Are there any relevant laws and regulations that can prevent residents from scavenging?

First, according to my country's "Fire Protection Law": "No unit or individual may occupy, block, or close evacuation passages, safety exits, or fire truck passages." Corridors are important fire passages and safety passages in the event of a fire. Exits must be kept safe and clear at all times.

2. Article 3 of the "Interpretation of the Supreme People's Court on Several Issues Concerning the Specific Application of Law in the Trial of Cases concerning Disputes over Differential Ownership of Buildings" stipulates that although the stairway is at the door, the ownership belongs to all owners. Privately using the stair passage to pile up debris is obviously turning public property into private property, and it is also an infringement of other people's rights. Regarding infringement, Article 15 of the Tort Liability Law clearly stipulates that the infringer has the obligation to stop the infringement, remove obstacles, and eliminate danger.

3. Article 83 of the "General Principles of the Civil Law" stipulates: "All parties adjacent to real estate shall correctly handle water interception and drainage in a spirit that is beneficial to production, convenient for life, solidarity and mutual assistance, and fair and reasonable. If it causes obstruction or damage to adjacent parties in terms of traffic, ventilation, lighting, etc., the infringement shall be stopped, the obstruction shall be eliminated, and the damage shall be compensated. "If you still go your own way, you can request the court to order it to be cleaned up.

However, it is time-consuming to appeal to the court. It is recommended that you report it to the local city management department, which is within their scope. Letting the public deal with the elderly may be more effective than simple persuasion.
