The Lüshi Chunqiu (simplified Chinese: 吕氏春秋; traditional Chinese: 呂氏春秋; lit. 'Lü's Spring and Autumn'), abbreviated Lülan 吕览 "Lu Survey", also known in English as Master Lü's Spring and Autumn Annals, is an encyclopedic Chinese classic text compiled around 239 BC under the patronage of late pre-imperial Qin Chancellor Lü Buwei. In the evaluation of Michael Loewe, "The Lü shih ch'un ch'iu is unique among early works in that it is well organized and comprehensive, containing extensive passages on such subjects as music and agriculture, unknown elsewhere." One of the longest early texts, it extends to over 100,000 words.
Combining ideas from many different 'schools', it was traditionally classified as 'Syncretist', though there was no school that called itself Syncretist. Almost certainly written for review by Qin authorities, or those who were going to come into a position of authority, Yuri Pines considered it more moral leaning than the Strategies of the Warring States.
