Mnong people

The Mnong or Munong (Vietnamese: "người Mơ-nông") are an ethnic group from Vietnam (127,334 in 2019) and Cambodia.
History.
Mnong can be subdivided into three groups :
A number of Mnong live in the eastern Cambodian province of Mondulkiri where they are known as Bunong (alternatively spelled Phnong, Punong, or Pnong). The Mnong people have been widely persecuted and discriminated against because they were thought to have aided North Vietnam in its civil war against South Vietnam and the United States of America during the Vietnam War. They were brutally massacred and have been neglected for decades for their unproven "Engagement" with the Viet Cong.
Culture.
Every group speaks a variant of the Mnong language, which along with Koho language, is in the South Bhanaric group of the Mon–Khmer family.
Epics (Mnong language: Ot N'rong- Ot: telling by singing the poem, N'rong: old story) take an important part in Mnong people's life. Many of these epics, such as Ghu sok bon Tiăng, are quite long.
