Techniques could be applied to each piece of jade to decorate in a unique style. One such technique in decorating is to make grooves in the jade. These were made in such a manner that some of the grooves could not be seen unless light was applied. With the use of light one could see many different special effects built into the jade objects. Such effects include the since of depth, three-dimensionally and especially mystery.
Light is needed in a spiritual sense in order to see the effects and dissolve mystery.
As mentioned above, these jades appear exclusively in the burials. Burials themselves should be considered to investigate if the placement of jades in the burials possess spiritual symbolism. These objects are often found in pairs in the burials. The quantity and the quality differs between burials. The difference in both quantity and quality seems to imply a hierarchy.
