Emerald Lake, also known as Water Cui Lake, the Qinghai-Tibet Plateau was once part of the ocean. After a long period of crustal movement, this ground was lifted into the world's largest plateau, resulting in the sea left in some low-lying areas to form many salt lakes and ponds, and the Emerald Lake is also one of them. This about 6 square kilometers of "emerald lake" is the former Dachaidan chemical factory salt lake mining team mining area, Ikechaidam Lake is also known as Dachaidan Lake, for salt lake, lake rich in boron, lithium, salt, potash fertilizer, mango nitro, etc. This size is different, the form is different, The high concentration of salt water in the salt pool is called "breed" in the local area. It is a mining pit formed by years of salt lake mining. Due to the different concentrations of minerals contained, it also forms a colorful scene, especially the calm time. Like a mirror scattered around, reflecting the blue sky and white clouds, the snow peak of Chaidamu Mountain, in the midst of it, watching the shadow at the foot, the feeling at this moment, only in the body can be deeply felt.
