When was the Book of Changes born?

Generally speaking, the Book of Changes was created by Fuxi, one of the Three Emperors and Five Emperors. According to historical research, Fuxi lived between 3000 and 5000 BC. Two thousand years later, at the end of Shang Dynasty, Jichang, one of the "Nine Marquis" in Zhou Wang, invented or perfected sixty-four hexagrams and wrote them. Ji Chang was able to create sixty-four hexagrams because he was imprisoned in the imperial prison in Iraq (yǒu) (now Tangyin, Henan), and because he really had nothing to do, he pondered in his mind every day and superimposed the eight diagrams into sixty-four hexagrams. So Sima Qian said in Historical Records that "Xibo was arrested? In the Book of Changes, he also said that Xibo "benefited from the fact that the Eight Diagrams in the Book of Changes are sixty-four hexagrams. "
