What is a book?

The first book in the history of China was the Book of Changes, also called the Hutuluo Book of Luoshui. The Book of Changes is a mysterious work in ancient China. Because it was popular in the Zhou Dynasty, it was called the Book of Changes, and was regarded as the head of the Confucian classics. Judging from its arrangement style and text content, it is a book of divination. This paper discusses the extensive and profound Yijing, including Yijing and Yijing. In ancient books, only the names "Lianshan" and "Ghost Hide" are not discussed. When Qin Shihuang burned books to bury Confucianism, Li Si secretly included the Book of Changes in Medical divination, and survived. As for the author of the Book of Changes, Historical Records said that "the king of literature wrote the Book of Changes", so most of the ancients thought that the Book of Changes was written by Zhou Wenwang according to Sima Qian's theory, but today people have different views. Because it was written very early, the meaning of words evolved with the development of the times, and the content of the Book of Changes in the Spring and Autumn Period and the Warring States Period was not very good to read, so the ancients specially wrote the Book of Changes to interpret it. The "Book of Changes" we talk about today usually refers to the combination of the Book of Changes and the Book of Changes.
