Next time this happens, secretly record the video and call the police first. Put the video on the internet and the media, and then ask your friends to help you hype it online. Once it gets hot, I'll tell you that they can't, and even if it has something to do with the mayor, he won't dare to help. I believe in the power of netizens!

If you are not sure, you can either retire by yourself or larger foe. Society is like this!
