He lied to xelloss that he could live to be eighty, and as a result, xelloss died at forty. Why did he lie to xelloss?

It was Zhu Jianping who told Cao Pi's fortune, not Guan Ju. This man was a famous fortune teller at that time. At that time, Xelloss met him at a banquet, so Xelloss asked Zhu Jianping to calculate his life span. Zhu Jianping told xelloss that he could live to be eighty, but it was difficult to live to be forty. Xelloss should be more careful, but xelloss didn't cross forty years old, so Zhu Jianping didn't cheat xelloss.

Cao Pi is the eldest son of Cao Cao and the founding emperor of Cao Wei. Cao Cao has more than 20 sons, among whom except Cao Pi, Cao Zhi, Cao Chong who became a poet in Qibu, and Cao Cao's eldest son Cao Ang are all satisfactory. But except Cao Zhi, the last two died in front of Cao Cao, and even Cao Chong died at the age of thirteen. Therefore, although Cao Cao has many sons, he has little choice.

Cao Pi and Cao Zhi were both born by the same mother, and their father and son were called "Jian 'an Three Caos" in the history of literature. The main reason why Cao Pi was chosen as Cao Cao's successor was not that Cao Pi was too good, but that Cao Zhi was too careless. Cao Zhi, as one of Chu Jun's references, also experienced Sima Men's trespassing after being drunk, so Cao Cao was dissatisfied with Cao Zhi and attached himself to Cao Zhi as his successor.

After becoming an emperor, Cao Pi was a good emperor who made great efforts to govern. He unified the northern region with the Nine Grades Zhengzhi system, but the only bad thing about Cao Pi was that he died too early. He died after seven years as emperor, only forty years old when he died, in the prime of life, and his heirs were not trained. Then Sima Yi, who was not his confidant during the emperor's period, seized the fruits of national construction, which Cao Pi himself might not have thought of.
