After Liu Bei went to Yizhou, Jingzhou was initially guarded by Guan Yu, Zhuge Liang, Zhang Fei, Zhao Yun and others, but as Liu Bei began to attack Liu Zhang, Zhuge Liang and others were transferred to Yizhou, and Jingzhou was handed over to Guan Yu to guard alone.

【Garrison in Jingzhou】

After the battle of Chibi and Jiangling, Liu Bei took advantage of the victory to occupy several counties in the south of the Yangtze River, and then worshiped the meritorious soldiers, appointed Guan Yu as the general of Xiangyang Taishou and Dangkou, and sent him to garrison Jiangbei, but at that time, the Xiangyang area was occupied by Cao Cao's general Lejin, so Guan Yu and Lejin had a period of confrontation here.

Later, Liu Bei went west to pacify Yizhou, transferred Zhuge Liang and others, and authorized Guan Yu to take charge of Jingzhou. At that time, Jingzhou was divided by three families, Jiangxia County Liu Bei, Sun Quan and Cao Cao all occupied a part, the four counties of Jingnan were owned by Liu Bei, the northern part of Nanjun had belonged to Cao Cao, and the southern part was lent to Liu Bei by Sun Quan, Guan Yu can be said to have controlled most of the territory of Jingzhou at that time.

Guan Yu heard that Ma Chao had surrendered to Liu Bei, and he didn't know Ma Chao in the past, so he wrote to Zhuge Liang and asked who Ma Chao's martial arts talent could be compared with. Zhuge Liang knew that Guan Yu was arrogant, so he replied: "Ma Mengqi is both civil and military, brave and outstanding, worthy of a generation, is a figure like Yingbu and Peng Yue, can be on a par with Zhang Fei, but not as outstanding and outstanding as the beautiful bearded man." "Guan Yu has a beautiful long beard, so Zhuge Liang calls him a beautiful beard. After reading Zhuge Liang's reply, Guan Yu was very happy and handed it over to the guest staff for circulation.

According to the "Notes on the Book of Water", Guan Yu rebuilt Jiangling City at that time.

【Bone scraping and healing】

In the "Romance of the Three Kingdoms", Hansheng attacked Fancheng again after capturing and killing Pang De, but was shot in the right arm by a poisonous cold arrow, and the divine doctor Hua Tuo came to scrape the bones with a knife for him to remove the poison, and the people outside the tent were as pale as dirt, and Guan Yu still drank and ate meat, talked and laughed and played chess, and there was no pain at all.

There is indeed this thing in history, but it was not during Guan Yu's crusade against Xiangfan, and it was not Hua Tuo who treated Guan Yu.

Guan Yu was once shot by a stray arrow, and the arrow penetrated his left arm, and although the wound healed later, his arm bones often hurt in rainy weather. The doctor said: "The arrow is poisonous, and its poison has penetrated into the bone, and it needs to be re-operated on the arm to scrape off the toxin from the arm bone to completely get rid of the disease." Guan Yu immediately stretched out his arm and asked the doctor to treat him. At that time, Guan Yu was inviting the generals to drink and eat, and the knife on his arm was dripping with blood, flowing all over the plate below, but Guan Yu was cutting meat and drinking wine, talking and laughing with everyone.

【Xiangshui Demarcation】

In history, the beginning of the rupture between Liu Bei and Sun Quan was because of Yizhou. Earlier, Sun Quan intended to seize Jingzhou at the suggestion of Zhou Yu and others, but was blocked by Liu Bei, and after that, Liu Bei entered Yizhou, Sun Quan said: "The cunning captives dare to blackmail!" (How cunning can dare to play tricks!) ）”

In the twentieth year of Jian'an (215), Sun Quan thought that Liu Bei had occupied Yizhou and wanted to return to Jingzhou, but Liu Bei responded: "When you can wait for Liangzhou, I will give Jingzhou to you." Sun Quan said: "This is borrowing but not repaying, and using empty words to prevaricate and delay time." So he set up the Taishou of the three counties in the south of Jingzhou, and as a result, Guan Yu drove all these people away.

