The Hengduan Mountains are located at the junction of Tibet, Yunnan and Sichuan provinces and extend north and south. The high-risk Xiongjun is shaped like a barrier with a total area of about 550,000 square kilometers. The ideal laboratory transverse mountains are west- Mount Gaoligong - Mount Snow - An Nu, Quiet Mountain - Snowy Mountains, etc. Their average altitude of 3000 to 4000 km, some as high as 5 or 6 km, the highest peak of Mount Gongga 7590 meters above sea level. The relative altitude of these north-south mountains is about 2,500 meters. In the valleys, the Nu River, the Lancang River and the Jinsha River (“Sanjiang”) growl and rapids rapids. The mountain valleys cut off traffic in the east-west direction.
