Cao Fang.

About Cao Fang

Cao Fang (232–274), courtesy name Lanqing, was the third and longest-reigning emperor of the state of Cao Wei during the Three Kingdoms period. He was an adopted son of Cao Rui, the second ruler of Wei. Cao Fang ruled from January 239 to October 254 as a nominal emperor before he was deposed by the regent Sima Shi, after which he became known as the "Prince of Qi". After the fall of Wei in February 266, Cao Fang was conferred the title of "Duke of Shaoling" by Emperor Wu of the Jin dynasty. When he died in 274, he was granted the posthumous name "Li", so his full posthumous title became "Duke Li of Shaoling".
