Newly observed two charmed-strange resonances, and
, are investigated by calculating their Okubo–Zweig–Iizuka-allowed strong decays, which shows that they are suitable candidates for the
and
states in the charmed-strange meson family. Our study also predicts other main decay modes of
and
, which can be accessible at the future experiment. In addition, the decay behaviors of the spin partners of
and
, i.e.,
and
, are predicted in this work, which are still missing at present. The experimental search for the missing
and
charmed-strange mesons is an intriguing and challenging task for further experiments.
