The Shangnan Sky Road in Rangtang County, Aba Tibetan and Qiang Autonomous Prefecture, Sichuan Province has a total length of about 34 kilometers and a total investment of about 50 million yuan.

After its successful expansion and reconstruction in 2017, the “last mile” for herdsmen and nomads's travelling problem was solved, which directly benefited more than 2,000 herdsmen in Wukeji and Asma villages along the route.

The winding road itself has become a “beautiful business card” for developing tourism in Rangtang County.
