Why shouldn't there be big trees in front of and behind the house?

There shouldn't be a big tree in front of the house. The reasons are as follows: first, tall trees will block doors and windows, so that sunlight cannot enter the house, making the house dark and humid, and indoor moisture and turbidity cannot be removed as soon as possible, which is not conducive to the health of residents. Secondly, the roots of big trees have strong growth ability and absorb a lot of water, which is easy to destroy the foundation and affect the safety of houses to some extent. Thirdly, the big tree in front of the door blocks people's sight and limits residents' vision and thinking. In addition, according to Feng Shui, there are big trees in front of the door, which is a sign of trouble. Therefore, there should be no big trees in front of or behind the house.
