What's the use of divination?

Arithmetic also means calculation, through which results can be obtained, just like doing complex math problems. Good math can work out the correct results, and poor math will certainly make mistakes. For example, if a gun is aimed at an object, what will happen to that object if it is fired? According to the bullet and speed, what is the result of the object being hit can be calculated, which is also called calculation. One of my relatives also likes these things. For example, he said that if a seed is planted on fertile land, it will grow well in the future. If planted in saline-alkali land, it will not grow well. To put it bluntly, they are all natural laws, and people are also included in the natural laws. To put it more deeply, this is the "Tao". Some things, but in the case that science can't explain them, are all forgotten by superstition. Once they can be explained by science, they are called science. . . . For example, in ancient times, there were ghosts living in wells, and people who went down were strangled by ghosts. Now it can be explained scientifically, which turned out to be caused by lack of oxygen and gas in the well. So at that time, if you don't believe in ghosts, whoever goes down will die. Most divination is a word game. For example, my sister-in-law asked someone for divination, and the other party said that your family had been stabbed, and it was twice. My sister-in-law thought about it carefully. My mother had an operation and did have a knife. I turned to my wife and said, "Your mother's house was stabbed twice. If you think about it carefully, it must be true. " The wife carefully thought about it, and the brother-in-law broke his finger and did move the knife. . . . . So these are all word games. Even if there is one who can be right, it is not a simple person.
