Located in the north bank of the Yarlung Zangbo River's mid-stream, the relocation site is a key place to improve the production and living environments of the Tibetans in extremely high altitude areas with harsh natural conditions.

By December 2019, 3,364 people from Nagchu City have settled here. The living conditions of the relocated people have been greatly improved after moving from the northern Tibetan plateau with an average elevation of about 5,000 meters to a lower southern Tibetan river valley.
