First of all, from the homophonic point of view, 16 floor is more auspicious, but this is only an unscientific statement, mainly because I don't care. From the point of view of realistic science, which of the three layers is better depends on the total number of layers. If it is 30 floors, according to the choice between 1/3-2/3, the floors between 15-20 are better, and the lighting and ventilation conditions of these floors can be guaranteed.
In addition, factors such as lighting, sunshine, ventilation, surrounding environment, family members and personal circumstances should be considered comprehensively when choosing. Sometimes the choice is not only based on the number of floors, but also on the actual situation at home.
Taboo layer number
Most people will consider whether the numbers are auspicious when choosing a house. Most people avoid floors with 4 when buying a house, such as the 4th floor, 14, 24th floor. This is mainly because the number "4" is homophonic with "death". After adding "1", "14" is "Yaosi", which is roughly equal to "death".
If you add "2", "24" means "the death of a child", which is very unlucky, so many people are taboo. From ancient times to the present, it is a taboo in China folk culture.
