After besieging Liu Bang on Baishan Mountain for seven days and seven nights, the Xiongnu Shan Yu Mao Dun did not follow the trend to eliminate Liu Bang, but instead let him return unscathed. And this time, the sequelae brought about by this return are very large. Although the Han Dynasty raised obscurity in the years from Liu Bang to Liu Qi, when Emperor Wu of Han came to power, he pursued and attacked the Xiongnu. Judging from the achievements of Wei Qing, Huo Fuyi, and others, the Xiongnu were beaten quite badly against the Han Dynasty. Moreover, after Emperor Xuan of Han came to power, he still continued the policy of Emperor Wu of Han and continued to fight the Xiongnu, so that the Xiongnu almost reached the point of extinction.

In a sense, the practice of Mao Dun in those years was to raise tigers for trouble. If he killed Liu Bang cleanly when Liu Bang ran out of food, the newly established Han Dynasty would definitely perish. After the fall of the Han Dynasty, was there still the tragedy of its descendants being chased and beaten by the Han Dynasty?
Then, when Mao Dun could obviously take down Liu Bang with a single blow, why did he ghostly let Liu Bang go?
According to historical records, the reason why Mo Dun released Liu Bang was because Chen Ping used a strategy at that time. Chen Ping bribed Mo Dun's wife with heavy money, and at the same time told Mo Dun's wife that the Han Dynasty was ready to send a beautiful woman to Mo Dun, hoping that Mo Dun would let go of Liu Bang. On the one hand, Mo Dun's wife coveted the treasure sent by Chen Ping, and on the other hand, she was afraid that the beautiful woman given to Mo Dun by the Han Dynasty would take her place. Therefore, he hurried to tell Mo Dun that he could not kill Liu Bang completely. If they were exterminated and the Han Dynasty's rescuers came and retaliated against the Xiongnu, the Xiongnu would not be able to eat and leave.
Mo Dun felt that his wife was right, so he let Liu Bang go back.
Although the historical data says so, this statement of the historical data is obviously problematic. What's the problem? That is, if the Xiongnu killed Liu Bang, would the Han Dynasty's rescuers really come to pursue and beat the Xiongnu? Obviously, this is not possible. Why is it impossible?
(Liu Bang)
Because at that time, Liu Bang was encountering a rebellion by princes with different surnames. Although Liu Bang suppressed these princes with different surnames, the confidants of these princes with different surnames were still there, and their henchmen were still there. For example, Chen Feng was originally only the prime minister of Zhang Ao, the King of Zhao, and because he was dissatisfied with Liu Bang's bad attitude toward Zhang Ao, he raised an army to rebel. It can be seen from this that there are actually many henchmen of princes with different surnames.
If Liu Bang was killed by Mao Dun later, because the dragons were leaderless. The henchmen of the princes and princes of different surnames that Liu Bang had killed were bound to respond to everything and stand up and rebel. When the henchmen of those princes with different surnames stood up and rebelled, Liu Bang's subordinates Cao Shan, Zhou Bo, Dou Bao, and others were obviously unable to resist. Even if it can be resisted, everyone will fight, and there will be a situation of chaos in the world.
At this time, the chaos in the world is different from the previous chaos in the world. Before the world was in chaos, there were heroes like Liu Bang and Xiang Yu. Now there is no such figure, so it must be a pot of porridge.
If Zhongyuan made a pot of porridge, in fact, it was a perfect opportunity for Mo Dun. He could have taken the opportunity to go south and advance towards the Central Plains. In this way, he may occupy the Central Plains and become the lord of the Central Plains. If that were the case, the first minority regime to unify the Central Plains would not be the Yuan Dynasty a thousand years later, but the Xiongnu.
So, is it that Mao Dun does not have great talent? Of course not. Mouton was truly a magnate king who had killed his wife and his father very cold-bloodedly in order to obtain the throne of the Huns. Later, he conquered the east and the west, defeated many countries and tribes in the east and west, and established a country with a vast territory. A king like Mouton is unique in the entire history of the Xiongnu.

Since Mao Dun had such a great talent, why didn't he take Liu Bang and wait for a rebellion in the Central Plains to occur, and he went to unify the Jiangshan?
I think the main reason is that at that time, although Mo dun laid a sky in the north. However, he was not mentally prepared to attack the South.
The reason why I was not mentally prepared to attack the South. First, because the south has always been a place where civilizations have developed, and it has been a suzerainty since ancient times. This is what not only the South thinks, but also the minority nationalities in the North. Morton hit the countries and tribes of the east and the west, and he had no sense of fear. However, if you want to fight the Central Plains countries in the south, you are still very worried.
Second, the Xiongnu had suffered a heavy blow from the Central Plains countries before. For example, before Zhao Guo Li Mu struck at them, Qin Dynasty Mengtian struck at them. They knew that the Central Plains were powerful, but they did not dare to easily go to war with the Central Plains countries. Even if there is chaos in the Central Plains, his heart is still full of fear.
Third, although Liu Bang was besieged for seven days and seven nights, there was no guarantee that Liu Bang would be taken quickly. In case you can't take it, the rescue soldiers will arrive again, and you will be in trouble.
Of course, Mo Dun actually had a plot against Zhongyuan, for example, after Liu Bang's death, Mo Dun wrote to Lü Hou and said that he wanted to marry her. This also shows that Mao Dun really has the intention of plotting against zhongyuan. But that's all, big action is absolutely not dare.
