Dear (Mr./Ms.) X,
I'm glad that I'm writing to guide you on how to learn Chinese. Firstly, you should master some basic words and expressions and I'm willing to help you with it by writing with you. And I recommend you to watch some of the programmes for Chinenese beginners on CCTV 9, Learn to Speak Chinese, for example.
If you get into trouble studying Chinese, I'm ready to give you a hand as possible as I could.
yours sincerely
