Chepang is the commonly used name given to an indigenous ethnic group living in central and southern Nepal. The language is also known as Chepang but is called Chyo-bang by the people themselves. Some Bahun Chettri castes call these people the "Praja" meaning "political subjects". The people speak 3 different dialects of this Tibeto-Burman language that is closely related to Raute and Raji, two undocumented languages spoken in western Nepal. Chepang language is one of the few languages which uses a duodecimal (base 12) counting system rather than the decimal (base 10). Chepang traditionally practised some slash-and-burn agriculture, or simple hoe-based horticulture along with mostly hunting and gathering from the forests. Since being resettled in southern Nepal and impinged upon by Nepali speaking groups, Chepang have begun plow-based agriculture. Chepang men and women are basically egalitarian and no social ranking exists as it does in caste Nepalese society.
