How to calculate the Book of Changes with coins?

It's best to use six ancient coins (the best for Qianlong Bao Tong) to shake the hexagrams, which is the six-hexagram prediction method.

If not, you can also shake it with a circulating copper coin (50 cents) and record the reverse side as Yin or Yang, and then the divination obtained is the original divination, and then you can get a change from the original divination, and then draw a conclusion according to the 64 divination words in the Book of Changes.
