What schools are there in the Book of Changes? What are the differences?

Generally speaking, I ching is divided into rationalism and technicalism.

The rationalist school also studies the Book of Changes as a philosophy. Confucius is the first school of the Book of Changes. He first put the Book of Changes into the philosophical category. Of course, rationalism is also a fortune teller. For example, Confucius himself said that he knew his destiny at the age of 50, which means that he didn't start reading the Book of Changes until he was 50. A disciple asked Confucius, who also believed in divination. Confucius said that nine times out of ten, he was right. In other words, according to Confucius, nine times out of ten it is true.

Art schools simply use the Book of Changes to tell fortune, which originated at the earliest and is also the fundamental reason for the emergence of the Book of Changes. Later, Zhang Jingfang invented the six-legged armor of Han Dynasty and the plum blossom easy number of Shao Kang Festival.
