2, the sofa is best placed against the wall, not facing the passage, not behind. From the perspective of geomantic omen, it is carefree to have a backer against the wall. If there are doors, windows and passages behind the sofa, and there is no wall to lean on, it will form a loose situation and people and money will be hard to prosper. The remedy is to put furniture such as screens and low cabinets behind the sofa to artificially create a backer. Things are a little better.
3, the sofa is most afraid of the top of the beam. Whether in the living room, bedroom or kitchen, the top of the beam is a taboo. If there are beams on the sofa, the influence will be great, so we must avoid them. 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.
