Can I travel in Tibet by bus？

You can try on taking bus when you are this way: Lhasa -Golmud and Lhasa-shigatse .But don't take the bus to Tsedang ,the checkpoint through this way is very strict! And you'd better not take the bus to Dam, it's an adventure anyway! And the road to LinZhi are on the construction, so It is quite impossible to go there by bus!
