What does it mean to call Chen Jia a dead man in Feng Shui?

Summons up evil spirits. In ancient times, we paid attention to where and when there were evil spirits. This is because of the limitations of the ancient world outlook and outlook on life. The predictions of various schools in the modern Book of Changes have proved that heresy is unreasonable and most of them can be abandoned. So don't care too much. Just like Hou's cross talk, when you go out, you must look at the calendar. There are bad things in the imperial calendar every day, don't go out?
