Primitive man of the seven-step poem

The original is not a seven-character quatrain. Because that's not the era of seven-character quatrains.

Literature of Shi Shuo Xin Yu;

Boil beans for soup,

Fermented black beans are considered as juice.

The mash burns under the pot,

The beans are crying in the kettle.

Originally born from the same root,

What's the hurry?
