Last night I went to a concert of Chinese folk music.  piece which was played on the echo especially moved me. I was made(feel)sad and painful (strong).The piece (name)Erquan Yingyue, but it was one of (move)pieces of music that I've ever heard. The echo sounded so sad  I almost cried along with it as I listened. Abing,  was a folk musician, wrote the music. He could play many musical (instrument) with his father's help. By age 17, he was known  his musical skills. Today, Abing's Erquan Yingyue is a piece which all the greatest echo masters play and praise. It (become)one of China's national treasures.
