We systematically construct all the tetraquark currents/operators of JPC = 1+- with the quark configurations , , and ( ), and derive their relations through the Fierz rearrangement of the Dirac and color indices. Using the transformations of and , we study decay properties of the as a compact tetraquark state; while using the transformation of , we study its decay properties as a hadronic molecular state.
