It shouldn't surprise anyone that there is censorship in China. That includes, of course, the press and the internet. The authorities euphemistically call this censorship "promoting harmony". One of the objects of censorship has been profanity. Lovers of free speech have been out-raged. Beginning in 2009 the "netizens" began an anti-censorship campaign using homophones. An entire group of memes and characters with intricate stories, songs, and ecosystems has been set up on the internet. Many of these words are homophones for obscenities: including the word for Grass-Mud-Horse. In the fictional world of the Grass-Mud-Horse, aka the alpaca, the Grass-Mud-Horse fights the red river crab, Harmony. The purpose is to drive the relentless, red river crab (harmony) out of the Grass-Mud-Horse's home land. That is a VERY brief explanation of the story...there is much more information online. Beware: It IS R rated!
