Zhouyi was written by Zhou Wenwang and Jichang. Is Duke of Zhou written by Ji Dan according to Zhouyi? Did Ji Dan write the Book of Changes?

According to legend, Zhou Wenwang's Zhouyi is based on Fuxi's Eight Diagrams, and Duke Zhou interpreted it according to the Eight Diagrams to some extent. Strictly speaking, Zhouyi really influenced the Duke of Zhou!

There are two versions of The Duke of Zhou, one is written by the Duke of Zhou according to legend, the other is a compilation written by modern people, and the latter is not from The Book of Changes!

Ji Dan (Duke of Zhou) ritual and music system, after the establishment of the ancient Zhou Dynasty, the most important thing was ritual, and divination was generally required (referring to the inscription of Zhou Dynasty, Oracle Bone Inscriptions divination was a customary ritual from Shang Dynasty to Zhou Dynasty), so Duke of Zhou did not write Zhouyi, but Zhou Wenwang's Zhouyi had a great influence on Duke of Zhou's ritual formulation!
