What are the contents of Zhouyi?

Zhouyi is one of the oldest, most authoritative and famous Confucian classics in China, and it is the crystallization of the wisdom of the Chinese nation. . The Book of Changes, also known as the Book of Changes, consists of two parts: classics and biographies. Its basic factors are Yang (-) and Yin (), which are superimposed to form eight diagrams, namely, dry, Kun, earthquake, root, separation, hurdle, intercourse and intercourse. Eight trigrams overlap again to form sixty-four hexagrams, such as Tai and Wu, and each hexagram has six hexagrams. Classics include four parts: divinatory symbols, divinatory symbols, divinatory symbols and divinatory symbols. Gua Ci is to explain the meaning of all hexagrams, and Yi Ci is to explain the meaning of each hexagram. The Book of Changes is divided into two parts, one is from dryness to detachment, and the other is thirty hexagrams. There are thirty-four hexagrams from the salty classics to the poor classics. This is how Xiping Shijing is divided, and it has not changed since the Han Dynasty. The origin of Zhouyi is Hetu and Luoshu. Legend has it that in ancient times, there appeared a dragon horse with characters on its back in the Yellow River, and a tortoise with characters on its back in Luoshui, and saints made gossip accordingly. At the end of Shang Dynasty, Zhou Wenwang wrote sixty-four hexagrams, and later in the Spring and Autumn Period, the sage Confucius wrote Yi Zhuan. "Zhou" in Zhouyi refers to the Zhou Dynasty, and "Yi" means change. According to ancient books, there are "three changes", namely, linking mountains, returning to Tibet and Zhouyi. During the Spring and Autumn Period, Zhouyi became popular as a divination book, and it was constantly explained and studied by people, including Confucius. By the Warring States period, there were seven kinds of ten Yi Zhuan, which were called "Ten Wings". Later, the Book of Changes merged into the Book of Changes and became the Book of Changes we see today. The book Zhouyi is about reason, image, number and industry. In form and method, it seems to be a book devoted to Yin and Yang gossip. But in fact, the core problem it discusses is to reveal the natural law of the development and change of things in the universe and the law of unity of opposites, and to use this world outlook and gossip to predict all kinds of information of nature, society and people themselves. The Book of Changes is very rich in content and covers a wide range. This paper discusses astronomy first, geography second, personnel centered, from natural science to social science, from social production to social life, from how emperors and generals govern the country to how ordinary people behave, and so on. It is all-encompassing and ubiquitous. Zhouyi is the origin and foundation of China's prediction and information science. The eight diagrams and sixty-four hexagrams in Zhouyi not only systematically record the hidden, past, present and future information reflected by natural science, social science, humanities and medicine, but also have valuable methods to predict information. In Zhouyi, the invention of the method of predicting information by gossip is a true portrayal of China people's materialistic world outlook. The difficulties they encounter in practice and daily life are not to turn to idols, but to use scientific methods to predict the good and bad of nature and personnel through gossip, so as to be aware of everything and be prepared for everything, so as to better understand, transform and promote the continuous development of society. Therefore, the sixty-four hexagrams in Zhouyi is a great information base. Zhouyi is a book that infers things from the randomness of yin and yang and numbers. Most people don't understand, but there is no need to delve into it. Yes (recommended by the teacher), but I still can't understand it after reading it twice. I simply don't know what to say. Strictly speaking, Zhouyi is a philosophical work of subjective materialism that integrates astronomy, mathematics, the art of war, the strategy of governing the country, life, moral cultivation and the development and change of things. It is a good book to train people's thinking. Many Nobel Prize winners have succeeded. I think Mark Enks read it before he studied Marxist philosophy. Therefore, Marxist philosophy only highly summarizes the contents of Zhouyi. Ancient science was very backward, and many natural phenomena could not be analyzed, so the theory. Simply put, 1. Yi turned out to be a fortune teller. 2. But when it comes to the Book of Changes, Confucius basically interprets the Book of Changes from a philosophical perspective. Although this explanation can also be applied to divination, Zhouyi is listed as a classic because it contains comprehensive philosophical thoughts. 3. The Book of Changes can't be used as a book of divination, because Confucius only understands the Book of Changes from a philosophical point of view, and there is basically no discussion about divination. Divination in later generations is the most important. Basically, it has nothing to do with Zhouyi. 4. Philosophy can be applied to anyone, but taking Zhouyi as a career will have no practical significance. 5. The reason why fortune tellers still list Zhouyi as a profession is because Zhouyi has not abandoned the basic principles of Zhouyi, and other Zhouyi have been lost.
