thumb|"Barbarians" according to Chinese cosmology. Those in the east were called [[Dongyi (東夷), those in the west
Xirong (西戎), those in the south
Nanman (南蠻), and those in the north Beidi (北狄).]]
Beidi () is a term that originally denoted an ancient
ethnic group (Di) but was used to refer to all non-
Han Chinese ethnic groups in today's Northern
China,
Mongolia, and
Siberia, especially those who lived beyond the
Great Wall of China, such as
Xiongnu (),
Xianbei (),
Khitan (), and
Mongols (), etc. In certain periods of Chinese history, from the Han people's view points, seeing from the inside of the Great Wall, those on the outside were considered to be barbarians.
