Is it illegal to tell a fortune once?

The law does not say that fortune telling is illegal, but it is illegal to cheat you or commit other illegal acts in the process of fortune telling, but fortune telling itself is not illegal.

(1) Fortune-telling is a superstitious activity among the people in principle. It's just a little deception if believers want to.

(2) Of course, if fortune telling is involved as a criminal means, it may be suspected of many crimes, such as theft, fraud, extortion and so on.
