Liú Xiàobiāo 劉孝標 (462–521), given name Liú Jùn 劉峻, zì Xiàobiāo (under which he is now universally known). Native of Píngyuán 平原 (modern Shāndōng). Captured as a child during the Northern-Wèi sack of Qīngzhōu 青州 in 469 and taken north, where he served briefly in the Wèi court and acquired his prodigious bibliographic learning before returning south in the 480s; thereafter he lived under the Qí and the Liáng, mostly in retirement on Mount Zǐyáng 紫陽山 in eastern Zhèjiāng, lecturing and writing. His scholarly output centres on the great commentary to the KR3l0002 Shìshuō xīnyǔ 世說新語 — a text-historical achievement of the first order, quoting some 400 source works, many of which now survive only in his citations — and on the essays Biànmìng lùn 辨命論 (Disputing Fate) and Guǎng jué jiāo lùn 廣絕交論 (Expanded Discourse on Severing Friendships), included in the Wénxuǎn 文選. He compiled the lost catalogues Lèiyuàn 類苑 and reorganized the Qí imperial library. CBDB records multiple persons under the name 劉峻 (ids 161107, 212211, 320231, 450750, 450751, 497254, 586711) without disambiguating lifedates; the present figure is securely identified by the Liáng shū 50 and Nán shǐ 49 biographies, which give the dates 462–521 followed here.
