What does the fortune teller mean when he says I'm from heaven?

Generally, this kind of thing is a secret. Since ancient times, secrets can't be revealed. Generally, if this information is leaked, the person who leaked it is easily punished, which is called losing his life, so most fortune tellers dare not tell you too clearly. In fact, it is easy to atone for your mistakes in heaven, so you need to do more good deeds. If you go to the temple, you may be found by people in heaven, and then you may be doomed.
