Without haste, there is no explanation: it arrived at a high speed without seeing it leave in a hurry, but it arrived without seeing its action. The relevant contents are as follows:

This word comes from the Book of Changes, and the original text says: "God is unique and cannot be an unexpected guest."

The Book of Changes, including the Book of Changes and the Book of Changes, is one of the "three changes" (another view: the Book of Changes is three changes, not the Book of Changes) and is one of the traditional classics. The Book of Changes recorded in Hanshu is "the people are more sacred and the history is three ancient".

According to legend, Fuxi in ancient times left the image of heaven and earth; The way Zhou Wenwang played the Book of Changes in the Middle Ages; In modern times, Confucius and his disciples studied it and later annotated the Book of Changes, which became the Book of Changes. The combination of classics and biographies eventually became Zhouyi. ?

Classics are mainly composed of 64 hexagrams and 384 hexagrams, each of which has its own interpretation. Biography, as a divination book, contains seven kinds of words to explain divination, which are collectively called Ten Wings, and it is said that it was written by Confucius.

During the Spring and Autumn Period, official schools began to evolve into private schools. There is a gradual development before and after the Yi-ology, and a hundred schools of thought contend, so it is easy to divide. Since Confucius praised the Book of Changes, the Book of Changes has been regarded as a Confucian classic and the first of the Six Classics by Confucianism.

Outside of Confucianism, there are two parallel schools of Yi-ology and Confucian Yi-ology: one is Yi-ology, which still exists in the old forces; The other is Laozi's Taoist Yi, which began to be divided into three branches. ?

The General Catalogue of Sikuquanshu divides the origin and evolution of Yi-ology into "two schools and six schools". Two schools, namely, the school of mathematics and the school of righteousness; Six cases, one is divination, the other is auspiciousness, the third is accident, the fourth is old Zhuang Zong, the fifth is Confucianism, and the sixth is history.

Zhouyi is the theoretical source of natural philosophy and humanistic practice in China's traditional ideology and culture, the crystallization of China's ancient thoughts and wisdom, and is known as the "source of Tao". The content is extremely rich, which has had a far-reaching impact on China's politics, economy, culture and other fields for thousands of years.
