Hmm... To those talking about plagiarism, I would like to point out that before we had copyright law in the west (which only even began to make sense once we had printing presses; before then you'd have to copy anything by hand, so the "value" of a given work was regardless mostly from the time and labour needed to do that) it was standard practice to lift large sections of whatever you were writing from other authors, or to steal stories from other people, for instance in travelogues. Why is it unethical to copy and embellish upon someone else's idea without attribution?—that idea doesn't come out of nowhere; in a society based primarily on oral storytelling, it makes little sense at all.
I don't think it's dastardly at all that China hasn't fully signed on to the same ideas of "ownership of ideas" that the West has. And while lately they've been pulled more in this direction, but I don't feel obliged to knock authors who want to stick to the old, more chaotic ways.
For authors in countries with stronger copyright protection, I'll be much more critical of plagiarism simply because it gives an unfair advantage when everyone else has been playing by copyright rules. (And no one here has been born in a time where we weren't like that.)
