The Chaerhan Salt Lake is one of the largest natural salt lakes in the world. The Qaidam Basin between Kunlun Mountain and Qilian Mountain is known as the treasure bowl of the Qinghai-Tibet Plateau. The heart of the Qaidam Basin is the famous Chaer Khan. Its rich and surprising salt mine resources and the 32-kilometer singular Banzhang Salt Bridge have made its name resound for more than half a century. Most people only know the Chaka Salt Lake, but the Chaer Khan Salt Lake is larger and less well known. "Chaer Khan" is Mongolian, meaning "Yanze". Salt Lake is located in the Gobi Desert, where the climate is hot and dry, the sunshine is long, and the evaporation of water is much higher than the precipitation. Due to the long-term wind and sun, a high concentration of brine was formed in the lake, which gradually crystallized into salt particles. The lake panel was formed into a thick salt cover, which was extremely hard. Incredibly, there is a 32-kilometer long road and railway passing through the salt lake. It is a wanzhang salt bridge floating on the brine. The road and railway are a section of Golmud to Dunhuang Highway and Qingzang. A section of the railway. Unlike Chaerhan Salt Lake and Chaka Salt Lake, it is really a "lake." In fact, this is not a scenic spot, and the road to come in has also taken some effort. This is a salt lake where you can see the rushing lake. The shore is full of salt and alkali, a thick layer. When you step on it, it will seep slightly in the water. It feels like walking in the snow.
