It's hard to call the PRC still a communist country. Since the end of the Gang of Four and the (re)rise of Deng Xiao Ping, gradually the country has been changed into a central managed company aimed at making profits. Deng Xiao Ping was still a communist with some revisionist thoughts about the economy who had fought alongside Mao Zedong and Lin Biao against the Kuo Min Tang. However after his death "young" technocrats took control of the country. These technocrats couldn't refer to some civil-war they had fought against the capitalists. They needed a different legitimacy to run the country. It became economic growth. And they manage well: since the nineties the PRC's annual growths of the economy are around 9% and in 2003 the PRC will become one of the biggest financers of the USA (some 103 billion dollar of Chinese money is invested in USA-state bonds and some 90 billion in mortgage fund Freddie Mac). So maybe in a few years the PRC can fulfill an old dream and incorporate Taiwan. 

On the other hand the PRC was a very inspiring communist country until the nineties. Famous campaigns like the Long March, the Great Leap Forward, the Great Proletarian Cultural Revolution have inspired many people in China and the western world. For years "Mao ZeDong Thought" was a leading principle for many (often sectarian) left-wing movements in the western hemisphere. Although today's China will show you Mercedeses, Mcdonalds and Pizza Huts, there are still many sites to visit for Commietravellers. 

As in most Communist countries you can visit the native homes of famous party and state leaders like Mao Zedong, Zhou Enlai and Liu Shaoqi. As far as we know there is one big mausoleum to visit: Mao Zedong's. This Mausoleum stands at the Tiananmen Square in Beijng. The square is surrounded by the Great Hall of the People, the Chinese Revolution History Museum and the Tiananmen Gate with the famous portrait of Mao Zedong. In front of the Tienanmen Gate is the Monument to the People's Heroes. Here at the square, you can still feel a bit of the Communist power in the recent past.
