U shape placement
The sofa in the living room is like a national port, and the decoration should be curved rather than straight. It looks like the word "U", which means that the wind gathers gas and the wealth is prosperous. Avoid straight row, like a strong man with a broken arm, which is not conducive to home feng shui.
Solid walls are ideal.
It is advisable to rely on the back of the sofa, and the solid wall is the most ideal. If there are windows, doors or passages behind you, you will feel empty and insecure. If really helpless, you can put a low cabinet or screen as an "artificial backer."
Avoid water element
Don't put the fish tank behind the sofa, because water is not conducive to feng shui behind the sofa. Similarly, water ornaments such as fish tanks on low cabinets need to be cautious. However, it is a good choice to fill the back space with evergreen plants.
Avoid big mirrors
Finally, don't have a big mirror behind the sofa. When sitting on the sofa, if the mirror can reflect the back of the head, it is not conducive to Feng Shui. So, make sure the mirror is not behind the sofa, but beside it.
