What is the name of the management building?

Landlord system. In order to facilitate management, the responsibility lies with people. Now, a management system of "the first person in charge" is popular, and the people who manage a building are collectively called building directors. The implementation of this system has greatly improved the management level of the whole building, because the responsibility is implemented to people, and the person in charge does not dare to relax at all, and it also avoids the phenomenon of passing the buck after the accident.
