Chen Shou, the author of The Three Kingdoms, commented on two examples of Guo Huai's "careful planning" in marching operations.

Answer: Example 1: In the confrontation with Liu Bei, he advocated retreating to the shore and deploying in the distance to induce the enemy to cross the river before attacking ("It is better to be far away than to be near the water, and then strike." )

Case 2: When confronting Zhuge Liang, he advocated taking the North Plain first. ("Huai Ce Liang seeks the North Plain, so you should follow it first")

Case 3: When confronted with Zhuge Liang, he thought that his western expedition was false and his attack on Yang was real ("Huai Du saw the western expedition for this reason, and if he wanted to make the officers and men react again, he would attack Yang Sui 'er")
