So, the Mayan thing is snowballing in China, stimulating panic buying of necessities, shotgun marriages and raids on personal bank accounts. Check out the fellow who's manufacturing survival arks at around £175,000 a pop, too. It's worth bearing in mind here that expressed as a percentage of the population, the number of people in China who believe this stuff may be identical to the percentage in the West, but the sheer numbers involved in a Chinese context make it a mass market rather than a niche market, and so one can expect businesses to respond accordingly.
There's also the fact that people, including the fellow building the arks, seems to have got the actualy Mayan prophecies confused with the Roland Emmerich film 2012, where China builds a whole series of arks to save humanity from catastrophic flooding. So it's kind of patriotic, too.
Having said that, there's a bit of speculation around that Mayan Apocalypse is shortly going to join June 4 and Dalai Lama as a censored term in the Sinosphere.
