What are the two major schools of Yi-ology in ancient China?

In ancient China, there were two main schools of Yi-ology: Yi-ology and Yi-ology.

The Book of Changes quotes the research results of human beings on the divination book The Book of Changes. Since the Han Dynasty, there have been a number of Confucian classics scholars who specialize in the Book of Changes. Although their research directions are different, their research objects are the same, so the Book of Changes has gradually formed.

The characteristics of image number and righteousness in Zhouyi have profound connotations. When studying Zhouyi, Yi scholars have different opinions and formed various viewpoints and schools, among which the most influential ones are image number Yi and righteousness Yi.

Yi-ology belongs to the broad category of Confucian classics. Its purpose is to explore and expand the moral significance, values and philosophical thoughts contained in the names, words and images of hexagrams in the Book of Changes, so it belongs to many academic factions. Wang Bi in Wei and Jin Dynasties and Cheng Yi in Song Dynasty are the main representatives of Yi-ology.

The Yi-ology of Image Numbers pays more attention to the study of divination and divination in the Book of Changes, and infers the good or bad of personnel through the truth learned, so it is more used for calculation and divination. Yi-ology is different from Yi-ology, and it pays more attention to the specific practice of Yijing. Later, Yi-ology refers to the masters who can pinch and calculate in the history of China, such as Jiang Ziya, Zhuge Liang, Liu Bowen and so on.
