What archaeological discoveries in the Central Plains can prove the mythological records in ancient books?

China's ancient books, which record myths, are now the most recognized by academic circles. One is Shan Hai Jing, which is a record of geography and hydrology on the one hand, and a copy of early local myths and religions on the other. Second, Historical Records, because China had no writing before Shang Dynasty (or cultural relics that can prove the existence of writing), many contents in the history of the Three Emperors and Five Emperors and the Xia Dynasty recorded in Historical Records are actually myths passed down from mouth to mouth.
