A Yunnan civil-affairs account begins with an important distinction: Kunming was recorded as the name of an ancient people before it became a place-name in the Dianchi area. The page cites historical texts that place groups known as Xi and Kunming across a broad region between what are now western Yunnan and the Erhai area. These records describe mobile communities; they are not a straightforward map of present-day ethnic identities.
Historical names travel. A label used by chroniclers may cover changing groups and territories, and later readers may interpret it differently. For that reason, the ancient ethnonym should not be treated as a direct synonym for any single community living in Yunnan today. The civil-affairs account itself presents the evidence through named historical works and distinguishes it from later theories about the word.
