Dear Li Fei,

How are you? I will have a short holiday next week and have decided to visit Shanghai for a second time. I have booked a room in the Peace Hotel. I hear it is on the Bund(外滩) and has a good view of the famous Huangpu River. I will arrive on the night of March 27 and leave early on March 29. I would like to visit some of the most famous places, such as Nanjing Road and Yu Garden in Chenghuangmiao.

Can you give me some suggestions for my visit to Shanghai? I will have only one day to look around Shanghai. I will be happy if you can make a tour plan for me. Please say hello to Lu Mei. I’m looking forward to your reply.  

Yours,

Sandy
