Dianmu
Dianmu is the Mother of Lightning, the partner of Leigong, shown with a mirror in each hand — the flash is her mirrors. She belongs to the later popular and Daoist thunder tradition rather than to the classical sources.
Dianmu is the clearest case in this list of a figure whose origin story is a folk aetiology rather than a classical myth: the mirrors, the coupling with Leigong and the explanation of lightning preceding thunder all belong to the popular thunder tradition, and the folktale versions of who she was before are told differently in different places. She is not a high goddess and has no independent classical cult. The planetary, zodiac, tarot and sabbat correspondences are modern Western overlays; the tradition's own frame is the thunderstorm and the thunder department.

- Modern Practice
She is approached for warning: before an illness is named, before a business fails, before a hard thing has to be said. The practice is a mirror at the altar, incense, water and salt, and the willingness to act on the warning rather than to ask for it to be cancelled.

- Mythology Summary
Dianmu is the Mother of Lightning, the partner of Leigong, shown with a mirror in each hand — the flash is her mirrors. She belongs to the later popular and Daoist thunder tradition rather than to the classical sources, and popular storytelling supplies her origin: in one telling a woman struck by Leigong by mistake and restored by the Jade Emperor to be his companion, in another a widow punished for wasting rice. That aetiology — the lightning that comes before the thunder so that people can prepare — is a folktale explanation rather than doctrine, and the earliest layers of the Chinese thunder cult do not have her.
