<h1 class="pgc-h-arrow-right" data-track="2" > introduction:</h1>
In 201 BC, a war of internal and external collusion broke out.
In collusion with Han Wangxin, Mao Dunshan invaded the northern part of Shanxi in one fell swoop, and once killed the city of Taiyuan.
If it were not for Liu Bang leading a large army to force the Xiongnu to retreat beyond the Great Wall, the Xiongnu would probably have gone further, and after annexing the Hetao area, it would have been possible to continue to invade and conquer the prefecture. All this put the Han Dynasty, which had just completed its unification, into a dangerous situation.

(Situation in the early Western Han Dynasty)
At the turn of the Qin and Han Dynasties, the unification of the Han Dynasty and the Xiongnu was completed almost at the same time!
After the reunification, the Xiongnu reoccupied the hetao area that was originally stable during the Qin Shi Huang period, and took advantage of the turmoil in the Central Plains to almost destroy the northern barrier established by Qin Shi Huang.
The Xiongnu soldiers came to the city at the moment, making it difficult for the Han Dynasty to sleep and eat.
Although the Han Dynasty and the Xiongnu began to make peace after the Siege of Baideng, and the two sides maintained a superficial peace, there was still a lot of confrontation between the two regimes. In the early period of the Han Dynasty, in this way, peace was exchanged for peace, and the strategy of Taoguang and obscurity was practiced to accumulate strength.
Finally, in the era of Emperor Wu of Han, a comprehensive counterattack belonging to the Han Dynasty was ushered in.
(Emperor Wu of the Han Dynasty was born in accordance with the times of heaven)
<h1 class="pgc-h-arrow-right" data-track="62" >: It is difficult to expect the Huns to keep their word. </h1>
After Emperor Wu of Han succeeded to the throne, he began to prepare for the war against the Xiongnu, and after the death of his grandmother Empress Dou, he broke free of the shackles and began the war that lasted for 44 years.
In 1944, the duration of this War between China and Hungary was so long that the intensity of the war was undoubtedly rare in the world.
So, why did Emperor Wudi of han always be reluctant to let go of the Xiongnu? The answer is simple!
Because Emperor Wudi of the Han Dynasty deeply understood that the threat of the steppe nomads to the Central Plains Dynasty was objectively existent, even if the Han-Hungarians were close, this threat would not be lifted.
If the Han Dynasty did not attack the Xiongnu when it was strong, then when the Han Dynasty was weak, the Xiongnu would definitely kick their noses in the face.
Emperor Wudi of the Han Dynasty understood that peace was not a panacea for peace, and it was undoubtedly nonsense to expect women to maintain peace.
As a stopgap measure, the peace is just a symbol of mutual agreement between trustworthy people, if the Huns keep their promises, it may be useful, if they encounter those who do not keep their promises, it is a disaster.
(Han Dynasty and Pro)
And this is also evidenced by real wars!
In the winter of 166 BC, before Emperor Wu of the Han Dynasty, a treacherous war broke out among the Xiongnu.
In that year, Emperor Wen of Han had just married a clan princess and sent a large amount of supplies in the hope of gaining peace for a while.
Who ever thought that the Xiongnu did not have any gratitude, Lao Shangshan Yu without warning dispatched 140,000 elite horsemen to invade the Han Dynasty, killing people and setting fires all the way, burning and plundering, making the Han-Hungarian border people unhappy.
The Xiongnu army drove straight in and actually hit jingchuan county in Gansu, which was only 200 kilometers away from Chang'an. It was also in this year that the young Li Guang joined the army as a teenager, killed a lot of enemies in the battle against the Xiongnu, won the appreciation of Emperor Wen of Han, and began his life against the Xiongnu.

<h1 class="pgc-h-arrow-right" data-track="63" >2: The Way the Huns fought determined that they could fight whenever they wanted. </h1>
In the seemingly peaceful confrontation between the Han Dynasty and the Xiongnu, the difference in the way the two sides fought determined that the Han Dynasty could only choose passive defense in the face of the Xiongnu's provocations.
The Huns' way of fighting, in short, did not need logistical supplies, and fought wherever they wanted.
This way of fighting is actually very suitable for their way of life.
As long as there is abundant water grass, it is the homeland of the Huns, and where the water and grass are abundant, they will go where they go. The same is true when fighting, where oil and water can rob more rich people, and there is not much danger, where is their battlefield.
Guerrilla warfare, mobile warfare, and targeted attacks based on this were the main methods of warfare in which the Huns harassed the Han Dynasty.
This way of fighting is destined to be in the all-round confrontation defense, and the Han Dynasty is in the ascendant!
Compared with the Xiongnu who were accustomed to sports warfare, the long-term farming habits and the way of life of building and defending the city made the han dynasty soldiers and civilians inseparable from cultivated land and cities.
One side can only hold out, the other side is committed to movement warfare, and the Han Dynasty does not have many good methods in the face of the Xiongnu except passive counterattack.

