Liú Xuéjī 劉學箕 (fl. ca. 1190–1230), zì Xízhī 習之, hào Zhǒngchūnzǐ 種春子 / Fāngshìxián jūshì 方是閒居士, was a Southern Sòng yǐnshì (recluse-scholar) of Chóngān 崇安 (Fújiàn). He was the great-grandson of Liú Gé 劉韐 (the Jìngkāng-era martyr-official), the grandson of Liú Zǐhuī 劉子翬 (Zhū Xī’s teacher and a figure in the Mínxué lineage), and the son of Liú Píng 劉㻫. He never held office, settling in his late forties at Nánshān below his ancestral hill, building a Fāngshìxián hall by a lotus pond. His extant collection, Fāngshìxián jūshì xiǎogǎo 方是閒居士小稿 KR4d0317 in 2 juǎn, is prefaced by Liú Huái 劉淮 (溪翁), Zhào Fān 趙蕃 (Dōnglǐ), and Zhào Bìyuàn 趙必愿 (Kāifēng) — all dated to Jiādìng 10 (1217). His cí — particularly the Jīnlǚqū setting his shùhuái to Xīn Qìjí’s 辛棄疾 rhyme — is regarded by the Sìkù editors as nearly indistinguishable from Xīn Qìjí’s own. CBDB index year 1168.
