In contrast, the author first portrayed Zhang Fei as a savage in life. It may even make you look unreasonable. Let you naturally think that this is a strongman who does things without thinking. However, the author made a hint when he wrote Liu Bei's entry into Shu in the later period. First, the soldiers were divided into two roads, Zhuge Liang led the troops by water and Zhang Fei led the troops by Sichuan Road. With Zhang Fei as the commander-in-chief of an army, it can be seen that Zhang Fei has his own talent as a general, and he is not a brave and foolhardy man. As for Yan Yan's later explanation, it was proved in specific events.
So, on the whole, it can be said that it is more useful. The comparison before and after this book, and the comparison between Zhang Fei's daily life and marching and fighting make the description of this character more real.
