The Shang Dynasty ruled from around 1500-1100 BCE during the Bronze Age in China. They developed advanced bronze metallurgy techniques like piece-mold casting to produce ritual vessels. They also created one of the earliest forms of Chinese writing through oracle bone inscriptions used for divination. An important Shang site was discovered at Yinxu containing remains of palaces, tombs like that of Fu Hao, and thousands of oracle bones providing evidence of their advanced script and bureaucracy.
