Does the property inform the merchant or ask the owner?

It's better to ask the owner for instructions about the property. When a new property enters a residential area, it must notify the owner to handle the handover procedures, so that the owner can cooperate when collecting property fees. If you don't inform the owner, there may be a lot of accounts with the old property company that are not entangled clearly, and there will be a lot of inconvenience in the future.
