The first Brau came to Vietnam about a century ago. They live mainly in southern Laos and northeastern Cambodia. At present, most Brau communities are still living in the basins of Xe Xan (Xa ma cang) and Nam Khoong (Mekong) rivers. The Brau are pround of their traditions, which they recall in such legends as Un cha dac lep (rising blaze, rising water), about how great floods were weathered by the Brau people.
