How much is the tour to South Korea in Xining?

Not counting the fare, I went to Tibet last year and stayed in Tibet for ten days, about 4.5k. I stayed in Lhasa for four or five days and went to Linzhi, Mount Everest, Namco and other places. If you buy a ticket, buy a train ticket in advance. Hard seat? 2 17, hard sleeper? 5 1 1, soft sleeper? It won't cost much. I hope I can help you.
