The fortune teller said that my wife would be rich.

It is impossible to judge whether the fortune teller's words are true or not.

But numerology still exists. The key is to see if this fortune teller really understands and is accurate. For example, trigonometric function is the truth of scientific existence. But if you ask a pupil who doesn't study very well, or who has never studied trigonometry at all, do you believe he can tell you the correct answer?

Besides, whether your daughter-in-law is rich or not has nothing to do with your current hobby of making friends.
