Why can the ancients thousands of years ago write some wonderful books like the Book of Changes, but it is difficult for more intelligent modern people to understand them?

Zhouyi is an ancient book with profound connotation, wide influence and long history in the history of China civilization. It is known as "the head of the group classics" and "the source of the avenue". For thousands of years, Zhouyi has attracted researchers from all fields to analyze and apply it with its peculiar structural form, abstract symbol display, eternal meaning and complex and magical mechanism, forming a huge research system of Yi-ology. Some people think that it is a philosophical classic that can defend the country and cultivate one's morality, while others think that it is a book of divination, which is difficult to be elegant.

The Book of Changes, including Lianshan Yi, Guizang Yi and Zhouyi, is one of the Book of Changes. Because Lianshan and Guizang have been lost for a long time, there is only one Book of Changes handed down from generation to generation, so the Book of Changes now refers to the Book of Changes in general.

Zhouyi is essentially a book about change, and a philosophical work that guides people to apply the laws of nature and social development. It was formed by the ancient sages of China through long-term observation of natural and social phenomena. It highly summarizes various social practice activities and their results, and reflects the phenomena and development laws of all things in the universe. The Book of Changes is all-encompassing, extensive and profound, and it is the theoretical source of natural philosophy and humanistic practice in China traditional culture. Its content involves philosophy, politics, life, literature, art, science and many other fields. It is the crystallization of China's ancient thoughts and wisdom, and is known as "the source of the road".

The Book of Changes is extremely rich in content, which has had a far-reaching impact on China's politics, economy, culture and other fields for thousands of years. Therefore, it is considered to be the first of the group classics and a classic of Confucianism and Taoism. In ancient China, "divination" prevailed, which was to predict the future development of events. The Book of Changes is just a book that summarizes the laws and theories of these predictions. Therefore, the Book of Changes is also regarded as a book of divination, but we think it is necessary to regard the Book of Changes as a study of divination.
