Ulungu Lake, also known as Buluntohai, Dahaizi and Fuhai, is located in Fuhai County, Altay Prefecture, Xinjiang, China. The color of the lake water amazed me, as green as emerald, and it is known as the farthest sea from the sea. After leaving Ulungu Lake, we went to Kelan Grand Canyon, which is also quiet and pleasant. The Kelan River, the mother river of Altay City, flows out from here.
