Casting such a large bronze ware, it is very complicated to cast the parts separately first and then combine them into a whole. When casting, it takes two or three hundred craftsmen to cast at the same time and cooperate closely to complete it. Smecta is determined to contain copper, tin and lead. The proportion of these three metals is reasonable, which reflects the wisdom of merchants and craftsmen.
The output and quality of bronzes reflect the rise and fall of national strength. The exquisite and magnificent bronze cauldron symbolizes the splendid civilization of that era.
Wu Ding, the stepmother, is not only elegant, magnificent and ornate, but also has excellent casting technology. The method of ceramic mold casting is adopted. The mold is made of a mold and a bottom mold, and the outer mold is made on it after drying in the shade. The mold consists of a belly mold, a top mold, a core, a base and a gate mold. The casting of Wu Ding, the stepmother, fully embodies that the bronze casting in the late Shang Dynasty is not only large in scale, but also well organized and meticulous in division of labor. This shows that the bronze casting industry in Shang Dynasty has a large production scale and outstanding technical achievements. The existence of stepmother Wu Ding is enough to represent the highly developed bronze culture in Shang Dynasty, so people agree that stepmother Wu Ding is a masterpiece of bronze culture in Shang Dynasty.
Ding's cultural implication is profound and solemn, with high aesthetic value. It was praised by Li Zehou, an aesthete, as "the bronze art with the most aesthetic value in the mature period of China bronze art", and her stepmother Wu Ding is the most famous four-sided tripod among bronze ding, representing the splendid bronze culture of Shang and Zhou Dynasties, so her stepmother Wu Ding enjoys the reputation of "the king of bronze".

The upper end of the foot is decorated with embossed gluttonous patterns, and the lower lining is lined with concave strings.
The inner wall of the abdomen is cast with the word "stepmother E". The font is rich and plump, the strokes are peaked at the beginning and end, and the fat pen is used occasionally.
