if it's a peony with big flowers and a landscape painting, it's suitable for hanging on the wall behind the sofa. There is a "backing" behind it, and there is a "wealth".
don't hang calligraphy on the back of the sofa or seat, and don't "recite the words". But it is best to have calligraphy in the room, and it is best to hang it on the front of the sofa, that is, on the top or side of the TV.
The conclusion is that four screens with bamboo and chrysanthemums should not be hung on the TV wall, that is, opposite the sofa. It can be hung on an idle wall. If the room is big enough, it can be placed on the wall on the side of the dining table. Or the side wall of the living room.
the above is for reference only. Please criticize and correct me!
