Among the types of bronze tripods, the big gram copper tripod is very popular. The inscription on Da Keding is an important document for the study of the history of the Western Zhou Dynasty. They are of great significance to the study of the Western Zhou Dynasty's **, etiquette, and land system. Its content is divided into two parts. First of all, the ship's owner, Ke, praised the merits of his grandfather, Shi Hua's father, and recounted that the king of Zhou appointed Ke as a chef to carry on the important task of conveying the king's order.
During the Western Zhou Dynasty, the appointment of ** adopted the hereditary system of the secretary and the servant. Therefore, long texts praising the merits of ancestors can often be seen in the golden texts. This custom is not only a ceremonial requirement, but also carries a declaration of succession and expresses the political role of emulating ancestors and continuing to honor the royal family. Although the official positions of nobility were hereditary, they had to be solemnly reassigned by the emperor to show the majesty of royal power, and the positions conferred could also be different from those of their ancestors.
According to the "Zhou Dynasty", the duty of the Zaifu was precisely "to control the laws of the dynasty, and to control and prohibit from the positions of the king, the three princes, the six secretaries, the officials, and the officials". Govern the ministers and treat the order of the guests. "All the ministers are restored, and all the people are opposed", which is consistent with the emperor's requirements for Ke to pass on the king's orders and enter the next affairs. Therefore, the master of Da Keding should take the position of Zaifu. After the excavation of Da Keding, many scholars have studied and explained it, among which the famous ones are Sun Yirang's "Keding Interpretation" and Wang Guowei's "Keding Ming Interpretation" and so on.
