Liu Bei and Cao Cao finally won the victory after many years of the Battle of Hanzhong, but Shu Han's national strength was also greatly damaged, and guan Yu also lost the land of Jingzhou. In order to realize the revival of the Han Dynasty, according to the strategy of "Longzhong Pair", it was the best way to send troops from Jingzhou, so Liu Bei led a large army to attack Eastern Wu in July 221 after two years of preparation, but he had no choice but to kill Lu Xun halfway and burn Liu Bei's army for seven hundred miles, and Liu Bei's army was defeated!
Liu Bei fled to the vicinity of the White Emperor's City and tried to seek another opportunity to attack Eastern Wu, but he could not help himself physically, and he died of illness after being isolated by Zhuge Liang and Li Yan! Around June 223, the local Haoqiang of Yizhou took advantage of the new defeat of shu Han and the death of Liu Bei to instigate a rebellion against Muke County, YueYue County, and Meng Yu, the leader of the ethnic minorities in Yizhou County. They held Emperor Shangao far away, believing that the Shu Han under Zhuge Liang's power could not help them, and they could rest assured that they could rebel.
In fact, in the three years after their rebellion, Zhuge Liang really did not pay much attention to them, but only sent emissaries to recruit security, but it did not work.
After Liu Bei's death, the newly established Shu Han was facing a serious crisis, sun and Liu's alliance had broken down, the Cao Wei army in the north was suppressed, and the Shu Han state was seriously depleted. For this reason, Zhuge Liang decided to first slow down the counter-rebellion in Southern China, after all, it was only the border area of Shu Han, and the impact on the entire Shu Han was not particularly large, and the top priority should be to send emissaries to repair the alliance with Eastern Wu and actively stabilize the order of Shu Han to restore national strength.
By 225, the time was ripe for shu han to put down the rebellion in southern China. In March of the same year, Zhuge Liang led about 30,000 troops to the south, joined the army Ma Chen personally sent tens of miles, and put forward the strategy of "attacking the heart first, attacking the city as the bottom, fighting the heart as the top, and fighting the army as the bottom", which Zhuge Liang adopted. Obviously, although these rebels were powerful, they lacked real strength, and by October Zhuge Liang had completed the counter-rebellion.
