Other comments: Bugan has a decimal numeral system. Bugan, Bogan, Pakan, or Bugeng (布甘语, 布干语, or 布赓语) is an Austroasiatic language. The existence of the Bugan language was not known by the rest of world until recently. There are about 3000 speakers, mostly in some villages in southern Guangnan (广南) and northern Xichou (西畴), Yunnan Province, China. Bugan is an analytic language, and word order and auxiliary words have important functions in the grammar.

According to Li Jinfang (1996), the Bugan-speaking population is distributed in seven villages across southern Guangnan (广南) and northern Xichou (西畴), Yunnan Province, China. As the language is highly uniform, it is not divided into any dialects.
