What does fortune-telling wisdom mean?

I think this question is a matter of different opinions.

Some fortune tellers became monks halfway and wanted to earn a bite to eat, so they started this business; Some fortune tellers are born to tell people's fortune, and these people are often more accurate. If you are looking for a fortune teller, I think this kind of naming your baby is also half a bucket of water; But if you are looking for the kind of person who is very god, the situation is different.

I have a friend's uncle, who specializes in showing people eight characters, which is super accurate. When my friend was born, her parents didn't pay much attention to her name, so they gave her a name "Xi". It wasn't long before her parents found out that my friend was super grumpy and always quarreled with his family. Later her parents asked her uncle for help to see what was going on. Her uncle looked at her constellation and said that there are three dogs in my friend's constellation, which is very fierce. I'm not sure about this word (she is too professional and I don't quite understand it). That's probably what it means anyway). Later, my friend's parents changed her name from "Sunrise" to "Xi". Later, my friend's personality was much better ... In fact, this kind of thing is really strange, and I think believe it or not.
