Duàn Kèjǐ 段克己 (1194–1252), zì Fùzhī 復之, sobriquet Dùnān 遯菴 (“Hide-Away Hermitage”). Native of Jìshān 稷山 (Hédōng, modern Shānxī). Elder brother of 段成己. The two brothers were praised in their youth by the Jīn Shàngshū Zhào Bǐngwén (趙秉文) as the “Two Marvels” (Èrmiào 二妙) — whence the title of their joint collection Èrmiào jí 二妙集 KR4h0071. Kèjǐ never took the jìnshì in the Jīn (because of juébǔ 缺補 administrative gaps), and after the Jīn fall in 1234 he refused all Yuán-state appointment, living out his days as a yímín in the Héfēn region with his younger brother. His poetry was marked by bone-firm-and-cold air, austere and chilled feeling — the Sìkù editors note his “gǔlì jiānjìn, yìzhì cāngliáng” (firm and rigorous bone-power; bleak-and-cold sentiment). With his brother Chéngjǐ he is the principal subject of KR4h0073 HéFēn zhūlǎo shījí (compiled by Fáng Qí). CBDB person 34964. Yuánshǐ Yǐnyì zhuàn.
