Dear Mum and Dad,
I'm here in Beijing to write to you telling about my experiences.
I'm having a good time here.Some Chinese students and I learn form one another,and I have visited many places of interest in Beijing,such as the Great Wall,the Forbidden City and so on.Wow,they are so fantastic.I have to say that I enjoy my life here a lot.
How are you doing?Miss you both very much!
Best wishes!
Yours,
