Li Guang and Gongsun Ao were defeated by the enemy and later demoted to common people. Gongsun He walked a long way, but did not meet the Huns. There is neither merit nor fault. Only Wei Qing fought from Shanggu, killed 700 enemies, and pursued them all the way to Longcheng.

The Battle of Shanggu was the Han Dynasty's first victory over the Xiongnu, and it absorbed the humiliation of Han Gaozu Bai Deng. Emperor Wu of the Han Dynasty was overjoyed and named Wei Zifu the queen and Wei Qing as Guannei Hou. In 124 BC, the Hexi War broke out. Wei Qing commanded more than 100,000 troops to surround King Youxian of the Xiongnu at night, and then launched an attack. At this time, King Youxian was caught off guard. He was drinking and having fun with his beautiful concubine. Seeing the sudden arrival of the Han Dynasty army, they hurriedly broke through and escaped.

Wei Qing captured more than ten people from Xiao Wang, more than 15,000 men and women, and hundreds of thousands of livestock. Emperor Wu of the Han Dynasty was very happy to know the result.

In the spring of 121 BC, Emperor Wu of the Han Dynasty made Wei Qing's nephew Huo Qubing a hussar general, and was ordered to lead 10,000 cavalry to capture the Hexi Corridor. Huo Qubing set out from Longxi , passed through Yanzhi Mountain , and met the Huns army. After a fierce battle, the Huns army was defeated and fled north. Huo Qubing pursued the enemy for six days. The soldiers killed King Zhelan and King Luhu of the Xiongnu, and captured the son of King Hunxie, Xiangguo, and captain . At the same time, they captured the golden man used by the Huns to worship heaven. In this battle, more than 8,900 Huns soldiers were killed.

In the summer of the same year, Huo Qubing led his army across the Xiaoyueshi Zhangye and attacked the Qilian Mountains . He captured five kings, 59 princes and the mother of Shanyu , and killed more than 30,000 people. These two battles were unprecedented victories for the Han Dynasty. Huo Qubing was only 20 years old at the time. From then on, the Huns were afraid of Huo Qubing. They were extremely compassionate. "If I lose the Qilian Mountains, my animals will not be able to live; if I lose the Yanzhi Mountain, my married woman will have no color." Once, Emperor Wu of the Han Dynasty built a mansion for Wei Qing, but he politely refused. He said, "The Huns are not destroyed, so why should we take care of our family?" Emperor Wu of the Han Dynasty appreciated his noble quality of "putting the country first, then the family" and trusted him even more from then on.

Wei Qing set off from Dingxiang County . His troops divided into two lines. The main force was commanded by himself, and the Eastern Route Army was led by Flying General Li Guang. Wei Qing crossed the desert and encountered the Xiongnu Chanyu army. He surrounded the army with chariots and sent 5,000 elite soldiers to fight the Huns, but suddenly there was a wind and sand all over the sky. Wei Qing divided the main force into two wings and attacked the enemy from both sides. Shanyu saw that the situation was not good, so he broke out with several hundred men and horses. Wei Qing led his troops in pursuit, but failed to catch up with Shan Yu and only burned Shan Yu's food and grass. Flying General Li lost his way in this war and did not participate, which greatly affected the battle.

Huo Qubing led his army from daijun and traveled more than two thousand miles. Finally, they came to Xincheng and started a fierce battle with King Zuo Xian. King Zuoxian was defeated and fled with only a few people, losing 70,000 troops.Huo Qubing pursued him to Langjuxu Mountain, climbed the mountain to worship in the direction of the Central Plains, and erected a victory monument on the mountain, which is called "Sealing Langjuxu".
