What dynasty united the authoritive books of Confucianism in China?
Chinese classics Chinese classic texts or canonical texts () refers to the Chinese texts which originated before the imperial unification by the Qin dynasty in 221 BC, particularly the "Four Books and Five Classics" of the Neo-Confucian tradition, themselves a customary abridgment of the "Thirteen Classics". All of these pre-Qin texts were written in classical Chinese. All three canons are collectively known as the classics ( 經 ,  经 , "jīng",  "warp").
I Ching The I Ching ( in Mandarin), also known as Classic of Changes or Book of Changes, is an ancient Chinese divination text and the oldest of the Chinese classics. Possessing a history of more than two and a half millennia of commentary and interpretation, the "I Ching" is an influential text read throughout the world, providing inspiration to the worlds of religion, psychoanalysis, business, literature, and art. Originally a divination manual in the Western Zhou period (1000750), over the course of the Warring States period and early imperial period (500200) it was transformed into a cosmological text with a series of philosophical commentaries known as the "Ten Wings." After becoming part of the Five Classics in the 2nd century BC, the "I Ching" was the subject of scholarly commentary and the basis for divination practice for centuries across the Far East, and eventually took on an influential role in Western understanding of Eastern thought.
