 Around 202, the warlord Cao Cao, who controlled the Han central government, demanded that Sun Quan send one of his sons to the imperial capital Xu (許; present-day Xuchang, Henan) as a hostage so as to secure Sun's allegiance towards him.When Sun Quan gathered his subjects to discuss the issue, they could not arrive at a conclusion.Personally, Sun Quan was not in favour of yielding to Cao Cao's demand, so he had another meeting with only his mother and Zhou Yu.
