Are the doors and windows on the first floor of the villa not allowed to open to the outside?

It's best not to drive outside, which is prone to danger. First, glass is easy to fall and hurt people, and second, it is easy to damage windows when the wind is strong. Although it is on the first floor, it can't be opened to the public because of hidden dangers that hinder the normal passage of roads.

Generally speaking, northern cities basically choose to open windows from the inside, while southern cities basically choose to open windows from the outside. However, there are clear regulations in some places that high-rise buildings must choose to open windows from the inside or push and pull windows, and windows must be fixed. In case of heavy wind and rain, the windows of high-rise buildings are not closed in time, which is easy to fall off. When installing a window to open outward, it must be to ensure the quality of the window, and the fixing effect must be good.
