The core of traditional geomantic conception is axisymmetrical theory. That is, a straight line is extended from a certain point, that is, sitting on a mountain, along this straight line, spreading left and right, spreading back and forth, forming a symmetrical figure (symmetrical figure means: a figure is folded in half, and the shapes on both sides can completely overlap along this line), which is considered to be the most standardized Feng Shui scheme. In the natural state of the site, the terrain is complex, but the basic idea is to find the balance point of relative and symmetry and evaluate the concept of symmetry of the central axis. Such as: Zuo Qinglong, right white tiger; Vestibular case, leaning against the mountain; Tianxin uses ten things. All activities are based on the thinking concept of axis symmetry.
In history, door opposition is inevitable, and door opposition is a new argument and theory invented by modern people.
There are old houses in my hometown, all facing each other, several doors facing each other, and the doors are in symmetrical positions. When I was building the house, I suggested changing the position of the door from a convenient point of view. The old carpenter firmly opposed it, saying: he has a teacher's biography, arbitrarily changing places, and is not responsible for anything. The main idea of the old carpenter's teacher is door to door. I have repeatedly compared and thought about this in the use of the house in the future. If the door is wrong, the double-door room must be opened obliquely, thus forming an oblique streamline in the room, making it difficult to place furniture and articles, and obviously narrowing the effective use area of the room. If the doors are opposite, the flow line formed in the room is straight on one side, which is convenient for furniture placement and the effective and practical area of the room is obviously widened. It turns out that what the old carpenter said is the so-called teacher's theory, but it actually involves a big scientific question asked by a university-the effective practical area of the house.
Before the Qing Dynasty, there were seven doors in the residence of the Chief Secretary's Office of Guangdong and Guangxi, from the main gate to the inner hall, which were in a straight line, the same size and style, but the straight line was opposite. Another feature of the house here is the symmetrical pattern, that is, there are doors on the left, doors on the right, windows on the left, corridors on the left and corridors on the right. The left and right rooms are big and small, long and short, high and short, and they can completely overlap and be symmetrical. Even the feldspar strips on both sides of the corridor are laid symmetrically. Behind the house is the house for government agencies, which was reserved until the new house was rebuilt and sold in 1986. This family once supported 16, a famous feng shui teacher in China, and presided over the building. Do those people really don't understand Feng Shui? The seven doors are in a straight line, the central axes are opposite, and the left and right houses, doors, windows, corridors and feldspar cornerstones are laid relatively. Modern people are so smart, as long as they see another door from one door, it's like discovering the new American continent, and everyone is shouting, aren't you right? When two doors are facing each other, one will retreat. This statement is the final conclusion, and it has been clearly pointed out that it is relative between neighbors, not the same house. This kind of relative must be relative to the lobby door on the central axis, including the ancestral hall in the lobby, rather than a relative who is right at the sight of the window.
