The Caofan millet paste soup has won the praise of "A Bowl of Millet Paste Soup: Filling the Homeland with Fragrance and Warming the Heart" and has become a golden name card for rural revitalization.

This indicates that the Caofan millet paste soup has, to a certain extent, been integrated into the local characteristic cultural system of Jinan.
