　　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 Yangtze 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
