He died before he could get out of the division, and the hero was in tears. This poem gives a very clear description of the end of Zhuge Liang's life. He was a genius who fought alongside Liu Bei and continued to devote himself to the Shu kingdom after Liu Bei's sudden death.
But in the end, it was doomed to be in vain, Shu was finally destroyed, Empress Liu Chan was captured, and a widely spread joke was left behind.
The demise of the Shu kingdom was not only Zhuge Liang's early death, but also because he cultivated four wrong people for the Shu Han, heralding the decline of the sun after the Shu Han.
One, the two wrong people - the Ma Mo brothers
The Chronicle of the Three Kingdoms records that Liu Bei warned Zhuge Liang before his death, telling him not to entrust important responsibilities to Ma Mo, otherwise it would inevitably lead to great disaster. As a result, Liu Bei did have a pair of sharp eyes that judged people, but unfortunately, this time Zhuge Liang did not listen to his master's words.
In fact, Ma Mo was talented, knowledgeable, and knowledgeable about the art of war, and it was good to have insight, but not to lack practice. And to promote the birth of the idiom Zhao Kuo, Ma Mo was full of clever strategies, but in the face of the real, rapidly changing battlefield, he was hasty and dazed.
Zhuge Liang had high hopes for Ma Mo, often helping him, and talking to him more often on weekdays. In the first Northern Expedition, as an important part of the grain road, the street kiosks were extremely dangerous, who should be guarded? After thinking about it, Zhuge Liang gave the task to Ma Chen.

Zhuge Liang
Shouldering such a heavy responsibility, but without the strength to match it, he disregarded his own environment, abandoned the street kiosk, chose to copy books, and based on the high, in the mountain array.
His opponent was Cao Cao's famous general Zhang Guo. Zhang Gao was a veteran with extensive experience in fighting against the enemy. He wouldn't play by the rules of the horse. He was flexible and did not rigidly formulate tactics, but analyzed the battle situation and gained insight into the weaknesses of the other side.
Zhang Gao sent troops to surround the high mountains occupied by the Shu army, so that the Shu army would not attack them day by day, and the land would not be smooth. Grain, grass and drinking water have been the lifeline of the army since ancient times. The lifeline is cut off. The Morale of the Shu army was low, and finally it scattered under the attack of the enemy.
Matthew
The elaborate northern expedition with lofty goals was forced to end hastily due to the loss of the Jieting pavilion and the cut off of the Shu army's grain route. Ma Mo did not die on the battlefield and was punished by military law. In the end, Zhuge Liang and Ma Mo burst into tears, still feeling sorry for this "talent".
Jiang Wei's brother is Ma Mo, but he is much older than Ma Mo. After all, Zhuge Liang regarded him as his successor. Unlike Ma Mo, Jiang Wei understands tactics, is more adaptable, and is a general who often wins.
So, there doesn't seem to be anything wrong with letting such a brave and shrewd person let go, so why zhuge Liang's fault?
Jiang Wei
Because Jiang Wei is good at war, warlike. As we all know, war is bound to bring indelible harm to the people and make their livelihoods poor. Therefore, the authorities should be cautious about military action, but Jiang Wei did not. In addition to the five Northern Expeditions before Zhuge Liang's death, Jiang Wei launched 11 wars in the 20 years after Zhuge Liang's death.
Therefore, Jiang Wei, blinded by the desire for victory, insisted on continuing the Northern Expedition to complete it. Zhuge Liang regretted it. He did not see that at this time, because of years of war, the Shu people could not rest in peace, and their national strength was declining day by day, and they could not withstand another war.
His northern expedition against popular opposition ended in a crushing defeat. At this time, the biggest threat to Shu was not a foreign enemy, but an internal worry, and Liu Chan favored eunuchs, and only hed pleasure would lead Shu to extinction. What he was supposed to do was to exhort the king to get rid of heresy, but he risked internal and external troubles to launch a war, and the Shu kingdom lost its last glory.
Second, the third wrong person - Dong Jie
This person's name sounds very strange, it seems to be an unknown general in history, but he is quite praised by Zhuge Liang, called a good scholar, which is a high evaluation, and it is also because Zhuge Liang attaches great importance to him that Zhuge Liang was able to reach the top.
After Zhuge Liang's death, the Shu kingdom was full of talents. He himself was very talented, and was praised by Zhuge Liang before his death, accumulating fame for him. Dong Yue served as a major minister.
In the late Shu Han Dynasty, it quickly went downhill, in addition to the reason for the talent fault, there was also the "helper" of the later master Liu Chan. Liu Chan himself was not good at his ability, and he did nothing to ascend the throne, and he was very mediocre, but what he should not do was to ignore Zhu Liang's warning that he was "close to the sages, far from the villains", but he was spoiled by the eunuch Huang Hao, so shu Han went downhill irreversibly.
Jun lost his morality and should be advised as a courtier, but Dongjue Shizhi knew a meal and turned a blind eye to the absurd status quo, which made Liu Chan more and more spoiled.
The most important thing is that after Dong Yue became an auxiliary general, he still ignored his own advice to the king, and saw that Liu Chan had gone astray but did not say a word.
Zhuge Liangming regarded Dong Yue as Liu Chan's master, but even if he was smart, he could not predict that Dong Yue would live up to his expectations after his death.
Liu Chan
The fourth wrong person- Zhuge Zhan
Zhuge Zhan was Zhuge Liang's biological son, he did not escape his father's hero, the son of magic, the courage and strategy were far inferior to his father, which was also the result of Zhuge Liang's deep cultivation.
With his father's glory, Zhuge Zhan in the Shu Han court also attached great importance to the position of Ping Shangshu, no merit, but the true gold scripture fire will only become more dazzling, but not the real gold will reveal its own gray in the flame.
Fire quietly descended in front of Shu Han. At the same time that Jiang Wei and Zhong Hui were in a bitter battle, Zhuge Zhan's capital city also encountered Deng Ai, who came to attack, and on the whole, Zhuge Zhan had the upper hand.
First, the military. Zhuge Zhan had 70,000 elite soldiers under his command, while Deng Ai only brought 30,000 elite soldiers. Deng Ai's men were certainly tired, but Zhuge Zhan defended his capital with high morale and favorable geographical location. The results were incredible. The Shu army was defeated, and Zhuge Zhan committed suicide.
Zhuge Zhan's fiasco directly led to shu han in crisis, so Liu Chan chose to surrender.
Heroes go to sea, and changes in the times are inevitable. No one can predict the impact of every decision on the future, even Zhuge Liang.
Therefore, we cannot deny Zhuge Liang's unexpected brilliance because of these four mistakes. He has done his best and done his duty, and this is the eternal praise of all.
