Carbonized grains such as rice, barley, millet, and Job's tears were excavated from habitation sites, indicating that mixed grain farming had become widespread across the Korean Peninsula. It is also inferred that rice farming had become quite common in both the northwestern regions and the southern areas. Rice farming in the Han River basin is closely related to the southward movement of residents from the Pangyi () Pottery culture in the northwestern regions. As these southern-moving Pangyi Pottery people interacted and blended with the local Minmuni-toki-in () communities, rice farming became widespread in the Han River basin and further extended to the southern regions.
