Eastern-Jìn military strongman, briefly self-proclaimed emperor of the short-lived Chǔ 楚 (403–404). Zì Jìngdào 敬道, xiǎo zì Língbǎo 靈寶. Son of the great Eastern-Jìn general Huán Wēn 桓溫 (312–373). In 403 he forced the abdication of Jìn Ān-dì 安帝 and founded his own dynasty; defeated and killed by 劉裕 Liú Yù (later founder of the Liú Sòng) within months. Despite his political record, Huán Xuán was a learned man with serious philosophical and Yì jīng interests. Surviving fragments of his Xìcí commentary are preserved in 陸德明 Lù Démíng’s Jīng diǎn shì wén 經典釋文 and were reconstructed by 馬國翰 Mǎ Guóhàn under the title Zhōu Yì xìcí Huán shì zhù 周易繫辭桓氏注 in Yùhán shānfáng jíyì shū 玉函山房輯佚書.
