There is a gossip mirror in my son's room, and he often has nightmares at night. Does it have anything to do with the Eight Diagrams Mirror?

It mainly depends on where the Eight Diagrams mirror is hung, the orientation of your son's room and his birth date and zodiac attributes, all of which are quite particular.

Of course, don't just stand on the side of the road and be fooled by a feng shui master. Ask the older generation. Anyone who knows something about Feng Shui will come and have a look.

Let my son get up early, go to bed early and do more exercise. It is healthier to bask in the sun. Definitely more reliable.
