Liú Kèzhuāng 劉克莊 (zì Qiánfū 潛夫, hào Hòucūn 後村, posthumous name Wéndìng 文定) was a native of Pútián 莆田 (modern Fújiàn) and is one of the towering literary figures of the late Sòng. Born into office through hereditary privilege (蔭), he rose to Edict Attendant of the Lóngtú Hall (龍圖閣直學士). He was the most important continuator of the Jiāngxī poetic school in the late Sòng, the principal critic-anthologist of his age, and the heir to Yáng Wànlǐ’s 楊萬里 manner. He studied under Zhēn Déxiù 真德秀 (Xīshān 西山), but the Sìkù editors note with disapproval his late-life accommodation of Jiǎ Sìdào 賈似道, citing the obsequious “congratulations on Chief Councillor Jiǎ” series in his collection. He was a close associate of 王邁 (Wáng Mài), 徐鹿卿 (Xú Lùqīng), and 包恢 (Bāo Huī). His prose, especially his colophons (tíbá 題跋), was widely admired. According to Wilkinson, Chinese History: A New Manual, Liú headed the Sòng Imperial Genealogy Office (玉牒所) and his collection preserves a draft Yùdié 玉牒 for the years 1218–1219, the only surviving fragment from that genre; Patricia Ebrey’s 2003 study reads the 43 epitaphs Liú wrote for women of his family. His principal works are the massive 196-juàn Hòucūn xiānshēng dàquánjí 後村先生大全集 (in SBCK; the WYG version of which is the 50-juàn Hòucūn jí KR4d0340) and the Hòucūn shīhuà 後村詩話 (separately catalogued in the Sìkù Shīwénpíng class).
