How to explain the fortune-telling of finger fans?

Generally speaking, an fascinated fortune teller can calculate the front without counting the back, and the back is basically a fabrication, because what happened in front will leave traces, including faces, hands and strange faces. You can see that the baby's face is basically the same. The latter thing is a secret, and most people are not sure. Even if they know, they can't tell the truth. The secret can't be revealed, otherwise it will be condemned by God. Why do you think many blind people are accurate? Because they have been punished all their lives and have been in darkness forever, it doesn't matter. Of course, if someone has a bad omen, it is easy to calculate what will happen to him next, but generally he will not tell the truth. Of course, it may be a coincidence that the aftermath is accurate.
