Did Xelloss really poison his younger brother Cao Zhang? What's the secret of Cao Zhi's ci?

In fact, there are different opinions about xelloss poisoning Cao Zhang, because there is no conclusive evidence to prove that xelloss poisoned Cao Zhang, and everything is just speculation. Although Cao Zhi's words imply that Cao Pi poisoned Cao Zhang, the implication is only our understanding. Personally, I don't think xelloss will poison Cao Zhang. First of all, Cao is not in the throne, he belongs to the battlefield, and he knows that he was born for the battlefield. Therefore, among the three countries, Cao is good at fighting and holds the military power. In fact, it can be seen from one thing that Cao is not on the throne. That is, after the death of Cao Cao, when Cao Zhang returned, he didn't take his troops back, not even a Qin Bing to Beijing.

This has shown that Cao Zhang does not want to compete for the throne. Let's take another look. Xelloss pays attention to Cao Zhang, because he holds the relieving power, and because he is united with Cao Zhi. Cao Zhang's mastery of the relieving is a good thing for Cao Wei, because Cao Zhang is really a good general. For example, he once made Xianbei surrender one soldier at a time. Therefore, Cao Zhang is very useful. Xelloss will not kill Cao Zhang easily. Even if he suspects that Cao Zhang and Cao Zhi are working together, then personally, it is Cao Zhi who is going to be killed. Because I have made it clear above that Cao Zhang is just a general. If Cao Zhi unites him, it is also Cao Zhi who wants to seize the position, and so is the mastermind Cao Zhi. Wouldn't it be better to kill Cao Zhi?

You kill Cao Zhang, there will be another Cao Zhang. The main problem is Cao Zhi. So I think it is impossible for Cao Pi to kill Cao Zhang. Many people say that Cao Pi poisoned Cao Zhang, and the evidence is Cao Zhi's words, which means that Cao Pi poisoned Cao Zhang. Cao Zhi made a word, two of which suggested that Cao Pi had poisoned Cao Zhang. The alliance drinks tears and a hundred people consult? . It means that when a monarch died, everyone shed tears at most, while Cao Zhang died, and all his colleagues were in tears. Because after Wang Wei at that time, Cao Pi's party department had some personality changes and was not very polite to ministers and princes. So governors are afraid that they will end up like Cao Zhang.

But I still have to say that this is just a guess.
