Zhāng Chōng 章沖, Màoshēn 茂深, of the Southern Sòng. Grandson of the senior councillor Zhāng Dūn 章惇 (1035–1105) and son-in-law of the Chūnqiū specialist Yè Mèngdé 葉夢得 (1077–1148), through whom he came to his deep study of the Zuǒzhuàn 左傳. Knew Tāizhōu 台州 during the Chúnxī 淳熙 era; the Sìkù compilers infer his floruit from his self-preface to the Chūnqiū Zuǒshì zhuàn shìlèi shǐmò 春秋左傳事類始末 (KR2c0003), dated Chúnxī 12 (1185), only nine years after Yuán Shū’s Tōngjiàn jìshì běnmò of 1176. The work, which arranges the Zuǒzhuàn into self-contained topical narratives, is the earliest jìshì běnmò-format treatment of a Classic and the only surviving work attributed to him. CBDB carries him as personid 531176 with no recorded dates. No firm birth or death year has been established.
