Poyang Lake is the site of Zhou Yu’s naval exercises when Sun Quan’s court seeks his counsel on whether to resist Cao Cao or surrender. In the account, the lake’s significance is strategic and political: it connects Zhou Yu’s military role to a decision that will shape the southern response to Cao Cao’s advance.

Setting and Military Role

When the question of policy arises, Zhou Yu is at Poyang Lake conducting naval exercises. Sun Quan’s mother recalls the counsel of Sun Ce, who had advised that Sun Quan rely on Zhang Zhao for domestic affairs and Zhou Yu for external affairs. Lu Su therefore goes to consult Zhou Yu, whose presence at the lake ties the political debate to military preparation.

The Debate over Resistance

Lu Su receives reassurance from Zhou Yu that he will support him once Kong Ming arrives. But the competing positions remain unsettled: a delegation led by Zhang Zhao argues for surrendering to Cao Cao, while military leaders urge resistance. Zhou Yu appears to align himself with each side in turn and postpones his decision until the next day. Poyang Lake thus enters the narrative as the setting from which Zhou Yu is drawn into a consequential debate, rather than as the site of a described engagement.

Narrative Significance

The lake’s brief appearance establishes Zhou Yu’s naval activity before his role in the deliberations becomes clear. It also marks the contrast between preparation for external conflict and uncertainty within Sun Quan’s court: Zhou Yu is exercising the forces that may be needed, even as the question of whether to use them remains unresolved. The supplied account gives no further description of the lake itself or of military action taking place there.
