布立吞語, also known as Buli Tunu, is a language spoken by the Buli people in parts of China. It belongs to the Tibeto-Burman language family and is primarily used in daily communication among the community. The language features unique phonetic and grammatical structures, making it distinct from other regional languages. Efforts are being made to preserve and promote Buli Tunu as younger generations increasingly adopt more dominant languages in the area.
