Second, many Liangzhu Culture jade artifacts with smooth cut marks on the surface of the jades of which the reasons behind that are still unknown. Third, many Liangzhu Culture jades are carved with the shape not in proportion to the boundary of raw material. This is the practice called carving under the limitation of the size of the 
material. This is the practice that let the carving object bigger with an imperfect proportion of artwork rather than carving smaller object with perfect proportion of artwork. Sample jades are as follows:
