元代風格。白玉質。器呈扁圓體，一面高浮雕出廓，琢雙螭紋，呈攀爬狀，身形修長，蜿蜒盤曲於璧面，四肢攀爬有力，長尾翻卷，一面光素。《說文》：“螭，若龍而黃，北方謂之地螻，從蟲，離聲，或無角曰螭”。整體器形小巧，工藝古拙，螭身鏤空成孔，可穿系佩掛。 Made in the style of the Yuan period. The white jade is mellow and refined. The bi is of a flat round shape with one side carved with two chi-dragons in high relief out of the bi. The chi-dragons are crawling with their long bodies coiling on the surface of the bi. This emanates the typical style of the Yuan period.
