Xiahou Xuan
Around 254, Li Feng, who held the position of Prefect of the Palace Writers () in the Wei government, secretly plotted to overthrow and assassinate Sima Shi. He also wanted Xiahou Xuan to replace Sima Shi as General-in-Chief (), and restore power into the hands of the Wei emperor Cao Fang, who was merely a puppet ruler under Sima Shi's control. To achieve his purposes, Li Feng secretly contacted Zhang Ji (), the emperor's father-in-law, and told him about his plan.
