Dear Li Lin,

Glad to recive your message. At present I am writing to tell you how to attain a highly readable composition.

First and foremost, an effective way, to the best of my knowledge, is to collect classic words and sentences, processing them over and over until you bear them in mind. The more vocabulary you accumulate, the more freely you can apply them when writing. What’s more, reciting fantastic possible versions and sentence structures worth imitating can get you to make enough preparations in advance. Last but not the least, it is a good reward to practise writing. Only by exercising can you put to use what you have gathered.

Don’t hesitate to ask for more if you have any questions. Look forward to hearing from you.

Yours sincerely,

Li Hua
