dear john,i am exciting to hear that you will come to visit our city next month.Now let me tell you something difference you may meet here.To begin with,the weather here is totally different from what in your country.It doesn't rain very often and whenever it did,it rains heavily.So you'd better always to bring a raincoat.Other big difference is food.You have to try to get used to it,and learn how to use chopsticks.I'm sure you will have good time here.Finally,please bring an American map to me if possible.Thank you.I'm looking forward to meet you.
