In early November, going to Nyingchi, how is the autumn scenery in Lurang? It's quite nice or not necessary to go there specially? Now I'm hesitating between staying in Suosong village for 2 nights or spending 1 night in Suosong and 1 night in Lurang.

The location in Suosong Village for viewing Namjag巴wa Peak is excellent, but one night is enough; not going to Lurang would be hard to explain.
The Solmon Village is an excellent location to view the Namjag巴瓦 Peak, but staying for one night is enough; not visiting Lurang would be difficult to explain.
