Yi-ology and fortune telling _ the difference between Yi-ology and fortune telling

What's the difference between fortune telling and Zhouyi?

The Book of Changes is a very philosophical book in ancient China. Fortune-telling is at best a derivative of Yi. In addition, because some Jianghu artists who are not proficient in learning make things up, many of them are deceptive. Moreover, in order to make guests happy, fortune tellers nowadays will report good news instead of bad news, and all of them exaggerate the good parts, leading to absurdity and false superstition.