<h1 class="pgc-h-arrow-right" data-track="64" > three: the thoughts of Emperor Wu of Han. </h1>
Expecting the treacherous Huns to abide by the peace agreement, respect and affection is undoubtedly a false proposition.
Giving money to women is still constantly harassing, always facing the fate of being stabbed in the neck, what should the Han Dynasty do?
There is only one answer, that is, the whole army war and the Huns.
This is a forced move, but also a war that has to be done!
Because if they don't fight back, the Huns will also come in, today, tomorrow, day after day, making people overwhelmed!
Therefore, after experiencing the humiliation of Han Gaozu and Lü Hou and the accumulation of Wenjing's rule, Emperor Wu of Han appeared with the sense of mission given to him by history.
(The sense of mission of Emperor Wu of Han)
The moment Emperor Wu of Han ascended to the throne, he was burdened with the mission of the first six rulers of the Han Dynasty.
This mission made him have to wield the whip, he had to fight all the time.
Because after missing him, Emperor Wudi of Han was not sure whether his descendants could have the same excellent qualities and opportunities as their predecessors.
From the founding of the Han Dynasty until the time of Emperor Wu of the Han Dynasty, the Xiongnu and the Han Dynasty fought for more than 70 years, and the Xiongnu have always taken the initiative but have never had the opportunity to enter the Central Plains.
There are only three reasons for this.
First of all: compared with the Han Dynasty, the Xiongnu seem to be strong and the population has not been large.
Behind the strong soldiers, the shortcomings of the nomadic tribes are undoubtedly exposed.
That's why they're committed to capturing the key to population, expanding their populations in order to get more soldiers, and fulfilling their ambitions. If they are given the opportunity to take advantage of the population and dedicate themselves to the reproduction of the population, it is difficult to say what will happen in the future and what the consequences will be.
(The Han Dynasty was stronger)
Secondly, it is the result of the ming monarchy of all the rulers in the first 70 years of the Han Dynasty.
Han Gaozu and Lü Hou continued to relay, adhering to the technique of Huang Lao, restoring the national strength of the early Han Dynasty, and the rebellion of Lü Hou entered the era of Wenjing rule in a small episode, and the relay governance of this group of Han Dynasty kings, as well as the attitude of respecting Small and Cautious, did not give the Xiongnu any opportunity to touch the fish in muddy waters.
But who can guarantee that the Ming Emperor will have it every year? That's a limited edition not a popular version.
Emperor Wu of Han only thought that he was a male lord, and he would definitely worry about whether his descendants were the same as himself.
If future generations produce a dim-witted emperor, won't leaving the Huns behind themselves cause trouble for their descendants? If you don't do well, you will still have the worry of destroying the country.
(Emperor Wu of the Han Dynasty)
Finally: after enjoying the welfare of your grandparents, you must do what your grandparents want to do.
In fact, the Han Dynasty's search for a Jedi counterattack against the Xiongnu was not something that only happened when Emperor Wu of han was there.
As early as the era of Emperor Wen of Han, Emperor Wen of Han had thought of personally leading soldiers and horses to go out to mobei to solve the Xiongnu problem once and for all, but was later stopped by Empress Bo, but this thought was never forgotten, but it was passed on to Emperor Jing of Han.
During the era of the Han Jing Emperor, in order to strengthen the centralization of power, the appointment of Chao mistaken immigrants to the actual border and the cutting of the domain were also in preparation for the subsequent counterattack against the Xiongnu.
Without emigration to enrich the frontier population, there was no basis for counterattack in the era of Emperor Wu of Han, no reason for cutting the domain and subsequently quelling the rebellion of the Eight Kings, and there was no result of the increase in the central strength of the era of Emperor Wu of Han.
The great things that Emperor Jingdi of Han jing did with all his heart were to pave the way for Emperor Wudi of Han, and the Xiongnu problem that he devoted his life to solving was of course remembered by Emperor Wudi of Han.
(Emperor Jing of the Han Dynasty paved the way for him)
<h1 class="pgc-h-arrow-right" data-track="65" > epilogue:</h1>
As a practitioner of the wishes of successive rulers of the Han Dynasty, Emperor Wudi of the Han Dynasty actually had a sense of historical mission from the moment he ascended to the imperial throne. This sense of mission is to reverse the offensive and defensive momentum of the Xiongnu and the Han Dynasty, so that the Han Dynasty can really stand up in front of the Xiongnu.
The so-called generation of people to do a generation of things is this truth, father and grandfather and countless ancestors laid the foundation for themselves to fight back, do not fight to leave it to their children and grandchildren to fight?
Their own ability to know, the ability of their descendants can not be predicted, is it not a mistake to really have a bad father's offspring?
It can be seen from this that this Emperor Wudi of the Han Dynasty insisted on fighting the Xiongnu for more than 40 years after coming to power, which is actually the same reason that the later Tang Dynasty devoted itself to attacking Goguryeo and the three generations of the Qing Dynasty Kangqian Shengshi devoted themselves to beating The Quasi-Gar.
If you have the ability to lead the war and the strength to solve problems, then fight.
In order to avoid war, and leave the problem to future generations, if you try to have a fictitious title of "Renjun", you will become a confused father like the Emperor of Zhao and Song, so that the country will gradually be corroded in peace, and the last touch will collapse, which is the biggest irresponsibility.
