| Dear Tom, I am studying in Beijing now. I have a day off today. Now let me tell you somoething about Bei-jing. In our country people drive cars on the left side of the road, but here in Beijing, on the right side. Many people of London go to work by car, while most people of Beijing go to work by bike. The weather of Beijing is better than ours. It's fine for long here, but we have so many cloudy days in London. Students here work hard at their lessons and a lot of people can speak English. It's a pity that students in our country don't work hard and few people know Chinese. That's all for today. Please write to me soon. Your ever, Peter |
