Bronze is the product of the great development of smelting and casting technology in ancient China, and it was the luxury of emperors and nobles at that time. Bronzes are mostly from Zhong Ding, so the bronze inscriptions are also called Zhong Dingwen. The application of bronze inscriptions lasted for more than 1200 years from the early Shang Dynasty to the Qin Dynasty's destruction of the Six Kingdoms.
