Shang and Zhou dynasties mainly refer to the artifacts made of copper-tin alloy in the pre-Qin period, referred to as "bronzes" for short. Including cookers, food containers, wine containers, water containers, musical instruments, chariots and horses ornaments, bronze mirrors, hooks, weapons, tools and weights and measures. Popular in the late Neolithic period to the Qin and Han dynasties, Shang and Zhou artifacts are the most exquisite. Gadgets or decorations appear first. There were bronze containers and weapons in the Xia Dynasty. In the middle of Shang Dynasty, the varieties of bronzes were very rich, with inscriptions and exquisite patterns. From the late Shang Dynasty to the early Western Zhou Dynasty, it was the heyday of bronze ware development, with diverse shapes, rich inscriptions and rich patterns. Subsequently, the bronze matrix began to thin, and the decorative pattern gradually simplified. From the late Spring and Autumn Period to the Warring States Period, due to the popularization and use of iron tools, copper tools became less and less. During the Qin and Han dynasties, with the introduction of porcelain and lacquerware into daily life, the variety of copper containers decreased, the decoration was simple, most of them were plain, and the carcass was light. Ancient Chinese bronzes are the great contribution of our ancestors to human material civilization. Although according to the current archaeological data, Chinese bronzes appeared later than some other places in the world, there is no place in the world where bronzes can be compared with ancient Chinese bronzes in terms of scale of use, casting technology, plastic arts and varieties. This is one of the reasons why China ancient bronzes occupy a unique position in the history of world art and attract widespread attention.
