Is fortune telling true or false?

Modern people say that fortune telling is feudal dross, but in fact, there are more people who believe in fortune telling than everyone thinks, so we can say that we can not believe in ghosts and gods, but we can't disrespect them. I once didn't believe in fortune telling and sneered at Sun Hongjun and Lingling Mak, but by chance, I tried it and it was surprisingly accurate. I can only say that China's traditional culture is extensive and profound, and things have their own laws.
