For example, when a child tells a person who can draw symbols, tell fortune and watch feng shui, he will change. It is said that he will give others the blessings they deserve.

Nonsense. I also believe this lie. And don't tell all the truth to such people, but leave three points in case he cheats money. Even if the fortune teller is very good, he won't tell you everything he knows, because secrets can't be revealed. Everyone's date of birth is doomed at the moment of birth. This is called destiny, and destiny cannot be violated. But fate is in everyone's own hands.
