I'm a student of Zhiyuan Tree now, and I'm going to take an examination of Tokyo University, which ranks first in Japan. To tell the truth, I'm still under a lot of pressure. But the teachers in Zhiyuan's book are not like others, they only teach and don't care. For example, when I am under great study pressure, the teacher will change the teaching mode, chat with me after class and do psychological counseling. In my place, Zhiyuan Tree is the most famous, so let alone the environment. I suggest you try.
