Zhang Fei: The whole world says that Zhang Fei is a reckless person, but judging from the romance of The Three Kingdoms, Zhang Fei himself is not the kind of person whose muscles grow into his head. First of all, Changbanpo and Zhang Fei blocked Cao Jun alone, but because the bridge was finally demolished, Cao Cao saw the flaw. Secondly, Zhang's release of veterans also reflects a resourceful wind. Therefore, Zhang Fei is a more strategic military commander, but his vision is not long enough, which eventually leads to tragedy.
Wei Yan: Wei Yan doesn't explain much. Only one thing, if there is no so-called Feng Shui in this world, Wei Yan can only be regarded as a tragedy and will not be reused by Zhuge Liang. This can be seen from Zhuge Liang's many meritorious deeds when he captured Meng Huo, but they were not adopted by Zhuge Liang. There are also some historical reasons (when Wei Yan surrendered for the first time, because there was an anti-bone behind his head, Zhuge Liang immediately ordered it to be cut off).
Pang Tong: Feng Chu, son of Pang Tong, whose name is Wolong. His life's contribution is to skillfully offer a series of tricks to coordinate Zhuge Liang's acquisition of Xichuan. Pang Tong's personality is a bit odd. From his conversations with Sun Quan and Liu Bei, we can see that he is arrogant and narrow-minded. These characters led him to ignore Zhuge Liang's good words, enter Xichuan, and finally be shot.
Chu Xu: Chu Xu is considered a tiger idiot. Rumor has it that he and Dian Wei are the captains of Cao Cao's Guards. He is not a general, but he is brave and foolhardy (this is no exaggeration). It can be seen from his deeds of fighting against Ma Chao and being assassinated by Ma Chao that Chu Xu is brave, but he doesn't care about the overall situation. He is not a general, but he is a samurai and loyal.
