Na Su village is located in Muong Cha commune, 120km from the center of Dien Bien Phu ward, on Route 4H leading to A Pa Chai, the westernmost point of Vietnam.

Na Su means "purchased rice field" in the Thai language. Previously, Na Su was called "Na Pien" or "Na Kheo Pieng" because this rice field was first cleared and cultivated by the Khmu people who settled here. At that time, the Khmu people had a custom of filing their teeth to make them even, so "Na Pieng" or "Na Kheo Pieng" was understood as "the field of people with even teeth" (in Thai, "Na" means field, "Kheo" means tooth, and "Pieng" means even). After they left, the Thai people bought the field and called it "Na Su" or "Na Su". The village has rich forest resources and diverse vegetation. There are natural forests interspersed with man-made forests, mainly acacia and bamboo. In addition, Na Su village also has mineral resources, such as common building stone.
