The wolf's mane is distinct, the muscle texture is clear, the teeth are sharp, and the eyes are sharp, vividly restoring the wildness and majesty of the wolf. The side is also equipped with auxiliary decorations such as winding patterns, which increase the delicacy and layering of the ring. Wolves are the strongest among all beasts, symbolizing fearless courage and powerful execution.
