Why did the fortune teller say he wanted to have a boy? Why not?

There are three possibilities: one is that the fortune teller knows it's a girl, but doesn't tell you it's a girl, because many people will have an abortion when they know it's a girl, so the fortune teller is tantamount to indirect murder.

One is a fortune teller. It's really not allowed.

One is a fortune teller who knows that it is a girl and a boy in order not to make pregnant women have a psychological burden.
