What is the meaning of "evil spirits" in Feng Shui?

The "evil spirits" in Feng Shui is a general term, and it is also a title of Feng Shui master's unfavorable factors to residential feng shui. "Stupidity" can be generally divided into three types. One: the "evil spirits" that can be seen or even touched. Such as: corners, road bumps, iron towers, telephone poles, chimneys and other poorly shaped objects. Two: the invisible "evil spirits" of flying stars. That is, four unfavorable flying stars in Jiugong. 1: Erhei Giant Gate is a symptom, and the five elements belong to the soil, which is the main disease and epidemic. 2. Lu Xing is a three-garden, and the five elements belong to wood, and the main tongue is arguing. 3. Huang Wulian's revitalization, the five elements belong to the soil, and the main evil. 4: Seven Red Broken Army Stars, Five Elements Belonging to Gold, Main Disaster Injuries Thieves, and Official or Technical Disasters. The above four kinds of "evil spirits" of flying stars are generally reflected by something wrong. Their influence is different, all because they have a containment relationship with other flying stars and have produced new changes. This change will make one's "evil spirits" stronger or weaker. Three: the fierce combination of regulating qi and chaos. In fact, it is a specific evil produced by the combination of the former two. On the whole, this fierce influence is still quite great. This "evil" generally appears in the direction of the doors and windows of the house, because only these two directions are connected with the outside world, that is, only these two places receive the air and sunshine outside the house. If the messy head outside the house or the sharp corner inside the house and other unfavorable things and ramps rush to the door or window inside the house, it will naturally constitute an outdoor fierce. At the same time, when the combination of flying stars in the house on the doors and windows happens to form the "evil spirit" of qi, the influence of this "evil spirit" will be even greater. Generally speaking, this "evil" is taboo. The so-called "unreasonable qi is invalid, and qi cannot be tested."
