Happy, you will compare, when Cao Cao Yanzhou rebelled, there were only three cities left, but the main army was in Xuzhou at that time, as for Nanyang for Jiangling and other counties, only fools can do it, Liu Biao is such a big territory, still raise 100,000 soldiers and horses, and people also have the Yangtze River natural danger Jiangling important land, in the person said that Liu Bei was at his peak, but there is also a Yizhou, who is crazy to use Liu Biao + Liu Zhang for Yuan Shu? Whether it is Nanyang or Huainan, there is no natural danger to defend,
And Lu Meng, the family of the Three Kingdoms, said very clearly, Xuzhou and Huainan are not easy to defend, it is not as good as Liu Bei's three counties, as for Nanyang and Yizhou, they are even more different, not to mention most of Jingzhou and Yizhou, the importance of one southern county is worth his entire Huainan.
In the Three Kingdoms era, food was the most important, and Lu Bu fought with Cao Cao for Yanzhou, but in the end he was defeated because of insufficient food. Lu Bu and Yuan Shu also ended up quickly because of lack of food. Liu Bei went to Guangling and ran out of food, and became the only official in the official history of the Three Kingdoms. And the grain is in the hands of the local powerful warriors, how can the army raise soldiers if they have no money and food? Learn from Liu Beijun to eat each other? Or learn from Yuan Shujun to eat river mussels? If you can't be deeply bound to the local heroes, why do these warriors support you? Why did Tao Qian want to lure Liu Bei over, it wasn't the contradiction between the foreign Danyang people under his command and the local Chen Deng, Mizhu, and other families, and he couldn't suppress the contradictions, and wanted to come to a third party to balance the situation?
