Part of the Chinese online discussion is escaping censorship by turning to word play, the New York Times reports:

<<The grass-mud horse is an example of something that, in China's authoritarian system, passes as subversive behavior. Conceived as an impish protest against censorship, the foul-named little horse has not merely made government censors look ridiculous, although it has surely done that.

It has also raised real questions about China's ability to stanch the flow of information over the Internet – a project on which the Chinese government already has expended untold riches, and written countless software algorithms to weed deviant thought from the world's largest cyber-community.>>
