Dear Sarah,
Thanks for your letter. I'm glad that you can come on Sunday. Now I tell you how to get to my house. First, you can take the No. 1 bus at the bus stop, and get off at people's Park. Then go straight for 15 minutes and you can see a library.
Beside the library, there is a tall white building. It's the science museum. Go straight and turn left at a pet hospital. My home is next to the pet hospital. It's a small but beautiful house. Please come soon. I miss you very much.
Yours,
Chen Jie
