Dear Li Lei,
尊敬的李磊：，
I haven't heard from you for a long time. I'm glad to tell you that I'll visit Beijing this summer vacation. It is said that Beijing is a great city with a long history and more changes have taken place since the 2008 Olympic Games. I would like to know something about Beijing, such as places of interest, the environment, traffic and people there.
我好久没有你的消息了。我很高兴告诉你我今年暑假要去北京。据说北京是一座历史悠久的大城市，自2008年奥运会以来发生了许多变化。我想了解一些关于北京的情况，如名胜、环境、交通和那里的人。
I'm looking forward to hearing from you soon.
我期待着很快收到你的来信。
Yours,
你的，
Tommy
