A circle was drawn on the undecorated wall, and some words were written in it. What do those words mean?

These marks are usually marks left by decoration workers in the construction process, which are used to express specific details or explanations. But different workers may have different marking systems, so the specific meaning may need to be determined by consulting relevant personnel. Generally speaking, these marks do not mean that there is a problem with the house itself, but only for the needs of decoration and construction. If you are not sure or worried about these traces, I suggest you contact the developer or decoration worker to get an accurate explanation and explanation.
