Unique "watermills" of Tuyen Quang
TOQ - The Tay people in Tan An Commune (in Chiem Hoa District, Tuyen Quang Province) always compare the cọn, known as waterwheels, to a "mill" working diligently day and night to bring water to upland fields and to their homes. The creaking of the cọn combined with the murmurs of water create the ordinary sounds of the mountains.
