Speaking of the Xiongnu race, everyone is more familiar with it, because in Chinese history, the Xiongnu have also appeared many times, and have become the fierce enemies of many Central Plains dynasties. Moreover, some dynasties were exhausted by the Huns. During the Han Dynasty, the Xiongnu had harassed the Han Dynasty, and the Han Dynasty could be said to be a relatively powerful country among the feudal dynasties, and it inherited the political system of the Qin Dynasty and obtained advanced military equipment. But even so, the two countries have been entangled for more than 100 years.
But you know what? In the Spring and Autumn Warring States period, there is a country it immediately beat the Xiongnu to the ground, this country is the Zhao state established in 403 BC, the Zhao state in the Spring and Autumn period is not prominent, just an ordinary one of the princely states, in the Warring States period became one of the seven xiong, the zhao state monarch is the surname of Zhao, they are the descendants of a famous subject during the Shang Dynasty, this family they also attach more importance to military development, King Zhao Wuling established the first cavalry in Chinese history, unfortunately with the development of the times, The State of Zhao also gradually declined, and in 222 BC, it was defeated by the Qin Dynasty and disappeared into history.
At that time, the territory of the Zhao state was mainly in the northeast region, which bordered the Eastern Hu and Heyan states. This has some feelings of internal and external troubles, so in 425 BC he moved the capital, after moving the capital still felt that it was not OK, and in 386 BC, he moved the capital to Handan, Hebei. After settling there for more than a decade, he still felt uncomfortable, and Zhao Chenghou established Xing as the capital of Xin in 372 BC.
At that time, the military strength of the Zhao State was relatively strong, they were mainly infantry and chariots, and the knights were also superb. Unfortunately, they are mainly in the Central Plains, their officials wear loose battle robes, compared to the tights worn by ethnic minorities are more suitable for combat, so when the Zhao state and the cavalry of the ethnic minorities fight, they are in a disadvantageous position, and the Zhao monarch Wuling King does not want this, so he immediately implemented the "Hu costume riding shooting", after his implementation, finally trained a group of elite cavalry with strong combat ability. But even so, the Xiongnu and the Zhao State were entangled for more than ten years, until then the Zhao State appeared a general to stop.
This general, Named Li Mu, died in 229 BC, he was the son of a prince and noble family, so he received more advanced knowledge from an early age, and when he was in charge of the army, he summarized some of the methods of the army against the Xiongnu at that time. The eight-character policy was carried out to firmly clear the field and refuse not to go to war.
At the same time, he also strengthened the training of soldiers to strengthen their combat ability against the Xiongnu soldiers, when in 265 BC, Li Mu saw that there were some bad conditions in the Xiongnu territory at that time, so Li Mu released cattle and sheep that spread over the mountains to let the Xiongnu throw themselves into the net, through this means, the Xiongnu soldiers were annihilated by the Zhao State more than 100,000. Since then, these Xiongnu countries have not dared to invade the Zhao state, and in 221 BC, after Qin Shi Huang unified the six kingdoms by force and established the first great unified dynasty in China's history, he began to expel the Xiongnu, and the Xiongnu feared Qin Shi Huang's force and began to withdraw 700 miles away.
