What are the stresses and taboos of fortune telling?

There is a certain fee for fortune telling.

Don't reveal the secret. If you reveal the secret, you will get some retribution, so you can't say everything.

Fortune telling has etiquette. You should purify yourself, burn incense, recite incantations and ask God. You can't pay for incense yourself. There is no charge, and there is a reward. There is an old saying that divination cannot be empty, that is, there is a charge.
