It is the double-sided tape that is temporarily fixed. Thank you for the inconvenience to adopt.
Try it with an eraser or put a hot towel on it and wipe it off.

Glue marble with marble glue. Stainless steel sinks and marble with Dow Corning medium-sized glass glue.
Rub it with wind oil essence or nail polish water and wait for about a minute to soften, then use dry fine powder (lime powder, flour) to stick it with a cloth and rub it hard, don't rub the door away.
Then use double-sided tape (temporary fixation) and add structural adhesive as a long-term fixation, so that it will not fall off again.
