Answer:
After the seven steps poem, Cao Zhi's situation did not get fundamentally better, and the Wei state still pursued the policy of strict restrictions on the imperial family, and Cao Zhi died in unhappiness at the age of 40.
1. Cao PI once ordered Cao Zhi, king of East Ah, to compose a poem within seven steps, and if he could not produce it, he would use the death penalty. Cao Zhi responded by writing a poem: "Cooking beans and holding them as soup, colling beans as juice." The pan burns under the kettle, and the bean cries in the kettle, which is born from the same root, and is fried in no hurry!" Cao PI was deeply ashamed when he heard this, and in front of his mother, he spared Cao Zhi the death penalty, but he still denounced him as an official of Anxiang.
2. Since Cao PI came to power, Cao Zhi had been subjected to political oppression and persecution. After experiencing great ups and downs, Cao Zhi became more unhappy, and his later life was even more different from his earlier life.
3. In 226, after the death of Cao PI, Cao PI's son Cao Rui took the throne. Cao Zhi was full of hope to lead the army and serve the country, but Cao Rui was still suspicious and scruple, and the attack and oppression on Cao Zhi increased, and Cao Zhi soon died of depression.
