Liú Xīzhòng 劉羲仲 (fl. late 11th c.), zì Zhuàngyú 壯輿. Native of Yúnzhōu 筠州 (modern Gāo’ān, Jiāngxī). Eldest son of 劉恕 (Liú Shù, 1032–1078), one of the three principal compilers of KR2j0001 Zīzhì tōngjiàn 資治通鑑 under Sīmǎ Guāng; younger brother of the calendrical scholar Liú Xīsǒu 劉羲叟. (The form 義仲, found in transmitted texts of the Sòngshǐ and Zhōu Mì’s 癸辛雜識, was identified by the Sìkù editors as a transmissional error and emended to 羲仲, the form preserved in the work itself.)
Liú Xīzhòng never sat for the jìnshì. His one recorded substantive appointment is the honorific Jiāoshè zhāiláng 郊社齋郎 (Resident at the Suburban Sacrifices Hall) awarded to him after the Zīzhì tōngjiàn’s presentation in Yuánfēng 7 (1084), in posthumous recognition of his father’s compilation labour — a benefice reserved for the descendants of meritorious officials. He was active in the Yuányòu and early Shàoshèng periods.
His one significant work is the KR2o0006 Tōngjiàn wènyí 通鑑問疑 in 1 juàn — a compilation of his late father’s recorded historiographical disputes with Sīmǎ Guāng over Tōngjiàn editorial decisions, supplemented by Liú Xīzhòng’s own eight queries to 范祖禹 (Fàn Zǔyǔ) and Fàn’s responses. The work is one of the principal first-hand testimonies to the Tōngjiàn’s internal editorial disputes — most importantly Liú Shù’s lost argument for treating ShǔHàn as legitimate succession, a position Zhū Xī revived in KR2o0020 Tōngjiàn gāngmù.
