     On December 23rd, 2008, Niu Niu held a piano concert at the National Grand Theatre (国家大剧院). He is

a talented boy who plays the piano very well. As an eleven-year-old boy, he became the  ①  pianist to perform

a solo concert (独奏音乐会) at the theatre.

     Niu Niu was born into a musical family in Xiamen.③ His father Zhang was a piano teacher. Niu Niu grew

up listening to his father's students playing the piano. At just three years old, 牛牛也请求爸爸教他弹钢琴②。

     "I gave Niu Niu some sheet music (活页乐谱) when he first played the piano. To my surprise, he played

nearly 80 percent correctly," said the father. He used to think that 3 years old is too young to learn playing the

piano, but Niu Niu changed his mind. He continued to allow Niu Niu to watch his teaching and gave him more

sheet music to play.
