What does the service charge include? Should the owner leave things in the community to manage the property?

"Property Management Regulations" Article 41 The owner shall pay the property service fee in accordance with the provisions of the property service contract. If the owner and the user of the property agree that the user of the property shall pay the property service fee, the owner shall bear joint and several liability from the agreement. Article 64 of the Property Management Regulations violates the property service contract, and the owners fail to pay the property service fee within the time limit, and the owners' committee shall urge them to pay it within a time limit; If it fails to pay within the time limit, the realty service enterprise may bring a lawsuit to the people's court.
