Last night I went to a concert of Chinese folk music．（46）　　piece which was played on the erhu especially moved me．I was made （47）　　（feel） sad and painful （48）　_　（strong）．The piece （49）　　（name） Erquan Yingyue，but it was one of （50）　_　（move） pieces of music that I've ever heard．The erhu sounded so sad （51）　　I almost cried along with it as I listened．Abing（52）　　was a folk musician wrote the music．He could play many musical（53）　　（instrument） with his father's help．By age 17，he was known（54）　　 his musical skills．Today，Abing's Erquan Yingyue is a piece which all the greatest Erhu masters play and praise．It （55）　　（ become ） one of China's．
