The appearance of Oracle Bone Inscriptions was also confirmed, but Oracle Bone Inscriptions was mainly used for divination and recorded the divination contents. Formal politics, economy and culture are mainly recorded in bamboo slips and wooden slips, but these materials are not easy to preserve and books are destroyed by war, so few bamboo slips and wooden slips have been unearthed in China so far.
