Cinnabar is pure yang. It can be placed at home to enhance the positive magnetic field at home, and of course it also has certain effects. But if it is in the hands of ordinary people, the effect will be greatly reduced. If it can be used, such as painting or thunder writing, it will all be restored. It is likely to affect the effect of the monarch. Don't open the cinnabar in the cloth bag. Sometimes old people are forgetful or uneasy. You can wrap cinnabar in cloth and put it in your room to calm your nerves, but that's it.
