Who was Lei Kung?
Lei Kung was the Chinese god of thunder, and his wife, Lei Zi, was the goddess of lightning. He makes thunder with his hammer, like the German god Thor, and Lei Zi makes lightning with her mirrors. Artists drew Lei Kung with a bird's head and wings and claws, and blue skin, and he rode in a chariot pulled by six boys.
