Zhang Fei is a fierce general in the "Romance of the Three Kingdoms", and his appearance is very powerful - leopard head ring eyes, swallow jaw tiger whiskers, sound like giant thunder, momentum like galloping horses. Zhang Fei's personality is very strong, he likes to drink alcohol on weekdays, he was the boss of killing pigs and selling wine in his early years, and he developed this habit.

After following Liu Bei, he was still just drinking wine. This person also has a problem, that is, when he is drunk or in a bad mood, he will find the soldier's stubble to whip the soldier, so everyone is very afraid of this person.
Liu Bei also advised him not to drink alcohol, not to beat people when he drank, and not to continue to stay around those who had been beaten, but Zhang Fei did not listen to persuasion, so Zhang Fei was finally killed by Fan Jiang and Zhang Da.
When Fan Jiang and Zhang Da killed Zhang Fei, it was when Liu Bei was preparing to raise an army to attack Wu in order to avenge Guan Yu's killing. Zhang Fei ordered his troops to prepare white armor and white armor within three days and hang up filial piety to Wu.
The next day, Zhang Fei's last generals, Fan Jiang and Zhang Dalai, reported that they could not handle the white armor in three days, and hoped to spare time. Zhang Fei was furious and tied the two men to a tree and beat them fifty times each with a whip, hitting them with blood in their mouths. Then Zhang Fei pointed at the two men and said, "Tomorrow we must do a good job, otherwise we will kill you."
These two people knew that tomorrow would definitely not be able to do it, only one death, rather than being killed, it was better to kill people, so they took advantage of Zhang Fei's drunkenness and sneaked into the tent to kill Zhang Fei.
Judging from Zhang Fei's consistent behavior, he often whipped the soldiers, and these soldiers and the people under the tent were very afraid of Zhang Fei, and most of these people must have been beaten by Zhang Fei, so it was difficult to ensure that everyone did not hate him.
Zhang Fei was already very famous for whipping the soldiers, and as early as when he captured Liu Dai, Zhang Fei used the hand of the whipping soldiers to make a bitter plan and caught Liu Dai. At that time, the body of the pawn was seriously injured, which was Zhang Fei's consistent style, not just for the purpose of using bitter meat.
Before that, Zhang Fei also forced Cao Bao to drink, cao bao did not drink was beaten by Zhang Fei, Cao Bao and Lü Buli yingwai jointly took Xuzhou. It can be seen that the harm of Zhang Fei's drinking was great, and at that time, the harm of Zhang Fei's whipping of the soldiers had not yet been fully exposed, but the hidden dangers had already occurred.
Besides, after Guan Yu's death, Zhang Fei was in an extremely bad mood, often whipping the soldiers, and even some were beaten to death. In ancient times, soldiers were father and son soldiers, brother soldiers and the like, these soldiers often did not come out alone to become soldiers, most of them were several relatives to become soldiers, even if they were alone as soldiers, it was difficult to guarantee that there was no good friend. Therefore, these people were beaten or even killed, which created conditions for Fan Jiang and Zhang Da to assassinate Zhang Fei.
Fan Jiang and Zhang Da were the last generals under Zhang Fei's tent, so why did they dare to ask for a grace period? Is it because you don't understand the situation—Zhang Fei's violent temper, or are you being directed by others? Someone has doubts about the big tent guard under Zhang Fei's tent? It is estimated that Zhang Fei's temper is not good, there are only some last generals under the account, and the general guards have left him.
In the case that there was no general under Zhang Fei's tent, and the soldiers around him were beaten to the bone, Fan Jiang and Zhang Da entered Zhang Fei's big tent without any risk, everyone hoped that Zhang Fei would die early, and once Zhang Fei died, he would not have to build white armor for three days, and no one would whip them when they were drunk or in a bad mood.
Therefore, the guards guarding Zhang Fei's big tent were useless, so Fan Jiang and Zhang Da could enter Zhang Fei's big tent without hindrance and go straight to his bed, and then assassinate him.
Zhang Fei's death, his character, his way of acting, is irreparable. Zhang Fei went to see Liu Bei after learning that Guan Yu had been killed, and before returning to the army, Liu Bei also told him not to flogg the soldiers, but he did not listen at all, so there was this senseless disaster.
