Red Di

The Beidi or Northern Di (Chinese: 北狄; pinyin: Běidí; Wade–Giles: Pei-ti; literally: "Northern Barbarians") was a term referring to various ethnic groups who lived in northern China during the Zhou Dynasty. By the end of the dynasty they were mostly conquered or absorbed by the Chinese.

The ancient Chinese classed their neighbors by compass direction as the Siyi (四夷) "Four Barbarians", comprising the Beidi, Nanman, Dongyi and Xirong. The four names, or combinations of them like 'Yi-Di' are often used to mean "barbarians". The Liji "Record of Rites" details ancient stereotypes about the Siyi "Four Barbarians" surrounding China.

The people of those five regions – the Middle states, and the [Rong], [Yi], (and other wild tribes round them) – had all their several natures, which they could not be made to alter. The tribes on the east were called [Yi]. They had their hair unbound, and tattooed their bodies. Some of them ate their food without its being cooked. Those on the south were called Man. They tattooed their foreheads, and had their feet turned in towards each other. Some of them (also) ate their food without its being cooked. Those on the west were called [Rong]. They had their hair unbound, and wore skins. Some of them did not eat grain-food. Those on the north were called [Di]. They wore skins of animals and birds, and dwelt in caves. Some of them also did not eat grain-food. The people of the Middle states, and of those [Yi], Man, [Rong], and [Di], all had their dwellings, where they lived at ease; their flavours which they preferred; the clothes suitable for them; their proper implements for use; and their vessels which they prepared in abundance. In those five regions, the languages of the people were not mutually intelligible, and their likings and desires were different. To make what was in their minds apprehended, and to communicate their likings and desires, (there were officers) – in the east, called transmitters; in the south, representationists; in the west, [Di-dis]; and in the north, interpreters.

The Di seem to have lived in a horizontal band from the upper Ordos Loop and across northern Shanxi to the state of Yan north of Beijing. This area was a transition zone between the emerging Chinese civilization and the steppe peoples to the north. They seem to have practiced a mixed pastoral, agricultural and hunting economy. Other groups of Di seem to have lived interspersed between the Chinese states. To their north was the emerging steppe society whom the Chinese later called Hu. To the southwest the Rong lived along the northwest frontier of China. The Di and Rong are often associated and both were considered more warlike and less civilized than the Yi and Man.
