After Liu Yuan rebelled against Sima Ying and established the "State of Han", he was the first to establish the capital at Guocheng (国城, in modern Lüliang, Shanxi). Later, there was a great famine in the state, and the famine in the north-central part of the state was the worst. The Great Famine did not distinguish between the enemy and the enemy, and Sima Teng and Liu Yuan of the Han Kingdom could not bear it.
Sima Teng, with a population of 20,000, crossed the Taihang Mountains and went east to Jizhou and Yanzhou to avoid famine. Liu Yuan also had to move the capital twice: first to Liting (present-day Changzhi, Shanxi) and then to Puzi (蒲子, in modern Linfen, Shanxi). Circling around, Liu Yuan's base area has not been much large, that is, from the central to southern part of Hezhou (Shanxi).
In the Western Jin Dynasty, Sima Yue, the king of the East China Sea, won the "Rebellion of the Eight Kings". Wang Jun of Youzhou, Zhang Rail of Liangzhou, and Gou Xi of Yanzhou each have the strength to be underestimated, and each one has the strength to single out Liu Yuan's Xiongnu Han Kingdom.

Why did Liu Yuan's Han kingdom grow bigger, while the Western Jin warlords all lost?
The new Han Dynasty, with its fierce soldiers and horses, took it as its duty to cut down the Jin and Xing Xiongnu; ambitious, with the goal of replacing the Western Jin Dynasty for world domination.
The warlords of the Western Jin Dynasty were either intoxicated with infighting, or vying for power and profit, or one side divided to preserve their strength. Their greatest wish, at best, was to be a vassal of an empty emperor. Sima Yue, who has unlimited scenery, is like this, and so is Gou Xi, who is famous for a while.
Others, some of them are also ambitious, but they are hidden. He wanted the title of a loyal subject of the Jin Dynasty, and he also wanted the name of an emperor to be addicted. Zhang Rail and Wang Jun are like this.
For Sima Chi (Emperor Huai of Jin), the emperor of the Western Jin Dynasty, Liu Yuan was a real rebellion on the outside, and his own imperial court was a false loyalty inside--after the chaos of the world, this was the contest between the real villain and the hypocrite, and the emperor was just a spectator.
This is also a contest between dreams and desires, hypocrites want to see the sky out, can hold the throne to be the emperor, can not hold the throne to be a false loyalist. And Liu Yuan's fierce insistence on fighting and establishing himself as king is to tell the people of the world: I just want to change the heavens and the earth - so the guan is Hu is Han, Liu Yuan's supporters and defectors, there are really many.
After the "Rebellion of the Eight Kings" in the Western Jin Dynasty, internal infighting continued, just like the weeds on the plains, and the spring wind blew again. When Gou Xi, the first general of the Western Jin Dynasty, and Sima Yue, the first powerful minister, were originally brothers in a state of righteousness, when they fell out and beat each other up, Liu Yuan and the Xiongnu Han State made an immature plan for hegemony, taking hegemony in two steps: attacking three ways, taking Luoyang first, and then attacking Chang'an.
After the "Rebellion of the Eight Kings" and Liu Yuan's founding, there were still many forces in the Western Jin Dynasty, but the warlord division had already taken shape. It is not so much "Five Hu Chaohua" as it is the civil strife of the warlords of the Yiguan Clan and the great wars of the princes. The main people who fought against Liu Yuan were Sima Yue's forces, and only within Sima Yue's forces there was constant infighting.
Even so, the chaotic Sima Zhao court, Liu Yuan was not casually manipulated. In the first four years, Liu Yuan and the local warlords of the Western Jin Dynasty, you and I, attacked each other, each with its own victory and defeat, very lively, but also did not make progress - the Han Kingdom attacked Luoyang twice in a row, and both returned home.
But it's okay, a dream without setbacks is not a dream. Only through setbacks can we find the right route.
In 308, Liu Yuan officially declared himself emperor, and as the Han Dynasty surrendered more and more generals, the infighting among the Warlords of the Western Jin Dynasty became more and more serious, and the Han State's war against the Western Jin Dynasty took a major strategic turn.
