Lei Gong, the Thunder Duke, is a thunder deity in Chinese religious and mythological traditions. Early thunder-spirit descriptions and later Lei Gong images differ.
The Story Behind Lei Gong and early thunder spirit
The Shan Hai Jing, Hainei dong jing, describes a thunder spirit at Leize with a human head and dragon body, beating its belly.
Later folk iconography can show Lei Gong with a beaked face, bat-like wings and drums, as described in Werner’s 1922 retelling.

Different thunder-spirit representations
These are different representations; wings and a ring of drums should not be assigned to the early Leize passage.
The illustrations distinguish the later winged Thunder Duke from the early human-headed dragon-bodied thunder spirit.
