Are flash mobs illegal gatherings?

There are many flash mob activities in China, and because they are characterized by "fast", the duration of the activities is very short, so they will not pose a threat to social security, as long as the specific actions they perform themselves It is not illegal, for example, if we do a certain action together, and that action is not illegal, then the entire flash mob activity cannot constitute an illegal act.

Moreover, when the flash mob was first born, it may have been a boring act of some young people, but now it has slowly evolved into a group-based, non-limited performance art. It can even be used as a dramatic act. As the content of their activities becomes richer, flash mobs will also become more culturally meaningful and connotative.
