Hmm... Just, the PRC, People Republic of China isn't a democracy, and the government doesn't want the country to become democratic. (Taiwan is an exception, independent and democratic since the early ninties)
This is the genius of Guns n Roses, a so called album: Chinese Democracy, because it's a dream! One day maybe, but no today. And waiting for the Chinese Democracy, we have the album.
But the PRC government didn't just forbid the title, but the entire album. But of course, China is a big copyland, and you can find the album not officialy in the country. But the government said: "We don't think Chinese people like this kind od music."
That's it, they rule, and they know perfectly what people do like and don't. hmm, these not elected politicians suck.
