They are: Zhuge Liang, Zhao Zilong, Guan Yunchang and Zhang Fei.
1. Zhuge Liang
In his early years, he followed his uncle Zhuge Xuan to Jingzhou. After Zhuge Xuan died, Zhuge Liang lived in seclusion in Longzhong, Xiangyang. Later, Liu Bei visited the thatched cottage three times to invite Zhuge Liang, and joined forces with Sun Yat-sen to fight against Cao Cao, and defeated Cao's army in the Battle of Chibi. It formed a tripartite power among the Three Kingdoms and captured Jingzhou. In the 16th year of Jian'an (211), Yizhou was captured. Then he defeated Cao Jun and captured Hanzhong. In the first year of Shu Zhangwu (221), Liu Bei established the Shu Han regime in Chengdu, and Zhuge Liang was appointed prime minister to preside over the government. Liu Chan, the empress of Shu, succeeded to the throne, and Zhuge Liang was granted the title of Marquis of Wuxiang and led the shepherd of Yizhou.
Be diligent and prudent, handle all political affairs personally, and strictly enforce rewards and punishments; alliance with Soochow to improve relations with all ethnic groups in the southwest; implement the policy of farming and strengthen war preparations. Six Northern Expeditions to the Central Plains were carried out, but most of them used food to achieve no success. He eventually became ill due to overwork and died of illness in Wuzhangyuan (now Qishan, Baoji, Shaanxi) in the 12th year of Jianxing Shu (234) at the age of 54. Liu Chan posthumously named him the Marquis of Zhongwu, and later generations often addressed him as Marquis of Wu. The Eastern Jin Dynasty regime named him King Wuxing because of his military prowess.
Zhuge Liang's representative works of prose include "The Master's Guide" and "The Book of Commandments". He invented the wooden cow and flowing horse, the Kongming lantern, etc., and modified the repeating crossbow, called the Zhuge repeating crossbow, which can fire ten arrows with one crossbow. Zhuge Liang "dedicated his life to death" and was a representative figure of loyal ministers and wise men in traditional Chinese culture.
2. Zhao Zilong
Zhao Zilong’s full name is Zhao Yun. At the end of the Han Dynasty, when the warlords were fighting, Zhao Yun was elected by his county and led Yi Cong to join the White Horse General Gongsun Zan. During this period, he met Liu Bei, a relative of the Han Dynasty, but soon after, Zhao Yun left because of the death of his brother. About seven years after Zhao Yun left Gongsun Zan, he met Liu Bei in Yecheng and followed Liu Bei from then on.
Zhao Yun has followed Liu Bei for nearly thirty years. He has participated in the Battle of Bowangpo, the Battle of Changbanpo, and the Battle of Jiangnan. He has personally commanded the Battle of Ruchuan, the Battle of Han River, and the Battle of Jigu. All achieved very good results. In addition to fighting everywhere, Zhao Yun also successively served as the governor of Guiyang as a partial general, as the governor of Guiyang as the general of the Liuying army, as the general of the Yi army as the governor of Jiangzhou.
In addition, Zhao Yun cited the story of Huo Qubing to persuade Liu Bei to return the fields and houses to the people when he was pacifying Yizhou. He also advised Liu Bei not to attack Wu after Guan Yu and Zhang Fei were killed. He was praised as a minister by later generations. The outstanding Confucian general was even considered a perfect figure during the Three Kingdoms period.
3. Guan Yunchang
Guan Yu's original name is Changsheng, but later he changed his name to Yunchang. In his early years, he fled his hometown to Zhuojun, Youzhou (now Zhuozhou City, Hebei Province) for committing a crime.
In the first year of Zhongping (184), Liu Bei, a clan member of the Han Dynasty, organized a volunteer army in Zhuoxian County to participate in the war to exterminate the Yellow Turban Army. Guan Yu and Zhang Fei were among them. After Liu Bei held many official positions, he defected to his former classmate Gongsun Zan and was named Prime Minister of Pingyuan. He appointed Guan Yu and Zhang Fei as commanders of other departments and unified the divisions. The three of them were like brothers and often slept in the same bed together. When Liu Bei sat down, Guan and Zhang spared no effort to guard him.
4. Zhang Fei
Because of his extraordinary bravery, he and Guan Yu are called "the enemy of ten thousand people". When the Yellow Turban Uprising broke out in 184, Liu Bei organized a volunteer army in Zhuoxian County to participate in the war to exterminate the Yellow Turban Army. Zhang Fei joined Guan Yu and followed Liu Bei around. In 197, after Cao Cao attacked Lu Bu and Lu Bu was defeated, Zhang Fei was appointed Zhonglang General.
In 200 AD, Liu Bei's leadership was revealed, and he led Guan Yu and Zhang Fei to escape and killed Pi Taishou's chariot. Liu Bei was defeated, Guan Yu was captured, and Liu Bei and Zhang Fei defected to Yuan Shao. When Liu Bei was defeated at Changbanpo in 208, Zhang Fei only led 20 cavalry to defeat him, and no one from Cao's army dared to approach.
Extended information:
Liu Bei is the representative of "benevolence", Guan Yu is the representative of "righteousness", Zhang Fei is the representative of "brave", Zhuge Liang is the representative of "wisdom", Zhao Yun is the representative of "loyalty" and so on. Liu Bei is the central character in the novel and the embodiment of "benevolence" in the Chinese cultural spirit. When Liu Bei is introduced in the first chapter of the novel, it is said: This man was "seven feet five inches tall, with ears hanging down from his shoulders, hands above his knees, eyes that could focus on his ears, a face like a crown of jade, and lips painted with vermilion."
Later, he "stepped down from the yellow-maned horse and held a double sword in his hands", thus forming the overall image of Liu Bei in the novel: the work not only depicts Liu Bei's ambition and respect for himself and others through a large number of specific stories and character evaluations He Chengfu has deep character traits, and the most important thing is to exaggerate Liu Bei's characteristics of generosity and benevolence: the author of "The Romance of the Three Kingdoms" created the character of Liu Bei as a model of "benevolence", and "benevolence" is Liu Bei's character The foundation of Liu Bei is the embodiment of "benevolence" in traditional Chinese culture and the personification of "benevolence".
