These sacrifices use Ding Mingwen's family emblem to represent family glory.
First of all, it must be clear that bronzes cannot be cast privately. According to the system of rites and music, it can only be given to public officials by Zhou, which shows Zhou's authority, otherwise the ceremony will collapse.
For example, Fang Shangjian, which we are familiar with later, on the one hand represents the glory of the king's rights, on the other hand, it is the great glory of the receiver and is recognized. Bronzes are engraved with the owner's name or family emblem to show off their glory and achievements, so that future generations will always remember this glory.
Bronze ware is a treasure given by the Zhou emperor, and it is also a carrier for recording the manuscripts of gifts, which will be engraved with inscriptions. The original format of bronze casting inscriptions is emblem, which is used to identify the owner. Signs can be divided into complex and simple forms. The simple form only depicts the manufacturer's family emblem, or records the manufacturer's surname, official name and private name, such as "house number", which is more common in Shang Dynasty and less and less found in early Zhou Dynasty. Fan Shi appeared in the late Shang Dynasty and was mainly popular in the Western Zhou Dynasty and the early Spring and Autumn Period.
Inscriptions will mention the surnames of vassal States and clans, which represents a system of hierarchy. "Li Ding system", the etiquette system of the Zhou Dynasty stipulated that the emperor used Jiuding, the vassal used seven Ding, the doctor used five Ding, and the scholar used three Ding or one Ding. In the Eastern Zhou Dynasty, emperors used Jiuding, Qing used five Ding, doctors used five Ding, and scholars used three Ding or one Ding. Ding and other accompanying bronzes, such as reeds, are all "ritual vessels". In the funeral system of the Zhou Dynasty, they were the exclusive products of nobles, while ordinary civilians were buried with daily-use pottery.
