Dear Li Fang,

     I have been in England for three months now. I hope you don't think I've forgotten you. There have

been so many places to visit and so many things to do that I've not had Lunch time to write letters.  

     I shall soon start my studies at King's College. So far I've been learning about British ways of living. I

won't tell you about London, because there are plenty of books you can read and plenty of pictures you

can enjoy. I'm sure you'll be more interested to know what I think about the life here.

    I find some of the customs new and interesting. People here do not shake hands as much as we do in

China. During the first few weeks I was often surprised because people did not put out their hands when

I met them. Men raise their hats to women but not to each other.

                                                                                                 Yours,

                                                                                                        Linlin
