When the community handed over the house, there was a fountain in the community and the property management later demolished it. Is it illegal for the property management to do this? If it is illegal

The property manager is just a property manager jointly hired by all the owners of the community. It is a master-slave relationship. All facilities in the community belong to the joint property of all owners. And the cowherd boy sold the cow. Isn’t this a big joke? You can file a lawsuit and ask for the infringement to be stopped and the (public facilities) to be restored to their original condition.
