Mao Dundan besieged Liu Bang on Baishan Mountain for seven days and seven nights, when Liu Bang had no grain and grass inside and no reinforcements outside. It has reached the point of exhaustion.
Later, Chen Ping made a counter-plan, bribed Mo Dun Shan Yu's wife Fu Shi, and told Fu Shi that the Han Dynasty would offer a beautiful woman to Mo Dun Shan Yu and ask Mo Dun Shan Yu for peace. The Fu clan was afraid of falling out of favor, so he said to Mo Dundanyu, if you kill Liu Bang, the Han Dynasty will certainly not give up. Moreover, perhaps Liu Bang's reinforcements will soon arrive. At that time, we were attacked by two sides, and we couldn't win the fight. Mao Dun listened to Fu Shi's words, so he released Liu Bang and withdrew his troops and returned.

In fact, at that time, Mao Dundan could completely take Liu Bang down. After all, Liu Bang had been besieged for seven days and seven nights. You must know that Liu Bang threw away the heavy grain and grass and chased after him in a long-distance attack. Trapped in Mount Baishan for seven days and seven nights, he had run out of food and grass. With just one blow, Mao Dun could beat Liu Bang to death. After all, Mao Dundan had an army of 400,000 at that time, and the troops were quite strong, which was more than enough to deal with Liu Bang.
As for whether Liu Bang had reinforcements or not, Mao Dun could have sent spies to investigate. As long as reinforcements are detected, they can not only encircle the point to provide reinforcements, but also withdraw their troops at any time. No reinforcements. Then keep fighting.
It can be seen from this that it is very strange that Mao Dun is in a hurry to withdraw his troops.
One could argue that Mo Dundan felt at the time that his wife Fu Shi had made a lot of sense. He was indeed afraid that the Han Dynasty would retaliate against him.
If it is an ordinary Xiongnu Shan Yu, afraid of retaliation by the Han Dynasty, it is certain. But Mao Dun was different, he had just unified the Xiongnu, and also defeated the Eastern Hu in the east, defeated the Yue clan in the west, and had a wide territory. Moreover, Mo Dundan yu also trained a strong army through the sound of dysprosium. This army can fight wherever it wants, and its combat effectiveness is quite strong, which can be regarded as one of the most powerful armies at that time. How could such a Mao Dun be afraid of the Han Dynasty?

Besides, if it was the previous Qin Dynasty, Mao Dun was still a little afraid. After all, Montien had made them pay a heavy price. However, the Qin Dynasty had already perished, and after the peasant revolt at the end of the Qin Dynasty and the struggle between the Chu and Han Dynasties, the Han Dynasty, a country that was poor and white, was simply not capable of confronting the Xiongnu.
Another point is that the Han Dynasty at that time was in a very delicate time. Those princes with different surnames supported themselves and did not obey Liu Bang's orders. Liu Bang had already wiped out so many of the princes with different surnames that there were no generals to fight for him.
In short, Liu Bang and the princes had great contradictions at that time. Even if Liu Bang was killed by Mao Dundan, these princes would definitely not take revenge. It can be seen that Mouton has encountered a once-in-a-lifetime opportunity.
Some people may also say that Mo Dun does not fight because he listens to his wife Fu Shi's words more, because he loves his wife very much.
I would like to say that if there is such an understanding, it is completely ignorant of Morton. You know, in the process of ascending to the highest position of power, Mo Dun was very fierce. He killed his father and his wife for this. And he killed his wife not because she had made any mistakes, but because he was training his army to obey his command absolutely.
At that time, Mo dun shot the sounding dagger at his wife, demanding that the soldiers must shoot at his wife. Those soldiers who did not dare to shoot, Moton killed them all.
How could he listen to his wife when he used to use him as a target for training?
(Liu Bang stills)
So, why did Mao Dun let go of Liu Bang in a good situation?
I think the most fundamental reason is that Mo Dun was not ready to take the Han Dynasty at that time. This includes psychological preparation and military preparation. After all, the Xiongnu have always been suppressed and beaten by the Central Plains countries, and they lack confidence. If he rushes to kill Liu Bang. Although it is said that at that time, it may not be that someone immediately sought revenge on him. But with the Liang Zi of the Han Dynasty, it was knotted. After that, as long as the Han Dynasty eased his breath, it would beat him to death. In that case, the Huns would not have a good life.
Conversely, if Liu Bang is released. Liu Bang knew that the Xiongnu were powerful, and he would not send troops to beat him casually after that, so that his pressure would not be great, and he could prepare calmly.
In fact, until Liu Bang died and Lü Hou came to power, Mao Dun was still not ready. At that time, he wrote a very unreasonable letter to Lü Hou, saying that he wanted to marry Lü Hou. He wanted to use this method to annex the land of the Han Dynasty. Lü Hou was soft at that time, replied to Yanchi humble, and also offered some beautiful women to him.
Morton was no more, and there was no further action.
However, it has to be said that Mouton did lose a once-in-a-lifetime opportunity. He missed this opportunity, and when the Han Dynasty was revived and strengthened, the huns came to an end. Emperor Wu of Han dealt a fatal blow to the Xiongnu, driving them far away. It can be said that it was really a risk to miss the fighter plane and harm his children and grandchildren.
