Stacked carving is a unique technique of using wood, stone, bone, and other materials to create multiple layers of translucent carving. Craftsmen must have a clear mind and first divide the materials into thin slices, carving patterns of different depths layer by layer - the bottom layer is often densely laid out, while the upper layer gradually becomes ethereal. Petals with fine stamens, cloud patterns and water waves, stacked layer by layer, up to more than ten layers at most. When the light passes through, the layers suddenly appear, and the static pattern comes to life: butterfly wings tremble lightly, petals are exposed, creating a deep world in every inch. This technique originated in the Tang and Song dynasties, flourished in the Ming and Qing dynasties, and is now as rare as a star phoenix. Every surviving work is a poem composed of time and patience.
