Where is the correct position of the exhaust fan in the painting room?

In the decoration of China, we can look at the nature of the exhaust fan, and then we can find out the technical quantity where it should be placed. The function of the exhaust fan is to draw dirty air out of the room through the rotation of the blades. In this way, we get two attributes. The first is "movement", which is naturally due to the rotation of blades; The second is "Qi", because it has a way to draw the indoor breath out of the room. In metaphysics, "dynamic" and "qi" are two extremely important theories, which, if properly grasped, can even reverse people's luck.

In China decorative geomantic omen, "moving" belongs to Yang, which means "developing", "striving" and "strengthening", so many geomantic omen will use "moving" things to enhance their strength in a certain direction, such as fish tanks (fish and water are moving things) and clocks with pendulum clocks. It can be inferred that the movement of the exhaust fan is in line with the principle of the movement of geomantic omen, so the position of the exhaust fan must be placed on the auspicious side of the house, such as anger, life extension and heavenly doctor in the Eight Houses Theory, or the prosperous side of seven reds and eight whites in the flying stars of Jiugong, so that the strength of the auspicious side can be drawn up. On the other hand, if the exhaust fan is placed in the "desperate", "five ghosts" and "six evil spirits", or unfortunately placed in the evil spirits of "Huang Wu" and "Erhei"; It is Sha Qi that has been strengthened.

This theory is generally based on "aerodynamics". Since the suction fan has a "pneumatic" function, it should be placed where it can increase good luck. There are so-called "left green dragon", "right white tiger", "pre-suzaku" and "post-Xuanwu" in Feng Shui, which is the theory of Luan Tou and can also be regarded as a kind of environmental science. If we face the wall facing the door, then the wall on the left side of the door is the "Qinglong" surface, and the wall on the right side of the door is the "White Tiger" surface, which is the main evil. Therefore, if the exhaust fan is installed on the "Qinglong" side, it can increase the good luck of the "Qinglong" side.
