KINGDOM OF KOYING
About the kingdom of Koying, 3d century
Google translation
According to the Chinese records, the oldest kingdom in Eastern Sumatra was not the now-famous Sriwijaya, which rose to power on the Musi River in the seventh century. It had some predecessors in the region which dated back the early centuries of the first millennium. Bearing names such as Kantoli, Poli, Holotan and Ko-ying, these early polities were long known to the world only by the scant Chinese sources.
The most powerful of these kingdoms is thought to have been Ko-ying, whose heyday may have been between the second and sixth centuries.
Archaeological research from Sumatra over the pat quarter century suggests that it was probably located on the eastern seaboard of Sumatra after all, downstream from the current location of the city of Palembang.
