This object is carved from Hetian white jade and is in the shape of an open-worked jade bi with extension. The top part of the extension is decorated with a jade kwei, which is decorated with low-relief patterns of the Emperor of Heaven. The lower part is decorated with a mountain-shaped object followed by an open-work seal script (元) Yuan character, together with the open-work seal script (鼎) Ding and in the hole of the jade bi, indicating the reign title of Yuan Ding. Below the Yuan character is decorated with a divine face, and on both sides of the Yuan character are decorated with huang which has a dragon lying inside. A divine face is decorated below the character Yuan and a standing dragon next to the jade bi. The jade bi is divided into two sections. The outer section is decorated with two sets of open-work carvings of god’s faces at the four corners facing each other. The inner section is decorated with low relief of god’s faces facing each other. In terms of cultural significance, the bi is mainly composed of four auspicious elements of the Chinese jades, incorporating auspicious elements of gods, dragons, and phoenixes, praying for auspiciousness and prosperity in the Yuan Ding era. As far as the autistics are concerned, the object is exquisitely carved in great detail, and the presentation of each pattern is vivid. In addition, the object had signs of differential weathering, diffusive marking, and dissolved pits. It is a truly fine jade bi with the extension of the Han Dynasty.
