People in China have always believed in Feng Shui. Tigers are wild animals and should not be placed on the balcony. Balcony is suitable for planting flowers and plants, and the air humidity in modern buildings built of reinforced concrete precast slabs is far below the normal standard, which is similar to that in the desert. And a plant called sedge can turn "desert" into "oasis". Cyperus likes water, so potted Cyperus should be put in a deep sink. Many flowers and plants suitable for indoor planting have sterilization function. If you put some potted oranges, rosemary, peach trees and chlorophytum indoors, the bacteria and microorganisms in the air will be greatly reduced. People will feel suffocated in a stuffy room. The reason is not the lack of indoor oxygen, but the lack of negative oxygen ions. When there is a TV or computer running indoors, negative oxygen ions will decrease rapidly. There are many plants that can be planted indoors that can produce negative oxygen ions-these plants are cypress, arborvitae and cedar. If the indoor area is too small, you might as well change varieties and plant some low plants, such as cactus.
These are some suggestions for balcony placement. If you find it helpful, please pay attention to the author and adopt it.
