In Liu Huangshu,

After Battle of Red Cliffs, the seven counties of Jingzhou contested by military strategists were divided among Liu Bei, Cao Cao and Sun Quan. Cao Cao occupied Nanyang County, the largest county in the north of Jingzhou, Sun Quan got Jiangxia County and Nanjun County, and Liu Bei got four counties in the south of Jingzhou (Changsha, Lingling, Guiyang and Wuling). Liu Bei's garrison is not conducive to development. He borrowed South County of Jingzhou from Sun Quan twice. Lu Su persuaded Sun Quan to lend Nanjun to Liu Bei temporarily, so Liu Bei had five counties in Jingzhou (Nanjun, Changsha, Lingling, Guiyang and Wuling), resisted Cao Cao in the north and Sun Quan in the east, won Yizhou (now Sichuan) and established Han Shu's foundation industry. Later, after Liu Bei got Shuchuan, he returned Changsha and Guiyang counties to Sun Quan, which was equivalent to returning Nanjun. However, due to the influence of the Romance of the Three Kingdoms, there is still a saying that "Liu Bei borrows Jingzhou-never pays it back".
