1、Hi, Tom

I've been in Xuzhou as an exchange student for a week．I really enjoy my stay here．Don't worry!

Here in Xuzhou things are quite different from the USA．For example, there are so many people! On my first day at school，they asked me to speak in front of the whole school．Guess，Tom，how many students? More than 2,000! That’s the population of our town! I'm also surprised by the amount of food on the table．There are so many dishes．Yesterday evening I ate so much that I could hardly walk! There are not many clubs here．All the students seem to be busy with their studies．

Please write to me soon．

Best wishes,

Bill
