The Goddess of Lightning, also called Dian Mu in Chinese, is a supernatural being that has magic power and is in charge of lighting in the heaven. It is said that she is the wife of the God of Thunder. She is viewed as the symbol of justice as she can distinguish good from evil and uphold justice.
The history of the Goddess of Lightning can date back to the period of Song Dynasty (960~1279). In ancient China, the image of the Goddess of Lightning was often depicted as a kind and elegant woman. She has two lightning mirrors, which can help her look carefully whether the person is good or evil.
There spread a legend about the Goddess of Lightning. The legend goes that, in ancient times, there was no lightning during the thunderstorm. One night, the God of Thunder killed a good woman by mistake. He blamed himself for a long time. Then he told the Jade Emperor about this woman. Jade Emperor also commiserated with the woman and conferred the Goddess of Lightning on her. From then on, the God of Thunder and the Goddess of Lightning worked together to chase away the evil spirits and punish the criminals. In order not to kill the good people, the Goddess of Lightning would use her mirror to judge first and then the God of Thunder will make thunder to punish the evil. Therefore, we can always see a flash of lightning before hearing the thunder during the thunderstorm.
