How to politely disperse the square dance moms?

Auntie Zhang had a vague feeling that the square was not clean today.

The most obvious feeling is that when she dances there is always a light from somewhere that shakes her eyes. It was clearly nighttime, and there had never been a moving light source before. She struggled to overcome the vertigo and looked in the direction of the light source, only to see nothing but a blackness like ink.

You're wearing a black hoodie, and you've hidden a small piece of mirror in your pocket, taking it out every few steps and spinning it around aiming it at the square of square dancers of the older women, knowing that it will always flash a few of them. Before they could react, they put away the mirror and quickly moved to the other direction, as they did. The light from the streetlamp refracted by the mirror is just enough to create a flickering effect, and this is the best scenario you've come up with after experimentation.

The next day, you carry a small Bluetooth speaker in your pocket, walk slowly, and play the sound of a baby's cry that you recorded long ago, at a volume level just a little lighter than square dance music. The moms slowed down and exchanged glances: did you hear that?

The morning of the third day, Auntie Li bought a fish at the market and went home, cut open the belly of the fish, which was actually a piece of cloth, inscribed: Who ↘ disturbed cur tt? 朙?

In the course of the amazons' gossip, the versions of the story spread more and more bizarre, and in the end they automatically fill in the whole story for you.

On the fourth day, a link duly appeared in the amazons' WeChat circle of friends: shock! The latest U.S. study found that square dancing is bad for your health. It describes in detail the facts that "every minute of square dancing will reduce your life expectancy by sixty seconds", "experiments have shown that a liter of air extracted from a square dance venue was injected into the bodies of mice, which died", and "a large number of statistics show that 99% of square dancers will die after fifty years of square dancing", which is justified and convincing.

After dark on the fifth day, no one went square dancing anymore.?
