Dated back four to five thousand years, Liangzhu Culture mainly covered the area of Lake Tai in southern China. The varieties of jade artifacts of Lanzhou Culture are rich.
The jade artifacts of Liangzhu Culture have three significant elements worth considerations. The first element is the impact on the motifs of jade artifacts of the later periods. For example, the god’s face motif constitutes the major motifs of the Spring and Autumn Period. The curling claws shown under the God’s face constituting the claws of the dragon for the Shang and Western Zhou dynasties. 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.
