Which floors are good for buying a house to see Feng Shui?

What feng shui problems should I pay attention to when buying a house? First, the "landscape orientation" of the building is orientation (involving lighting, personal numerology, yuan yun, year life). Second, according to different geographical locations, does the whole building have "lonely" lighting and sound? Third, choose the floor with the most "local atmosphere". Fourth, look at the indoor building structure, whether there is a lack of orientation, whether there is sun, whether there is door-to-door, studio and so on. 5. Reasonably choose and design the master bedroom, the second bedroom, the elderly room and the children's room (especially the children's room, pay attention to whether there are guns, centipedes and strong lights. Outside the window, this is related to the child's health) 6. Reasonable design, scientific house inspection (it is very important to choose a professional designer, your doors and windows can determine 50% of your feng shui, and the design the day after tomorrow can improve 50%).
