《周礼·春官宗伯·郁人&典瑞》
有刻纹隆起的圭、璋、璧、琮，它们的衬垫都用丽种颜色绘饰一匝，用以看望或慰问王。
瑑、圭、璋、璧、琮，缫皆二采一就，以覜聘。
For the scepters, tablets, and round tablets that are designed with raised lines, the padding is painted with fine, bright colors around its circumference, and is used in visiting or offering condolences to the Son of Heaven.
