What should I do if the wire in the community is broken? Who is in charge?

Legal analysis: if the cable in the residential area is damaged, the property should be responsible for the maintenance.

Legal basis: Article 52 of the Property Management Law of People's Republic of China (PRC), water supply, power supply, gas supply, heating, communication, cable television and other units shall be responsible for the maintenance and conservation of relevant pipelines, facilities and equipment within the property management area according to law. If the units specified in the preceding paragraph temporarily occupy or dig roads and sites due to maintenance, they shall promptly restore the original state.
