Quỳ Châu
Quỳ Châu lies in the mountainous western country of Nghệ An, where river valleys cut through the highlands between the Vietnamese coast and Laos. Tai communities have long formed an important part of its population, with different groups preserving traditions of migration and settlement. Their villages occupied a landscape of forests and cultivated valleys, linked to other upland communities across the mountains of the upper Cả basin.
