Long ago before the introduction of Buddhism from India and the advent of Daoism and Confucianism, the Chinese believed in Shang Di, a God so great that no images were to be made to represent it and the one true God who made the heavens, the earth, and all that is in both.
These inscriptions read 皇天 上帝, or "Heavenly Sovereign Shang-di", with its equivalent translation in Manchu on the left side of the tablet. Although the Manchurians were a small minority in China, they somehow managed to overthrow the Ming 明 Dynasty to establish the Qing/Ching 清 Dynasty. The Manchurians were not Chinese, yet they acknowledged Shang-dias the Supreme God of the Universe.
