Dear Dave,
　　I'm happy to be your pen pal. I'd like to tell you something
　　about China.
　　China is the biggest country in Asia. It' s almost as big as the
　　USA. China has the biggest population in the world. The people
　　here are friendly and hard-working. The Y angtze River is one of
　　the longest rivers in the world. China is over 5000 years old. It
　　has a much longer history than the US. The Qomolangma is the
　　highest mountain in the world.
　　I love China very much. Welcome to China and play with me.
　　Yours
　　Li Lei
