== The Event of Fan Castle == 

 Sun Quan had long for the return of the Jing 
 Province which Guan Yu guarded. It is true 
 that the Wu ruler did break the alliance of the 
 Wu and Shu treaty; however, the only reason why 
 Sun Quan sent Lu Meng to attack Jing is because 
 (If you read over the battle of Chi Bi and the 
 events leading up to Guan Yu's assault on Fan 
 Castle.) Liu Bei with Zhuge Liang's help manage 
 to take over the Jing Province right when Zhou Yu, 
 Commander-In-Chief, manage to send Cao Ren fleeing 
 from the Nanjun territory. (Correct me if I'm wrong.) 

 After Jing was still in control of Liu Bei's rule for 
 quite some time, Sun Quan was still ever so upset that 
 Liu Bei would not return the province even after Zhou Yu 
 with Zhuge Liang's aid sent Cao Cao's forces back to 
 Xu Chang. More or less, Sun Quan had only wanted Jing 
 back, but due to Zhuge Liang's deft speaking and ability 
 to understand people, the kingdom of Wu would had never 
 gotten back Jing had Lu Meng and Lu Xun not decided to 
 attack Guan Yu from behind.
