Who will eradicate the gangsters in the community and give the community a peaceful environment?

You can only deal with a man as he deals with you.

How to explain it specifically? If the hooligans in your community are really hateful, they will definitely cause everyone's dissatisfaction. You can contact everyone to manage the gang in a gangster way. They are bullies. When they find that you are not easy to bully, they dare not bully you.

Contact the people in this community through the internet to manage together, or live in fear every day, can you live comfortably? It's best to solve the problem in a day or two. Really, in fact, they are most afraid of things that are stronger than them. If they oppress you, your life will be very difficult.

In addition, you can call the police, but generally there are no special circumstances and the police will not mind their own business.
