To ensure that disharmony amongst siblings (brothers and sisters) doesn’t happen, one has to make sure that children’s/ siblings’ doors don’t open to a long hallway. If all the bedrooms of the siblings open to a long hallway, this symbolizes too many ‘mouths’ trying to get or release chi. If this happens, it will surely make a lot of fighting and will create a major disharmony amongst siblings.
To counter this Feng Shui blunder, you can put paintings on the wall of the hall, plants, and big crystals. The remedies will work to regulate the flow and balance all the ‘mouths’ eating and releasing chi.
