Who confiscated Jia Kai's bare sign?

Confiscating Kay's light sign is a security guard. When TFBOYS imagined the fifth anniversary of the concert, officials emphasized the safety of many concerts, saying that lights with specifications of 50 times 50 or more could not be brought into the venue. Fans thought they could bring them in by hiding the lamp, but the security guard found them. Seeing that the security guard had collected a big bag of light cards and dragged them away, fans thought that they could hang up if they brought them in. As soon as I entered the arena, I grabbed the railing and posted my own placeholder stickers. Unfortunately, they were only happy for three seconds, and fans in Karry said that their ribbons were torn off by security guards. After the ribbons left by Karry fans were taken down, the ribbons of Roy and Jackson's fans were also taken down to avoid the security risks caused by hanging large light signs. It's so hot now that it's easy to catch fire.
