What does the fortune-telling circle mean?

Introduction to character testing and fortune telling

Legend has it that there is a very distant place called the Land of Hua Xu, which is tens of millions of miles northwest of China, and people can't get there anyway. There is no leader in that country, and all people let nature take its course. They can enter the water without drowning, the fire is not hot, and there is no pain ... In this land, there is a girl named Hua Xushi who has been to the East. On the edge of an infinitely beautiful swamp, she found a huge footprint and stepped on it with her foot. As soon as she stepped on it, she felt something inexplicable flow into her body. Later, she became pregnant and gave birth to a son named "Fuxi". The huge footprints on the edge of the swamp were left by Thor, and later I learned that this swamp was called "Razer". Thor is a god with the head of a dragon. So Fuxi looks like a "human-faced snake" like Thor. Later, Fuxi became the Emperor of Heaven. He "looked at the sky and the ground, looked at the law and looked at the ground, observed the culture of birds and animals and the suitability of the ground, and took things near and far away, so he started gossip." Eight symbols include all kinds of phenomena in the universe, so people use them to record all kinds of things that happen in their lives ... Divination by measuring characters comes from early divination, which is a kind of foreknowledge, that is, using all-encompassing eight symbols (gossip) for divination and fortune telling. Divination and fortune-telling originated from Shamanism (non-Manchu Shamanism), and religious scholars collectively referred to early religions as Shamanism.
