Why did the ancients invent the Book of Changes, and now people still don't fully understand it?

The hardest thing about the Book of Changes is change, which is why everyone's interpretation sounds reasonable. Everyone has a different experience after reading it. In fact, I think the Book of Changes not only includes philosophy, astronomy and human environment, but also summarizes everything, which is great. Including some common things in life, are related to the Book of Changes. For example, why the Ninth Five-Year Plan comes first and not 96979899? These all have a certain saying. Just a dry divination contains enough truth for a person to eat for a lifetime. If you can use it properly, I believe you can make a lot of money. It even affects your family, career and life. It's no exaggeration.

Are modern people more stupid than ancient people? Obviously impossible. Then why can't modern people play the Book of Changes? First of all, I personally think the Book of Changes is in a state of change. You have no idea what your ancestors wanted to express when they created the Book of Changes, and how to play the Book of Changes is only imposed by modern people. So, I read the original Book of Changes without even reading my notes. In addition to the above reasons, I think there are a few points, just feelings.

Without the Book of Changes, I vaguely feel that there seems to be something very important missing in the Book of Changes. This thing is the true soul of the Book of Changes. It seems that someone is deliberately hiding it, and I can clearly feel that there is something missing from the Book of Changes. This feeling is getting higher and higher with the depth of my enlightenment. I used to think I was an illusion, but recently I don't think so.

One-dimensional point, two-dimensional surface, three-dimensional body. This is the level of thinking. When your mind is in one dimension, it is just a point, and in two dimensions, it is a face. And the three-dimensional world in which human beings currently live is the three-dimensional world. How do you deny that there will be no four-dimensional and five-dimensional world? Let me give you a simple example. If you look at a plane painting now, you can understand it from a two-dimensional perspective. But if you look at a three-dimensional painting from a two-dimensional perspective, you will never understand it and feel at sixes and sevens. The three dimensions are the same.