So Sun Quan was furious, so he sent Lü Meng to command Xian Yudan, Xu Zhong, Sun Gui and others to lead 20,000 troops to capture the three counties of Changsha, Lingling and Guiyang, and sent Lu Su to lead 10,000 horses to garrison Baqiu to defend Guan Yu. Sun Quan lived in Lukou and commanded and dispatched various armies. As soon as Lümeng's army arrived, the two counties of Changsha and Guiyang were all subjugated, and only Lingling Taishou Hao Pu was unwilling to surrender. It happened that Liu Bei came to the public security, sent Guan Yu to lead 30,000 troops into Yiyang, selected 5,000 elites to prepare to cross the river from the upstream, Wu General Gan Ning led 1,000 people to garrison, Guan Yu did not cross the river after learning about it, and camped on the other side of the river, this place was later called "Guan Yuse".

Sun Quan then recalled Lü Meng and others to return to aid Lusu, Lü Meng sent people to lure Hao Pu, Hao Pu surrendered to Eastern Wu, Lü Meng got the generals of the three counties, Taishou, led the troops to return to the east, and Sun Jiao, Pan Zhang merged with the Lusu army to advance together, and fought against Guan Yu in Yiyang.

For the sake of the overall situation, Lu Su invited Guan Yu to meet, and proposed that each of them arrange the soldiers and horses a hundred steps away, and only the generals would bring a single knife to the meeting. After Lu Su made a decision, his subordinate generals were afraid of something wrong and advised Lu Su not to take the danger lightly. Lu Su was not afraid, he said: "Today, we should make things clear." Liu Bei failed the country, and the rights and wrongs have not yet been decided. What can Guan Yu do? "Resolutely go to the meeting.

At the meeting, Lu Su accused Guan Yu several times: "We in Jiangdong sincerely lent you the land because you came from afar after the defeat and had no place to stand." Now that you have obtained Yizhou, since you don't mean to return Jingzhou, then I only ask you to return the three counties, and you still don't obey your orders. Before Lu Su's words fell, a general from Jingzhou said: "When it comes to land, only benevolent and virtuous people can occupy it, how can there be a reason for a family to occupy it forever!" Lu Su immediately shouted loudly, and his tone was stern. Guan Yu also stood up at this time, and said to the man: "These are naturally national affairs, what does he know!" He motioned with his eyes for the man to leave.

Although Guan Yu knew that his side was at a loss, he was not qualified to hand over the three counties to Dongwu, so the two sides insisted on their own words, and there was no result in a single knife meeting, and the situation was stalemate at that time, and war was about to break out.

But at this time, Cao Cao entered Zhang Lu in Hanzhong, the door of Yizhou was wide open, Liu Bei could no longer care about Jingzhou, so he quickly reconciled with Sun Quan, and sent an envoy to Sun Quan to seek peace, Sun Quan sent Zhuge Jin to pay a return visit, and the two countries re-established an alliance, and agreed to divide Jingzhou equally, that is, with Xiangshui as the boundary, Jiangxia County, Changsha County, and Guiyang County of Jingzhou belonged to Sun Quan, and Nanjun, Lingling County, and Wuling County of Jingzhou belonged to Liu Bei, which was the famous Xiangshui demarcation in the history of the Three Kingdoms. Three counties of Wuling County.

Historically, Jiangxia County originally belonged to Jingzhou and was controlled by Liu Biao, but later Sun Quan crusaded against Jiangxia many times, and finally killed Huang Zu, the then Jiangxia Taishou, thus seizing part of the territory of Jiangxia County; After Cao Cao went south to Jingzhou, Liu Cong surrendered, and Cao Cao took the opportunity to control part of the territory of Jiangxia County, and later appointed Wen Ping as the Taishou of Jiangxia County; After the death of Huang Zu, Liu Qi became the new Jiangxia Taishou, Liu Bei ran to Jiangxia and Liu Qi after the fiasco in Dangyang, Liu Qi was later recommended by Liu Bei as the new Jingzhou Assassin Shi, died soon after illness, and the Jiangxia territory he controlled was naturally controlled by Liu Bei.

Therefore, Liu Bei actually gave half of Jiangxia County plus Changsha County and Guiyang County to Sun Quan, as Sun Quan's loan to Jiangling (borrowing Nanjun) at that time.
