These floors are called the most ideal floors, which not only have better lighting and brighter vision, but also don't have to worry about the influence of external noise and automobile exhaust on the house. In addition, the most important thing is that these floors do not belong to the floating dust layer, so there is no need to worry about adverse effects on residents' body and mind.
When choosing the floor, we should also pay attention to the order of fire and gold, Jin Kemu, Mu Ke Tu, Tu Ke Shui, and Water Ke Huo. It is more complicated to combine a family's five elements with the floor feng shui. When it is impossible for people who belong to the water to live in the water building, they should try their best to choose favorable floors, but seek to maximize the collective interests.
So, it depends on what you like.
