Background: Cao Pi is Cao Zhi's brother, and both of them are the sons of Cao Cao, Emperor Wu of Wei. Cao Zhi has few talents, and Cao Cao once wanted to abolish Cao Pi and make Cao Azhi a prince. In order to consolidate his political position, Cao Pi tried his best to succeed him. After Cao Pi became Wei Wendi, he was forced to write poems in order to further attack Cao Zhi's influence (the purpose was to kill Cao Zhi if he failed). Seven-step poetry was born under such a background.
Cao Zhi's inner feelings: Personally, I think Cao Zhi has never been interested in the struggle for the throne, which is fully proved by Cao Cao's taking him to send troops (the use of troops in ancient times is the embodiment of imperial power, which means that Cao Cao hopes that Cao Zhi will inherit the throne), but Cao Zhi is too drunk to sleep at this point. Everything xelloss took away was only his unilateral reason, so it must be very depressing for Cao Zhi to be suppressed for no reason. Brothers and sisters, brilliant and suppressed, can't serve the country. This can be felt in Cao Zhi's later poems.
I want to say: Cao, the landlord, this question is too embarrassing. You haven't thought about it yourself. You will be miserable in high school Chinese in the future!
