The ground area of the project is far away, the development of local economic life is relatively lagged, and the living standard of herdsmen is low. The relevant departments of the military committee logistics support department show that through the construction of infrastructures such as traffic, electric power and the like, the development of social economy and improvement of the living standard of people in remote national regions can be effectively driven, the national unity and the military and civilian unity are improved, the social stability is promoted, the national unity is maintained, and the smooth implementation of the national precise poverty-relieving strategy is facilitated.
