I believe that anyone who has studied "The Book of Changes" basically knows that there is a saying that this book pays attention to the laws of heaven and earth. There is another theory that is accepted by more people, that "The Book of Changes" is a book of divination and prediction. But the most comprehensive description is: "The Book of Changes" records all the laws of nature in the form of sixty-four hexagrams. These laws in nature are eternal, so people can perform divination according to the development of things, and use those laws to , to deduce the development of things, which is what we call prediction.

"The Book of Changes" is called the source of the great road because it talks about "the way of heaven", "the way of earth" and "the way of humanity". There is a famous saying that I believe everyone has heard: "Heaven moves vigorously, a gentleman strives to constantly strive for self-improvement, the terrain is good, and a gentleman is virtuous." This sentence means that when people live in the world, they must be as broad as the heaven and the earth, and have a great mind. , this is a true gentleman. The book also uses sixty-four hexagrams to tell various things about people in heaven and earth.

He explains ethics, morals and ways of doing things to people, and talks about the heaven, earth, sun and moon. Yin and Yang also show that everything is divided into Yin and Yang, just like people are divided into good and bad people. Therefore, the first lesson in the book talks about how people should use the virtues of heaven and earth to restrain their bad side, and teaches us to learn from all things in heaven and earth. When looking at the "Book of Changes", we must first know that the "Book of Changes" is not the same as the "Book of Changes". It was written by the sages of our country to explore the source of the world. I believe everyone has heard of the myth of "Pangu created the world". This mythical story comes from the "Book of Changes".

Based on this myth, people in ancient times believed that at the beginning of the creation of the world, the universe was dead and dark. At that time, there was no distinction between heaven and earth, day and night, and the world at this time was called chaos. "Book of Changes" calls this situation Tai Chi, and before the heaven and earth are formed, it is Wuji. As the ancients continued to explore, they gained their own experiences by observing the laws of nature. Later, these experiences were directly evolved into the prototype of "The Book of Changes".
