Name

Its name Đạ Huoai (Daa-huoaai, "the stream of waiting") is related with the legend of Da Mbri, which means "river Mbri" or "hero Bri". After his death, Bri became a big river. In addition, Mdaa-guih (now Ma Đa Guôi town) means "a place of pause", which refers to where Bri was still waiting for his lover.
