Jupiter is clearly talking about steamed pork why mention prose and pentameter again?

Is the questioner trying to ask "Why does Jupiter mention prose and quatrains when he is clearly talking about steamed pork?"? It is used to describe meat with little flour. In the article "Bamboo Show", Mu Xin first mentions steamed pork with less meat and more flour, and then he mentions prose, which turns into a five-word stanza, using fewer words to describe less meat and more flour, which shows the author's craving for food and his derision of the family in his miserable mountain life.
