安特生
In 1921, near the city of Beijing (also romanised as Peking), Swedish archaeologist Johan Gunnar Andersson was teaching Austrian palaeontologist Otto Zdansky and American archaeologist Walter Granger how to work on Chinese sites near the village of Zhoukoudian ("shop on the Zhoukou”) at the Chi Ku Shan ("Chicken Bone Hill") locality, when they were advised by local quarrymen to dig at the nearby Longgushan ("Dragon Bone Hill") locality. Zdansky found the first human teeth in the site that year, but only reported it in 1926. In 1927, Swedish archaeological student Bergir Bohlin extracted another tooth.
