There must be no mirror behind the sofa. People sitting on the sofa, others can clearly see the back of the head of the sitting person from the mirror, which is not good from the perspective of geomantic omen. But if the mirror is around, as long as the back of the head doesn't reflect from the mirror, it's okay.
3. Don't face the door on the sofa. If the sofa and the living room door are placed in a straight line, it is called "hedging" in Feng Shui, which has great disadvantages and will cause family members to be separated and money to be exhausted. In this case, it is best to move the sofa to another position. When there is no other way, we have to put a screen between the door and the sofa to prevent the air flowing out of the door from rushing straight to the sofa, to protect the wealth from leaking out and to reunite the family. If the sofa is placed towards the door, the problem is not big, and there is no need to put a screen to solve it.
4, the sofa is the most taboo beam coping. Whether in the living room, bedroom or kitchen, the top of the beam is a taboo. If there is a beam directly above the sofa, which belongs to the top of the beam, it has a great influence on the people sitting below and must be avoided. If you really want to put it under the beam, you must put two pots of lucky bamboo on the coffee table on both sides of the sofa to bear the pressure of geomantic omen.
