Is “Forced Cao Zhi to compose a poem in seven steps” true?
based on fact
The 'A New Account of the Tales of the World' records the seven-step poem; however, the 'Records of the Three Kingdoms' does not mention it, and scholars generally consider it a later fabrication attached to Cao Pi's oppression.
Cao Pi
In official history, he is Emperor Wen of Wei, a literary figure and statesman; in fiction, he is portrayed as a narrow-minded villain who oppresses his own brother.
