There must be a difference between a wall and a wall. One is the whole wall, and the other is the single wall. What we usually call a wall is a whole three-dimensional wall, and then the wall in front of us is a wall with one side viewed from a single position.
For example, most of the walls we see in buildings are called a wall, because you should not only pay attention to the wall, but also pay attention to the wall on one side and the wall on the other. But in the process of decoration, it is necessary to talk about single-sided walls, such as this wall and that wall.

The meaning of wall and wall is actually the same, but the units are different. Both statements are true, but everyone's habits are different. The rooms need to be walled off. One wall is very important. This is called a load-bearing wall. Never rebuild this wall when decorating, otherwise it will probably collapse in the future, which will cause great security risks.
Now many houses need wall decoration when they are being renovated, and the effect of wall decoration is also very good. And when choosing decoration materials, you can choose integrated walls as decoration materials. This material is a new type of decoration material, which is very environmentally friendly and has a good decoration effect.
