After the study of the preclusion of exotic meson states in large- limit QCD, combining Weinberg’s opposite proposal, we get different counting orders for a tetraquark operator to create or destroy a one-tetraquark state. Meanwhile, by comparing the tetraquark operator with the mesonic and gluonic operators, we find that tetraquark operators are similar to mesonic and gluonic operators in the counting. Furthermore, we find a mixing of different kinds of operators.
