As for the three monarchs, the comprehensive ability is definitely the best of Cao Cao, and the ruling power (divided into subordinates, troops and civilians) is basically Cao Cao. Sun Quan led his troops to a crushing defeat, and there were also cases where his subordinates refused to obey, so his dominance was definitely the lowest. Compare the remaining two at the same time:
1, subordinate dominance: Cao Cao's core soldiers did not waver when Lu Bu attacked Chongzhou, and some of his subordinates had contacts when Yuan Shao confronted powerful enemies; When Liu Bei was in the middle of the Central Plains, his subordinates still followed him faithfully, and his appeal was growing. At first glance, Liu Bei is slightly superior to Cao Cao, but in fact, Liu Bei is slightly inferior to Cao Cao. The first example shows that Cao Cao's middle and upper subordinates have high loyalty, and the second example is human nature, but I think most of them are middle and lower officials, and Liu Bei's men are loyal to him, but we can find that his men are basically unrelated, such as Zhang Guan, sworn brothers, Mi Zhu, in-laws, Jian Yong and fellow villagers. Few have nothing to do with this, which shows that Liu Bei's subordinates are slightly inferior in dominance.
2, the military superiority, this is also related to military commanders, but basically it can be seen that Cao Cao is stronger, and many princes have been defeated by Cao Cao.
3, the civilian rule, this is not comparable, but it can be said that Liu Bei's appeal is the strongest, but when Cao Cao hit Jingzhou, Liu Bei abducted many people, but did not bring much and killed a lot. Cao Cao surrendered 300,000 yellow towels and made good arrangements. Moreover, most of Liu Bei's followers were places that Cao Cao had not conquered, and the people were confused by the Han Dynasty. Or who is calling at the intersection and who is the surname. It can be seen that both sides of civilian rule are similar.
The most important thing is that Liu Bei has the name of Han clan, and Cao Cao has the name of Han thief. In this case, Cao Cao is slightly better than Liu Bei, which fundamentally shows that Cao Cao has the strongest ruling power.
