Linghu Yu plotted with Wang Ling against Sima Yi to enthrone Cao Biao(曹彪) over Cao Fang to reduce the Sima family's influence over the Wei court.
In 226, as Cao Pi laid on his deathbed, he entrusted his successor Cao Rui to the care of Sima Yi, Cao Zhen, and Chen Qun.
Sima Yi's Liaodong campaign occurred in 238 during the Three Kingdoms period of Chinese history.

His father had appointed three regents for him—his distant cousin Cao Zhen, the steady administrator Chen Qun, and the shrewd strategist Sima Yi.
In 236 under the order of Emperor Ming of Cao Wei, Sima Yi conquered the Gongsun family and annexed Liaodong, Lelang and Daifang to Wei.
Sima Fang had eight sons (ranked in decreasing order of seniority) — Sima Lang, Sima Yi, Sima Fu, Sima Kui, Sima Xun, Sima Jin, Sima Tong and Sima Min — who were collectively known as the "Eight Das" because their courtesy names all contained the Chinese character da (達).
During Cao Pi's reign, he rose up the ranks and became a subordinate of the Wei marshal Sima Yi.
However, the situation was reversed after the Incident at Gaoping Tombs, during which Cao Shuang's political enemy, Sima Yi, wiped the whole clan of Cao Shuang out, close aides like Deng Yang and several friends of Zhuge Dan were put to death, and Xiahou Xuan was replaced by Guo Huai.
