Feng Shui believes that there are big trees in the backyard of the house, which may affect the ventilation and lighting of the house, thus affecting the fortune of the house. But this statement has no scientific basis, because the fortune of a house is influenced by many factors, including the fate of people, the fortune of family members, the geographical location of the house and so on.
Therefore, we should treat the house geomantic omen rationally, and don't be overly superstitious. At the same time, if there are big trees in the backyard of the house, appropriate measures can be taken to improve it, such as pruning branches and removing big trees, so as not to adversely affect the fortune of the house.
