General Zhengxi was a senior military official position established in the Eastern Han Dynasty, and in a literal sense, he was mainly responsible for commanding the western soldiers, horses, and military generals, of whom those with great military achievements and high seniority would also be appointed as the general of Zhenxi. The three major groups of the Three Kingdoms period all continued the old system and set up the post of General of Zhengxi, but this position belonged to the higher-ranking heavy generals in the Cao Wei clique, while the Shu and Wu cliques belonged to the slightly lower rank of miscellaneous generals. Eight members of the Cao Wei clique held the post, and their duties were to lead the troops of Chang'an, and to command the soldiers, horses, and military operations in Yong and Liang prefectures.
First: Xiahou Yuan. Xiahou Yuan was a close vassal of Cao Cao's side and a fierce general in the early days of Cao Wei's clique, and had many military achievements in the early years of following Cao Cao in his conquests. After Xiahou Yuan followed Cao Cao in the sixteenth year of Jian'an (211 CE) in defeating Ma Chao and Han Sui in Weinan, he was ordered to garrison Chang'an. In the nineteenth year of Jian'an (214 AD), Xiahou Yuan led his troops to assist Yang Fu, Jiang Xu, and others in breaking up the rebels of Ma Chao and the Qiang and Qiang tribes, completely eliminating the threat in the Longyou region. At this point, Xiahou Yuan's name was Zhenyong, liang area, Qiang, Hu and other ethnic groups. The following year, after following Cao Cao to pacify Hanzhong, Xiahou Yuan was appointed as the general of Zhengxi and commanded the military forces of Yong and Liang Prefectures. In his fourth year on the throne, Xiahou Yuan was killed while engaging the Shu army in Hanzhong.
Second place: Zhang Gao. Zhang Hao fought bravely and strategically, and in his early years he was a general under Yuan Shao. During the Battle of Guandu, if Yuan Shao had adopted Zhang Gao's suggestion to rescue Wuchao, which was storing grain and grass, instead of sending troops to attack Cao Cao's base camp, it is estimated that the outcome of the Battle of Guandu would have been a different direction. Unfortunately, Yuan Shao not only did not accept Zhang Guo's suggestion, but instead listened to Guo Tu's rumors and wanted to punish Zhang Guo. In desperation, Zhang Gao had to surrender to Cao Cao.
After joining the Cao Wei Clique, Zhang Gaonan yu eastern Wu and Western Keshu Han had brilliant achievements. During the Battle of Guanzhong, Zhang Hao followed Xiahou Yuan for many military feats. After that, Zhang Gao came down to Hanzhong as a subordinate of Xiahou Yuan, and temporarily took over as the commander of the Cao Army in Hanzhong after Xiahou Yuan was killed, which made Liu Bei and Zhuge Liang very jealous. According to the "Table of Officials of the Three Kingdoms", in the first year of Taihe (227 AD), Zhang Gao was promoted to the rank of general of Zhengxi and followed the general Cao Zhen to resist Zhuge Liang's Northern Expedition. Zhang Hao was distinguished in battle during his tenure, and was later promoted to the rank of Cheqi general, and was eventually killed by a wrong order from Sima Yi.
Third place: Zhao Yu. Zhao Yu was a famous minister of the Cao Wei clique who had both Chinese rule and martial strategy, and since joining the Cao Wei clique in the second year of Jian'an (197 AD), he had a good performance in both local governance and unified military operations. In the first year of the reign (240 AD), Zhao Yu was moved from the general of Zhengshu to the general of Zhengxi, and commanded the military of Yong and Liang Prefectures, and soon after he was promoted to general of Hussars.
Fourth place: Xiahou Xuan. Xiahou Xuan was another member of the Cao clan and entered the career path in his early years. In the fourth year of the reign (243 CE), Xiahou Xuan was moved from the Zhonghu Army to the post of General of Zhenxi, commanding the military forces of the Yong and Liang regions. However, in the second year of Xiahou Xuan's reign, after the defeat of the Battle of Luogu, which he planned with his cousin Cao Shuang, he lost face in the army and was an unworthy mediocre general among the eight generals of Cao Wei.
Fifth place: Guo Huai. Guo Huai was a northwestern general in the middle of the Cao Wei dynasty, who fought against the Shu army for many years and had good achievements in both the local and military areas. In the first year of Jiaping (249 AD), after Xiahou Xuan's elevation, Guo Huai became the fifth general of the Cao Wei clique, commanding the military of Yong and Liang Prefectures, and after a year in office, he was promoted to the rank of General of CheQi.
Sixth place: Chen Tai. After Chen Tai was a meritorious warrior, his father was Chen Qun, the sikong of the Cao Wei clique. Chen Tai joined the Cao Wei clique in his early years with his father's merits, and successively served as a scattered horseman, a changshi, a guerrilla general, a zhenwei general, a general who protected the Xiongnu, and a thorn history of Yong and Yong prefectures. In the first ten years (249 AD), Chen Tai persuaded the general Cao Shuang to surrender, in order to gain the respect and trust of the Sima clan. In the second year of the Zhengyuan Dynasty (255 AD), Chen Tai moved to the post of general of Zhengxi, and falsely ruled the yong and Liang prefectures, and stepped down during the Ganlu period.
Seventh place: Deng Ai. Deng Ai is an all-rounder of the Cao Wei clique, and has become a famous general of the Cao Wei clique through unremitting efforts from a humble tunmin. Deng Ai made many achievements in the course of fighting the Shu army on the battlefield of the Western Front, and at the same time, he was also the first meritorious minister in the final battle to destroy Shu. In the second year of Ganlu (257 AD), Deng Ai was promoted to the rank of general of Zhenxi and commanded the military of the Longyou region.
Eighth place: Sima Wang. Sima Wang was a close vassal of the Sima clan, a cousin of Sima Yi, and the last general of the Cao Wei clique to conquer the west. Sima Wang joined the Cao Wei clique in his early years, successively serving as Taishou (太守), Diannong Zhonglang (典nong Zhonglang), and general of the Protector Army, and was promoted to general of Zhengxi during the Jingyuan Dynasty, holding the military positions of Yong and Liang'er prefectures. During Sima Wang's tenure, he suppressed the localities and rectified the defenses, successfully resisted Jiang Wei's Northern Expedition many times, and was recalled to serve in the dprk a few years later.
