The Communist pantheon of Mao, Zhu De, Zhou Enlai, and Liu Shaoqi all lived here at one time or another, but this was also the site of the famous Yan'an Forum on Literature and Art in May 1942. The forum, in which Mao argued that art and literature should serve the people, was to have a profound impact on the arts in China in the following decades. Visitors to Mao's room toss cigarettes onto the former leader's bed as a sign of respect.
