The slogan of launching the Yiling War turned out to be revenge for Guan Yu. Sending troops pays attention to fame, but Liu Bei's slogan cannot stand scrutiny. Although Cao Cao shouted the slogan "I would rather lose the world than lose me in the world". But I think Liu sophomore is the one who has achieved the ultimate in this slogan. The man abandoned his wife many times, and the incident of imperial edict wearing clothes broke out first. In a word, Lu Bu was accused of the White Gate Tower, and even the land he robbed belonged to his so-called Han clan. Therefore, personally, the slogan of cutting Wu is just an excuse. Zhuge Liang did not go out with the army in the battle of Yiling, and Liu Bei's war went smoothly from the beginning. Later, Lu Xun burned Liu Bei's 800-mile joint venture in the mountains with fire. Liu Bei fled in defeat and finally died in Baidicheng. Zhuge Liang came up with some tricks after the battle, but he didn't think Liu Bei would be so stupid. Wu Jun set fire to Liu Bei's stronghold, which was on the plain at that time. The fire came soon, and Liu Bei was a battalion of 800 Li. The Shu army could not react. I feel that the failure of the Yiling War was that Liu Beitai rashly ignored Zhuge Liang's words and insisted on waging war. In addition, Liu Bei played so smoothly in the early stage of the war that he felt that Soochow was not afraid enough, so that the Shu army camped 800 miles on the mountain without any barrier, only to be caught by Lu Xun.
