The Seven-Step Poem: Cao Zhi's Life-and-Death Game and Literary Legend in "Romance of the Three Kingdoms"

Brief Introduction

"Boiling beans to burn the beanstalk, the beans in the pot shed tears. Originally born of the same root, why must you roast me so urgently?" This widely beloved Seven-Step Poem is one of the most famous allusions in the history of Chinese literature. The story recounts the legendary experience of the Wei Kingdom scholar Cao Zhi during the Three Kingdoms period, who successfully averted a crisis when facing a death threat from his elder brother Cao Pi by reciting this poem within seven steps. This story not only showcases Cao Zhi's extraordinary talent but also profoundly reveals the tragic color of fratricide under feudal imperial power.

Core Knowledge Points

* Poem Content: The most widely circulated version consists of four lines in five-character verse. It uses the relationship between beans and beanstalks to metaphorically represent brotherhood, questioning why those from the same root must torment each other.
Historical Authenticity: This incident is not recorded in the official history Records of the Three Kingdoms. The allusion first appeared in Liu Yiqing's notebook fiction from the Southern Dynasties, A New Account of the Tales of the World: Literature*. Therefore, it is viewed more as a literary creation rather than a strict historical fact, aiming to highlight Cao Zhi's quick wit.
* Symbolic Meaning: The poem has become a classic metaphor for internal strife and brothers turning against each other. It holds high cultural recognition and is often used to warn about the importance of internal unity.

Connection with "Romance of the Three Kingdoms" Content

In Luo Guanzhong's classical masterpiece "Romance of the Three Kingdoms", the story of the Seven-Step Poem is depicted in detail, becoming one of the climactic plots of the power struggle in the book.

* Chapter Location: The story appears in Chapter 79, "Brother Forces Brother, Cao Zhi Composes a Poem; Nephew Entraps Uncle, Liu Feng is Executed".
* Plot Background: After Cao Cao died of illness, Cao Pi succeeded him as the King of Wei. Cao Pi was naturally suspicious and feared his younger brother Cao Zhi's talent and reputation, worrying that he might threaten his throne, so he set up a trap.
* Life-and-Death Test: Cao Pi ordered Cao Zhi to compose a poem within seven steps. If he failed to recite it, he would be executed. This was a naked power purge, with a tense and oppressive atmosphere.
Story Outcome: Cao Zhi sorrowfully recited the Seven-Step Poem* (a six-line version in the novel, later evolved into four lines). After hearing it, Cao Pi was ashamed and moved by brotherly affection. He ultimately spared his life but demoted him to the Marquis of Anxiang, stripping him of real power.

Cultural Impact

Although historians doubt the authenticity of the story, the widespread dissemination of Romance of the Three Kingdoms has made "composing a poem in seven steps" a synonym for brilliance. This plot successfully shaped Cao Zhi's image as having "talent enough to fill eight dou" (extraordinarily talented), while also deepening Cao Pi's literary persona as "mean and ungrateful." It transcends historical research to become an eternal symbol in Chinese culture regarding wisdom, family affection, and power games, often used in education and literary references by later generations.
