There will inevitably be contradictions when people get along with each other. If you meet an unreasonable person, you can just ignore her. Don't meet until you meet.
2. Live in harmony at ordinary times and avoid conflicts with neighbors.
Don't have conflicts with your neighbors, try to restrain yourself, even if there are contradictions, you need to try to avoid bigger contradictions. If you can't afford it, hide it. Don't give each other a chance to find fault.
3. If you don't want to come forward, you can consult with the property and mediate the contradiction.
Neighbors have conflicts, but they don't want to communicate in person. You can find a property and be a bridge in the middle. After paying the property fee, the property should help mediate the contradictions between neighbors.
4. You can call the police and let the police intervene to deal with the problems of the two companies.
The feud between neighbors is deep, which interferes with normal life and the property can't mediate. You can choose to call the police and let the police intervene to deal with the problem.
Neighborhood is not the last step, don't go this far, try to coordinate yourself. This will only deepen the contradiction between the two families.
5. Sue each other in time and protect yourself by legal means.
If there is a civil dispute between them, and the two parties cannot coordinate, the court will mediate to safeguard their own interests, and the court will mediate first. And if the case is won, all litigation costs will be paid by the losing party. It is the wisest and best way to solve the problem through legal means.
