small unit of Tai-Khamyang people migrated from "Möng Mao Lung dynasty" (A.d-764-A.d-1252) in present-day Yunan Province of China and settled near Kopdup river in Upper Myanmar. It is said that the regions of Upper Myanmar geographically have full of resources. The Kopdub river flows through this region and has plenty of golds in the form of sand. The Tai-Khamyangs resided for a long period in this area lying on the Kopdub river. So literally they were known by the name "Khamyang" (Kham- Gold & Yang- To have) or "the people having gold" According to Ahom chronicles, prince Sukhapha and his followers were attacked by the Nagas at Khamjang on their way over Patkai. After his crossing over the Patkai, Khamyangs were driven away to take refuge in Assam under the oppressions of Siukhanpha. It is that early settlement of the section of Noras who was subsequently known by that name. The Tai Khamyangs, in the Patkai, got divided into two groups namely the Maan Nam or Pani Nora (Low Land Nora) and Maan Loi or Dum Nora (Upper land Nora). This settlement lies near the great lake "The Lake Of No Return" (Nong Kheo Lok Yang). In the mid-eighteenth century, due to the criticism surrounding for the presence of a couple of Cobras in the lake and problems faced from the Kachins, the Tai-Khamyangs crossed over the Patkai hill and settled in a fertile valley of Arunachal Pradesh. It is said that they constructed a pagoda which is still present near the no return lake. In the later period, they maintained good relationships with the Tai-Khamtis and established villages in Tengapani area. During the rule of Ahom king Gaurinath Singha, they immigrants to Jorhat district of Assam. With regard to their earlier migration to Assam, it may be noted that some Noras had accompanied Swargadeo Sukhapha and later on their separate identities were merged with the name Khamyang. History bears testimony to the fact that in 1524 Swargadeo Chukungmong married the daughter of the Nora Raja and Nora Raja equally was honored with a Khamyang damsel. It is quite probable that some Noras might have accompanied the princess in 1576. Swargadeo Chukhamfa also married one Nora princess. The princess was accompanied by a Nora prince, a priest, and 1000 Nora people. Culture Festivals & Events Poi-Sangken (Water Festival) used to be celebrated generally from 14th of April to 16th of
