李丰
Sima Yi died in 251 and his eldest son Sima Shi inherited his position in the Wei imperial court. In 254, Li Feng, Xiahou Xuan and Zhang Ji (張緝) planned to overthrow Sima Shi, but their plan was leaked out and they were all executed. The emperor Cao Fang was unhappy with Sima Shi's authoritarian attitude and incurred the latter's displeasure. Months later, Sima Shi deposed Cao Fang and replaced him with Cao Mao. Guanqiu Jian, who was stationed in Shouchun, and Wen Qin, the Inspector of Yang Province, heard news about the deaths of Li Feng, Xiahou Xuan and Zhang Ji, and became afraid of being implicated. Guanqiu Jian's son Guanqiu Xun kept urging his father to stage an uprising to defend their state's sovereignty from Sima Shi.
