Guo Huai
In 234, Guo Huai joined Sima Yi in leading Wei forces to resist another Shu invasion led by Zhuge Liang. When Sima Yi and his troops were stationed at the south of the Wei River, Guo Huai urged them to move to the plains on the north bank of the river as he foresaw that Zhuge Liang would attempt to seize the plains. When the other officers disagreed, Guo Huai said, "If Zhuge Liang crosses the Wei River and occupies those plains, his troops will have access to the mountains in the north. If they block the road through the mountains, it will cause fear and panic among the people living in the region. This isn't helpful to our State." Sima Yi agreed with Guo Huai and sent him to occupy the plains. While Guo Huai and his men were building a camp on the plains, they came under attack by Shu forces but managed to drive them back.
