Now Zhouyi is often associated with fortune telling. What was the original purpose of Zhouyi?

Yijing, one of the three changes of Yijing (another view: Yijing is three changes, not Yijing), is one of the traditional classics. It is said that it was written by Zhou Wenwang Ji Chang, including the Book of Changes and the Book of Changes? . Classics are mainly composed of 64 hexagrams and 384 hexagrams, each of which has its own interpretation (hexagrams) for divination. The Book of Changes did not put forward the concepts of Yin-Yang and Taiji, but was influenced by Taoism and Yin-Yang theory. Biography contains seven kinds of words to explain hexagrams, a total of ten articles, collectively known as "Ten Wings", which is said to be 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. In addition to Confucianism, there are two schools of Yi-ology and Confucianism-Yi-Yi, which develop in parallel: 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 accidents, 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. Most scholars believe that Yi Zhuan was written in the Warring States Period. From Ouyang Xiu's Yi Tong Wen Zi to Su Shi, few people believe that Confucius did it for hundreds of years.
