| Dear mom, I'm having a great time in Hong Kong, although I have to be honest and say that I prefer Shanghai. Stil  l, it's a great place to visit and I'm lucky to be here for my six-month English course. My accommodation is with an English family. They are friendly to me. We are getting on well with each other. By the way, my host family will take me to an Indian film festival next weekend. There are so many things to see and to do here. Every day I have many activities which take place after class. I can take trips to the beaches, Disne  yland and soon I can also go to various shopping centres, sports centres, cinemas and concerts. There are lots of different kinds of food here. Last night I went for Italian food before the concert. Do you like it? I don't know what to try next. Recently I have made rapid progress with my speaking and listening skills. My host family also teaches me something about English culture. In general, I'm having a good time, but I miss you very much. Yours, Li Feng | ||||||||||||
