From the perspective of geomantic omen, it is necessary to hang landscapes on the north wall of the living room: from the perspective of geomantic omen, it is very auspicious to hang landscape paintings, because "people are in charge of money". Usually a non-Feng Shui landscape painting is hung on the wall behind the sofa, which forms a landscape-dependent pattern with the sofa. Water represents financial resources, and flowing waterfalls represent rolling financial resources, which is very good. The mountain represents the backing, and the back is against the mountain. No matter what you do, there will be a backing, so it is very ideal to hang landscape paintings in the living room.
I hope it helps you.
