Hè Xún 賀循 (260–319), zì Yànxiān 彥先, native of Kuàijī Shānyīn 會稽山陰 (modern Shàoxīng, Zhèjiāng). His standard biography is in Jìn shū 68 (列傳 38). A leading southern-school classicist and ritualist, he was the principal advisor on ritual matters to the founding Eastern-Jìn emperor Sīmǎ Ruì (Yuándì) and the architect of much of the early Eastern-Jìn court-ritual programme. He held the offices of Tài-cháng 太常 (chief of the ancestral-temple office) and Tài-zǐ shǎo-fù 太子少傅 (junior preceptor to the heir-apparent).
His ritual scholarship is the most substantial of the Eastern-Jìn court period: a Sāngfú jì 喪服記 (preserved in CHANT as KR1d0117 Hè-shì sāng-fú pǔ), a Sāngfú yào jì 喪服要記 (KR1d0118 Hè-shì sāng-fú yào jì), and numerous biàn-lǐ judgements preserved in Tōngdiǎn. His prestige as Tài-cháng is the subject of frequent court-memorial appeals: he is the named recipient of the Shàngshū fú 尚書符 ritual queries cited in KR1d0097 Xiōnglǐ (on shrine-tablet storage), and his rulings are cited as authoritative by Yú Xǐ in KR1d0095 Guǎnglín and by Hé Chéngtiān in KR1d0101 Lǐlùn.
His dates 260–319 are settled in the Jìn shū. No CBDB id assigned in current dump.
