How can we persuade others not to believe in fortune telling?

Take him to a fortune teller! For example, if he has a child, take him to a fortune teller and let him choose who to look for. Then ask him to ask the fortune teller that he has never given birth to a child after marriage, and ask him when he will give birth to a child, whether it is a boy or a girl. In this way, the lie of fortune telling was discovered.
