What did Zhou Yixue learn?

The most basic element of the Yi Gua system is the concept of Yin and Yang, including the nature and state of Yin and Yang. If we ignore the state of Yin and Yang and only talk about their nature, we can use Yang Yao (-) and Yin Yao (-) to represent Yin and Yang. The above-mentioned Yin and Yang hexagrams are overlapped three times from bottom to top, forming eight basic hexagrams, namely, "Gan, Kun, Zhen, Xun, Kan, Li, Gen and Hui", which are called Eight Classics hexagrams. You can get six hexagrams by overlapping eight classics and hexagrams. * * * * There are sixty-four hexagrams, which are called other sixty-four hexagrams, and each hexagram has a specific name. If we consider the state of Yin and Yang again, the concept of Yin and Yang can be further divided into four situations, namely "old Yin, Lao Yang, less Yin and less Yang", which can be expressed by four symbols, namely "X, O,-,-,-". Each order of each hexagram may have four states of Yin and Yang, so there are 4096 different hexagrams in all the hexagrams changing systems. If all the hexagrams with the same yin and yang properties are put together, 64 subsystems with the same name of the main hexagrams can be formed, which can be called a hexagram system. The content of the text description in the Book of Changes is the interpretation of the symbolic meaning of some Yi hexagrams in the sixty-four hexagrams system and the corresponding judgment of personnel quality (called occupation). Among them, the first item of each divination system is the corresponding static divination, and the last six items (there are seven items in Gankun divination system) are the sequential divination of the corresponding divination system. After Qin and Han dynasties, there was a wrong or vague understanding of it.

The books divination and Zhouyi originated from the practice of divination in Oracle Bone Inscriptions. Perhaps at the end of the Shang Dynasty, Zhou Wenwang wrote down the hexagrams in the sixty-four hexagrams system. Later in the Spring and Autumn Period, Confucius' disciples inherited Confucius' discovery of Zhouyi and wrote Yi Zhuan. When Qin Shihuang burned books to bury Confucianism, Lisi listed it as a medical divination book and preserved it.

The invention of using gossip to predict information in Zhouyi 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, Yi Gua and Zhouyi are a great information base.

After thousands of years of vicissitudes, Zhouyi has become the root of China culture. Yi Dao pays attention to the interaction between Yin and Yang, combines rigidity with softness, and advocates self-improvement and morality. In the 5,000-year history of civilization, the Chinese nation has been able to endure numerous disasters for a long time, tide over the difficulties, recover from the recession, and continue to grow and develop, which is closely related to our nation's grasp of the times of Yi Dao spirit.

The reason why Zhouyi, an ancient and splendid cultural treasure, can remain immortal lies in its practicality and scientificity. Its unique function of forecasting and reflecting in advance is unmatched by any scientific instrument at present, and it can measure people in the sky, the earth and the middle. The human body itself is an information sensor, which has the function of predicting information and has a fine and strict division of labor. In divination, the copper coin is placed flat on the palm of your hand, and the human easy field acts on the copper coin, making it move according to the induction easy field, so the change of the copper coin reflects the change of yin and yang of the corresponding thing.
