Which divination was it before the invasion of Yin? Do any historians know?

According to the records in Historical Records of Qi Taigong Family, I only know that this time it was "the writing on the wall, the storm is coming", but Jiang Shang strongly advocated sending troops, which eventually ruined the business. 、

Therefore, this kind of divination is not calculated by gossip, but by burning tortoise shells to investigate the cracked texture, which is now Oracle Bone Inscriptions discovered in Shang and Zhou Dynasties. Sometimes the process and results of divination are engraved on tortoise shells, which is Oracle Bone Inscriptions.
