Because cinnabar is a magnetic field with strong yang, and ghosts or evils are extremely yin, cinnabar can suppress them. So why is cinnabar a magnetic field with strong yang? This is mainly because in geomantic omen, cinnabar is collected in the vein that passes through the essence of the sun and the moon. Because it absorbs the righteousness of heaven and earth, it has a very strong magnetic field. In addition, cinnabar feels warm in the palm of your hand, which is different from the cold feeling of jade and jade beads in your hand. Therefore, cinnabar is often called a magnetic field with strong yang.
