What is the difference between divination in Zhouyi and folk fortune telling?

The so-called folk fortune-telling divination comes from Zhouyi! It turns out that divination, divination and divination are all so-called fortune telling. One can use turtle shells, drill a hole and burn them, which are basically used by emperors. Hehe, it's not folk stuff. Another way is to use grass. The Book of Changes has fifty great poems and nine out of forty uses. This paragraph is about how to tell fortune with grass, but this method is very good. Inside the outer circle, it represents the round sky. Three coppers can only represent one hexagram, and it can also tell Shaoyang Lao Yang. So this is the so-called folk fortune telling. To put it bluntly, it is from Zhouyi, and the hexagrams are calculated. Looking back, I still have to look at Zhouyi. Otherwise, just look at the hexagrams and don't know what it means! Hehe, do you understand?
