回复：Rick Steves 的确是很好的参考书

Yup, i carried all those books you mentioned to that trip, totally 8. no time to do any homework bef the flight. finally found 1 or 2 books at very high utilization ratio. If not driving, some books are not very helpful.

also, you may think borrow those books from library, at least work for me very well. then no need to do the copy work.

actually you should think writing tour guide book, Chinese version. serious suggestion.
