Zheduo Mountain is a vein of snowy mountains. The highest peak of Zheduo Mountain is 4962 meters above sea level, and the altitude of Lukou is 4298 meters. The altitude gap with Kangding City is 1800 meters. It is the first alpine port on the Sichuan-Tibet line that needs to be crossed, so it is called "Kangba First Pass". Zeduoshan is both the watershed of Dadu River and Yaqi River basin, and the boundary of Han-Tibet culture. After crossing the Zeduoshan, it officially entered the Kangba Tibetan area. The winding road of the mountains is indeed nine curves and eighteen bends, and the winding back and forth is like the word "multi", turning a bend, and a bend, no wonder the locals have a sentence: "the scary Erlang Mountain, the dead people folded mountains".
