Yang Gui in the Yellow Calendar

The role of yin ghosts and yang ghosts is closely related to the status of nobles. It's expensive during the day and at night, or expensive at night, neither expensive nor expensive. Yang Guifei is in Yang's position, just in her prime, sailing with the water. Yin is in the yin position, just as things are upside down, sailing against the current, and God hides Jaken chaos; Yang is more valuable than Yin.
