Can you believe what the blind fortune teller who plays erhu said?

Don't believe that. If he can predict the future, he will stay at home and count money, and he will show off like a monkey. A blind person is generally not completely blind, that is, he has 0. Vision below 5, understand why he can fool success. There are still a few problems that we should pay attention to. Question 1, how did he learn erhu when he was blind? Question 2: What should he do when he goes to the toilet, how to wipe his ass, what should he do if he takes less paper and tears it, and what should he do if he gets it?
