魏延
Wei Yan probably participated in most, if not all, of the five Shu invasions of Wei between 228 and 234. In 230, Wei Yan attacked and defeated the Wei generals Fei Yao and Guo Huai at Yangxi (陽谿; southwest of present-day Wushan County, Gansu). During the fourth campaign in 231, he also joined the Shu generals Gao Xiang and Wu Ban in resisting the main Wei army led by Sima Yi and scored a major victory over the enemy: they killed 3,000 Wei soldiers and seized 5,000 sets of armour and 3,100 crossbows. Sima Yi retreated back to his camp. As a reward for his contributions, the Shu government promoted Wei Yan to Vanguard Military Adviser () and Senior General Who Attacks the West (), and elevated him from a village marquis to a county marquis under the title "Marquis of Nanzheng" ().
