Customs and habits
The Co believes that all things have souls, and they worship the souls of rice grains. In former days, the Co lived in long houses built on stilts. Recently, the Co has built shorter houses that are level with the ground. The village chief is chosen on the basis of knowledge, experience in production, behavior, and the trust of villagers. In the past, no Co lineage had an individual name; they all took the family name of Dinh. Now, they have taken the family name of Ho, after President Ho Chi Minh.
The Co language belongs to the Mon-Khmer Group. The Co like to sing, dance, beat drums, and gongs. Folksongs such as the Xru, Klu and Agioi are very popular.
Men leave their upper torsos naked and cover their lower torsos with loincloths. Women wear a skirt, bra and shirt with short sleeves. Women often tie colourful beaded strings around their waists. In winter, they cover themselves with blankets.
The Co lives mainly from slash-and-burn agriculture. They grow rice, maize, cassava, cinnamon, and other plants.
