At that time, Liu Bei's strength was not strong, and he was wandering around with his own army, just like, like duckweed on the river, with no fixed place to live. We all know an allusion that Zhao Yun killed Liu Bei's children seven times in Changbanpo, but he didn't have a chance to save Liu Bei's wife. But when Zhao Yun came back with Dou, he was brutally abandoned by Liu Bei.
And this thing about Zhang Fei was when Liu Bei occupied Xuzhou. He took in Lu Bu, who was shouted and beaten by everyone at that time. Unfortunately, Lu Bu is rebellious. Taking advantage of Liu Bei's weakness, he led troops to attack Xuzhou City. Seeing that the gap between the enemy and me was too big, Zhang Fei abandoned the city and fled, but he forgot to take his sister-in-law with him when he fled. So after seeing Liu Bei, I apologized directly. Guan Yu accused Zhang Fei of running away without his sister-in-law, which made Zhang Fei even more ashamed. In desperation, I drew my sword and wanted to commit suicide. It is in this situation that Liu Bei uttered these two famous words handed down from ancient times.
Nowadays, Taoyuan Sanjieyi has also been widely praised as a model of brotherhood, and these two famous sayings of Liu Bei have also been widely circulated by people today and become the mantra of brothers.
