Ning Sui

His is the plan that saves Jiang Wei's army. With the bridge held and Deng Ai behind, 'Advance and retreat seemed equally impossible' and Jiang Wei cries 'Heaven is destroying me!' — and Ning Sui answers: 'If our enemies are blocking Yinping Bridge, they can only have left a weak force in Yongzhou. We can make believe to be going thither through the Konghan Valley and so force them to abandon the bridge in order to protect the city. When the bridge is clear, you can make a dash for Saber Pass.' It works exactly as described.
