Dachaidan, Mongolian called Ike Chai Damu, meaning Great Salt Lake, is the North Gate of the Qaidam Basin. It is located in the northwestern part of Qinghai Province, on the northern edge of the Qaidam Basin. It is a directly administered county of Haixi Mongolian Tibetan Autonomous Prefecture. Administrative level. When I arrived at Emerald Lake, I suddenly realized the name of it - it was really emerald. This is an open-air attraction, without a gate, more like a masterpiece of nature, and even the road is pitted. It is said that the real scenery should be on the road, not being "captive". It is not as crowded as the Chaka Salt Lake, and the place is spacious, even if there are some visitors, it does not hinder the photographing. Because the lake is particularly large, when we take pictures, the little friends are on the other side, and I am on the other side. The photos taken in this way are small and large, and they can hardly see the face. Therefore, regardless of the low value of the face value, they can shoot large films in minutes. When we went, it was sunny, but because the local dust was not small, the sky was like a mist. However, this does not prevent us from admiring the beauty of the Emerald Lake. It is like a mirror-like lake reflecting the blue sky and white clouds and the snowy peaks, just like being in a fairyland. The most important thing is that Emerald Lake is free of tickets!
