In February 1918, Johann Gunnar Andersson, a famous Swedish geologist and archaeologist, was told that there were some fossils at what was called Chicken-bone Hill near Zhoukoudian. He was then serving as an adviser on mineral affairs in the Ministry of Agriculture and Commerce of the Chinese Government. He showed much interest and, in the following month, made a survey at the hill where a lot of rodent fossil was collected. The rodent fossil was taken as chicken bones by local people and the Chicken-bone Hill was so named. The latter is nominated later as Locality 6 of the Peking Man Site. This discovery of the locality is not so important, but the survey led to a series of investigations in the region.
In 1921, when Andersson and Otto Zdansky, an Austrian palaeontologist, made another survey at Zhoukoudian, local people informed them that there were more fossils on Dragon Bone Hill. They started an excavation and found some animal fossils and quartz fragments. The excavation brought along the discovery of two human-like teeth. One of them was an upper molar. It was found during the excavation. Another one was an unerupted lower premolar. It was found while preparing the fossil at the Institute of Palaeontology of Upsala University in Sweden. One year later, they continued the excavation at the locality. At the welcome ceremony for the Swedish Prince's visit to China on the 22nd of October in 1926, Andersson announced the discovery of two teeth of early man from Zhoukoudian. The news astonished the scientific world since at that time there had not been any discovery of any such ancient human fossil in China nor any other country in Asia.
