Please tell the master of the Book of Changes briefly what the Book of Changes is about.

The birthplace of Zhouyi is Anyang, and now it is a world heritage city. Qili City is located at 10 km south of Anyang City.

Zhouyi is a classic box of Zhou Dynasty in China, and it is known as "the head of the group classics and the source of a hundred schools of thought". Western civilization has the Bible, and eastern civilization has the Zhouyi. Zhouyi culture is the root and source of China's cultural development, which has had a great and far-reaching impact on China's politics, economy, culture and many other aspects. China's architecture, medicine, music, painting and daily life are inextricably linked with Zhouyi, which still affects the national character and spirit of China people. Confucius read the Book of Changes and Wei compiled three wonderful books. Even the Analects of Confucius quoted many words from the Book of Changes.

Zhouyi is an ancient classic, and it is a knowledge about human thoughts and the essential laws of the universe. If its principle is correctly understood, it will have a great impact on the development of the future world.

Zhou Wen Wang Jichang, the author of Zhouyi, was a Xibo nationality in Shang and Zhou Dynasties, and was founded under Qishan. He accumulated virtue and did good deeds and became a great politician. He was imprisoned in Youli (now Tangyin North, Anyang City) for worshipping Houhu and slandering Zhou Wang, and was later released. Benefiting from benevolent government, most governors in the world are obedient. After Zhou Wuwang won the world, he was honored as the leader of the princes in the last years of Shang Dynasty, known as the Hou of Northwest China in history, and was named as. Our ancestors, Gu Gong and his son, followed the cause of Hou Ji and Gong Liu, adopted the calendar and advocated the social atmosphere of respecting the elderly, showing little kindness and respecting the virtuous, so as to develop the social economy of their territory. Together with his son Ji Fa, he hired Jiang Shang as a strategist in Diaoyutai, Panxi, Baoji, and led an army to attack the Shang Dynasty from Qishan. He was a pioneer of the Western Zhou Dynasty. Invented the king of Wen gossip, spread all over the world. According to historical records, "Wen Wang was imprisoned and played Zhouyi". During his imprisonment by Shang Wang, he wrote Zhouyi in prison and reigned for 50 years.

Historical Records records that "the king of letters traveled in Zhouyi", so the ancients mostly agreed that Zhouyi was written with Sima Qian's theory, but today people have different views. Because it was written very early, with the evolution of the times, the meaning of words was not understood by the world, and the content of Yi was not very good to read in the Spring and Autumn Period and the Warring States Period. Therefore, the ancients 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.

The Book of Changes 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. It is also called the Book of Changes for short, including classics and biographies. The Book of Changes is a divination book, the main body of which is the interpretation of the symbolic meaning of the corresponding Yi hexagrams and the judgment of the good and bad of personnel, while the biography part is the understanding of Yi and the development of the Zhouyi characters.

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. Overlapping the Eight Classics with the hexagrams, you can get six hexagrams, a total of sixty-four hexagrams, which are called sixty-four other 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.

According to ancient books, there are three changes: Lianshan, Guizang and Zhouyi. During the Spring and Autumn Period, Zhouyi became popular as a divination book, and people kept explaining and studying it, including Confucius. In the Warring States period, there were seven kinds of Yi Zhuan, including Classical Chinese, Zhuan Zhuan, Xiang Zhuan, Ci Zhuan, Zhuan Xu and Za Zhuan. Later, the Book of Changes merged into the Book of Changes and became the Book of Changes we see today.

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.

At present, there is still no significant progress in the exploration of the principle of Yi-ology in China, and the theoretical research is stagnant, and the thinking is chaotic, and the practical application tends to be mysterious. The above situation has seriously distorted the academic status of Yi-ology, hindered the benign development of China Yi-ology, and blinded the true value of Yi-ology.
