I am David and I am a British boy. I have got a lot of friends in China. They all have their hobbies. Daming' s hobby is playing basketball. He often plays basketball in the playground after school. Li Ming likes playing chess. He sometimes plays with his grandpa at the weekend. Lingling loves watching TV and playing computer games. I often play with them. They also help me learn Chinese. But it's not easy for me. My hobby is collecting stamps. I have got thirty Chinese stamps. They are all from different famous places. Only one of them has got a picture of the Huangshan Mountain on it. It' s beautiful and I like it very much.
