Why do some men have names like women?

Reason 1: My parents want a boy, but they are disappointed. They all chose a name to support her as a boy, and vice versa. This is a little belief left by feudal superstition in the old society.

Reason 2: The fortune teller said: Your son needs a girl's name to raise, or he will get sick easily or something.

Reason 3: My parents are poor in culture and don't have many concepts about names. Just remember them simply.
