Piano grading test is a series of grading tests for people who learn to play the piano as a standard to evaluate their piano level. In fact, real people of insight know that graded exams are useless. In the Conservatory of Music, all the teachers don't care how many points you got. The grades are for parents, and only parents who play the piano like to watch them. To some extent, this is a hollow reputation. There are thousands of people playing the piano in China, but not many people like and know about music. Ask people which musicians they know, and most people will say Richard Clayderman or Di Yun.
