Regarding house feng shui, I heard that a big tree in the backyard of a house is not good for feng shui, and it is still very bad.

This statement has no scientific basis and is not consistent with the principles of Feng Shui.

Feng Shui believes that large trees in the backyard of a house may affect the ventilation and lighting of the house, thereby affecting the fortune of the house. However, this statement has no scientific basis, because the fortune of a house is affected by many factors, including the fate of the person, the fortune of family members, the geographical location of the house, etc.

Therefore, we should treat the feng shui of the house rationally and not be overly superstitious. At the same time, if there are large trees in the backyard of the house, appropriate methods can be taken to improve them, such as pruning branches, removing large trees, etc., to avoid adverse effects on the fortune of the house.
