Dear Tony,
Thank you very much your letter. Shanghai beautiful! I like Shanghai I like China. Now I’m fine and I’m busy my lessons. I have seven classes every day. There are in the morning and three in the afternoon. I have nine subjects this term. I like math, biology and history. My subject is science, because it’s very interesting. Yes, my English is very , and I like it, but I like Chinese, because it is too difficult me, and I can’t learn it well. Do you play soccer? Can you Chinese? I hope you can come to China one day.
Bob
