In 202 BC, Liu Bang, the emperor of the Han Dynasty, had just ended the war, and in order to ensure the stability of the newly established Han Dynasty, he divided many meritorious heroes and nobles of the old Six Kingdoms.
One of them was Han Wangxin, the grandson of King Han Xiang, who was sealed in Daidi, which bordered the Xiongnu.
In 201 BC, the Xiongnu leader Mao Dunshan had just unified the Mongolian Plateau and led 100,000 elites south. Han Wangxin fought with him, and because of the few victories and many defeats, in order to keep the peace, he wrote to seek reconciliation.
However, Liu Bang suspected that Han Wangxin was secretly communicating with the song and severely reprimanded, which made Han Wangxin frightened and uneasy, and finally took refuge in the Xiongnu and agreed to jointly attack the Han Dynasty.
In the winter of 200 BC, in order to maintain the stability of the frontier, Liu Bang personally led a large army to crusade against the Xiongnu and suppressed the rebellion of Han Wangxin.
The morale of the Han army was high, and it achieved several victories in the early days, defeating the armies of the Xiongnu and Han Wangxin. However, the victory gave the Han army the idea of underestimating the enemy.
In the long river of history, there is a legendary story about Mao Dunshan Yu and Liu Bang. In order to mislead the Han army, Mao Dunshan hid the elite horses and soldiers, deliberately revealing the weak side.
Liu Bang decided to seize the opportunity and led the light cavalry to pursue deeply, but he fell into the encirclement of the 400,000-strong Xiongnu army at Baishan Mountain.
However, what is puzzling is that Mao Dun Shan Yu did not take the opportunity to eliminate Liu Bang, but after seven days and seven nights of siege, under the persuasion of the Yan clan, he opened the encirclement and let Liu Bang go.
So, why did Maudon Shan make such a decision? This mystery has sparked the thinking and speculation of countless historians.
The reason why Liu Bang was able to escape at the critical moment was all due to the strategy of his adviser Chen Ping.
Chen Ping sent his men to bribe the Xiongnu clan, and according to historical records, Mao Dunshan Yu had a close relationship with the clan, so he listened to her slander and let Liu Bang go, thus losing the great opportunity to destroy the Han dynasty.
This explanation may seem reasonable, but those who really understand Maudun Shan Yu will scoff at it. Because Mao Dun Shan Yu is not an emotional person.
According to the record of "Historical Records: The Biography of the Huns", in order to train soldiers, he invented a kind of ringing arrow.
He ordered his soldiers to shoot along with him as soon as he hit the target with a ringing arrow. He even did not hesitate to use his beloved horses and women as training tools, and even his old Shan Yu was trained to death by him in this way.
Why did Mao Dunshan give up the siege of Liu Bang? It was not that he was swayed by a few words of pillow wind, but that he realized that it was not easy to defeat the founding emperor Liu Bang. Liu Bang's army has a strong will to fight, and they have all experienced the test of blood and fire.
Moreover, Liu Bang is good at fighting defensive battles, and has been besieged many times when fighting with the Qin army and Xiang Yu, but he has always stood tall.
Although the Xiongnu army was strong, due to the relatively backward bone arrows used by some of the soldiers, they might be at a disadvantage when fighting against the well-equipped Han army.
Moreover, the Han Dynasty reinforcements that were rushing were Liu Bang's savior, and as long as he could hold on for a while, the siege of the Xiongnu would not last long.
Another point is that the Xiongnu and Han Wangxin originally agreed to join forces to attack Liu Bang, but after the agreed time, Han Wangxin's troops were delayed.
Mao Dunshan guessed that this might be a conspiracy of Han Wangxin and the Han army, deliberately delaying time to eliminate the Xiongnu.
Since the Xiongnu are now unable to eliminate Liu Bang for the time being, the Han Dynasty also agreed to make peace and send precious gifts every year, which has achieved the purpose of the war, so the Xiongnu will naturally accept it when they meet it.
After escaping the predicament, Liu Bang realized that the nascent Han dynasty was not yet strong enough to compete with the Xiongnu, so he reluctantly adopted a decades-long policy of peace and proximity in order to ease tensions.
