阿瓦王朝
The river rises on the Irrawaddy-Salween watershed, not far from the latter river, and flows westwards through northern Shan Plateau of eastern Burma where it is known as Namtu River, and eventually into the Ayeyarwady at Amarapura. The old capital of the Ava Kingdom was built between its two branches, Myittha River which it gives off to the west and the eastern stream which retains the name Myitnge before it enters the Irrawaddy.
