What's the point of putting geomantic omen in bookcases in small rooms?

1, the bookcase should not be full of books, so it is better to leave some space for "ventilation". From the perspective of furniture maintenance, if the bookcase is full of books for a long time, it will easily lead to the deformation of the bookcase; From the perspective of bookcase feng shui, bookcases full of books are not "breathable", which makes people feel irritable and lack inspiration.

2, the height of the bookcase should not be too high, because the bookcase is too high, which will make people who study or work have a strong sense of oppression. It is easy to make people feel dizzy and uneasy for a long time, which is not conducive to study and work, so it does not conform to the bookcase in the study of Feng Shui.
