The serious accident of a screen falling during the MIRROR concert drew much attention from the general public. On the evening of August 1, the government released a photo inside the coliseum saying that from initial evidence, one of the steel cables connecting the screen was found to have snapped open.
Combining the photo and other information, people start to speculate that one of the steel cables linking the screen might have first become loose, leading to the other cables not being able to take the extra load, which eventually broke and caused the screen to fall. But at the moment it is still not able to confirm why the cable became loosened in the first place.
