Zhuge Liang's main job did not exist as a strategist, because Liu Bei went out with the law. In the history of the Three Kingdoms, Chen Shou's evaluation of Zhuge Liang was average, but his military ability was not long. Although Zhuge Liang later led troops to pacify barbarians and led troops to the northern expedition many times, in fact, before Liu Bei died, Zhuge Liang's military talents were not greatly displayed. So in fact, his brilliant deeds in the Romance of the Three Kingdoms are greatly discounted.
Zhuge Liang, as an eternal phase, mainly contributed to internal affairs. During the establishment of the Shu-Han regime, Zhuge Liang was mainly engaged in diplomatic and government affairs activities and was a politician. He went to Jiangdong and successfully concluded a friendly treaty with Soochow, which eliminated the hidden dangers of Liu Bei's regime in the east and sought a better political environment for political stability and the establishment of Shu-Han regime.
In addition, in the battle, Zhuge Liang often bears the heavy responsibility of consolidating the rear, which can also show Zhuge Liang's extraordinary ability to handle government affairs. After Chengdu was pacified, Zhuge Liang served as a strategist and general, in charge of the affairs of the left general's office. Later, Liu Bei went out to fight, and Zhuge Liang was often allowed to stay in Chengdu to supplement the grain, grass and soldiers ahead.
When Liu Bei died of illness in Baidicheng, Shu Han suffered heavy losses, and the Shu Han regime was indeed in jeopardy at this time. Zhuge Liang not only did not let Shu Han decline, but gradually recovered and once again had the strength to go abroad, which had to be admired. At this time, Zhuge Liang monopolized the power of Shu Han, so he was able to achieve such achievements, which may also be the reason why Liu Bei died.
