Their teaching aim is people-oriented, teaching students in accordance with their aptitude, and the service quality is really acceptable. I am a white boy through and through, but the teacher never thinks that I don't want to teach just because I am a white boy. On the contrary, he will tell me the method more carefully. After class, he will ask me if I have any questions about the course knowledge and explain them until I fully understand the meaning of the course, hoping to help you.
