  In this article, we study the ground states and the first radial excited
states of the tensor-tensor type scalar hidden-charm tetraquark states with the
QCD sum rules. We separate the ground state contributions from the first radial
excited state contributions unambiguously, and obtain the QCD sum rules for the
ground states and the first radial excited states, respectively. Then we search
for the Borel parameters and continuum threshold parameters according to four
criteria and obtain the masses of the tensor-tensor type scalar hidden-charm
tetraquark states, which can be confronted to the experimental data in the
future.
