Is it a responsibility for a man to hang his belongings in an unlocked underground garage door in the community?

Residential property has no responsibility. According to the provisions of Article 20 of the Tort Liability Law of People's Republic of China (PRC), the tort liability does not include the damage caused by force majeure or other events not attributable to the infringer. The man hanging himself in the corridor of the residential area is an event that cannot be attributed to the residential property, so the property is not responsible.
