God is also called "Emperor", "God" and "Heaven" in Oracle bone inscriptions of Shang Dynasty and Zhou Dynasty.
In Confucian classics, another title equal to heaven is God, or proclaimed emperor, Emperor of Heaven. The name of the Emperor of Heaven comes from Zhao Gao Shangshu: "The Emperor of Heaven changed Yuan Zi, and the life of Yin Daguo." "Shangshu Shundian": "Four categories belong to gods, only six grids, mountains and rivers, all over the gods."
