Lú Zhàolín 盧照鄰 (ca. 634–686)
Zì Shēngzhī 昇之, hào Yōuyōu zǐ 幽憂子 (“Master of Deep Sorrow”). Native of Yōuzhōu 幽州 Fànyáng 范陽 (modern Zhuōzhōu 涿州, Héběi), of the powerful Fànyáng Lú lineage. Third of the Sì jié 四傑 (“Four Outstanding Ones”) of early-Táng letters, alongside Wáng Bó 王勃, Yáng Jiǒng 楊炯, and Luò Bīnwáng 駱賓王.
Began his career as diǎnqiān 典簽 to the Liáng prince Lǐ Yuányù 李元裕 — a junior staff post that gave him access to the prince’s library, where he is said to have read the entire collection. After Lǐ Yuányù’s death he served briefly as xīndū wèi 新都尉 in modern Sìchuān before contracting an incurable autoimmune disease (described in the sources as fēngbì 風痺 — the contemporary diagnostic term for what modern medicine retrospectively identifies as either rheumatoid arthritis or polymyositis) which progressively crippled his hands and feet. His last decade was spent between Chángān and Tàibáishān 太白山, where he sought alchemical cures and is reported to have consulted Sūn Sīmiǎo 孫思邈; he eventually retired to Yángzhái 陽翟 county and built himself a tomb mound on the bank of the Yǐngshuǐ 潁水, into which he drowned himself in ca. 686 after writing the Wǔ bēi wén 五悲文 and Shì jí wén 釋疾文 (“Letter of Reconciliation with Illness”) that close the autobiographical portion of his collected works.
His extant collection is the Lú Shēngzhī jí / Yōuyōu zǐ jí KR4c0005 in 7 juǎn, recompiled by Zhāng Xiè 張燮 in the late Míng. CBDB gives 634–686 (cbdbId 33651); the catalog meta’s ca. 641 – ca. 680 is the older Wén Yīduō 聞一多 estimate, now displaced by the modern scholarly bracket; both ranges are still found in Chinese reference works.
