Why do rural people say not to always do divination, and they can't do it for free?

Always count the blessings, and slowly your luck will not be so good. You can only count what happened or want to know when it happened.

As for free divination, why not? Because it's free, and you didn't give him money anyway, he will definitely talk nonsense with you, and the surname Wang will give you the surname Li. You can make money today, but he tells you that you can't go out today. In this case, do you think it is necessary to believe it? Money is not always accurate, let alone free.
