Dear Justin,
I feel really sorry to tell you that I cannot keep you company and show you around my city next month during your stay here, for there will be an important exam. But you don’t have to worry about your accommodations here in my city. I have already reserved a room in Weifang Hotel, which is at No.34 Dongfeng Street and you can easily check in by the name on your passport. For more information about the hotel, you can call the reception desk at 0536-87654321.
Let me know if you need any help and wish you a pleasant journey and enjoy an adventure in my hometown.
Yours,
Li Hua
