What are the feng shui taboos for planting trees in villa courtyards?

According to the ancient geomantic theory, osmanthus trees and magnolia trees can be planted in the front yard of Chinese villas, which means wealth and good luck, phoenix trees, and locust trees, which means shade and future generations; Planting pomegranate trees in the backyard means that children and grandchildren are full, and the days are thriving and thriving. But planting trees with high crowns in the yard needs to be arranged reasonably. Geomantic speaking, the tree is "yin", and the gathering of yin is not conducive to the villa yard. So when planting tall trees in the yard, part of the crown must be thrown out of the wall. In addition, although the willows are not big, they are also cloudy and should be far away from houses.
