Liushi zhenglun 劉氏政論 "Master Liu on politics" was a legalist treatise written during the very late Eastern Han period 後漢 (25-220 CE) by Liu Yi 劉廙 (180-121), courtesy name Gongsi 恭嗣, from Anzhong 安眾 in the commandery of Nanyang 南陽 (today's Zhenping 鎮平, Henan). He served the warlord Cao Cao 曹操 (155-220) as a clerk of the Counsellor-in-chief (chengxiang yuan 丞相掾). When Cao Pi 曹丕 assumed the title of Emperor of Wei (Wei Wendi 魏文帝, r. 220-226), Liu Yi was given the post of palace attendant (shizhong 侍中) and was invested as Marquis within the Passes (Guannei hou 關內侯).
His book had originally a length of 10 chapters, but only fragments of the chapter Zhidao 治道 "The way of governance" survive in Liu's official biography, quoted by Pei Songzhi 裴松之 (372-451). They are published in Ma Guohan's 馬國翰 (1794-1857) series Yuhan shanfang jiyi shu 玉函山房輯佚書.
