Biography
Cao Rui (204 or 205 – 22 January 239), courtesy name Yuanzhong, was the second emperor of Cao Wei during the Three Kingdoms period in Chinese history. There's historical debate about who his parents were. His mother, Lady Zhen, was initially married to Yuan Xi, a son of the warlord Yuan Shao. After Cao Cao conquered the north, she married Cao Pi, who founded the Wei state. Because of different records about Cao Rui's age at death, scholar Pei Songzhi concluded that his recorded age of 36 was wrong if Cao Pi was indeed his father. Later scholars Lu Bi and Mao Guangsheng suggested that Cao Rui might have actually been the biological son of Yuan Xi and not Cao Pi, a question that still hasn't been settled.
Before Fame
Cao Rui grew up in Cao Pi's household when the Cao family was solidifying their hold on northern China. His mother, Lady Zhen, known for her beauty and writing skills, was executed by Cao Pi around 221, supposedly after losing imperial favor. This situation made Cao Rui's early years in the Wei court politically unstable. Despite this, he was seen as a smart and capable young man and became crown prince before his father died.
