If you have a courtyard at home, it is best not to have a single big tree inside the wall. Because the tree is too big and stands alone, and the house is often in the shape of the word "口" due to the courtyard, the two combined into one look like the word "trap". In Feng Shui, it means that the residents are more likely to know dragons. If you are trapped in a shallow situation, your abilities cannot be used, and it is difficult to achieve success. Trees suitable for planting in the courtyard should not be too large.
The most fundamental method is to cut down the trees and plant them instead with ornamental plants with auspicious meanings. If trees need to be planted in the courtyard due to design reasons, it is recommended that residents plant fir and cypress. In the wooden buildings of the past, fir and cypress were often used as pillars. Here we can take their beautiful meaning of "the talents of pillars".
