Fortune tellers generally like to say that others will go to jail?

The probability of this miscalculation is quite large. Maybe the fortune teller is not knowledgeable enough. He saw the tight encirclement in the eight characters, and he didn't know whether he was in prison or had a net in his head. To be on the safe side, he will change it if he has it, and encourage him to change it if he doesn't. Of course, there are also people who scare people to cheat money to eliminate disasters, but not all fortune tellers are cultivated this way, and some are indeed careless in knowledge and miscalculated.
