Why were feminists arrested?

They were detained in the name of disturbing public order, but they were all released on bail.

I was locked up for a month, and later I was released on bail pending trial.

The five women's rights sisters originally planned to welcome Women's Day with the activity of "advocating the prevention mechanism of bus sexual harassment" on March 7, with the theme slogan "Stop sexual harassment, be safe for you, me and her" to remind people of the sexual harassment of women by illegal men on crowded subways and buses. However, they were arrested by the police before the activity started.
