First, Cao Pi was frightened from childhood and eventually contracted pneumonia. As early as when Cao Pi was 5 years old, Cao Cao taught him to shoot arrows, learned to ride horses when he was 8 years old, and went to war with Cao Cao when he was 10 years old. Therefore, Cao Pi's physical quality is definitely leverage. But at first, he was not Cao Cao's favorite son. Living in the majesty of my father all the year round, fighting with my family brothers will naturally lead to psychological problems over time. When he finally became an heir and usurped Han's independence, the huge workload that followed would also overwhelm him. At home, we should guard against the counterattack of our brothers and the Han family, and look after Sun Wu abroad, adding to Cao Pi's physical burden.
Moreover, as an emperor who can mobilize all the resources in the country, Cao Pi's private life is also somewhat chaotic, and he often goes to the harem party every night. If you don't control this behavior, even if it is perfect every day, it won't help. In addition, Cao Pi personally led the troops to attack Wu. Because the war lasted until winter, Cao Pi contracted lung disease because of acclimatization and days of fighting, which made him die of lung disease soon after he returned to Xudu. Even today, lung disease is a thorny disease, let alone during the Three Kingdoms period. In addition, Cao Pi's work pressure was too great and his private life was chaotic, which led to his poor physical fitness and his early death.
Secondly, Cao was born Rui. He has a distorted personality and an absurd life. After redress was executed by xelloss, Cao Rui was also punished and abolished. At this time, Cao Rui was only 7 years old. Losing his mother at a young age is extremely cruel to a child and distorts Cao Rui's character. It can be seen from Cao Ruina Toy Boy's later actions that his psychological problems are extremely serious. And later, when he became emperor, he gave the Queen Mother Guo a death present, which can prove that Cao Rui has been deeply concerned about the death of his biological mother and xelloss.
This resentment, as well as the yearning for his mother, made Cao Rui's character extremely distorted. In addition, he holds the supreme power of the Cao Wei regime, which finally allows him to do whatever he wants. When his temper comes, he is full of debauchery and extravagance. Over time, he was born physically unbearable and went on strike. Unfortunately, Cao Cao fought all his life, but because his son and grandson died young, he finally made a wedding dress for Sima's family.
