Why did the fortune teller say that about me?

Fortune telling is not deceptive, but some fortune tellers are deceptive. This person's behavior can be considered deceptive, because fortune telling generally cannot calculate the number of brothers and sisters, because the eight characters have not changed since ancient times, but family planning has appeared. You also said that others have more than ten brothers and sisters or six or seven according to the eight-character theory, which will only make people laugh.
