Lu Su, whose name is Zijing, a native of Dongcheng County, Linhuai County, was an outstanding strategist and diplomat in the late Eastern Han Dynasty, and proposed the "couch pair" among the four major pairs in the late Han Dynasty for Sun Quan, and was also the direct contact and earliest initiator of the Sun-Liu Alliance.

【Belonging to Sun Quan】

Lu Su was co-opted by Yuan Shu earlier and appointed as the mayor of Dongcheng, but later Lu Su thought that Yuan Shu could not achieve great things, so he abandoned Yuan Shu and went south to join his friend Zhou Yu, and finally crossed the river with Zhou Yu to take Qu A, and met Sun Ce, Sun Ce also appreciated Lu Su at that time, but it happened that Lu Su's grandmother died at that time, and Lu Su went back to mourn, so he did not stay in Jiangdong.

After that, Lu Su was originally prepared to take refuge in Jianghuai Haojie Zheng Bao under the advice of his friend Liu Ziyang, Zhou Yu personally wrote to Lu Su after knowing it, recommending him to Sun Quan, Lu Su then changed his mind and went south to join Sun Quan, and put forward a "couch pair" for him, planning to unify the south of the Yangtze River, and then unify the Central Plains, and achieve the strategic goal of the emperor's great cause.

However, Lu Su also offended Zhang Zhao because of this, and was considered by Zhang Zhao to be not modest enough, but Sun Quan looked at Lu Su differently.

As an outstanding strategist, Lu Su was very sensitive to changes in the current situation, and after learning of Liu Biao's death, Lu Su immediately understood that the situation in Jingzhou might change, so he immediately asked to see Sun Quan, advised Sun Quan to unite Jingzhou against Cao Cao, and finally personally sent an envoy to Jingzhou.

However, Lu Su was still a step late, when he arrived in Nanjun, Liu Cong had already surrendered to Cao Cao, Lu Su had no choice but to turn to Liu Bei, persuade Liu Bei and Sun Quan to unite against Cao Cao, and then Lu Su returned to Jiangdong with Liu Bei's envoy Zhuge Liang.

At this time, Cao Cao wrote to Sun Quan, saying that he wanted to hunt in Jiangdong with Sun Quan, which means that after Cao Cao captured Jingzhou, it is likely that Jiangdong is the next target, although Jiangdong is not weak at that time, it is still not comparable with Cao Cao, plus after losing the geographical advantage of the Yangtze River, most people are not optimistic about the prospects of Jiangdong, Lu Su was one of the few main battle factions at that time, but he understood that it was difficult for him to reverse the overall situation alone, so he not only brought Zhuge Liang over, but also asked Sun Quan to transfer Zhou Yu back, In the end, under the persuasion of Lu Su himself, Zhuge Liang, Zhou Yu and others, Sun Quan made up his mind to unite with Liu Bei and fight Cao Cao to the end.

In the thirteenth year of Jian'an (208), Sun Quan took Zhou Yu as the commander, and Lu Su as the captain of the Praise Military Academy to help Zhou Yuyun give advice. Finally defeated Cao's army in Chibi.

After the end of the war, Lu Su returned first. Sun Quan gathered the generals and greeted him with great fanfare. Lu Su entered the hall to meet Sun Quan, Sun Quan got up to salute him, and said to him: "Zijing, I saddle and dismount to meet you, which is enough to commend your merits, right?" Lu Su took a few steps forward, shook his head and said, "No." When everyone heard this, they were all stunned. After Lu Su took his seat, he slowly raised his whip and said: "I hope that the Supreme Virtue will spread all over the world, encompass Kyushu, complete the great cause of the emperor, and then summon me in a soft-wheeled car, which can be regarded as honoring me." After Sun Quan heard this, he stroked his palms and laughed, and then relied more and more on Lu Su.

After the Battle of Jiangling, Liu Bei personally met with Sun Quan and asked for the governor of Jingzhou. Lü Fan and other generals persuaded Sun Quan to detain Liu Bei, and Zhou Yu was in the field, so he also said this. Wei Lusu considered the overall situation and persuaded Sun Quan to lend Jingzhou to Liu Bei, and use Sun and Liu to unite and resist Cao together. Sun Quan eventually agreed to Lu Su's claim. It is said that when Cao Cao heard the news that Sun Quan had lent Jingzhou to Liu Bei, he was writing a letter, and in shock, he put pen to paper.

