Or you can borrow them from a library. Don't know about the mainland or other places but there are lots of Jin Yong novels in libraries (public libraries and school libraries) in HK.

Who is the most beautiful girl by Louis Cha. ?

These traditional ideology and culture are respectively expressed in Jin Yong's different works in different stage of writing.

Compared with Jin Yong, Go Long displayed a different style in his novels---the characters seem to interact with each other more and the characters seem to express much more emotion.

I'm also reading Jin Yong, it is great (I have no comparison, never read any other kungfu novels), but not easy.
