The unique artistry of a tulou building lies not only in its unique appearance, but more importantly, lies in the fact that it creates a small world meeting customary and humanistic needs. Both Hakka and Minnan tulou buildings are inhabited by patriarchal communities. Except for ancestral halls that are hierarchical, all residential spaces surround on an equal basis, and are not hierarchical. However, as seen from the organisation of internal architectural spaces and courtyard spaces, the Hakka people stresses publicity, whist the Minnan people stresses privacy, reflecting their different cultural backgrounds.
