Zhoukoudian is a village of Fangshan County, about 50 km from Beijing. The nearby Dragon Bone Hill is the home of Peking Man, where Pei Wenzhong, a Chinese paleontologist, excavated a complete fossil skullcap, some teeth and bones of primitive ape-man in 1929. The remains of Peking Man's daily life, hunting and the use of fire were also discovered, which testified the existence of ape-man in Beijing region five hundred thousand years ago. The excavation marks its valuable position in the field of anthropology. Up to now, the remains of Peking Man in Zhoukoudian boast the most plentiful human fossil, the most various species of associated animal and plant fossils in the world and the most extensive research work in then has been carried out.
