If I have a white hair and it's gone, what does it mean?

Long white hair on the mouth indicates that something has happened recently. No, it means that things have passed and everything is fine.

Wow, very professional. I can guess from this. Did you graduate from "Nonsense" College? What is your major? So mysterious and professional?

What do you mean? This is just a physiological phenomenon. If I have to tell it what this means, I can only say that this kind of white hair is an individual mutation. Do you still believe in these so-called fortune tellers in such an era of advanced technology? They say disaster comes from the mouth, but I saw you say that hair grows in the mouth. If you say it grows on your hands, it will say that troubles come from your hands. If you believe this, then all your books have been read for nothing.
