Dear David.
Please come to my home for dinner at six this evening. Here is a map to help you find my house. Take Bus No. 22 and get off at Guangming Road. Walk along the road and turn right at the first crossing. Now you're on Xiangyang Road. Walk about five minutes and then you can see four houses on your left. The third one is mine. You can't miss it.
Yours,
Li Lei
