Feng Shui pays attention to "hiding wind and gathering qi", which can be described as the "secret" in the Tao. Modern science shows that there is an invisible gas field on the human body, which is formed by the continuous flow of energy generated by the human body. The "Qi" interwoven by this energy flow, which is necessary for maintaining life (this "Qi" has been photographed by special photography technology), is called "Qi pulse". This kind of gas field is inseparable, which is equivalent to wearing a layer of "armor" and adding a protective layer to the human body. If this gas field is lost to a certain extent, the human body will be attacked by external bad factors and get sick. This kind of "qi" is the weakest when people rest and fall asleep, and it is also the time when they are most affected by external bad factors. Someone has done experiments. When sleeping in an open place, the "qi" around the human body is weaker than when sleeping indoors. The ancients made a judgment in the living environment: "There are many villains in the house, and the spirit is flourishing", which coincides with the theory that the human gas field gathers and disperses in the external environment.
There are indeed such examples in practice. The "Yangxin Zhai" in the Forbidden City in Beijing, that is, Yong Zhengdi's study on the west side and his bedroom behind it, covers an area of just over 10 square meter. If you pay attention to the visit, you will find that there is nothing special about the area of the emperor's bedroom and the size of the wooden bed, but the wooden bed is close to the wall and adopts the principle of "the bed should have a mountain (backing)". It can be seen that the emperor did not afford to live in a big bedroom, but chose a "nourishing" bedroom for health.
