When did Zhouyi appear?

It should have started from the Shang Dynasty. Sima Qian said in Historical Records that "Wang Wen was arrested and played Zhouyi". In other words, Zhou Wenwang was held in a "ghost" by Shang Zhouwang for seven years. During this period, Zhou Wenwang deduced Fuxi and innate gossip, used yarrow, and after numerous calculations, he finally got the acquired gossip (including divination and rhetoric) and formed a text, which was the Book of Changes. In the process of studying the Book of Changes, later generations recorded their own experiences from the Book of Changes, and formed ten works, such as Jiezhang, Xiangyizhang, Xunyizhang, Shuogua, Xugua, Zagua and Classical Chinese, which were learned by later generations.
