I did not know how far it was between Tsonyi County and NagquTown until I checked the map: a whopping 520 kilometers! Located in the northwestern area of the northern Tibet and inside the Changtang National Nature Reserve, Tsonyi is the county standing upon the highest plateau of the world. The place was once known as "No Man's Land" due to it as well as Hoh Xil to the north being so unfrequently visited?
