Zhang Fei was born in a well-off aristocratic family and received a good education since childhood, which is just the opposite of Zhang Fei born in the novel. The novel is just to create a headstrong image and arrange a headstrong background for Zhang Fei.
There are not many records about Zhang Fei's achievements in his life. First of all, the most remarkable thing is that Changbanpo drank Cao Cao back. At that time, Liu Bei fled, and Cao Cao chased after him, and he was about to catch up. Liu Bei ordered Zhang Fei to lead an army to stop Cao Cao. So Zhang Fei took a group of soldiers and horses with only 20 people and kept at a pass, which was Dangyang Bridge.
When Cao Cao's soldiers and horses chased after the bridge, Zhang Fei shouted, "I'm Zhang Yide from Hebei. Who dares to fight to the death!" Cao Jun was afraid of Zhang Fei's army, but no one dared to fight. This harmony also laid the image of Zhang Fei as a brave man in the Three Kingdoms. But also frequently borrowed by various novels about the Three Kingdoms.
Secondly, Yan Yan was greatly hindered when Liu Bei competed for Xichuan, and Zhang Fei was ordered to go deep into Xichuan rescue. Yan Yan stopped him when he passed Jiangzhou. Zhang Fei was furious, and after some fighting, he easily won Yan Yan. Before beheading, Yan Yan said, "Only kill the generals who died in battle, not the generals who surrendered." Zhang Fei was very moved, so he let Yan Yan go and treated him as a distinguished guest. This behavior laid a righteous image for Zhang Fei.
Generally speaking, although Zhang Fei's achievements in his life are not as great as those of other famous soldiers in the Three Kingdoms, his image as a brave man is undeniable. Later generations thought that Zhang Fei was a fool only because he was influenced by novels.
