You're most welcome for the advice, Chenxi.
With regards to what books you should read, well, that's a rather subjective area. Read what interests you. If you aren't sure what to choose, ask the salesperson at your local English bookstore. They will be able to show you which books are popular and/or required reading for English majors in China.
All the best.
P.S. At the moment I am reading a book that I initially thought wouldn't be my cup of tea, but has turned out to be what I feel is one of the most well-written prose I've ever read! It's "Zorro" by Isabel Allende. (It was bought in Shanghai.)
