This poem is written purely in a metaphorical way. The language is simple and the meaning is clear. There is no need for further explanation. Only a few words and sentences need to be slightly clarified, and the meaning is self-evident. The "shu" in the second sentence refers to filtering the cooked and fermented beans to make a flavored juice. "萁" refers to the beanstalk, which is used as firewood after drying. The beans that are burned and cooked are the beans that grow from the same root as themselves. It is a metaphor for brothers who press too hard and kill each other. This is actually against the laws of nature and is normal. Not tolerated. The poet's clever use of metaphors, clever use of words, and blurting out the words in an instant are truly breathtaking. The phrase "We are born from the same roots, why rush to fight each other?" has become a common expression for people to advise people to avoid brothers fighting against each other and killing each other for thousands of years, which shows that this poem is widely circulated among the people.
Cao Zhi’s inner sorrow and indignation is expressed through the daily phenomenon of burning beans and boiling beans.
