One day, Cao Pi called Cao Zhi to him and asked him to write a poem within seven steps to prove his talent in writing poetry. If he can't write it, it will be tantamount to deceiving the emperor and putting him to death.
Cao Zhi was sad and angry when he knew that his brother was going to kill him. He fought back his grief and tried to think about it ... Sure enough, he wrote a seven-step poem and read it out on the spot:
Soak in the kettle, and the beans cry in the kettle.
We were born from the same root, so why should we speculate with each other!
