1. There should not be a mirror behind the sofa
There should not be a large mirror behind the sofa. When people sit on the sofa, others can clearly see the back of the person sitting in the mirror. Not good. And if the mirror is nearby but not behind, it doesn't matter if the back of the head is not reflected in the mirror.
2. Avoid beams pressing on the top of the sofa
If the bed has beams pressing on the top, only one or two people sleeping on the bed will suffer. However, if there are beams pressing on the top of the sofa, the hands will be affected. It affects a large family, so it must be avoided as much as possible. If it is really unavoidable, you can place lucky bamboos on the coffee tables on both sides of the sofa to relieve the pressure on the beams with the lucky bamboos that continue to grow and rise step by step.
