There is a backrest behind the sofa.
The sofa is best placed against a solid wall, and the back can't be a door or a passage. Relying on feng shui means backing on mountains, so there is no worries. If there is really no solid wall behind the sofa due to the limitation of apartment type, you can put a low cabinet or screen behind the sofa as an "artificial backer", which can also play a remedial role.
Put Ji on the sofa.
Sofa is the focus of a family's daily sitting and lying. If you put it in Kyrgyzstan, the whole family will be infected with this position. For Dongsi House, due east, southeast and north and south are four auspicious directions, and other apartment types can refer to the diagonal direction of the living room door of 45.
The sofa should be u-shaped.
Putting the sofa into a concave U-shape, which is called "air-collecting position" in geomantic omen, has the function of hiding wind and gathering gas, and can gather money, which is more beneficial than putting it in a straight line.
Avoid facing the door on the sofa.
If the sofa is placed in front of it, it is called "hedging" in Feng Shui, which will separate the family and disperse the money. In this case, you'd better move the sofa. If it is really unavoidable, a screen should be placed between the door and the sofa.
Protect wealth from loss. It doesn't matter if the sofa faces the door. Sofas should be kept clean and tidy.
The mess around the sofa will produce evil spirits, even in the financial position. A messy sofa will affect the owner's economic ability, so be sure to keep the sofa and its surroundings transparent and refreshing.
Don't "turn your back" to the mirror when placing the sofa.
There must be no mirror behind the sofa! If there is a mirror behind the sofa, people sitting on the sofa can see the back of the head reflected by the mirror, which is extremely bad from the perspective of geomantic omen. If the mirror is around, it doesn't matter as long as the back of the head is not reflected by the mirror.
