Zhen Mi: Originally the wife of Yuan Shao's second son Yuan Xi, she later married Cao Pi and had a son, Cao Rui.
First briefly introduce Zhen Mi, and then tell a very interesting guess.
1. Why does Cao Pi dislike Cao Rui?
A: It is possible that Cao Rui is not Cao Pi's son, he is Yuan Xi's son, because Cao Rui was born prematurely.
2. Hypothesis 1 holds, why didn't Cao Pi abolish Cao Rui?
Answer: First of all, Cao Cao liked this eldest grandson, and the second was that Cao Pi did not expect that he had only been emperor for six years, and his life was too short, and his younger sons were too young.
3. Assuming that 1.2 is true, what is the emotional dispute between Cao Pi, Cao Zhi, and Zhen Mi?
Answer: Cao Pi used Cao Rui's life as a threat to let Zhen Mi seduce Cao Zhi and ruin his reputation, when Cao Cao's family all went out, leaving only Cao Zhi and Zhen Mi at home, which always felt that someone had deliberately arranged.
4. Assuming that 1.2.3 all hold true, is there any benefit to doing so?
A: Three benefits. The first Zhen Mi saved his son's life; the second Cao Zhi loved the beauty and did not love Jiangshan, he got the beauty; the third Cao Zhi's reputation was bad, and Cao Pi naturally became the son of the world and got the Jiangshan. Kill three birds with one stone.
The above is pure speculation, does not represent the real history, do not believe in rumors, do not spread rumors...
