Alarm and filing: You have taken correct actions, and alarm and filing are the first steps to safeguard your rights and interests. Please keep in touch with the local public security organs and provide any possible evidence or witness testimony.
Active communication: try to actively communicate with neighbors upstairs and try to solve disputes. You can seek the help of the community, neighborhood committees or other mediation agencies to help resolve disputes.
Legal consultation: consult a lawyer to know your rights and interests and legal channels. Lawyers can help you assess whether there is enough evidence to file a lawsuit and what legal action to take to protect yourself.
Complain to the government: If you think you have been treated unfairly, you can complain to the local government department. You can usually contact the local neighborhood committee, community office or civil affairs bureau to reflect your problems and ask for intervention.
Seek the support of the media or social organizations: Sometimes, exposing problems to the public or helping through social organizations may attract more attention and force relevant parties to take action.
Please note that it may take time to resolve disputes, and the result may not be what you expect. Therefore, cooperation with professionals (such as lawyers) and active communication with local governments and community organizations are the key to solving problems. At the same time, continue to safeguard their legitimate rights and interests and ensure the safety of themselves and their families.
