After the Battle of Chibi, Sun Liu Cao's three forces divided Jingzhou. (The administrative planning of Jingzhou was not static, such as Cao Cao's establishment of Xiangyang County, and the later Jingzhou area reached more than 20 counties.) For convenience, this article is based on the seven counties of Jingzhou at the end of the Eastern Han Dynasty. Regarding the division of Jingzhou by Sun Liu Cao's three forces at the Battle of Chibi, the general saying is that Liu Bei occupied the four counties of Jingnan (Changsha, Guiyang, Lingling, and Wuling) and the southern part of Nan Commandery (Jiangling), Cao Cao occupied Nanyang County and the northern part of Nan Commandery (Xiangyang), and Sun Quan occupied Jiangxia County. However, this statement is problematic, that is, the ownership of Jiangxia County.

After Cao Cao's defeat, in order to prevent Sun Liu's combined forces from taking advantage of the victory to attack Jingzhou, six generals were left to defend the rear. They are Le Jin of Zhenshou Xiangyang, Cao Ren of Zhenshou Jiangling, Man pet of Zhenshou Dangyang, Wenpin of Zhenshou Jiangxia, Xu Huang of Zhenshou Fancheng, and Li Tong of Zhenshou Runan.
Later, Zhou Yu captured Jiangling, Liu Bei captured the four counties of Jingnan, and Sun Quan lent Jiangling to Liu Bei, which was naturally no problem. The question is, who is Jiangxia County in the hands of at this time? There is no record of Sun Quan or Liu Bei seizing Jiangxia, so was Jiangxia County in Cao Cao's hands?
In 208 AD, Jiangxia Taishou Huangzu was killed in battle. At that time, Liu Biao of Jingzhou favored Lady Cai, and his eldest son Liu Qi, fearing persecution by the Cai clan, asked for the post of Jiang Xia Taishou to resist Sun Quan. Shortly after Liu Qi arrived in Jiangxia, Liu Biao died of illness and Cao Cao's army overwhelmed the territory. Liu Qi led the Jiang Xia army to meet Liu Bei at Xiakou and join Liu Bei's army, followed by the Battle of Chibi between Sun Liu Lianjun and Cao Jun in the Chibi-Xiakou area.
Before the Battle of Chibi, Cao Cao's army had already pushed northern Jiangxia and appointed Wen Ping as Jiangxia Taishou (江夏太守), zhenshou Jiangxia (江夏). That is to say, Cao Cao occupied half of Jiangxia County, but what about the other half of Jiangxia County? Before the Battle of Chibi, it was naturally in the hands of Liu Qi, the Taishou of Jiangxia. After the Battle of Chibi, Liu Bei made Liu Qi the Assassin of Jingzhou. Liu Qi was actually under Liu Bei's control. Therefore, after Liu Qi's death, the southern part of Jiangxia County should belong to Liu Bei. If this is the case, Jiangxia County should actually be divided between Cao Cao and Liu Bei, so why is there a claim that Jiangxia County is under the control of Sun Quan? This stemmed from a misunderstanding.
<h1 class="pgc-h-arrow-right" > Xiakou, who is in who's hands? </h1>
In the year that Jiangxia Taishou Huangzu died in battle, Sun Quan did indeed attack Jiangxia County's Zhixiakou, and when he learned that Liu Qi was going to Jiangxia, Sun Quan's army retreated from Xiakou, and Liu Qi was able to take more than 10,000 soldiers and horses to Xiakou, and this army soon became the capital of Liu Bei's army' comeback. In fact, Liu Qi retained most of Jiangxia County, but Sun Quan only captured a county in the eastern part of Jiangxia County.
Until 215 AD, Liu Bei and Sun Quan signed an agreement to demarcate the border in order to solve the problem of Jingzhou's ownership, that is, with Xiangshui as the boundary, the Nan Commandery, Lingling, and Wuling of Jingzhou belonged to Liu Bei, and the Jiangxia, Changsha, and Guiyang of Jingzhou belonged to Sun Quan. This officially determined The ownership of Jiangxia.

Therefore, the strict statement should be that Jiangxia was divided between Liu, Cao, and Sun forces, with Cao Cao occupying northern Jiangxia, Liu Bei occupying southern Jiangxia, and Sun Quan occupying a county in eastern Jiangxia. But there is also another possibility, that is, the western part of Jiangxia gave up to Liu Bei as a price when Liu Bei borrowed Jiangling. But this possibility is not high, because the Xiangshui Alliance deliberately mentioned that Jiangxia returned to Sun Quan, and if Jiangxia was already in Sun Quan's hands, then there was no need to deliberately mention it. Therefore, the Xiangshui Alliance mentioned Jiangxia County, which also confirmed the statement that the southern part of Jiangxia County was in Liu Bei's hands at that time. The attribution of Jiangxia County has always been vague, because both Sun and Liu deliberately avoided the record of this. But we can still deduce the most likely attribution of Jiangxia County.
