Solution 1: hang a convex lens, eight diagrams mirror or five emperors' money at the door. A convex mirror, like a tortoise shell, has a reflective function. When evil things rush in, the convex mirror can reflect them. As the name implies, the Eight Diagrams Mirror is eight kinds of fields corresponding to eight kinds of images. Among them, Taiji diagram condenses the information of cosmic balance, which can resolve the influence of gas field transformation and remove the adverse terrain from itself. Of course, hanging a mirror will still affect the fortune, and good luck may also be reflected away, while the five emperors' ancient money can avoid negative effects. By improving the popularity of their own geomantic omen, we can better resolve the evil spirits of geomantic omen, especially the classic geomantic omen items such as Five Emperors Money. This Taoist design is more effective. So this method is the best.
Secondly, putting a pair of stone lions at the gate and then wrapping the trunk with gold paper can also solve the problem of trees at the door, but it is not as convenient and effective as the above method.
In addition, it should be noted that there are no dead trees in front of and behind the house, except big trees. Even a small dead tree will have adverse effects, because the tree itself is heavy in yin and will block the entry of yang, especially the elderly at home, which is more likely to lead to family disharmony.
