1. The color of the sofa needs to be determined according to the direction of the door. If the color is wrong, it will easily conflict with the aura introduced by the door: if the door faces east, avoid white; if it faces south, avoid yellow; if it faces west, avoid yellow. Red; facing north, avoid green.
2. Secondly, the shape of the sofa is best to form an "encirclement", so that there is a "hall" in front of the sofa to gather energy and wealth.
3. Generally speaking, the purchase of a sofa should be determined based on the size of the home, the decoration style, and the number of people in the home. It is not advisable to buy a set and a half of sofas, and it is not advisable to buy square or round sofas. When using a sofa together, it is not advisable to choose a sofa that is too bright red and eye-catching, as it can easily arouse irritability and anger in the family.
