The tiles on the outer wall of the residential area have different degrees of bulging. How to write a warm reminder?

Tips: Due to the long time of exterior wall decoration, the tiles have fallen off recently. Please pay attention to safety when passing by and try to bypass. Thank you for your cooperation in our work, and wish you a happy life! If the external wall tiles fall off, it is suggested that the tiles can be knocked off before paving. When laying tiles, there should be a certain gap between tiles to prevent the tiles from squeezing due to thermal expansion and cold contraction in the future, and then falling again. We can also pay more attention to the maintenance of tiles, which can also increase the service life of tiles.
