What is the belief in Mongolia?

The god of Mongolian national belief is called "eternal heaven", which means "heaven".

Since ancient times, Mongolia has regarded "Tian" as the eternal supreme god, so it is called "eternal Tian" (pronounced "Tengger" in Mongolian).

In the Mongolian people's own mode of thinking, the supreme power is granted to a leader on the ground by the god of "eternal heaven" (that is, the god of nomadic tribes on the grassland).
