Looking at the kings of ancient China' dynasties, countless people were killed, exiled, and poisoned, and the one with the best ending was Cao Yi, the last emperor of Cao Wei during the Three Kingdoms period. Cao Huan was Cao Cao's great-grandson, Cao Rui's adopted son, who was not originally eligible to inherit the throne of the State of Wei, and after the assassination of Cao Huan, the Duke of GuiguiXiang, Sima Zhaoli became the heir of the Wei Ming Emperor Cao Rui, and in this way, Cao Huan involuntarily became the fifth emperor and the last emperor of the State of Wei.

When Cao Yan succeeded to the throne, the power of the Wei state had already been held by the Sima family, and Cao Huan became another puppet emperor after Cao Fang and Cao Huan, and because he witnessed the tragic end of the rebellion of the noble township princes, Cao Yi did not have any thoughts and moves to revive the imperial power after he succeeded to the throne, he just was at ease to be a puppet emperor at the mercy of Sima Zhao.

However, such a puppet emperor career, Cao Wan only passed six years. In the second year of Xianxi, that is, in 265 AD, after the death of Sima Zhao, the King of Jin, his son Sima Yan succeeded to the throne, and the new King, who was not yet 20 years old, immediately forced Cao Huan to take the throne, and the scene of the Cao clan forcing the Han clan to abdicate and relinquish the throne was staged again in less than 50 years. Cao Wan's abdication marked the end of the 46-year-old Kingdom of Great Wei and the beginning of the Jin Dynasty's war to unify China.

After the abdication, Cao Yan was enfeoffed by Sima Yan as the King of Chen Liu, eating ten thousand households, and his palace was arranged in Yicheng, while giving generous economic treatment, Sima Yan also gave Cao Yan dignity politically, and The Jin Emperor allowed King Chen Liu to use the Tianzi Banner, prepare a five-hour deputy car, carry out the Wei state Zhengshuo, and the system of ritual music in the suburbs was imitated by the system of the early Wei state, at the same time, Cao Yan did not have to be a subject when he wrote a letter, and did not have to bow down when accepting the emperor's edict.

After Cao Yi abdicated the throne, he served as king of Chen Liu for another thirty-six years, and finally died of illness at the age of 58, while the Jin Dynasty crowned Cao Yan's title of Chen Liu king was passed on for 214 years, and finally ended in the Southern Dynasty Qi. As an emperor, Cao Huan was obviously unlucky, but as the last emperor of a dynasty, Cao Huan seemed to be lucky again. Its political status, treatment and outcome can be said to be the best among the kings of all generations.
