In Chinese mythology, Lei Gong (雷公) is the god of Thunder.

This god started off as a mortal. He encountered a peach tree that had come from Heaven, due to the struggle between the Fox Demon and one of the Celestial Warriors , and had become evil. When Lei Gong took a bite out of one of its peaches, he was turned into a human with bird wings. He soon received a mace and a hammer that could can create thunder. This is how he became the God of Thunder. Lei Gong is said to be extremely prudish, and will not enter a house where copulation is taking place. Pictures of this act are also supposed to have the same effect.
