Lu Xun has not only outstanding military ability, but also excellent political aspects in history. Although he was nominally only a one-year prime minister, he had actually begun to participate in political affairs to a large extent after the Battle of Yiling, and Sun Quan discussed almost everything.

【Political Qualifications】

In the eighth year of Jian'an (203), Lu Xun was twenty-one years old and began to serve in the shogunate of Sun Quan, successively serving in the East Cao Lingshi and West Cao Lingshi, and served as the governor of Tuntian in Haichang County, and was also in charge of the county's government affairs. Later, Lu Xun changed from politics to the army, mainly participating in military tasks.

In the second year of Huangwu (222), Lu Xun defeated Liu Bei in Yiling, began to serve as the pastor of Jingzhou, and began to be in charge of Jingzhou affairs. After Liu Chan of Shu Han succeeded to the throne and Zhuge Liang took power, Sun Quan ordered Lu Xun to correspond with Zhuge Liang regarding the relationship between Fan Wu and Shu, and engraved his own jade seal and placed it in Lu Xun's residence. Every time Sun Quan wrote a letter with Liu Chan and Zhuge Liang, he first asked Lu Xun for his opinion, and the documents given to Shu were also shown to Lu Xun first. It can be seen that Sun Quan trusted Lu Xun at that time.

In the fifth year of Huangwu (226), Lu Xun hoped that the generals would open up the farmland to increase grain and grass. Sun Quan not only agreed, but also took the lead in farming. In October of the same year, Lu Xun also went to the table to persuade Sun Quan to show kindness, reduce the punishment, relax the collection of land taxes, and stop the collection of household taxes.

In the first year of Huanglong (229), Sun Quan was proclaimed emperor, with Lu Xun as the general, and in the same year, Sun Quan toured Jianye, leaving the crown prince Sun Deng, the prince and Shangshu Jiuguan in Wuchang, and recruited Lu Xun as a guardian to assist the prince in Wuchang and lead the palace affairs left in Wuchang. He was also in charge of the affairs of Jingzhou and Yangzhou Yuzhang and other three counties, and presided over the military affairs in the western part of Wu, which was equivalent to Sun Quan handing over half of the power of Wu to Lu Xun.

At that time, the Marquis of Jianchang Sun Wei built a duck fighting fence in front of the hall, which was quite delicate and small, and Lu Xun said solemnly: "You should read the classics diligently, increase your new knowledge, what's the use of playing with these things?" Sun Shu immediately demolished the duck fighting pen. Sun Song (Sun Quan's nephew), the captain of the shooting voice, was the closest to Sun Quan in Gongzi, he did not discipline the army and indulged the soldiers, and Lu Xun punished his men with shaving their hair in front of him.

Xie Jing, a native of Nanyang, praised Liu Ji's theory of punishment before etiquette, and Lu Xun reprimanded Xie Jing and said: "Etiquette is superior to criminal punishment, which has long been proven by history, and Liu Ji's distortion of the teachings of the ancestors with trivial sophistries is completely wrong." Now that you are serving in the East Palace, you should follow benevolence and righteousness to show good words, and there is no need to talk about things like Liu Zhi. ”

In the sixth year of Jiahe (237), Sun Quan issued an edict ordering the ministers to discuss legislation on funeral, and Prime Minister Gu Yongzuo requested that illegal funeral should be punished with death. After that, Wuxian County ordered Meng Zong to go home for his mother's funeral in violation of the law, and then detained himself in Wuchang to wait for punishment. Lu Xun explained to Sun Quan Meng Zong's usual actions, and took the opportunity to intercede for Meng Zong, so Sun Quan reduced Meng Zong's sentence by one class, and stated that he would not take the next example, so the illegal funeral was extinct.

At that time, Xie Yuan, Xie Wei and others each stated the current matters that should be done, and planned to change some political measures and do some beneficial things for the country, and Sun Quan handed over the matter to Lu Xun for approval. Lu Xun believes that the people should come first in everything, and the country should be strong when the people are rich, and should not just expect to change some policies.

