How to judge whether "performance art" is illegal?

1 Too many participants will be suspected of illegal assembly;

2 Too many onlookers will be suspected of disturbing social order;

Any slogan, banner and related items are suspected of marching and need to be reported to the public security department for approval;

I suggest that you either make a "flash", short-term, instant, and break up after the game; Or it will be held at a public meeting on Christmas Eve or the countdown to the New Year.

With the present degree of freedom, under normal circumstances, the public security mostly ignores you. But there must be a reason. You have a legitimate reason. Once a decision is made, participants can say that organizers and core members need at least a cup of tea to chat.

Judging from the development of performance art now, its expression mode will be less and less aimed at showing to the public. One is in the form of image data, the other is in the form of long-term and multi-space event process, and the other is more and more brought into the social system, similar to the form of jigsaw puzzles and people imitating MJ;

In other words, you are the third category at best, but the third category can greatly cooperate with the society and you can report it.

If nothing else, the police must ask which pedestrian street has toilet paper mummies.
