Dear John,
I am glad to hear that I will share an apartment with you. This letter is to tell you something about my living habits. Besides, since you are a local student, I would like to ask some advice about living there.
First, my living habit is simple and regular, so I think it is easy to get along well with you. The only one which should notice you in advance is that I usually go to bed early, thus during the sleep time, I do not want to be disturbed by any noise. Second, as the climate of your country is different from ours, I want to know which clothes is suitable for me to take during this time.
I am looking forward to your replay as soon as possible.
Sincerely yours,
Li Ming
