Nickname for the Communist Party (Gòngchǎndǎng 共产党) alluding to the banqueting officials often put on the taxpayer's tab; literally "shared meal party."
Chinese Communist Party officials have become notorious for their propensity to excess. In 2013, the Xinhua-affiliated magazine Ban Yue Tan reported on the problem, interviewing a mayor of a city in central China who said he wined and dined four to five times a day, or more than 1,500 times in a year. Calling the CCP the Dinner Party alludes to gluttonous corruption while simultaneously throwing censors off the trail of sensitive discussion online.

Xi Jinping's anti-corruption campaign is targeting bribery and luxurious spending by government officials. The years-long effort appears to be more about Xi consolidating his power than about fighting corruption, however. Calls for officials to publicly disclose their assets have been squelched by the government.
