The Lüshi Chunqiu, 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 Qin state Chancellor Lü Buwei, some years before the unification of China as the Qin dynasty. In the evaluation of Michael Carson and 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, which are unknown elsewhere. It is also one of the longest of the early texts, extending to something over 100,000 words."

The Chinese classics or canonical texts are the works of Chinese literature authored prior to the establishment of the imperial Qin dynasty in 221 BC. Prominent examples include the Four Books and Five Classics in the Neo-Confucian tradition, themselves an abridgment of the Thirteen Classics. The Chinese classics used a form of written Chinese consciously imitated by later authors, now known as Classical Chinese. A common Chinese word for "classic" literally means 'warp thread', in reference to the techniques by which works of this period were bound into volumes.
