Bình Nguyên

Bình Nguyên lay in the mountainous country of the upper Lô River, where the valleys of Vị Xuyên open southward from Hà Giang. Its old name appears in records of the Lý and Trần periods; under the Lê it became Vị Xuyên. Forested hills and streams surround the cultivated land along the river, linking this northern frontier with Tuyên Quang farther downstream.
