Please briefly introduce what kind of book the Book of Changes is.

The Book of Changes, also known as the Book of Changes, is one of the oldest documents in China. It is said that it was written by Zhou Wenwang, and it was written in the Zhou Dynasty, so it is called Zhouyi. In fact, the Book of Changes is a knowledge that has been gradually developed and perfected in the history of China. English translation is the Book of Changes, which means a book that studies changes. In fact, this kind of translation can't explain the essence of Yijing (many Chinese have lost their original intention after being translated into English).

The Book of Changes is regarded as the first of the Five Classics by Confucianism. The Book of Changes describes the change of state with a set of symbol systems, and shows the philosophy and cosmology of China's classical culture. Its central idea is to describe the changes of everything in the world with the unity of opposites of Yin and Yang.

I ching in a broad sense includes I ching and I ching. The Book of Changes is divided into 30 hexagrams and Xia Jing into 34 hexagrams. Because the Book of Changes was written very early, around the Western Zhou Dynasty, the meaning of words evolved with the development of the times, and the content of the Book of Changes was not easy to read during the Spring and Autumn Period and the Warring States Period, so people in the Spring and Autumn Period and the Warring States Period wrote Ten Wings to interpret the Book of Changes.

It is generally believed that the Book of Changes was originally a book of divination, but its influence was biased towards China's philosophy, religion, medicine, astronomy, mathematics, physics, literature, music, art, military and martial arts. Since17th century, Yijing has also spread in the west.
