Yao is a very nice teacher,  fancy, cute and owns much useful information.
It's highly appreciated for me to be one of his students.
He always keeps patient on our homeworks and on nearly everything.
Things turn out to be harmonious after his dealing.
He always has methods to make the work charming.
Thank you very much for all your helping,
Sincerely yours and Happy New Year,
Mary 小萍
