First of all, let's sort out the problem of big trees at the door, which is also flawed in geomantic omen. The door is the vent of the whole house, and only through this port can good air be introduced. For example, it was blocked by a big tree, the ventilation was not good, Yang Can couldn't get in, Yin Qi couldn't get up, and the sun covered it, making the room damp, so it was fierce. Don't let too many branches touch the roof, which will affect the ventilation and sunshine and make the house wet.
There is a mirror hanging on the door, and it is generally believed that there is a sense of suffocation around the house. However, in feng shui, this practice is actually not good, but it will have the opposite effect. In life, we often see a mirror hanging on the door or balcony of a family. It has different sizes and different appearances, but it is considered to have the same effect: to ward off evil spirits from the right place to evil spirits. This is especially true in many rural areas. According to experience, people who live in houses with mirrors on the doors often get sick or have headaches or dizziness.
Mirrors are one of the necessities in our lives, which the ancients thought were women's things. It can ward off evil spirits and attract evil spirits. Mirrors are also commonly used in folk geomantic omen, but you can't hang a mirror on the door. If you hang it incorrectly, it will not improve Feng Shui, but will destroy it. To sum up, it is from the perspective of feng shui.
