In ancient history, the monarch who can afford to be the "emperor of thousands of years" is naturally Qin Shi Huang, and it is difficult for historians to find a existence comparable to Yingzheng, but only he is an exception, which is Liu Che, the Emperor of the Han Dynasty.
As the 7th emperor of the Western Han Dynasty, during the reign of Emperor Wu of han, he expanded the territory of the Han Dynasty as never before, laying the foundation for the strength and prosperity of the Han Dynasty, and since then it has left its name in history.
It is worth mentioning that during the 55-year reign of Emperor Wu of the Han Dynasty, the nomadic Xiongnu in the north also had a deep connection with him. From 129 BC onwards, Emperor Wudi of han spent 44 years attacking the Xiongnu, and Emperor Wudi of Han was also the first emperor in Chinese history to require nomadic peoples to submit to the Central Plains Dynasty, which can't help but make people wonder, in fact, you see what the Xiongnu did in those years, you can understand
As early as the Warring States period, the Xiongnu in the north had become a great threat, zhao yan qin three kingdoms built walls to resist the invasion of the Xiongnu, and in the qin shi huang period, sent Meng Tian sent 300,000 troops to defeat the Xiongnu, as mentioned in the "Theory of Passing the Qin": "But the Xiongnu more than seven hundred miles, the Hu people did not dare to go south and herd horses." However, this did not completely disintegrate the power of the Xiongnu, the Xiongnu have strong mobility, geographical remoteness, they can still make a comeback after a period of time, even if they are as powerful as Qin Shi Huang, they can only build the Great Wall and passively take defensive measures, which just reflects the helplessness of the Central Plains Dynasty for the Xiongnu.
After the fall of the Qin Dynasty, the Xiongnu continued to invade again, and the "Records of History" mentioned: "Meng Tian died, the princes (rebelled) Qin, China was disturbed, and all those who moved to the qin were restored, so the Xiongnu were forgiven." And the history of the Han Dynasty monarchs' grievances against the Xiongnu has also begun.
After unifying the Central Plains, Liu Bang once led an army of 320,000 to conquer the Xiongnu in 200 AD, but suffered heavy losses, was besieged in Baishan Mountain for seven days and seven nights, and was forced to accept bribes from the Xiongnu wife before escaping ascension.
From then on, Liu Bang began to be patient, formulating a humiliating and pro-family policy, Andun Shan came with soldiers to invade, Liu Bang once planned to marry his daughter Princess Lu Yuan, in addition, the Han Dynasty rulers also adopted the means of "breaking the wealth and eliminating disasters", that is, Nagong, "(Xiongnu) greedy Han heavy coins." In the old age, the Han Dynasty left the rest of the goods (han surplus and the Xiongnu rare goods) to ask for the will (gift). However, this did not curb the ambitions of the Xiongnu, after signing the treaty with the Han, the Xiongnu repeatedly invaded the territory, and liu Bang killed more than a dozen ministers who thought that the Xiongnu were vulnerable before the Siege of Baideng, but for the Xiongnu, they still did not dare to make a big move.
After Liu Bang's death, the Xiongnu Shan Yu unexpectedly sent emissaries to send letters, believing that since Liu Bang, who had befriended Shan Yu as brothers, had died, according to the principle of the Xiongnu succession marriage system, he demanded that his widow Lü Hou be married to the grasslands, "When a brother dies, he will take his wife and wife." When Lü Hou heard this, he was furious and planned to "behead his emissaries and send troops to attack them", but under the bitter persuasion of the ministers, even Lü Hou, who was usually decisive in killing and fierce, also realized the gap between the Han Dynasty and the Xiongnu and once again tolerated it.
As for the later Han Wen Emperor Han Jingdi, the Xiongnu also always played a kind of "what can you do to me", for example, in 166 BC, Lao Shangdan Yu led 140,000 cavalry to attack 300 miles away from Chang'an, and retreated under the resistance of the Han army. However, the thick-skinned old Shangdan Yu, not long after this incident, once again sent an emissary to ask for relatives like a nobody, thinking that "the past ... Not enough to leave the joy of brothers", Emperor Wen of Han agreed, and sent a team of peacemakers.
Fortunately, several Han Dynasty rulers, including Lü Hou, were still reliable, so they did not let the Xiongnu cause greater disasters, otherwise, the Han Dynasty probably had no chance of continuing for 400 years.
In the past hundred years, the Xiongnu have always been like the sword of Damocles hanging over the head of the Emperor of the Han Dynasty, which made the emperors surnamed Liu grumble, and the hands of Emperor Wu of the Han Dynasty, after several generations of accumulation, coupled with the further improvement of the military system, finally had the capital to wage war against the Xiongnu, Liu Che also realized that if the Xiongnu were not completely defeated, they would eventually come back again, so this battle lasted for 44 years, depleting the strength of the Xiongnu, so that by the end of the Three Kingdoms, their vitality was still not restored.