[Substitute for Zhou Yu]

After Zhou Yu was critically ill, he said to Sun Quan: "Today, it is a chaotic and eventful time, which is exactly what I worry about day and night, and I hope that Your Majesty will think about what has not happened in advance, and then think of comfort and enjoyment." Now that he is right with Cao, Liu Bei is close to the public security, and the people near the border have not yet been attached, so they should use good generals to go to garrison Zhenfu. Lu Su's resourcefulness is good enough, and I ask him to be used to replace me. On the day of my death, there will be no care. ”

Sun Quan immediately appointed Lu Su as the captain of Fenwu to lead the army in place of Zhou Yu. Zhou Yu's more than 4,000 subordinates and Fengyi in four counties all belonged to Lusu. Sun Quan also appointed Cheng Pu to concurrently serve as the Taishou of Nanjun. Lu Su was stationed in Jiangling at first, and then moved down the river to Lukou, his prestige and kindness were greatly spread, and the number of soldiers increased to more than 10,000 people, so Sun Quan appointed him as the general of Hanchang Taishou and Bi General. In the nineteenth year of Jian'an (214), Lu Su followed Sun Quan to break through the city of Anhui and was promoted to the general of Hengjiang.

According to the "Biography of Jiang Biao", after Zhou Yu was critically ill, he left a letter to Sun Quan, saying: "I am an ordinary person, and I was specially loved by the rebellious general in the past, and entrusted me with something very important. So he assumed the role of Jianwei Zhonglang General, commanded the soldiers and horses, commanded the battle, and served and participated in the battle with all his heart. The plan first pacified the land of Bashu, and then occupied Xiangfan, relying on the power of the country (and the lord of Wu), he felt that the success of the cause seemed to be in the palm of his hand.

Later, because I didn't pay attention, I got a sudden illness halfway, and a few days ago, I was treated and recuperated, but the disease was getting worse day by day and not alleviating, and there must be death in life, and people's life spans are long and short, which is really not worth lamenting. It's just that the ambition of the resentful life has not been displayed and practiced, and it can no longer be taught and sent by you. Now Cao Cao is dominant in the Central Plains, the territory has not been calm, Liu Bei lives in Jingzhou, it is really like raising a tiger for trouble, and the things in the world do not know how to end, this is really an eventful autumn, it is the time when the military generals are too busy to eat dinner on time, and it is the day when the lord thinks about anxiety. (On such days) Lu Su is a loyal and solemn person, he will not agree casually when things happen, he is the one who can replace me. When a man is dying, his words are kind and faithful, and if he could have said it to the lord, I would have died with regret. ”

Compared with Zhou Yu, Lu Su and Liu Bei, Zhuge Liang and others have more contact, and the relationship is more intimate, although Zhuge Liang proposed the Sun-Liu Alliance earlier than Lu Su, but the actual initiator of the Sun-Liu Alliance has to be said to be Lu Su, and it was Lu Su who led the bridge, and Liu Bei was able to form an alliance with Sun Quan.

Later, after Pang Tong was dismissed by Liu Bei, it was also recommended by Lu Su and Zhuge Liang that Liu Bei reused Pang Tong, and finally Pang Tong followed Liu Bei into Shu and pacified Yizhou. When Liu Bei borrowed Nanjun, he was even more strongly advocated by Lu Su, otherwise Sun Quan was likely to follow the advice of Zhou Yu, Lu Fan and others at that time and directly imprison Liu Bei, and it is difficult to say what will happen later.

Lu Su can be said to be a representative of the pro-Liu faction in the Sun Quan group, as one of the core generals under Sun Quan, Lu Su has a decisive influence, and his influence on the Sun-Liu alliance is also very great. At that time, in order to take into account the overall situation, Lu Su always appeased both sides with a friendly attitude.

However, this does not mean that Lu Su will give up the core interests of Jiangdong to Liu Bei, when it was time to fight, Lu Su did not have the slightest softness, and Lu Su's attitude was quite tough when he went to the meeting alone.
