How to compensate for the occupation of blank houses by property decoration?

In this incident, the property failed to fulfill its security obligations to the owner's house, and others were allowed to decorate it at will, and the property was not warned or stopped. Its behavior has damaged the owner's house and violated the owner's house ownership, which is illegal. Property damage caused to the owner's house needs to bear civil liability for compensation, including restitution, cessation of infringement and compensation for losses. If the circumstances are serious, you need to bear criminal responsibility, because it may constitute the crime of trespassing.
