What is the difference between Wang Wen's copper coin divination and six hexagrams?

Calculation and solution are different.

I am familiar with Liu Yi. Let me tell you something. There are many ways for Liu Yi to start divination, but there is no definite method. But copper coins are often used to start divination, but this is just a way for Liu Yi to start divination. If you are familiar with or understand Zhouyi, you can start divination from all objects near and far, according to your name, number, time, or combination.

The key to divination interpretation is to grasp the relationship between the five elements, the relationship between hexagrams, the relationship between hexagrams and the sun and the moon, and the relationship between hexagrams. If you are familiar with it, it will naturally follow.
