The
Nùng (
pronounced as noong ]) are an ethnic minority in Vietnam whose language belongs to
the Central Tai branch of
the Tai-Kadai language family. The Nùng sometimes call themselves as Tho (
Vietnamese: Thổ, a shared name between
the Tày and
the Cuối, literally means
Natives). The term Thai Nung is also used to distinguish them with the Chinese Nùng who were the majority ethnic group in the Nung Autonomous Territory of Hai Ninh (1947-1954). The Nùng's ethnic name is often mingled with the Tày as Tày-Nùng.
