Dear Peter,
I'm very glad to receive your letter,in which you asked me how to learn Chinese well.I am going to give you some advice which can help you improve your Chinese as soon as possible.
First of all,it's widely acknowledged that accumulation is of great importance to learn a language.You'better broaden your vocabulary first.secondly,it's also a good way to listen to Chinese songs more.Besides.you are expected to have communitions with native Chinese people so as to speak Chinese fluently.What's more,making a hair of keeping diary is also a good idea.
To help you to improve your Chinese,I'll write to you every week to practice your handwriting.In addition.I'm going to speak to you in Chinese every day to help you with your spoken Chinese.
I hope you can take my suggestions into consideration.If so,I think it won't be long before you make great progress in Chinese.
Yours sincerely
Lihua
