Is Zhouyi divination very effective?

Zhouyi is a great scientific work, not a book of divination, but there are some contents about divination in the book. The so-called "big things are easier said than done." If you want to know whether it's accurate or not, I'll tell you the simplest method: toss a coin with both sides six times, and then predict what you want to predict according to the interpretation of the sixty-four hexagrams of Fuxi in Zhouyi. This method is not very formal, but the method in Yijing is extremely complicated, which is not conducive to operation.
