I’ve been to many places in china . for example , HK , Peking , Hangzhou , Nanjing and so on .HK is a busy city , everyone here every minute doing their works , they even haven’t free time ! but in Hangzhou , there’s no too much work to do , everyone feels relaxed , and this is a beautiful city , I want to go to the beauty west lake again . the second largest city is Peking , there , you can visit the Palace Museum or the Great Wall , that’s wonderful !
Now , let me tell you about my family . in my family there are three people , my father ,my mother and I . my father is a teacher and my mother is a businesswoman . my father always cooks diner for us everyday and after meal my mother washes the tableware . where am I ? of course , I’m doing my homework . : ]

Sometime , I think about my future . I dream to be a businessman , because if I successful , I’ll have many more money . It’s only my dream ,but I haven’t known what I would to be . : ]
