Liú Píng 劉玶 (1138–1185), youngest son of Liú Zǐhuī 劉子翬 劉子翬 of Chóngān 崇安 (Fújiàn). His father died in 1147, so Liú Píng was nine when his father died; the editing of his father’s literary collection (the Píngshān jí KR4d0177) was undertaken in adulthood, based on family papers. Zhū Xī 朱熹 — his father’s pupil and Liú Píng’s older friend — wrote the preface to the resulting collection.
CBDB id 11833 confirms 1138–1185.
