Who is the founder of the Book of Changes?

According to the three sages of Zhouyi, The Book of Changes and The Classic Biography of Zhouyi were co-authored by Fu, He (or Confucius).

Taking Fu's Book of Changes as evidence, his book Under Cohesion claims to be the king of the world, looks up to the family and spreads gossip. The preface to Historical Records Taishi Gong also said: Fuxi is honest and clean, and is good at gossiping. This point was clarified in Biography of the Yuezhe. Fuxi is the Eight Diagrams, and Zhou Wenwang rules the world for 3 14 hexagrams. "Zhou Benji" records: "Xibogai reigned for fifty years. Before and after he went to prison, he covered one gossip and sixty-four hexagrams. " "Confucius" carried out Confucius' sage and said, "Confucius is late, fond of easy things, arrogant, fond of divination and classical Chinese." Biography of Zhong Ni's Disciples further proves that Confucius' biography is easy to bend.

Mr. Gu Jiegang said: "The author didn't take the exam because of the official who was in charge of divination at that time." He also said, "The Ten Wings Theory of Philosophy can be regarded as philosophy, and the upper and lower classics are divinatory words occupied by Gui. Strictly speaking, folklore has been involved, not all philosophy, and certainly not literature and history. " The conclusion is that Zhouyi was not written by one person.
