Zeus had seven wives, namely Metis, themis, Eurynome, Demeter, Monnemo, Leto and Hera. Among them, only the seventh Hera was named "Tianhou".
Because when Zeus proposed to Hera, he promised to share his power and honor with Hera, and Hera, as the ruler of Olympus, always accompanied Zeus and helped Zeus defeat Cronus to become the third generation king of gods.
The legend of Zeus:
After the great victory in the Battle of Titan, Zeus and his brothers did not give in to each other because of how to distribute the world's sovereignty, and there were many contradictions. Seeing that war was about to break out between them, Prometheus, who was full of wisdom, proposed to decide the sovereignty of the world by drawing lots.
According to the result of the lottery, Zeus was assigned to the sky and became a god. Poseidon was assigned to the sea and became the sea god, and Hades was assigned to the underworld and became Hades. As for the earth, the three brothers have negotiated. The three brothers respected Zeus who was in charge of the sky.
