The bi-disk has a dual motif for both sides. On each side there are two layers of motifs separated by a rope motif. The inner layer is crop motif. The outer layer consists of four sets of spirit’s face. The spirit’s face is composed from two dragon heads which in turn composed from phoenix. The carving technique of the artifact applies the typical Western Zhou Dynasty 45 degree slant carving and slim incised lines for the Spring Autumn period to the greatest extent. The spirit should be touched by offering this bi-disk. Judging by the mastery carving and superior and unique design, this is believed to be the bi disk closest to the legendary Ho’s bi before fully identified. Antiquity evidences consist of differential weathering, diffusive marking and ancient tool mark. This is a candidate of the legendary Ho’s bi.
