When it comes to mathematics, Wendeng is better. Wendeng started early. One is from Li Zhengyuan, Li Yongle, and the other is from Chen Wendeng. Most of the math review books are from Li Yongle, which is really good. I don't seem to have heard much about Wenhai. Maybe liberal arts are better, such as politics. It also depends on my personal interest, or I like the way of class. We generally say that if you are not good at math, you should choose Du Wen, if you are good at math, you should choose Li Yongle, and if you are good at math, you should choose Wendeng. Get ready!
