Wear glasses to tell fortune.

There is a blind man who used to be very accurate in fortune telling, but why do you call me stupid and too smart, but I'm not stupid?

A blind fortune teller means that you are actually smart, but you don't know the temperature when you do things, just like a rabbit racing with a tortoise. I think I am sure what to do, so I want to be lazy for a while, but I will lose in the end. Whatever you do, don't be flashy, don't look down on your opponent, or you will lose in the end.
