Is the property responsible for thieves entering the house?

Not necessarily, because the property service is a public service, a service contract, not a custody contract, and the owner's home is stolen. As long as the property company provides services in accordance with the service contract, it is not a breach of contract and does not need to bear responsibility. However, if the owner can prove that the property management company did not provide services in accordance with the contract and there is a causal relationship with the theft, he can bring a lawsuit to the court and the property management company will bear part of the responsibility.
