话题表达
One possible version：
Dear John，
I am so glad to hear from you. Learning that you are working on Chinese， I strongly recommend you the novel Journey to the West.
The novel is one of the Four Great Classical Novels of Chinese literature. It is about Monk Tang and his three disciples traveling west to India in search of Buddhist scriptures. The novel will open the way to Chinese values and history. You will get a better understanding of Chinese culture. The novel offers a mixture of adventure and comedy， so while enjoying reading， you will surprisingly find you can speak and write in Chinese better.
I do hope you keep reading. I’m sure you will achieve great progress in learning Chinese.
Best wishes to you.
Yours，
Li Hua
