K-POP (韩国流行音乐) culture is popular in China. The 20-year-old singer IU proves (证明) that again. On March 21, IU is going to have her Modern Times concert in Shanghai. But she is so hot that tickets are really hard to get. Since her first show in 2008, IU has become famous for her high notes (高音) and sweet look. People in South Korea call her the “Nation’s Little Sister”. And her Chinese fans are full of expectations for her concert in China. IU is not only bringing her classic songs but also some games to play with all the fans. Sounds interesting!21ST
