The interesting thing is that, even though the Chinese quickly took these characters off the park when news broke on it, the Chinese themselves have a very casual attitude towards copyrights. My favorite quote by a Chinese housewife: "I don’t understand why that is such a big problem. Shouldn’t others be able to use those characters besides [Disney]?" Uh, no. That's what copyright means.
