The object is a rectangular shape, on which physical objects can be placed and charcoal fire can be placed below to achieve insulation, similar to modern hotpot. The objects are adorned with lifelike dragon and bird patterns, and at the lower copper door, there is a carved human figure, reflecting the strict criminal law system of the Western Zhou Dynasty. The unique shape and clever design make this copper cauldron a rare artwork, and also allow us to see the long history of hot pot.
