What is the attitude of the pre-Qin philosophers towards the Book of Changes?

Zhouyi is the origin of China's philosophy, and hundreds of theories such as Confucianism, Taoism and law in the Spring and Autumn Period all originated from Zhouyi. Therefore, Zhouyi is also called the head of the group classics. The philosophy of Zhouyi is that the ancients abstracted some basic laws according to their own understanding of the universe, and then tried to guide people's life behavior with these laws. It is what Laozi said, "Man teaches Heaven, Heaven teaches Taoism, and Taoism is natural." The "heaven" here should not refer to "the nature of heaven and earth", but to "the father of the son of heaven" (otherwise, there is something wrong with the logic of Laozi's words, so how can the Tao naturally take the law). "Heaven" should be a "perfect man" in ancient people's thinking, and his son Tianzi managed the people on his behalf. People's behavior should take "Heaven" as an example, and the behavior of "Heaven" is based on "Tao", which is the law of natural development and change, so it is said that "Tao is natural".
