Late-Sòng / Yuán-period 宋元 classical scholar and historian, native of Lánxī 蘭溪 in Wùzhōu 婺州 (modern Zhèjiāng). Zì Jífǔ 吉父; hào Rénshān 仁山; posthumously canonized (Yuán) Wén’ān 文安. Lifedates 1232–1303 are firm (CBDB id 10731). Studied under 王柏 (Wáng Bǎi, Lǔzhāi 魯齋, 1197–1274), the leading disciple of Hé Jī 何基, who had himself studied under Huáng Gàn 黃榦 (Zhū Xī’s son-in-law and chosen successor); the Hé–Wáng–Jīn line, joined later by Xǔ Qiān 許謙 (1269–1337), is the so-called BěiShān sì xiānsheng 北山四先生 — the four chief masters of the late-Sòng / Yuán Wùzhōu ZhūXī orthodoxy.
In Déyòu 1 / 1275 (the year before the Sòng court fled south to Lín’ān’s collapse) he was summoned by the throne to serve as Shǐguǎn biānxiū 史館編修 (“Compiler of the Historiography Institute”) and declined. After the Yuán conquest (1279) he refused all official invitations and lived the remainder of his life as a recluse and teacher in his native Wùzhōu, dying in Dàdé 7 / 1303. Biography in Yuánshǐ 元史 Rúxué zhuàn 儒學傳, with funerary xíngzhuàng 行狀 by his student Liǔ Guàn 柳貫 (1270–1342).
Major works: (1) the early Shàngshū zhù 尚書注 / Shàngshū zhāng shì jù jiě 尚書章釋句解 in 12 juǎn (composed in his youth — Liǔ Guàn’s xíngzhuàng says “the Zhāng shì jù jiě he composed in his early years was already a complete book”; recorded as still extant by Zhū Yízūn but not seen by the Sìkù compilers and now lost); (2) the late-life Shàngshū biǎozhù 尚書表注 (KR1b0025) in 2 juǎn, his definitive Shàngshū work, distinguished by an unusual page-marginal annotation format with four-direction marginalia rather than running commentary — published in the Tōngzhìtáng jīngjiě 通志堂經解 and in the Sìkù; (3) the Tōngjiàn qián biān 通鑑前編 — a chronological history of pre-Zhōu antiquity continuing Sīmǎ Guāng’s 司馬光 Zīzhì tōngjiàn 資治通鑑 backward to Yáo, taking 胡宏 (Hú Hóng, 1106–1161)‘s Huáng wáng dà jì 皇王大紀 as a starting point and supplemented with extensive Shàngshū-anchored chronological argument (separately in the Sìkù); (4) the Lúnyǔ Mèngzǐ jí zhù kǎozhèng 論語孟子集注考證, a sub-commentary on Zhū Xī’s Sì shū jízhū; and (5) considerable poetry and miscellany (Rénshān wénjí 仁山文集). Within the Shàngshū tradition, the Biǎozhù is one of the four major Sòng Shū commentaries cited by the Sìkù compilers as supplementing or correcting Cài Shěn’s Shū jízhuàn (alongside Huáng Jǐngchāng’s Zhèng wù biàn yí, Chén Lì’s Shū zhuàn zhézhōng, and Dǒng Dǐng’s Shū zhuàn zuǎnshū).
