What does it mean to hang hands in fortune telling?

Why can fortune telling be accurate? Is there a scientific basis? Should I believe it or not?

Fortune tellers can't be trusted. Because fortune tellers usually say ambiguous words. For example, your appearance is noble, not to mention what it looks like. Or you have a square face. If you say no, it's a round face. You're not sure. He would say, show me your picture. This is a square face and the skeleton is square. Look here. Wait, he can help you turn the square around. If it happens that he is right, you will think wow, he is really good. For example, tiger tooth, if you say you don't have tiger tooth, he can fool you out. For example, most people have tiger teeth, but some people have grown in. Like ordinary teeth, some people have irregular teeth and protruding tiger teeth. And when you talk about fate, most of them are cliches, saying that you are in trouble in your life, but when you are a few years old, you will meet a noble person (you must be comfortable when greeting, you won't care about anything, even if there is a little difference, you will accept it, because everyone wants to be good. When he said you were bad, he took a turning point and lied to you confidently, and you became uncertain. ) for example. If he says you meet someone, your career will be promoted. You will think about who you met in the process of promotion, and then impose an impression on yourself, such as meeting a new friend, and you will feel that he is your noble. In fact, what does promotion have to do with friends? Rely on your own efforts, social relations, and the appreciation and promotion of leaders. But he lied to you. You will go to your friend and think about it. For example, if you haven't been promoted to any official position, he will say that changing jobs is also called promotion, and sweeping stairs can also make the whole company unable to lift its feet. Fortune tellers can listen, but they can't be trusted. Think of it as entertainment, don't take it seriously, and don't believe in fate. Therefore, it depends on human efforts. The road is under your feet.
