The document summarizes the discovery of the earliest Chinese writing system found at Anyang dating back to around 1200 BC. Divination inscriptions were found carved on turtle shells and bovine scapulas used for rituals. Bronze inscriptions contained over 3000 characters and provided records of military expeditions. Other writings were discovered on bone, stone, and jade artifacts. The writing system was used for administrative record keeping and connected several cities. While the exact origin is unknown, hypotheses for its emergence include stimulus diffusion, development from clan signs, or sudden invention of a full system.
