After Liu Bang successfully defeated Xiang Yu, he once said that the three keys to his victory over the world were Han Xin, Zhang Liang and Xiao He, which is also known as the Three Masters of the Han Dynasty.
Among the three masters of the Han Dynasty, in terms of who is the most important, I think it should be Han Xin. This is not to say that Xiao He and Zhang Liang are not important, but in this chaotic world, force is always the most important. It is said that in the Chu-Han War, after Han Xin pacified Qi and Zhao, he was actually qualified to divide the world into three parts, which is enough to prove that force is more important than strategy and logistics. What is even more rare is that Han Xin is not only good at military, but also has good strategy.

However, it was such a famous general who could not die well in his later years and was killed by Lü Hou. After Liu Bang saw the news that Han Xin was dead, the history books recorded that he was "happy and pitiful."
Then, did Liu Bang respect this very threatening meritorious man, or did he revere the talent more than the one who cherished the talent?
Han Xin's merits
Han Xin played a great role in Liu Bang's imperial work. From the time Han Xin was recommended by Xiao He to the time Han Xin was worshiped by Liu Bang as a great general, Han Xin began a life of kaihang.
After Xiang Yu divided the princes, because he was aware of Liu Bang's ambitions, he divided the original Qin Dynasty's homeland and the land of Bashu to him.
This place was originally used by the Qin State to imprison criminals. Although this place is rich, just like the relationship between the Qin state and the Bashu state in the Warring States period, it is not easy for the land of Bashu to go out.
Even so, Xiang Yu was not at ease, and he also deliberately sealed several Qin Dynasty generals in the original Guanzhong land of the Qin Dynasty, commonly known as the Three Qins, to monitor Liu Bang's every move.
Before Entering Bashu, in order to paralyze Xiang Yu, Liu Bang once burned the boardwalk out of Bashu to show that he had no intention of going east. After Liu Bang worshiped Han Xin as a general, Han Xin made a plan and openly sent people to repair the burned-out boardwalk, but in fact secretly detoured Chen Cang and raided the land of Three Qin.
However, Sanqin was originally a member of the Qin Dynasty, but he surrendered to Xiang Yu, causing the Qin Dynasty to perish. Naturally, the people of the Qin Kingdom hated these people to the bone.
In contrast, there are the three chapters of the Covenant law after Liu Bang entered Xianyang. Now that Liu Bang's army has returned again, the people of the Qin state have welcomed it. Therefore, the Three Qins guarding outside Liu Bang were quickly defeated. And Liu Bang also had the capital that the Qin state annexed the world, and the Qin state guanzhong bashu land.
Unfortunately, Liu Bang was severely attacked by Xiang Yu in Pengcheng and suffered a major defeat, fortunately Han Xin defeated Xiang Yu's pursuers, giving Liu Bang the opportunity to regroup.
However, the situation at this time was very unfavorable to Liu Bang, because those princes in the north saw Liu Bang's great defeat and surrendered to Xiang Yu one after another to show their loyalty.
Although these princes were some wall grass and not enough to be afraid of, they were still able to cause a two-sided attack on Liu Bang with Xiang Yu.
At this time, Han Xin stood up again and volunteered to go to the north to open up a battlefield behind enemy lines and clean up these wall grasses first.
In this process, Han Xin not only won many battles and victories, but also sent troops to assist Liu Bang from time to time. After all, it was still not easy to resist the attack of the Overlord Xiang Yu.
The final result was exactly what everyone knew, Han Xin successively eliminated the princes in the north, and even The general Long Ji under Xiang Yu was killed by Han Xin. At this time, Xiang Yu looked like the general trend had gone.
Therefore, the arrogant Xiang Yu also began to bow his head, choosing to surrender to Han Xin and invite him to divide the world. To be honest, if Han Xin established himself as king at this time, there was a great chance of dividing the world into three parts. Although the final victory is still unclear, at least it will make liu bang not so easy to claim the title of emperor.
However, in the face of such a temptation, Han Xin refused. The consequence of Han Xin's refusal was that Xiang Yu killed himself and Liu Bang became emperor.
Liu Bang's complicated feelings for Han Xin
Liu Bang knew and understood Han Xin's merits over the years, and he could even guess that Xiang Yu invited Han Xin to divide the world, but Liu Bang still accepted Han Xin's military power and degraded him again and again.
Because Han Xin is so terrible.
Han Xin was always unknown, and it only took a few years to become famous in the world. Many people have such a question, the same is familiar with the art of war, Zhao Kuo talked about soldiers on paper, the first battle failed, and since then it has been left behind for thousands of years. Han Xin had previously been familiar with the art of war, and there was no chance to practice at all, but he directly became a great general and also set three Qin.
For people like Han Xin, I can only describe it as talented. Are there many such people? Not much, Han Xin counted one, and Xu Da under Zhu Yuanzhang also counted one.
Han Xin was originally just a scoundrel who mixed food and drink, and Xu Da was originally just a farmer, but they were extremely fast-growing, or natural generals.
And Liu Bang witnessed the rise of Han Xin throughout the whole process. Because of this, he understood Han Xin's terribleness. Therefore, Han Xin could not have military power.
However, Liu Bang was ultimately intolerant, so after seizing Han Xin's military power, he chose to make Han Xin a rich man.
In fact, from Liu Bang's attitude towards these kings with different surnames, we can see Liu Bang's complicated feelings for Han Xin. Other people, Liu Bang did not seize power over them, but because of this, Liu Bang must get rid of these people.
Han Xin was different, han xin was first the king of Qi, then demoted to the king of Chu, and finally became the Marquis of Huaiyin. Liu Bang seized his power, which also meant that as long as Han Xin did not make trouble, he could survive. Liu Bang gave him a chance.
Unfortunately, Han Xin finally reversed.
Therefore, when Liu Bang saw Han Xin rebelling, he would be happy and pity. Xi is glad that he had foresight and took away Han Xin's military power in time, otherwise it would be unimaginable; pity is pity that he obviously gave Han Xin a chance, but Han Xin still embarked on this road.
Conclusion
Therefore, for the Han Dynasty, Liu Bang did not regret treating Han Xin in this way, but for him personally, it should be regretted.
