I have a sister. Her name is Li Xin. She is fifteen years old now. Like many other middle school students, she has black long hair and always ties them up. But she has a specialty that she can play piano very well. She began to learn the piano at the age of five. She likes piano very much, so she can practice it all the day. She once said that she is happy when playing piano. Until now, she has performed in many places. She is a piano player of some renown. I am proud of her.
