Feng shui as a nail wall

In fact, there is no mystery, so nail the knowledge to prevent the wall from expanding and causing the wall to collapse. In fact, there are many ancient dwellings with nails in Shanxi, and these nails are generally diamond-shaped. As long as they are built in older dwellings, they can be seen everywhere. In fact, this has a great source. In ancient times, people who could build houses with bricks in ancient times were very rich. Generally, it is impossible for different families to build houses with blue bricks, because they are all poor and can't afford to raise their youth, which was very expensive in ancient times. But even in very wealthy families, when people build houses, they are not all made of blue bricks. But between the blue bricks, some bricks or mud will be filled. ?

I don't know if you have noticed that the walls of houses behind such ancient dwellings are generally very thick, about 50 cm. If all houses are built with blue bricks, there is no need to nail both sides of the wall. It is precisely because they filled some soft soil and other sundries between two bricks that ancient people nailed the wall with long nails to make it stable at once in order to ensure that the wall would not collapse and expand.

In ancient times, when people built houses, they all had shadow walls, most of which were very delicate and beautiful. The carving technique of the screen wall is very exquisite. Compared with the concealment in other places, the concealment in the gate of the ancient house is very particular and people attach great importance to it. But building your own house is expensive, so most people don't use blue bricks to build their own houses. But when making a screen wall, I dare not be vague at all. ?

Such as the Wang Family Courtyard in Shanxi and the Qiao Family Courtyard in Qixian County. When you look at these famous buildings, there will be these diamond-shaped nails on their walls. I have to admit that the wisdom of the ancients was really strong.
