The sinologist Edwin G. Pulleyblank describes how "Yi" usages semantically changed. "Their name furnished the primary Chinese term for 'barbarian' and is sometimes used in such a generalized sense as early as the Spring and Autumn period. At the same time, it continued to have a specific reference, denoting especially the Yi of the Huai River region, who constituted a recognized political entity. Paradoxically the Yi was considered the most 'civilized' of the non-Chinese peoples."
