The sofa is not against the wall. Is there such a sentence in Feng Shui?

No, there is no saying. The sofa doesn't have to be placed against the wall. According to the layout and beauty of the house, it can be placed anywhere, as long as it is convenient for you and does not interfere with others, as long as you sit comfortably. In fact, there are not many things related to feng shui in life. Don't associate everything with feng shui.