In the first month of the seventh year of Chiwu (244), Sun Quan appointed Lu Xun as prime minister after the death of his predecessor Gu Yong. The edict said: "I am a person without virtue, I have accepted the mandate of heaven and ascended to the throne, the world has not yet been unified, and the traitors are filling the roads, and I am afraid day and night, and I cannot take care of rest." However, you are gifted and intelligent, and you have remarkable virtues, serving as a general and assisting the court to eliminate chaos. Those who have made great achievements in the world should receive great glory, and those who have both civil and military talents must take on the important responsibility of social work. In the past, Yi Yin made Shang Tang prosperous, and Lu Shang assisted the Western Zhou Dynasty, but now the major affairs inside and outside the court are really on your shoulders. Now with you as the prime minister, I will send the envoy to hold the festival Taichang Fu often to grant you a seal ribbon. Thou shalt carry forward thy noble virtues, thou shalt accomplish good deeds, thou shalt obey the king's commands, and thou shalt pacify the four directions. Alack! In charge of the three public ministries and the discipline of the ministers and hundreds of officials, can you not be serious? Do your best! The positions you originally held as the pastor of Jingzhou, the protector of the right capital and the left-behind guard of Wuchang are still the same. ”

【Advice to Sun Quan】

Lu Xun advised Sun Quan in Yizhou, Liaodong, Lu Yi and the Second Palace, but unfortunately Sun Quan did not fully listen to it, and later Sun Quan regretted these things.

In the second year of Huanglong (230), Sun Quan wanted to send troops to take Yizhou (present-day Taiwan) and other places, and he asked Lu Xun's opinion. Lu Xun thinks that it is not necessary, and the book thinks that such a thing is not beneficial. Sun Quan still sent an army to conquer Yizhou, but the army suffered heavy losses due to the plague, and only got a few thousand natives, and the gains outweighed the losses, and he regretted it greatly.

In the second year of Jiahe (233), Sun Yuan, the prince of Liaodong, proclaimed himself a minister to Wu Fengbiao, and Sun Quan was happy. In March, Sun Quan sent envoys with gold treasures and treasures, led more than 10,000 soldiers to Liaodong, and named Sun Yuan as the king of Yan. As a result, Gongsun Yuan believed that Wu was far away and difficult to rely on for a long time, so he killed the envoy and annexed his troops. In December, Wei worshiped Gongsun Yuan as the Great Sima and named the Duke of Lelang. When Sun Quan heard this, he was furious and wanted to personally lead his troops to conscript. Lu Xun was blocked from writing, Sun Quan listened to his opinion, and later he conducted self-reflection because of his previous arbitrary actions.

In the first year of Chiwu (238), the crime of Lu Yi, who was a school official, was exposed and executed. He used to pamper power, divide monarchs and ministers, act as a prestige, threaten revenge, and his methods were very cruel. Lu Xun and Pan Jun, who were far away in Wuchang, were worried about this matter, and they often brought it to the point of tears. Sun Quan blamed himself deeply after killing Lu Yi, and also sent Yuan Li, a Zhongshulang, to apologize to everyone.

In May of the fourth year of Chiwu (241), Sun Deng, the crown prince of Wu, died. In the following year, Sun Quan took the third son and son He as the crown prince, and the fourth son and grandson Ba as the king of Lu, and the party struggle in Southern Lu began. At first, Lu Xun was not ready to participate in it, but then things developed to the point where he could not sit idly by, so Lu Xun supported the prince as the prime minister and maintained the etiquette of the imperial court. In the dispute between the two palaces, Sun Quan took the opportunity to suppress the local clans in Jiangdong, and Lu Xun bore the brunt of the blame, and finally died in anger. Many years later, Sun Quan's resentment dissipated and he regretted not being at the beginning.

【Lu Xun's political ability】

Lu Xun does not have any obvious shortcomings in politics on the whole, it can be said that he is very stable and traditional, and he is actually stronger than Zhang Zhao in this regard.

In the dispute between the second palace, Lu Xun's performance has nothing to blame, it can be seen that Lu Xun was not ready to participate in Sun Quan's family affairs at the beginning, and also advised other ministers not to participate in it, in order to reduce the impact of the second palace infighting, but because of Sun Quan's connivance, things are getting bigger and bigger, and Lu Xun has no choice but to participate in it, and it is natural for him to support the crown prince Sun He, who has no obvious fault, and the fault is that Sun Quan fainted in his later years and killed Lu Xun.
