Liu Bei's political means can start with "recognizing his uncle", which is the cornerstone of his success. When he was in Jingzhou, he won popular support from local tyrants (such as Yi Ji and Ma Liang). The most important thing is that he ate Liu Qi (the most powerful heir in Jingzhou) as soon as he started, which aroused the vigilance of Cai's army. So he has the confidence to fight against Cao Cao, unite with Sun Quan and win Battle of Red Cliffs. It's easier to get into Sichuan. Liu Zhang was weak (referring to the warlord brought by Yizhou Group and Ada's father and son restraining each other), and Xuande quickly wooed the indigenous groups and directly threatened Liu Zhang (causing them to turn against each other).
After Liu Bei won Liu Zhang, he quickly became the king of Hanzhong, and the title of "king" was second only to that of "emperor", which further won the support of Jingzhou Army who followed him, Liu Shijun who defected to him and local warlords in Yizhou, and finally made him an emperor.
Liu Bei's success is not accidental but inevitable, not by tricks, but by wise political means. I think Kong Mingtai will usurp the throne. First, he is similar to Cao Cao, and the son of heaven is a shield. If you seize power rashly, after all, there will be a lot of trouble to clean up and foreign enemies will invade. During the second Three Kingdoms period, warlords scuffled, and the loyalty of the army to Kong Ming was mainly due to the late emperor. Therefore, if Kong Ming doesn't do it, he will basically not succeed. Kong Ming has always been cautious and loyal to Liu Bei, and certainly will not usurp the throne. According to the time, Liu Beigang died without strength (although it was already the prime minister who ordered Yizhou to shepherd, and the relieving was badly hurt); Later, he became an absolute monarch, and there was no need to usurp the throne, which made him notorious. Don't be a gentleman's belly with the heart of a villain. Kong Ming will certainly not usurp the throne, but it does not mean that Kong Ming will not be in power after Liu Bei's death. To equate taking power with usurping the throne can only say that your heart is too dirty.
