Everyone's fingerprints are different. The one with a closed circle in the middle is called a dustpan. If the mouth sticks out, it is called a dustpan.

Jianye district's Count Your Fingers: "One finger is clever, two fingers are good, three fingers pick straw, five fingers are poor, six fingers are rich, seven fingers are pawnbrokers, and nine fingers are scholars.

"Counting Songs" circulated in Qinhuai District: "One clever, two clumsy, three or four tongue-butting, five or six riding a flower horse, seven or eight first, nine or nine short of ten.
