稳腚 (wěn dìng): stable bottomHu Jintao’s leadership, the Communist Party has gone to great lengths to “maintain stability” in society. Using this rationale, protests are squelched, political dissidents are controlled, and the media is censored.
Netizens joke that China’s leaders’ obsession with “social stability” is a just a pretext for insuring the stability of their “bottoms” on the thrones of power. “When the officials’ bottoms are stable,” goes a popular saying online, “society is unstable. When the officials’ bottoms are unstable, then society is stable” (官员稳腚了，社会就不稳定了；官员不稳腚了，社会就稳定了).
