Does the sofa in the middle of the living room have an influence on Feng Shui?

There is a saying in Feng Shui that there is a backer, and the sofa in the living room should be placed next to the solid wall. Hanging in the air is not good, and there are mountains to lean on. With the help of noble people, the future is infinite. The sofa next to the solid wall means no worries, and sitting against the wall can also give people a sense of psychological security. The chairs used in the ancient imperial court were all made of natural marble as a backup, which is a geomantic truth. Therefore, if your sofa is in the middle of the living room, it is recommended to set a screen behind the sofa, so that the sofa is reliable.
