By road, the distance is 1,120 km (700 mi) via the southern route or 1,030 km (640 mi) via the northern route. It is at an altitude of 3,230 m (10,600 ft) at the confluence of the rivers Za Qu and Ngom Qu which form the Lancang River (Mekong).
At the turn of the 20th century it had a population of about 12,000, a quarter of whom were monks.

## Galden Jampaling Monastery

Chengguan was visited by Je Tsongkhapa in 1373 who suggested a monastery be built there. Galden Jampaling Monastery was constructed between 1436 and 1444 by a disciple of Tsongkhapa, Jansem Sherab Zangpo. It is also known as the Changbalin or Qiangbalin Si Monastery. At its height it contained five main temples and housed some 2,500 monks. It was destroyed in 1912 but the main hall (which was used as a prison) and two other buildings survived, and it was rebuilt in 1917 after the Tibetan army retook Chengguan. It now houses about 800 monks.
