Xiongnu has always been the enemy of the Central Plains during the Warring States Period. Li Mu, a famous soldier of Zhao during the Warring States Period, resisted the invasion of Xiongnu at the border all the year round. After Qin Shihuang unified the whole country, he also sent Meng Tian, a famous soldier, to guard the border with 300,000 troops, showing the harm of Xiongnu to the Central Plains dynasty. After the establishment of the Han Dynasty by Emperor Gaozu Liu Bang, the Huns plundered and abused the Han border many times, which led to the depression of the people's livelihood in the Han Dynasty. Although Liu Bang also attacked the Huns, he ended in failure. In addition, the national strength of the Han Dynasty was not strong.
Wolves live in Xushan in the hinterland of Xiongnu.
During the period of Emperor Wudi, the Han Dynasty fought against the Huns on a large scale, using cavalry to fight against tarquin, defeated the Xiongnu army many times, and captured the kings of several Xiongnu tribes. Among them, Huo Qubing hit the hinterland of Xiongnu, and the wolf lived in Xushan. Although meditation is a power that the emperor can only execute, the wolf lives in Xushan, which is a sacred place for Xiongnu to worship heaven and is in the hinterland of Xiongnu territory. Therefore, it is impossible for Liu Che, the Emperor of the Han Dynasty, to go in person. Moreover, as a Han Chinese, he was already out of the evil spirit of the Emperor of the Han Dynasty, so even Huo Qubing was happy to do it for him.
Huo Qubing was deeply loved by Emperor Wu of Han Dynasty.
Huo Qubing is a relative of General Wei Qing and Wei Ruyun's son-in-law, so he has lived in the palace since he was a child. Emperor Wu of the Han Dynasty grew up watching Huo Qubing, while Huo Qubing liked the military since he was a child, and he also had a very high military talent. So Emperor Wu of the Han Dynasty had high hopes for Huo Qubing, so he asked Huo Qubing to lead the troops to the Huns when he was 18 years old. Huo Qubing was indeed a once-in-a-century generalship and made great contributions, while Emperor Wu of the Han Dynasty paid more attention to it and even defected to Huo.
