It is difficult for graduate students majoring in Nanyi Guzheng to take an examination. Now Yan Aihua is the first, and she will retire in two years. Most of the graduate students she takes are from the middle school attached to Nanyi, and viki is also her student. But she is the only double prize winner of Guzheng in China, and the tuition fee charged is higher than that of Teacher Yan. She is an undergraduate in Nanyi, and she stays in school to teach. If the students outside want to take the postgraduate exam in Nanyi, they must go to her first. Anyway, those who have never been to Nanyi should be tolerant not only economically but also psychologically. Different teachers have different teaching methods.
