CaoZhen (185 – 231) was a military general under the powerful warlord CaoCao and succeeding rulers of the Kingdom of Wei during the late Eastern Han Dynasty and Three Kingdoms Period in ancient China.
According to the Chronicles of the Three Kingdoms, CaoZhen was a distant nephew of CaoCao.
In 195, as CaoCao was fleeing from rebels, he hid in the Qin's.
Ts'ao-Jui (205-239) was the son of Cao Pi and the second emperor of the Cao Wei.
When Cao Rui was born (likely in 205), his grandfather CaoCao was the paramount warlord of Han Dynasty, who had rendered Emperor Xian of Han a mere figurehead.
After Cao Pi, after his father's death in 220, forced Emperor Xian to yield the throne to him and established Cao Wei, Lady Zhen was not allowed to accompany him to the new capital Luoyang, and in 221 he forced her to commit suicide.
