What should I pay attention to when putting Feng Shui in the office bookcase?

Placement of office bookcases: 1. The bookcase is fierce and the desk is lucky. According to geomantic omen, desks should be placed in auspicious positions, while bookcases should be placed in relatively unlucky positions in the study to suppress evil spirits in the study. Second, the bookcase should not be placed in direct sunlight, which is not suitable for bookcases; From a scientific point of view, the bookcase is placed in direct sunlight, which easily leads to the yellowing and aging of books in the bookcase due to exposure, which is not conducive to the preservation of books. Third, the bookcase should not be full of books, and it is best 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. Fourth, the height of the bookcase should not be too high, because the bookcase is too high, which will make people who study or work feel strongly depressed. 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.
