Bronze square tripod, Early Shang Dynasty (about 1600 BC - 1400 BC)0 The overall height is 86.5 cm, and the mouth length is 61 cm. Unearthed in Zhangzhai South Street, Zhengzhou, Henan in 1974. Henan Museum Collection.

The mouth of the tripod is rectangular, with a pair of arched ears on the top, a deep abdomen, a slightly introverted abdominal wall, a flat bottom, and four hollow cylindrical feet with upper thickness and lower thickness. A set of single-line animal face patterns is cast on each of the four sides and four corners of the body, and the two sides and lower parts of each side are decorated with milk dice patterns, and the upper parts of the feet are decorated with animal face patterns. At the time of excavation, there were smoke marks on the bottom and feet of the vessel.

Ding is used for cooking during sacrifices, recommending sacrifices, cooking during feasts, and serving meat. This square tripod is located in a pit about 300 meters outside the north section of the west city wall of Zhengzhou Mall. It is thick in shape and mysterious and solemn in decoration. Fang Ding adopts a separate casting method, first casting the ears of the tripod, casting the ears together when casting the belly, and finally casting the legs and belly of the tripod. In order to make it firm, the perimeter where the foot and the bottom of the abdomen are combined is also thickened, so that the foot and the bottom are tightly combined. There are two square tripods of the same shape unearthed from the pit, of which the padding part of the larger one was dug down to keep the mouths of the two square triplets flush. This deliberate practice made the cellar pit in Zhangzhai South Street have a strong ritual element, and scholars speculated that it was related to sacrificial activities such as "suburban" and "fu" at that time.