Instead of attacking Luoyang, the capital of the Western Jin Dynasty, the Han State made a destructive attack on the surrounding areas of Luoyang, which then attacked the ruling base of the Western Jin Dynasty, depriving the Western Jin Dynasty of its war potential, and the ultimate goal was to take Luoyang lightly.
This kind of thinking can be said to be a point of chaos and a point of difficulty, and it can also be regarded as the prototype of the countryside surrounding the city, without ancients before and practitioners after that.
In order to isolate Luoyang, Liu Yuan hanguo sent several soldiers and horses. Shi Le, Wang Mi, Liu Cong, Liu Yao, and Liu Jing were in the Central Plains and attacked the county capitals of the Western Jin Dynasty, all with the goal of destroying the foundation of Western Jin rule.
In particular, Shi Le and Wang Mi launched a large offensive against Qingzhou, Xuzhou, Yuzhou, and Yanzhou, and a large-scale movement war and a sabotage war were used in everything (from Hebei to Hubei), and the manpower and material resources around the Central Plains were no longer used by the Western Jin Dynasty court.
In this situation, the Western Jin court had to consider moving the capital. The move of the capital was undecided, and Sima Chi, Gou Xi, and Sima Yue became infighting, and Sima Yue cried out in sorrow. The Western Jin Dynasty, which was originally in turmoil, even the characters who last supported the scene were gone.
The Western Jin Dynasty, which was already in a mess, was also divided into two groups. One group, led by Wang Yan and in the name of burying Sima Yue in the East China Sea, actually wanted to flee to the southeast; the other group, led by Emperor Huai of Jin and Gou Xi, trapped Luoyang and planned to move the capital to Cangyuan.
Both groups have problems. The wave of fleeing eastwards, dragging the family and taking the mouth, 100,000 soldiers and civilians, but there is no military commander who can carry the task. Wang Yanqing had more than enough to talk about, and militarily even the soldiers on paper were laymen, and this wave of people could not even compare with the rabble, at best a group of two-legged sheep.
This group of people trapped in Luoyang was a famous general Gou Xi, but unfortunately there were generals without soldiers. Gou Xi and Emperor Huai of Jin wanted to move the capital to Cangyuan, but they were robbed by thieves and bandits and had to return to Luoyang—they had already fallen into such a situation.
Everyone can see that this is the dream gift package given by heaven to the Xiongnu Han Kingdom, and this year is 311.
In the previous year, Liu Yuan died, Liu He succeeded to the throne, and the Xiongnu Han Kingdom staged a drama in which the emperor cut the domain and the king of the domain rebelled, and Liu Cong, the king of Chu, killed the emperor's brother Liu He and successfully ascended the throne.
Liu Cong fulfilled half of his father Liu Yuan's dream of destroying the Western Jin Dynasty and replacing it. Why half said? The destruction of the Western Jin Dynasty was done, and in its place, it did not seem to be too late.
Liu Cong seized the opportunity to launch the Campaign to Destroy the Western Jin Dynasty.
The Shile cavalry surrounded and killed the group of people who fled east, and none of the 100,000 two-legged sheep were spared. Hu Yanyan surrounded the group that was trapped in Luoyang. In the end, Liu Yao, Wang Mi, and Shi Le besieged Luoyang and fought a battle. Emperor Huai of Jin was captured, and the royal family members were taken captive for countless times (in fact, the Western Jin Dynasty was already considered a subjugated country).
Two years later, Emperor Huai of Jin was killed, and several ministers with different thoughts made Emperor Huan of Jin emperor, still falling in love with each other, and infighting continued. Emperor Huan of Jin had no soldiers and no power, but only a vain name, and three years later became a prisoner of Liu Cong, and the Western Jin Dynasty officially perished.
......
The "Rebellion of the Eight Kings" of the Western Jin Dynasty caused a warlord scuffle, which led to the confusion of the people of the Western Jin Dynasty and the disintegration of the people.
While Liu Cong killed the emperor's brother and established himself as emperor, the Xiongnu Han Kingdom also experienced imperial civil strife. Although Liu Cong destroyed the Western Jin Dynasty, Liu Yao, Wang Mi, and Shi Le, who sat on the throne, and the three strong generals of the Xiongnu Han Kingdom, were contradictory. Liu Cong's usurpation of the throne also sowed the seeds of the demise of the Xiongnu Han State.
