2. Take it off in the shower. Many people wear ornaments made of Buddha cards or cinnabar with them to protect peace and ward off evil spirits. Because cinnabar is full of yang, it can drive away objects with heavy yin. However, if you wear cinnabar ornaments, you'd better take them off in the shower. Although cinnabar is insoluble in water, it will be disrespectful to Buddha statues and gods, which is likely to affect the effect of exorcism.
3. Do not open the cinnabar in the cloth bag. Old people are sometimes forgetful or uneasy, so they can wrap cinnabar in cloth and put it in the room to soothe the nerves and exorcise evil spirits. But this kind of cloth bag can't be opened casually, and the effect will be greatly reduced after opening. Or some people go to places with heavy yin, such as graves, and take cinnabar with cloth, and try not to open it.
