Historical Information
Sima You (248-283, style name: Dayou) wawas the second son of Sima Zhao, a regent of the Cao Wei state during the Three Kingdoms period. Sima You became the heir to his uncle, Sima Shi, who had no sons of his own. You proved adept at studying and writing, impressing even his grandfather Sima Yi. When Wang Ling rebelled, Sima You accompanied his grandfather as an aid. Four years later, his uncle/adpoted father died shortly after repressing Guanqiu Jian and Wen Qin's rebellion.

In 265, Sima You was appointed King of Qi, increasinghis rank. Sima You served in both domestic and military roles though his adult life, rising in power and respect. However with the appointment of Sima Yan as the new Emperor, bad blood was introduced between the siblings. Recognizing this danger, both Sima Zhao and Wang Yuanji both entreated Sima You and Sima Yan to work together to avoid conflcit on their deathbeds. Both complied until the death of Sima You.

When Emperor Wu (Sima Yan) appointed Sima Zhong as heir apparent, Yan feared You could overpower his probably handicapped son. Thus he ordered You to return to Qi, far from Luoyang in 282. This move demoralized Sima You, who soon fell ill from the stress and died soon after at the age of 36.

Sima You's son, Sima Jiong, was one of the eight princes involved in the War of the Eight Princes during the reign of Emperor Hui, the second emperor of the Jin dynasty.
