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.
