōu from 1170 (the journey to which is recorded in his Rùshǔ jì KR2g0056 of 1170), and in Sìchuān military posts under Wáng Yán 王炎 (the experiences out of which his greatest patriotic poetry would emerge). He retired to his estate at Shānyīn in his late years and died there in early 1210 (lunar Jiādìng 嘉定 2, twelfth month / Gregorian January 1210). Posthumously titled Bǎomógé dàizhì 寳謨閣待詔. Lù Yóu’s prose works of significance include the Rùshǔ jì (the great upstream-Yangtze travel diary), his late-life Lǎoxuéān bǐjì 老學庵筆記 (KR3j0123) of miscellanies, and his NánTáng shū 南唐書 (KR2a0026). His patriotic themes — exile, the lost Northern territories, the unrealized hope of bēi fùZhōngyuán (avenge-and-recover the Central Plain) — set the dominant tone of late-Southern-Sòng cí and shī. CBDB id 3640 gives 1125–1209; standard Western convention (lunar / Gregorian conversion of his death in early 1210) gives 1125–1210; followed here.
