My sister, I have a sister. Her name is Li Xin. She is 15 years old now.
Like many other middle school students, she has long black hair, which is always tied up. But she has a specialty. She can play the piano.
She has been learning piano since she was five years old. She likes piano very much, so she can practice all day. She once said that she was very happy playing the piano until now She's a bit of a famous pianist and I'm very proud of her.
