Nándǎn
Nandan was a district in the mountain country north of Yingjiang, west of the Gaoligong range. Its old seat lay at Mengnong, among valleys watered by tributaries of the Daying River. The wider region was home to Tai communities and hereditary chiefs whose territories shifted during the struggles between Luchuan and the Ming. Forested slopes enclose the small basins, while rivers lead south and west toward the lands beyond the mountains.
