After that, Fu Jian began to reuse Wang Meng to govern the internal political and economic issues of the country, while he led the army to start a series of wars of national subjugation. In 370 AD, Fu Jian perished before Yan. The next year, he destroyed Yang on the edge of Qiu Chi. In 373 AD, Fu Jian captured Liangzhou and Yizhou in the Eastern Jin Dynasty, and its strength increased greatly. In 376 AD, Fu Jian died before Zhang and died in the same year. In 382 AD, Fu Jian sent people to the Western Regions.
At this point, Fu Jian's Daqin Empire reached its peak and the whole north was unified. Even the profit has become the territory of Fu Jian, which can be said to be the second state in the world. At that time, the Eastern Jin had only a small piece of territory in the southeast, which was really cowardly. But Fu Jian now has a problem, that is, the commanders in his army are basically descendants or subordinates of the king of national subjugation, and they have not cultivated much power. Although it embodies Fu Jian's eclectic pride, it has laid a hidden danger for its southern expedition. Wang Meng is very opposed to Fu Jian's expedition, because he thinks that Fu Jian will move Hu to Guanzhong, which will lead to chaos in the rear area and the generals in the army may rebel. Mu Rongchui of Xianbei nationality and Yao Chang of Qiang nationality actively supported Fu Jian's southern expedition because they wanted to restore the country. In the end, the battle of the Southern Expedition failed. Xie An in the Eastern Jin Dynasty reconciled the contradiction between Xie Jia and Jia Huan, and unified the spearhead, defeating the Fu Jian Group, which was at home and abroad. In this war, leaders of all ethnic groups, led by Mu Rongchui and Yao Chang, were self-reliant and had little to lose.
The most regrettable battle of the Northern Expedition was Emperor Wu of Song's Northern Expedition. Emperor Wu of Song is a legend and the spokesman of Liu Song. At that time, the civil strife in the Eastern Jin Dynasty continued, and after the Huan family rebelled, the Eastern Jin Dynasty was in a mess. At this time, Emperor Wu of Song, who had become the leader of the Northern Dynasties, began his own life. After he put down the rebellions in various places one by one, he reorganized the Eastern Jin Dynasty. Emperor Wu of song sent envoys to make peace with Qin and asked Nanxiang and other counties, and the king of Qin might make it. Ministers thought it was impossible, so they said: There is only one kind of goodness in the world. Emperor Wu of song lifted subtle, can win Huan Xuan, xingfu Jinshi, internal politics, foreign repair his government, how can I cherish several counties, not become beautiful! ? Twelve counties, such as Nanxiang, Xinye and Wuyin, were classified as gold. -"History as a Mirror" But his ambition goes far beyond this. At this time, he decisively chose the Northern Expedition. Because the post-Qin dynasty was just at the time of power transfer, the old emperor had just died, and the new emperor's position on the stage was not stable.
Whether it's the southern expedition or the northern expedition. Since Qin Shihuang ruled the country, all the governors wanted to compete in the Central Plains and become the people who ruled the country. However, this road is difficult, especially since there are many governors with the same aspirations. During the Three Kingdoms period, Cao Cao was fully capable of dominating the world, but when he met Liu Bei and Sun Quan, two governors at the same level, he could only stop. By the same token, the governors of the Northern and Southern Dynasties had their own problems without meeting their opponents. Fu Jian met Xie An, Emperor Wu of Song met Liu's death, while Tuoba Tao did.
