The Jin was a table for holding wine vessels in ancient China. Being rectangular in shape with a panel in the center, the borders and the four sides were made up of openwork layered cloud designs. Twelve dragon-shaped beasts with tongues sticking out and bodies bent, serve as the supports of the table. The four sides were attached with twelve dragon-shaped beasts sticking out their tongues, and their bent bodies, coiled tails, and climbing postures, serve as embellishment.

 Its ingenious and monumental design, magnificent and elegant shape, and exquisite openwork ornaments, led to its label as a flawless artistic treasure. The Jin was cast with lost-wax technique, which was capable of cast the more intricate products by breaking away from conventional disadvantages of the clay mold craftsmanship, hence demonstrating the beauties of openwork and sculpture. This marked a great point of progress in the bronze casting technique of China. The present Jin is the earliest example cast with the lost-wax technique known to date in China. Its discovery determined the time of lost-wax technique of China over a hundred year earlier than previously believed.
