In the old days, "The high mountain and thick forest" named Buon Ma Thuot was considered Ede's sanctuary. People of this land of red soil worshiped the dirt they walked on. The language they used was mainly Rhadé. "Buon" meant village, "Ma" meant father, and "Thuot" was the name of the chief's son, who led his people fought against Khmer and Ai Lao (Laotian) armies when they invaded their land.
Because the soil was so important to them, they named every place on their land after it, such as Cu M'Gar (a reverse mountain), river k'rong Ana, krong k'No, and a reverse river Serepok are water supplies for coffee plants.
