Not expensive, about the same price. The current training institutions are basically college students. This is nothing, because each class of training institutions is only 60, which is generally divided into 50-50 with teachers. A good teacher doesn't want to take such a cheap class, but it's too expensive and the money can't be collected from the students. The basic situation is like this! Now I am a senior in Xi 'an Conservatory of Music, and I have a class of 200 yuan. I have followed many teachers, and she plays the best. This is not a college student or something, but how much she has learned! I sincerely hope to adopt it!
