Although Mr. Yau is blind, can’t see anything, I think he is a good teacher. He can teach us many things that we can’t learn from books. Also, he share his experiences of how a blind person’s life. I am proud of Mr. Yau, because he can’t see anything, but he still can be a good teacher, teaching us English, also he knows how to control a computer by his own controller. It’s fantastic! I hope Mr. Yau can be a very success teacher, although he can’t see anything, he can still life so perfect.
