Central Conservatory of Music.

Because the Central Conservatory of Music’s Level 10 is more difficult than the Musical Conservatory of Music’s Level 10, and the Musical Conservatory of Music’s Level 10 is only equivalent to the Central Conservatory of Music’s Level 9 in difficulty, so the Central Conservatory of Music’s piano grading textbook is the most difficult.

The Central Conservatory of Music, located in Beijing, is a national key university directly under the Ministry of Education of the People's Republic of China and the People's Republic of China. It is a national double first-class construction university and a national 211 Project construction university.
