The Monument to the People &39; s Heroes is the first state-level public art project after the founding of New China, and also the largest monument in Chinese history. It gathered a large number of the best literary and historical experts, architects and artists in China at that time, such as Zheng Zhenduo, Wu Zuoren, Liang Sicheng and Liu Kaiqu. From September 30, 1949, when Chairman Mao laid the foundation himself, to May 1, 1958, when it was officially completed, it was the longest time-consuming large-scale art project since the founding of New China.
