Who is responsible for the accident that the manhole cover of the residential heating company was privately mentioned by the residents?

The manhole covers distributed in the residential area shall be maintained by the residential property maintenance unit. Covers distributed on urban roads shall be maintained by the municipal facilities management department. If it's the quality of the manhole cover, it's the property, and they should be responsible for the maintenance. What responsibility is also a property commitment. But it is the tenant's responsibility to open it privately, and the tenant is fully responsible, which has nothing to do with the property.

Article 937 of the Civil Law of People's Republic of China (PRC) stipulates that "a property service contract is a contract in which the property service provider provides the owner with property services such as the maintenance of buildings and their ancillary facilities, the management and maintenance of environmental sanitation and related order, and the owner pays the property fee".
