Disputes (missed decoration) cannot mediate the other party's extortion. How to deal with honest people?

Personally, I suggest that the victim consult a lawyer, hire a lawyer to sue if possible, and find relevant departments to complain to the local police station. At the same time, collect and sort out the evidence of all parties (neighbor's aggression and police station's inaction), and publicly expose it on public platforms such as Weibo as a last resort.
