What does it mean to install lights on the pillars of the roof? What feng shui array is it?

If the pillars of the roof protrude, it will hinder the air flow and form a gas trap. This is the principle of beam coping. The best way is to flatten the roof when decorating. If not, install lights next to posts or beams and turn them on frequently. After heating, it will block the surrounding gas field, which is equivalent to adding an air wall to solve the beam coping, but this method is impossible. The light is on all the time, and the wind wall can't completely block the airflow, so it can't be completely solved. It's best to level the roof or avoid the beams. I wonder if the pillars on the roof are coping. If so, that may be the reason. If not, it may be just for beauty or other reasons. I hope I can help you.
