陳泰
The Wei regent Sima Shi summoned Yu Song (虞松) to seek his opinion on how to deal with the Wu and Shu incursions in the east and west respectively. Yu Song analysed the situation and said that the defences at Hefei were strong enough to resist the Wu attack for some time and that the Wu forces would eventually withdraw once they lost momentum. He suggested that they launch a swift counterattack on the Shu invaders to catch them off guard and drive them back. Sima Shi agreed and ordered Guo Huai and Chen Tai to lead the Wei forces stationed in the Guanzhong region to attack Jiang Wei and lift the siege on Didao. Chen Tai attacked the enemy at Luomen (洛門; in present-day Wushan County, Gansu). Jiang Wei eventually pulled out his troops when they ran out of food supplies.
