Not good! Although the coffin is a funeral object, it is regarded as a mascot by Feng Shui, and many gift shops also sell exquisite coffin models as auspicious ornaments. The financial and official positions that should be placed in the house mean that the owner of the house can be promoted to a higher position and make a fortune.

There is always a place to put excess garbage under the stairs.
