A decorative carving form formed by completely hollowing out a pattern or background. Opencut carving can be divided into two forms. The form where the pattern pattern is hollowed out on the background and becomes transparent is called Yin Opencut carving; The process of hollowing out all the background parts except for the pattern patterns and retaining only the pattern patterns on the background is called yang transparent carving. Open cut carving is often used for panel like components in furniture.

A carving method in which the pattern is above or below the background and is on the same plane. When the pattern is below the background, it is engraved in yin, and when the pattern is above the background, it is engraved in yang. But regardless of whether it is engraved in yin or yang, all the patterns are at the same height as the surface of the carved component

A three-dimensional carving form in which the pattern is completely separated from the background and can be independently formed in any direction, similar to sculpture. The theme range of circular sculpture is very wide, from characters, animals, plants, and so on. The works carved with circular carvings are highly three-dimensional, vivid, realistic, and lifelike.
