Wutun is a settlement in Tongren County, in the eastern part of Qinghai province, China. It is known primarily as the home of the Wutun language, also called Ngandehua, which is spoken by about 4,000 people. Wutun speakers live in two villages within the county.
The Wutun language is a Mandarin–Amdo–Bonan creole, a mixed language that developed from contact among Mandarin, Amdo Tibetan, and Bonan elements. Most of its speakers are classified by the Chinese government as Monguor (Tu), a designation that reflects official ethnic categorization rather than the language's mixed origins.
Wutun's significance lies chiefly in this linguistic heritage: it is one of the few documented cases of a creole language in the region, and its small speaker population makes it a subject of interest for the study of language contact and creolization in western China.
