Among the math teachers, Zhang Wei and Yang Chao are humorous in their teaching styles. In their words, there is no "urine point" and it is very responsible. They often say, "Don't worry about memory, but concentrate on understanding. Remember to stay with me when I finish. . . ""You must tell me. . . "By analogy, they don't use PPT in class, but write on the blackboard with a tablet and cast it on the big screen. After class, you can interact with them through Sina Weibo, and you can ask them any questions.

Most importantly, Mr. Zhang Wei will mark the papers for the students taking the exam in Beijing at Peking University. In his class, he will learn something about how they judge papers and how to increase their ability to get more marks without knowing or knowing. If you take an exam in Beijing, you have to take his class.
