From Los Angeles Times (link):
LAST FALL, a magazine editor in Beijing named Li Datong decided to feature a historical article about Taiwan in his weekly, Freezing Point. It was a straightforward account of Taiwan’s harsh political repression in the 1950s and how democratically elected legislators are coping with that history.
In China, where Taiwan is routinely criticized, the article passed the usual censors at the Ministry of Propaganda, which screens all of the nation’s publications. Once it was published in November, however, sophisticated readers could see that the article drew a clear if unstated contrast between politics in Taiwan and in China. One is now a democracy that is openly debating past repression, and the other is not. The article was eagerly passed around by liberal intellectuals in Beijing who enjoy nothing more than a chance to chuckle when a subversive article sneaks into print.
