what are the bow sings

To help you understand what "bow sings" may refer to, I will consider a few possibilities.

If you meant "bow strings," they are the strings on a bow used in archery. Bow strings are typically made of materials like synthetic fibers or natural materials such as animal gut. They are attached to the ends of the bow limbs and provide tension to propel the arrow when the bow is drawn.

If you meant "bow signs," it could refer to signs or gestures made with a bow (the act of bending at the waist) as a symbol of respect or gratitude in certain cultures. This is often seen in formal settings, ceremonies, or interactions with dignitaries.

If you meant something else, please provide more context or clarify your question so I can assist you further.
