公孫淵
Jiang Ji replied: "He knows that our defences are strong and that he won't gain any advantage. If he sends his forces deep into enemy territory, it won't be a sustainable campaign; if he attacks only the periphery, it will be a waste of manpower and resources for him. Sun Quan doesn't even care when his sons and brothers are in danger, so why would he care about a distant ally who has humiliated him before? The reason why he is spreading news that he will be sending aid to Gongsun Yuan is because he wants to confuse us. He will only take action if we fail to defeat Gongsun Yuan. However, as we are separated by land and water from Liaodong, if we attack Liaodong, we must ensure that we conquer it swiftly, or else Sun Quan might send lightly armed forces to launch small raids at our borders. This is something we should be wary of."
