| Dear Dad and Mum, How are you? I hope you are well. I have been in Beijing for about two months and I enjoy living here very much. The weather here is pretty cold and people are friendly. I work and study with Chinese students. On the weekends I play different kinds of sports. Ping-pong is one of the most popular sports here. Now, I am learning playing ping-pong from my best friend Li Ming. He is very good at playing it. He also asks me to teach him to play basketball. I also learn Chinese from my classmates and at the same time teach them Japanese. Last week, I visited many places of interest. They are really great. I like them very much. My favourite places are the Bird's Nest and the Great Wall. It is amazing, isn't it? I saw Beijing Opera with my teacher yesterday and enjoyed delicious Chinese food. Beijing roast duck is the most delicious. Now I have known more about Chinese history. Hope to meet you soon. Best wishes! Yours, Tom | ||||||||||
