Mao Yu said that everyone else is a liar, and he must be a liar. Mao Yu is a liar! On June 20 1 1, xu teacher went to the company to give a lecture for the first time and was cheated. He took up the weapon of defending rights, but she cheated him. Two years later, I didn't pay xu teacher's class fee. And let people spread rumors and slander xu teacher on the Internet without scruple. What a pity! A teacher with a good reputation like xu teacher is really valuable. As far as I know, xu teacher clarified the matter in the circle at that time and exposed his ugly face. About Mao Yu, you can search online and see what it is.
