The Book of Changes is a philosophical work in ancient China, also known as the Book of Changes. It is said that it was written by Zhou people because it is profound in thought, comprehensive in content and smooth in meaning. Based on the dualism of yin and yang, it is a book that demonstrates and describes the law of things. It classifies the characters of all things in the world and heavenly stems and earthly branches's Five Elements Theory, even accurate enough to make a more accurate prediction of the future development of things. Zhouyi is the root of natural philosophy and ethical practice in China's traditional ideology and culture, which has a great influence on China culture. It is the crystallization of China's 5,000-year-old wisdom culture and is known as "the head of the group classics and the source of the avenue". In ancient times, it was the study of emperors and a compulsory skill for politicians, strategists and businessmen.
