In fact, this custom is very simple. Bamboo is not planted in front of the residential building in front of the door. In fact, it is based on the real living environment. Mainly according to local customs and personal habits, if bamboo is planted in front of the door, it will block the sun because it is tall and evergreen all the year round. As a result, the room is dark, and even the humidity is particularly thick, which is easy to attract some snakes and mice, affecting the living safety and environmental sanitation.
Houses in China generally face south. This design contributes to the brightness of light when it passes through houses and rooms. However, if trees are planted in front of the room, with the growth of trees, most of the sunlight will be blocked, which is not conducive to the lighting and ventilation of the room. In some areas, rooms even become dark and humid in autumn and winter, which is not good for people's health. So in order to improve the permeability of the house, it is not suitable to plant trees in front of it!
The ancients didn't plant those big trees behind the house. After all, their roots are thick and can reach several meters underground, which will cause some damage to the foundation of the house. Maybe a slight earthquake will cause the house to collapse. When the rainstorm comes, the house will be unstable because of the rain, which will also increase the danger. In addition, when stormy weather comes, branches are easy to break, which will cause some damage to the roof.
