What do you mean by ten threads?

This texture usually refers to the spiral pattern of fingers, and ten snails represent ten dustpans.

There are ten snails on the pattern, and the spiral on the fingerprint refers to the pattern on the finger that looks like snails turning in circles. Ten snails represent ten dustpans, which, contrary to buckets (ten snails), are all traces left by matriarchal clan society. From the perspective of numerology, the more snails on the fingerprint, the better, because the snails on the fingerprint represent ten dustpans, and ten dustpans represent good life and good luck.

People with ten lines in their palms are introverted and not good at expressing themselves.
