Their achievements all thanks to Ren, who was a first-class national accordionist at the Air Force Academy of Television Arts Center and the 2015 Beijing Model Winner.
He is one of China's "accordion champions", and is one of the musicians who played before leaders like Chairman Mao Zedong.
Now, he is devoted to teaching the blind, and thanks to him many blind people have found happiness and confidence through music.
The accordion class, which now has more than 30 blind students, was founded in 2007.
And Ren has been teaching it between 9 and 11 am every Wednesday for the past 10 years.
During each class, Ren guides the students and they then practice over and over.
The students cannot see the music scores or the keys. But from their expressions, you know they love music.
