Excuse me, what do you mean by going out and changing your name to survive?

It means: you should go out instead of staying at home, changing your name and surname and seeking the safety of your life.

There is nothing wrong with not believing, but it is better not to believe if you believe, because fate is not in the hands of fortune tellers. "Wealth is in the sky, life and death depend on fate" should be changed to wealth in oneself.
