In the Han Dynasty, what did the Huns mean by "Dead Qilian Mountain"?

The death of my Qilian Mountain made my six animals unhappy. Death makes my woman colorless. Qilian Mountain is the name of the mountain. Qilian Mountain is a marginal mountain system in the northeast of Qinghai-Tibet Plateau.

Without Rouge Mountain, it is difficult for us to graze and live in poverty, and women have nothing to see because they live in poverty. The loss of Qilian Mountain deprived us of good pasture and livestock could not reproduce. How sad we are.

A famous soldier and strategist in the Western Han Dynasty (before 140- before 1 17). Pingyang County, Hedong, is a native (now southwest of Linfen, Shanxi). As a servant of Wei Ruyun Zifu's sister, he was regarded as an excellent rider and shooter when he was young.

In the sixth year of Yuan Shuo (before 123), Huo Qubing was appointed as the captain of whoring Yao by Emperor Wu of the Han Dynasty. With Wei Qing, he attacked Xiongnu in the desert south of the Mongolian Plateau (south of today's Great Desert), killing 2028 people with 800 people, and was awarded the title of champion.

In the second year of Yuanshou (formerly 12 1), he was named an ancient general. In the spring and summer, he led troops to attack the Xiongnu Department which occupied Hexi (now Hexi Corridor and Huangshui River Basin), killing and injuring more than 40,000 people.

In the autumn of the same year, he was ordered to meet the evil king of Xiongnu who led the troops to surrender to Han. At the critical moment when some troops surrendered to the Han Dynasty, Huo Qubing personally rushed into the Xiongnu Camp and confronted the evil king of Xiongnu, killing more than 8,000 people who refused to surrender, thus stabilizing the situation. The evil king of Xiongnu was able to lead more than 40,000 people to the Han Dynasty. From then on, the Han Dynasty took control of Hexi area and opened up the road to the western regions.
