I have a rogue idea. Say it for your reference.
Gather a group of brothers and sisters, put up some banners, block their ivy doors, and ask the first leader to come out and talk to you. Of course, this is not an end, but an impact. Let a friend videotape the whole process. After the crowd gathers, let that friend call the police and report to the media. Keep blocking the door until the police and the media arrive. After the police arrived at the scene, they actively cooperated with the police comrades, cried their tragic experiences to the responsible police officers and sought solutions. By this time, the media should have arrived. Friends who record videos can communicate with the media and provide video materials.
All of the above is to put pressure on Ivy, and as long as she can achieve her goal, she will stop.
