Did Emperor Wu of the Han Dynasty recover the Hetao area?

The pro-Qin policy in the early Han dynasty was carried out under the situation that Hungary was strong and China was weak. Although the Huns married Han Fei and gave a lot of property, they did not completely stop invading the border counties of the Western Han Dynasty. When Emperor Wu of the Han Dynasty ascended the throne, after more than 60 years of recuperation, the Western Han Dynasty enjoyed a prosperous economy and strong national strength. He decided to fight back against the Huns and started the war against the Huns in 133 BC (the second year of Yuanguang). BC 127 (the second year of Yuanshuo), the Xiongnu 50,000 rode south to attack and killed the western Liaoning satrap. Emperor Wu of the Han Dynasty sent general Wei Qing to attack from the cloud (now Inner Mongolia and Linger) at a rate of 30,000, recovered the Hetao area, set up Shuofang County (now north of Hangjinqi in Inner Mongolia), and enriched 6,543,800 immigrants, thus relieving the threat of Xiongnu to Chang 'an. BC 12 1 year (the second year of Yuanshou), he ordered Huo Qubing, a general, to lead tens of thousands of troops from Longxi, cross Yanqi Mountain, and travel thousands of miles to the Xiongnu territory. In the summer of the same year, Huo Qubing attacked from Beidi (northwest of Qingyang, Gansu), crossed Juyanhai (north of Ejina Banner, Inner Mongolia) and went south to Qilian Mountain. Hunhun Evil King killed Xiutu King and led more than 40,000 people to surrender to Han. The Han Dynasty captured the Hexi area where the two kings lived, and established Jiuquan, Wuwei (now the northeast of Minqin, Gansu), Zhangye and Dunhuang counties, which cut off the contact between Xiongnu and Qiang people and provided an important channel for the communication between Han and the western regions. Later, Xiongnu Khan withdrew his main force to Mobei. The Huns lost the Hexi Corridor with abundant water plants, which caused huge economic losses. They sang sadly: "losing Qilian mountain makes my six animals unhappy;" Losing my mountain makes my wife colorless. " ("Historical Records and Biography of Xiongnu" quoted "Old Things in Hexi")
