The average mountain range of Qilian Mountain is between 4,000 meters and 5,000 meters above sea level. The long and wide glacier landscape formed by snow in the mountains is beautiful and spectacular. There is a grassland under Qilian Mountain that is the most beautiful water grass, that is, summer Tala (also called Huangcheng Beach, Huangcheng Beach, Dacao Beach). It was once the pastureland of the Hunnu king, the pastureland of the Hui people, and the pastureland of the Mongolian king Kuo Duan Khan in the Yuan Dynasty. Summer Tara is a grassland with clear seasons and smooth wind and rain. The Qing people Liang Fen's famous geographical book "Qin Bian Jilu" said: "Its grass is nothing but the mainland." The author considers this place to be the mainland because nomads and farmers were competing for the area at the time. The Tibetan epic "Gesar" said that this grassland is "Golden Lotus Grassland". And the people of Yuanbaoer and Mongolia call it "summer tala", meaning "golden pasture". fold
