"Shi Shuo Xin Yu" in the Southern Song Dynasty "Wen Di tried to make Dong Wang E write poetry in seven steps, but failed to achieve Dafa; The answer is a poem: "Boil beans to make soup, soak them into juice; Glutinous rice is burned in the kettle, and beans weep in the kettle; This is the same root, why do you want to speculate with each other! "

After Cao Pi ascended the throne, he ordered his younger brother Cao Zhi to write a seven-step poem.

Cao Zhi really wrote a seven-step poem.

Cao Pi was also moved by this poem and let Cao Zhi go.

Cao Zhi finished singing and just took seven steps.

Hearing this, Cao Pi was ashamed, spared the death penalty and was demoted to Anxiang Hou. The story of Cao Zhi's seven-step poem soon spread, and people praised him for his "seven-step talent".

"Eight fights" is a metaphor used by Xie Lingyun, a poet of the Southern Dynasties, in praising Cao Zhi, a poet of the Wei Dynasty in the Three Kingdoms.

He said, "There is only one stone in the world, and Cao Zijian (Cao Zhi) monopolizes eight fights. I have to fight, and the world is divided into one battle. " Later, people used the word "talented people" to describe people's outstanding talents.
