Liú Yīngkuí 劉應奎 (active early Yuán, Dàdé 大德 era 1297–1307), exact dates uncertain, was the younger brother of the Sòng loyalist Liú Fú 劉黻 (see 劉黻). Born at Lèqīng 樂清 in Wēnzhōu (modern Zhèjiāng) to the same family as his elder brother, he lived through the SòngYuán transition and survived into the early Yuán. He is known chiefly as the editor and preserver of his elder brother’s fragmentary surviving works: after the fall of the Sòng and the loss of the principal Liú Fú archive (carried with the imperial flight by sea and dispersed), Yīngkuí spent his middle years gathering “broken slips and torn pages” — together with poems and prose remembered by his brother’s friends — and ultimately printed them as the Méngchuān yígǎo 蒙川遺稿 in four juàn (KR4d0355) during the early Yuán Dàdé era. His preface to that work, dated the shàngyuán 上元 day of the year jǐyǒu 己酉 (perhaps Dàdé 13, 1309, though the dating is ambiguous), is the principal documentary source for the transmission history of his elder brother’s writings.
He was also the patron who solicited Zhèng Chúsūn 鄭滁孫’s Cháoyánggé jì 朝陽閣記 — preserved with the Méngchuān yígǎo and the principal biographical record of Liú Fú’s final years. The two brothers are mentioned together in the Fújiàn tōngzhì 福建通志 (which, however, garbles Liú Yīngkuí’s name in some recensions). Liú Yīngkuí appears not to have served under the Yuán.
