Southern Sòng 宋 Shàngshū commentator, native of Lúlíng 廬陵 in Jí’ān fǔ 吉安府 (modern Jiāngxī). Lifedates unrecorded; floruit defensibly mid-thirteenth century. CBDB lists two homonymous Sòng-dynasty figures (ids 43263 and 543606, the latter with index year 1217); neither has firm dates. Career was modest — he held only the local-academy post of Línjiāngjūn jūnxué jiàoshòu 臨江軍軍學教授, instructor at the prefectural military academy of Línjiāngjūn (also in Jiāngxī). His one surviving work is the Húshì Shàngshū xiángjiě 胡氏尚書詳解 (KR1b0024) in 13 juǎn, a teaching commentary on the Shàngshū circulated under three different titles: Shū jí jiě 書集解 (Jiāo Hóng’s Guó shǐ jīngjí zhì); Chū xué Shàngshū xiángjiě 初學尚書詳解 (“Detailed Exposition of the Documents for Beginners,” Zhū Yízūn’s Jīngyì kǎo — most likely the original title, registering the work’s pedagogical purpose); and the Sìkù-adopted Shàngshū xiángjiě. Methodologically he takes the Kǒng Ān’guó zhuàn as his baseline, supplements it with selections from Yáng Shí 楊時, 林之奇, 呂祖謙, and 夏僎 when the zhuàn is inadequate, and offers his own glosses for points all of these miss. He shows particular interest in concrete Shàngshū materials (the four star-position charts for the astronomical references in Yáo diǎn; a Tàijí tú 太極圖 inserted into his commentary on the Hóng fàn’s “初一曰五行”; recovered HànJìn glosses of variant graphs).
