After divination, the time of divination, the name of the diviner and the things divined are engraved on the side of divination with a knife, and some even engrave the good and bad luck that will come true in a few days. Scholars call this kind of record Oracle Bone Inscriptions, and this kind of writing is Oracle Bone Inscriptions. Oracle Bone Inscriptions was found in Xiaotun Village, Anyang, Henan Province, and it is a relic of Shang King Pan Geng who moved to Yin and died in China. Later, it was also unearthed in the Shang Dynasty sites in Zhengzhou and Luoyang, and Oracle Bone Inscriptions in the Western Zhou Dynasty was also found in the sites in Changping, Beijing and Joo Won?, Shaanxi.
