Bird wings are classified into yang and yin sides. The yang side refers to the outside of a bird's wings, while the yin sides, the inside. As of the feathers of yang wings, they extend from the body outward with the first layer covering the second, the second covering the third, and so on. The yin wings are on the opposite sides of the yang wings and are overlapping in a different direction. While carving the movement of flying of a bird, a craftsman must pay attention to the yang and yin sides.
