Kurung Kumey district
Kurung Kumey district (Pron:/kʊˈɹʌŋ kʊˈmi/) is one of the 26 districts of the northeastern Indian state of Arunachal Pradesh, with its district headquarters in Koloriang. Origin of name
The name of this district is derived from the Kurung and the Kumey, the two principal rivers which flow through it. According to the myth the Kurung and the Kumey rivers were two sisters; during the age of marriage Kurung eloped without prior permission from her parents and Kumey got married according to her parents' wishes. Therefore, the Kurung flows with a violent roar and ashy colour because her parents shout and throw ashes after her, while the Kumey flows silently and clearly with pleasure from her parents. So people Accepted River was more beautiful than the Kurung River and followed the discipline of their parents. History
