Which poem did Cao Zhi use in Seven Steps Poetry to express his inner grief and indignation?

"This is the same root, why rush to fry?"

The whole poem of the seven-step poem is:

Boil beans and burn beans, and the beans cry in the pot.

We are born from the same root. What's the hurry?

Cook beans to make bean soup. I want to filter out the residue of beans and leave the bean juice for soup. The beanstalk burns under the pot, and the beans cry in the pot. Beans and beanstalks originally grew on the same root. How can beanstalk torture beans in such a hurry?

This poem uses the seeds and beans from the same root to compare the half-brothers, and uses the seeds and beans to compare the flesh and blood brother Cao Pi who killed his younger brother, expressing strong dissatisfaction with Cao Pi, vividly and simply reflecting the cruel struggle within the feudal ruling group and the poet's own difficult situation and depressed thoughts and feelings.

Extended data:

In the first month of the first year of Huang Chu (220), Cao Cao died at the age of 66, and Cao Pi was promoted to Wang Wei by the prince. In October of the same year, Emperor Xian of Han Dynasty was forced to abdicate, and Cao Pi acceded to the throne, claiming himself.

Cao Pi couldn't let go of the experience of fighting for the Crown Prince. After he proclaimed himself emperor, he still held a grudge against Cao Zhi. He was worried that this learned and politically ambitious younger brother would threaten his throne, so he tried to get rid of him. Cao Zhi knew that his brother had deliberately framed himself, but he could not excuse himself. He had to write a poem within seven steps in extreme grief and indignation.
