What are these things collectively called oracles?

Oracle Bone Inscriptions or Oracle Bone Inscriptions refers to the written records carved on the bones and carapace of cattle scabbard, tortoise shell and other animals by wizards in the late Shang Dynasty, and also refers to the compilation compiled by modern scholars.

Oracle Bone Inscriptions in Oracle Bone Inscriptions is far from modern Chinese characters, so it is difficult to read and understand. Ancient Chinese characters, archaeologists, etc. I explained this and compiled the unearthed Oracle Bone Inscriptions with Oracle bones into a book. A complete Oracle Bone Inscriptions consists of four parts: preface (recitation, narration), destiny (chastity), occupation and confirmation, with different engraving times.

The preface records the divination time and asks the divination name of the gods, which plays a narrative role, so it is also called narration and narration. Life words record specific divination matters and ask questions to the gods, which is also called advice. What Jenci recorded was the result of divination, which was the answer given by the wizard based on the analysis of the cracks in the bone nails.
