These states are compact exotic hadrons which can be approximated as the diquark-anti-diquark correlations. In the flavor SU(3) symmetry, they form an SU(3) triplet or anti-sextet. The spectra of the stable doubly heavy tetraquark states are predicted by Sakharov-Zeldovich formula. We find that the $T^+_{cc\\bar{u}\\bar{d}}({\\bf 3})$ is about 16MeV below the $DD^*$ threshold, while $T^{-}_{bb\\bar{u}\\bar{d}}({\\bf 3})$ is about 73MeV below the $BB^*$ threshold.
