In this article, we study the and tetraquark states with the QCD sum rules, and we obtain the predictions , , and , which can be confronted to the experimental data in the future. Furthermore, we illustrate that the diquark–antidiquark type tetraquark state can be taken as a special superposition of a series of meson–meson pairs and that it embodies the net effects.
