The population of the Nùng is estimated to be more than 700,000, located in the provinces of Bac Giang, Bac Kan, Cao Bang, Lang Son, Thau Nguyen, and Tuyen Quang. The Nùng language is part of the Tai languages (written script developed around the 17th century). It is close to the Zhuang language.
The Nùng support themselves through agriculture, such as farming on terraced hillsides, tending rice paddies, and growing orchard products. They produce rice, maize, tangerines, persimmons and anise. They are also known for their handicrafts, making items from bamboo and rattan, as well as weaving. They engage in carpentry and iron forging also.
When drinking alcohol, partakers cross hands and drink from the opposite glass to demonstrate trust. Fairy tales, folk music, and adherence to tradition and ethnic identity are strong characteristics of Nùng people.
