This is the origin of three of the most famous rivers in China:the Yangtze River,River Lancangjiang and Nujiang. Here,the attempt by Genghis Khan to advance into the Indian subcontinent was thwarted and crushed. This is the gateway from Qinghai Province to Tibet and the natural boundary between the administrative regions of Qinghai and Tibet. This is also the highest point on four highways into Tibet:Sichuan-Tibet,Qinghai-Tibet,Yunnan-Tibet, and Xinjiang-Tibet,as well as the highest point on the highest railway in the world. It was more than 50 years ago that the construction of the Qinghai-Tibet Highway(China National Highway 109)was begun.The Qinghai-Tibet Railway was opened in 2006.This was the most challenging section during the constructions(due to its high elevation). Between 1991 and 2009,I drove through Tanggula four times.
This is the origin of three of the most famous rivers in China： the Yangtze River, River Laneangjiang and Nujiang.
