Nowadays, when decorating a new house, people like to make a shelf to show the owner’s hobbies and accomplishments. In fact, this is contrary to Feng Shui, because most of the artifacts placed on the archaeological shelves are cultural relics with a long history or obtained from tombs. Because these things are basically funerary objects, personal belongings of the deceased, which have not seen the light of day for a long time, have a heavy yin energy, and are attached to the deceased's information. It will have a direct impact on people's health, wealth, accidents, etc.
You can place other prosperous things on the Bogu rack.
