Tension between Liu Bei and Sun Quan

After the great battle at the Red Cliff, Eastern Wu and Liu Bei vied for control of Jingzhou. Zhou Yu led the troops of Eastern Wu to attack Jingzhou and gained a victory, but eventually Jingzhou ended up in Liu Bei’s hands, as Zhuge Liang had advised Liu Bei to seize Jingzhou while Zhou Yu and Cao Cao’s forces were at war. Zhou Yu was extremely unhappy and reported the matter to Sun Quan. Sun Quan dispatched Lu Su to Jingzhou to negotiate with Liu Bei for Jingzhou. Again and again, Liu Bei refused to hand over Jingzhou to Eastern Wu. Sun Quan had no choice but to use new strategies suggested by Zhou Yu to take Jingzhou. One of these was the Beauty Scheme, in which Sun Quan lured Liu Bei to Jiangdong (where he intended to hold Liu Bei hostage in exchange for Jingzhou) by pretending to betroth his younger sister, Lady Sun to Liu Bei. However, Zhuge Liang outwitted Zhou Yu, and Liu Bei returned to Jingzhou safely with his new wife. Zhou Yu tried and failed repeatedly to take Jingzhou. After being infuriated by Zhuge Liang twice, Zhou Yu eventually coughed out blood. The third time, he coughed out even more, and died unconscious.
