What can Feng Shui master use instead of cinnabar?

Cinnabar is a kind of red mineral pigment, which was used by ancient emperors to write annotations when marking and commemorating, and Buddhists often used cinnabar as an ornament. Because the ancients thought that this kind of ore had been buried underground for thousands of years, it had already absorbed the essence of the sun and the moon and had aura, so the geomantic effect of cinnabar was irreplaceable by other things. You can try to buy it in a Chinese medicine shop, because cinnabar is still a Chinese medicine for calming the nerves, and Chinese medicine shops may have it.
