Xiongnu
The Xiongnu () were a confederation of nomadic peoples who, according to ancient Chinese sources, inhabited the eastern Asian Steppe from the 3rd century BC to the late 1st century AD. Chinese sources report that Modu Chanyu, the supreme leader after 209 BC, founded the Xiongnu Empire.
Xirong
The Xirong together with the eastern Dongyi, northern Beidi, and southern Nanman were collectively called the "Sìyí" (). The "Liji" "Record of Rites" details ancient stereotypes about them.
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 term 狄鞮 "didi" ("ti-ti") is identified as: “("anc.") Interpreter of the Di, barbarians of the west.” Translated and adapted from the French.]
