Zhou Yu
At the time, Zhou Yu was in Poyang County so Lu Su advised Sun Quan to quickly summon Zhou Yu back to discuss their plans on how to counter Cao Cao's impending invasion. When Zhou Yu returned, he also urged Sun Quan to resist Cao Cao. This resulted in Sun Quan arriving at his final decision to go to war with Cao Cao. Sun Quan put Zhou Yu in command of his military forces and appointed Lu Su as Colonel Who Praises the Army () to assist Zhou Yu in formulating the battle plan.
