How much does it cost to travel to Tibet?

See how you play. My colleague went there for more than half a month before, and a * * cost about 3 thousand. From Beijing to Lhasa by train, the hard seat is less than 1000. After that, going to other places from Lhasa is basically a ride. These two girls are good at hitchhiking, and many people ask them where they are going. There is not much money for food and accommodation, mainly transportation. I went halfway around Tibet and returned to Lhasa, and then took the train back to Beijing.
