I believe it well! People think that Xi 'an is the boss of postgraduate counseling, and Ren Rufen is the boss of national postgraduate political counseling. The math in the university is Huang Qinghua, and I used to trust him. I heard that going to college is because of money! In fact, I have listened to the math class taught by Mr. Wu Zhongxiang. The lectures are very detailed and the ideas for solving problems are very unique. I heard that Huang Qinghuai talked about the whole math class! Well played!
