Carved with yellow tone jade, the object is a bi disk. It is two sides symmetrical design with two sections presented.  The outer section is decorated with crop motif. The inner section is decorated with dragon and phoenix low relief carvings.  The bodies of these aesthetically designed creatures are decorated with detailed circling clouds to imply that they are flying in the sky.  Bi disk is the ritual jade dedicated to heaven in order that sufficient rainfalls are given to nurture the crops. Antiquity evidences are calcification, dissolved pits, diffusive markings and differential weathering.   (The Peace Garden Museum Collection. Script by Prof.Chen)
