Precautions:

In geomantic omen, cinnabar is derived from the essence of the sun and the moon, and has a strong magnetic field because it absorbs the righteousness of heaven and earth. The difference between cinnabar and jade and dzi beads is that it is cold in hand and warm in hand, that is to say, cinnabar is a strong yang magnetic field.
