Similar to the family emblem, it is a family pattern, which is the symbol of a family. The early family lines were only used for identification. With the passage of the times, the types gradually increased, and the family lines also became more complex from simple, leaving various influences in various times. Heraldry refers to a kind of colored sign which is formed according to specific rules and belongs to an individual, family or group. In medieval Europe, there was its own coat of arms system, also known as coat of arms, which was born on the battlefield in the 12th century, mainly to identify knights who could not be recognized because of their armor. The general view that heraldry is a noble patent comes from this. Since the 13th century, anyone, whether noble or civilian, can own and use heraldry as long as they abide by the rules of heraldry. Up to now, it is a science and art to identify the use, display and rules of hereditary or inherited marks of individuals, military units, government organizations and companies.
In the early Western Zhou Dynasty, the inscriptions of clan names were common on Chinese bronzes and a few other artifacts, and their clan names were often pictographic, so they were called "clan emblems". Due to the universality of the use of the family emblem and the primitiveness of the early characters, there is no essential difference between the early family emblem and the characters. The family emblem is not only the image symbol of the family, but also the title of the family. If the family has a vassal state, it can also be used as the name of the vassal state. However, the use of family emblem and surname is not exactly the same. As a symbol of the family, the family emblem is cast on bronze wares, used in bronze inscriptions, or inlaid on the family flag and the armor of family members, which highlights the image. The surname is mainly used for daily address, and it needs to be able to read and write. As a result, with the evolution of characters, characters and symbols that are easy to write, have pronunciation and have the same meaning as the original meaning of the national emblem have gradually emerged. Because of the rapid evolution of characters, while the national emblem deliberately maintains the ancient image, the two have evolved in different directions for a long time, and the differences between them are getting bigger and bigger. After Qin and Han Dynasties, surnames, surname and one. This is why surnames, surnames and family emblems can be found in bronze inscriptions, and it is not easy to directly compare surnames and family emblems. In Japan, the national emblem, as a symbol of a family, is highly valued. Generally, only men wear the national emblem and it will be embroidered on the chest of clothes.
