We investigate the mass spectrum and the decay properties of the mesons within the screened nonrelativistic quark model and the model. Our results suggest that the and states, as the first solution of the recently LHCb measurements, could be explained as the and , respectively. In addition, the and states, as the second solution of the LHCb measurements, could be explained as the and , respectively. Meanwhile, the could be interpreted as the candidate of the . We also calculated the decay properties of the other excited mesons with the predicted masses, which should be helpful for the experimental searching in future.
