Lang Lang and Haochen Zhang

In an blog post by Lang Lang in 2006, after teaching Haochen Zhang at Curtis:

I’m putting up a picture taken recently. I was giving a master class, and the kid in the picture is a Chinese student at Curtis, named Haochen Zhang. He’s very smart and has very good comprehension to music. He plays very well!

In original Chinese:

附上一张我的近照。这是在Curtis给中国学生章昊辰上课。他很聪明，对音乐的领会力很强，弹得很好！
