The Dong Nai culture (proto Oc Eo culture) in the South is the common name given to archaeological sites of the Metal Age located in the lower basin of the Dong Nai River. Iron tools and weapons of different types were found mostly in burial jars at Dong Nai archaeological sites. The Dong Nai people lived mostly in stilt-houses and they were good at iron metallurgy, making jewelry and pottery. In particular, their jewelry made of glass, gemstones and gold reflect the development of economy, culture and traditional custom, as well as cultural exchanges with surrounding cultures of the Dong Nai people.
