There are Tian Mountains in Gansu and Qinghai - Is it True?

Qilian Mountains (located in the northeastern part of Qinghai Province and the western part of Gansu Province) generally refers to the Qilian Mountains range.

The Qilian Mountains range is located in the northeastern part of Qinghai Province and the western part of Gansu Province, and is one of the main mountain ranges within China.

Composed of multiple north-south and east-west oriented parallel mountain ranges and wide valleys. It stretches 800 kilometers from east to west and 200-400 kilometers from north to south, with an altitude of 4000-6000 meters, and has 3306 glaciers with an area of approximately 2062 square kilometers.

Originally, 'Qilian' referred to the southernmost mountain ridge along the Hexi Corridor (southwestern extremity of the Hexi Corridor, with an altitude of 5547 meters), or the narrow 'Qilian Mountains'.

'Qilian' derives from the Hunnic language, where 'Tian' (sky) was called 'Qilian', and 'Qilian Mountains' meant 'Tian Shan' (Celestial Mountains).

Historically, it was also known as 'Nan Shan' (South Mountain) due to its location south of the Hexi Corridor, along with names such as 'Snow Mountain' and 'White Mountain'. During the early years of the Western Han Dynasty, when Du Ju Bing conquered the Huns, he said, 'Lose Qilian Mountains, and I will not have descendants; lose Yanzi Mountains, and my brides will have no color.' This 'Qilian Mountains' referred to the 'Qilian Mountains' in Hunnic folk songs.

It now generally refers to a series of mountain ranges in Gansu and Qinghai that are linked geologically and morphologically.
