Why did Liu Bei hate Lu Bu the most in history?

Because Lyu3 bu4 was too ungrateful, he only cared about interests, and he once set a plot for Liu Bei, so that the foundation that Liu Bei finally established was destroyed at once. Liu Bei naturally hates Lu Bu.

First, I kindly took in Lu Bu. I didn't expect the farmer and snake Liu Bei to be generous. At that time, Lu Bu was armed to the teeth and fought for power and profit with Cao Cao, but he did not expect to fail. After the failure, Lu Bu had to come to Xuzhou to take refuge in Liu Bei. Liu Bei thought that Lu Bu was a great hero in killing Dong Zhuo, so he kindly took Lu Bu in. At that time, the two were brother and sister, and they looked good. Unfortunately, when Yuan Shu tempted Lu Bu with interests, Lu Bu immediately betrayed Liu Bei. Liu Bei was suddenly hit, and even his family was captured. So Liu Bei was defeated by Yuan Shu and had to flee to Haixi. During that journey, Liu Bei's soldiers were hungry and cold, and many people starved to death on the way. The ending is very sad.

Second, the ungrateful Lu Bu and Liu Bei are homeless. When they really can't support it, they can only bow their heads like Lu Bu. After all, their family and subordinates are controlled by Lu Bu. And lyu3 bu4 was fooled by Yuan Shu. He didn't get the food he deserved. Seeing that Liu Bei is willing to make up, he naturally looks like two brothers. However, Liu Bei was badly hurt by Lu Bu, and even his lair was gone. Naturally, he hates Lu Bu. All his soldiers were indirectly killed by this traitor, and Liu Bei really wanted to kill Lu Bu at that time.

Tell Cao Cao the truth of Lu Bu's final death, so Cao Cao hesitated to do with Lu Bu at that time. Although he knew this man was ungrateful, Lu Bu was indeed a military genius. Cao Cao also felt guilty, and Liu Bei spoke his mind at this time. Although it would arouse Cao Cao's suspicion, Liu Bei felt that it was now or never, and he would never come again. Because of this, Cao Cao made up his mind that Lu Bu was killed in the White Gate Tower.
