From the perspective of geomantic omen, the door is an important air inlet of the house and the primary barrier to dominate the fortune of the house and avoid misfortune. It needs a clean atmosphere, and it is not appropriate to let the surrounding environment affect the cohesion of the room, otherwise it will bring bad results. Changing the door on the wall, if the direction is correct, will promote the promotion of fortune. On the contrary, everything will go wrong, leading to financial ruin. Avoid door taboos.
From the point of view of house demolition and reconstruction, the walls of houses are mostly load-bearing walls, which can not be removed without permission, and it is easy to affect the earthquake resistance, load bearing and structural stability of houses. If the load-bearing walls are changed into doors, they may not be able to withstand gravity and turn the house into a dangerous building. Therefore, it is suggested that the non-bearing wall should be removed as much as possible when the house is demolished and rebuilt.
Why can't the gate be modified at will? In fact, the main reason is that there is a door and a window between the room and the balcony. These doors and windows can be removed and replaced, but the wall under the window can't be moved. This section of the wall is called the "counterweight wall", which plays the role of provoking the balcony like a heavy object. Demolition and alteration of this wall will reduce the bearing capacity of the balcony, lead to the balcony falling, and cause unpredictable consequences.
The door frame of the "three-proof" or "five-proof" door is embedded in concrete. If they are removed, it will destroy the building structure and reduce the safety factor. But also destroyed the building structure at the entrance and increased the difficulty of reinstalling new doors.
So the first thing to pay attention to is to avoid the load-bearing wall. When changing doors, special attention should be paid to avoiding load-bearing walls with beams. For example, this wall is not allowed to be modified at will. I think everyone has heard of the structure of the load-bearing wall. If you change the door here, it will destroy the steel structure of the load-bearing wall, and the house is easily affected by gravity, so the house is likely to become a dangerous building, which is very dangerous for people inside the house.
