The evolution of bronzes from Xia, Shang and Zhou Dynasties to the Spring and Autumn Period is mainly divided into changes in ornamentation, shape and inscription. 1. The decorative patterns of bronzes in Xia, Shang and Zhou Dynasties include gluttonous patterns, thunder patterns, string patterns, fish patterns, bird patterns and turtle patterns. The decorative patterns of bronzes in the Spring and Autumn Period include dragon and snake patterns, animal patterns, deformed animal patterns and wave patterns. 2. Bronzes in Xia, Shang and Zhou Dynasties are small tools or decorations. There were bronze vessels and weapons in the Xia Dynasty. There are many kinds of bronzes in the middle of Shang Dynasty, with inscriptions and exquisite patterns. From the late Shang Dynasty to the early Western Zhou Dynasty, the development of bronzes was in its heyday, with a wide variety of vessels, solemn inscriptions and rich patterns. In the Spring and Autumn Period, pots first appeared, and then oval cups; There are pots, chopsticks, pots and bronze musical instruments in the middle platform; The shape of late bronzes is complicated, and the objects used in different areas are different, while in some areas, few are found and the situation is not clear.

3. Bronze Inscriptions in Xia, Shang and Zhou Dynasties In view of the development stage of bronze inscriptions, and the classification of bronzes is mainly based on shape and decoration, bronze inscriptions will have some fashionable and contemporary styles. In the early Spring and Autumn Period, there were few bronze inscriptions, and most of them were records of wedding utensils and self-use utensils of princes and doctors. There is no obvious change in the style of dictionaries in Ming Dynasty. In the late Spring and Autumn Period, the inscriptions on bronzes mostly recorded their own utensils, and the inscriptions were generally in a certain format. The content always shows the family, status and identity of the master's utensils, and boasts the beauty of morality, and there are also a few inscriptions to record the wedding. There is not much related to historical materials except that the names of the prince or doctor Qing can be verified through historical books and some people who have historical books to test. This is because the social function of bronzes changes with the times.
