Description
As an iso-spin partner of the charged $Z_{cs}(3985)$ state, the evidence for a neutral near-threshold structure in the $K_s$ recoil-mass spectra in $e^+ e^- \to K_s (D_s^- D^{*+} + D_s^{*-} D^+)$ will be reported. Also, there will be report of searching for $X(3872) \to \pi^0 \chi_{c0}$ and $X(3872) \to \pi \pi \chi_{c0}$ at BESIII. For the $Y$ state, the cross-section measurements of the $e^+ e^- \to D^{*+} D^{*-}$ and $e^+ e^- \to D^{*+} D^-$ processes at center-of-mass energies from 4.085 to $4.600~\rm GeV$ will be given in this talk.
