Kongpo
Kongpo is a region in Gongbo'gyamda County, Nyingchi Prefecture. It is situated on the Nyang River, a northern tributary of the Yarlung Tsangpo River.
Kongpo was an area of southeastern Tibet in the premodern period. Tsagong was one of the holy places of Kongpo and still is. Thang Tong Gyalpo, a famous architect and yogi, founded Manmogang Monastery, where the original Samding Dorje Phagmo died. Nearby are the mines from which Thang Tong Gyalpo obtained the iron for some of his bridges.
Old Tsari is now part of the modern county of Lhuntse in the southeast of the Tibet Autonomous Region and including parts of neighboring areas of India, and New Tsari is located farther east.
