What's the point of planting trees on the balcony?

There are big trees in front of the balcony, which will block the entry of yang and make it easy for yin to enter the house. From the geographical and natural point of view, trees are also vulnerable to the danger of lightning strikes. Therefore, when adding a green environment to the home, we must be careful not to plant plant varieties that are easy to become trees in front of the balcony.
