What is the Feng Shui effect of screens? Screen to ward off evil?

Screen is a piece of furniture used to block wind inside buildings in ancient times, so-called "screening the wind". The screen was originally designed specifically for use behind the emperor's throne and was called "axe". After a long period of development, screens became popular among the people, entered ordinary people's homes, and became an important part of ancient people's interior decoration.
Screens are usually displayed in prominent positions in the room, playing the roles of separation, beautification, wind blocking and coordination, combining practicality and appreciation. When talking about the Feng Shui effect of screens, we cannot fail to mention the "screen wall". In ancient Chinese courtyard buildings, there are often "screen walls" inside and outside the gate. The screen wall is set up to prevent the impact of "qi". In Fengshui, no matter it is a river or a road, it is taboo to go straight. "Water Dragon Sutra" says: "Straight coming and going will harm the population", which reveals the secret.
With a screen wall, the airflow has to go around it, which slows down the airflow speed. When the air is slowed down, it will not disperse, which conforms to the principle of "curves have emotion". In the Forbidden City in Beijing, almost every courtyard and every palace has a screen wall. The only difference is the material: either brick, wood, or jade. The screen wall slows down the incoming airflow, which not only plays a role in gathering qi, but also slows down the airflow to a speed close to the speed of qi and blood circulation in the human body, making people feel comfortable, which is of great benefit to the health and career of the residents.
This principle is applied to room design and is reflected in the use of screens. According to the "Records of the Grand Historian: Biography of Mengchangjun", "When Mengchangjun was entertaining and talking with guests, there was always an attendant historian behind the screen, who was responsible for recording what he said to the guests." It can be seen that the screens in the Spring and Autumn Period and the Warring States Period had the function of shielding; and this period was also the time when the "Huangdi Neijing", a classic work of traditional Chinese medicine with "qi theory" as its core, was written. As a product of the same era, the screen would definitely not ignore the role of "qi". Xunzi's Dalüe says: "The emperor is on the outer screen, please wait on the inner screen."
Nowadays, Feng Shui is popular all over the world. Many business people in many places, especially in Hong Kong, Taiwan, Southeast Asia and other places, also use Feng Shui in business wars. Among them, the screen played a lot of roles. For example, by cleverly using screens in the reception room, you can divide the room into several small auras that gather energy, adjust the source of the "vitality", put yourself in the most prosperous aura, and put your clients or negotiating opponents in the weakest aura.
From the perspective of Feng Shui, screens have the functions of warding off evil, bringing in good fortune, gathering energy, and providing concealment. Moreover, the auspicious patterns on it can also enhance the fortune of the residents, show the residents' qualities, and so on. In fact, among all items that can ward off evil spirits, the feng shui effect of screens is the most significant. The Feng Shui status of screens as decorative embellishments is becoming increasingly prominent, creating an auspicious and lucky atmosphere in the room. If the screen is placed properly, its Feng Shui significance can promote daily living, work and study in an immeasurable way.
Porch screens are often related to door evil spirits, and the porch screens in modern home feng shui often reflect this function. Some homes are adjacent to roads, while others are close to factories, construction sites, garbage dumps, hospitals, temples, funeral homes, etc. Such a feng shui field will naturally affect the good fortune of the door, and the function of the entrance screen in warding off evil spirits will be highlighted.
Therefore, when modern Feng Shui uses screens for people, most of the purpose is to dispel evil spirits. The function of using a screen to block sight and wind is obvious, but if you really want to use a screen to dispel evil spirits, it does have an effect, but it is still small. We know that the qi mentioned in Feng Shui, whether it is auspicious qi or evil qi, is a kind of energy field that appears in the form of waves. Energy waves are penetrating. Just like the waves emitted by our mobile phones. We can still receive calls even if we close the door in the house because the waves are penetrating.
