Why are there so many records of Tianshan Mountain in history? This shows the historical value of Tianshan Mountain.

Qilian Mountain Range is located in the northeast of Qinghai Province in China and the west of Gansu Province, and it is one of the main mountain ranges in China. It consists of many parallel mountains and wide valleys running northwest-southeast. Because it is located on the south side of Hexi Corridor, it is also called Nanshan. It is 800 kilometers long from east to west, 200-400 kilometers wide from north to south and 4000-6000 meters above sea level. * * There are 3,306 glaciers, covering an area of about 2,062 square kilometers.

The western end is connected with Altun Mountain at Dangjin Mountain Pass. East to the Yellow River Basin, connected with Qinling Mountains and Liupanshan Mountains. It is nearly 1000 km long. It belongs to folded fault block mountain. The widest place is between Jiuquan City and Qaidam Basin, reaching 300 kilometers.

The mountains extend from northwest to southeast, including Daxue Mountain, Tolai Mountain, Tolai Mountain, Maye Mountain, Shule Mountain, Danghe Mountain, TourKenda Banshan Mountain, Qaidam Mountain and Zongwu Mountain.

"Qilian" is a Hun language. Huns call heaven "Qilian" and Qilian Mountain means "Tianshan Mountain". Because it is located in the south of Hexi Corridor, it is also called Nanshan in history, and there are also names such as Snow Mountain and Baishan.

Qilian Mountain in a broad sense is the general name of the border mountainous areas in western Gansu Province and northeastern Qinghai Province. In Qinghai, it is located in the northern margin of Qaidam basin, Chaka-Shazhuyu basin, north of the main stream of the Yellow River, north to the provincial boundary, west to Jinshankou and east to the Qinghai provincial boundary. Geographical coordinates: 94 E10'-10304', 35 50'-39 N19'. In a narrow sense, Qilian Mountain refers to the northernmost mountain of Qilian Mountain.
