Extended data:
Generally speaking, Nanhong is not suitable for sleeping, because Nanhong has a cool touch, which easily affects the quality of human sleep. From the perspective of geomantic omen, sleeping in the same room, in particular, is disrespectful to the gods, so that Nanhong can have a certain rest, so as to exert the greatest effect.
At the same time, from the perspective of feng shui, Nanhong is spiritual, and it is best to take it off when sleeping or taking a shower. Because it is worn for a long time, Nanhong absorbs more negative energy for the wearer, and needs a certain degree of rest to play its greatest role and avoid disrespect to the gods.
