Liu Bei sat in Jingzhou, Wen was assisted by Wolong Fengyan, Wu was related to Zhang Zhaoyun, Huang Zhongweiyan, and Zhang Song presented the map of Xichuan, which was the time when Liu Bei was proud of the spring wind and showed his grand plans. Zhuge Liang took Zhang Zhao Yunzhen to guard Jingzhou, Pang Tong assisted Liu Bei with Wei Yan Huangzhong to take Xichuan, Liu Feng Mengda attacked Shangyong, forming an iron triangle of Xichuan, Jingzhou, and Shangyong, and could join forces with Wu and Wei, retreat to Shangyong, Xichuan against Cao Wei, and the east could rely on Jingzhou to resist Eastern Wu, really to wind the wind, to rain and rain.
Liu Bei's own talents around him were relatively withered, plus he could not make good use of them. So don't say that he dominates the world and defends the country and mountains is a problem. Liu Bei's White Emperor City was isolated. When Liu Bei was defeated at the Battle of Yiling. When retreating to the White Emperor City and returning to Chengdu without face. He wanted to entrust all the things behind him to Zhuge Liang. This is also described in the Romance of the Three Kingdoms. Allusions to the military and civilian Chen Xian.
Liu Bei hurriedly dispatched Zhuge Liang, Zhang Fei, and Zhao Yun into Shu. Later, after Jingzhou's air defense was weak, it was secretly attacked by Sun Quan, Lü Meng crossed the river in white, Guan Yu was embarrassed, and defeated Maicheng and was killed. Liu Bei ignored Zhao Yun. Zhuge Liang dissuaded, determined to take revenge, and launched the Battle of Yiling, which resulted in a disastrous defeat. This was Liu Bei's biggest failure. The elite of the Shu Kingdom was lost, and there was no longer any strength to win the Central Plains, becoming the weakest of the Three Kingdoms!
The actual situation of China's strong north and weak south during the Three Kingdoms period will not change because Wolong Fengchi was in Western Shu. Ancient China has always been the north annexed the south, this is because the north is stronger than the south in politics, economy, military, culture, science and technology, etc., China's center of gravity began to move south after the Wei and Jin Dynasties, while the southwest is even more underdeveloped. What "Kingdom of Heaven" only means that the land of the Sichuan Plain is relatively fertile, but other aspects are stunned.
