Query: Test of the $h_1(1830)$ made of $K^{*}\bar{K}^*$ with the
  $\eta_c\rightarrow \phi K^{*}\bar{K}^{*}$ decay   We present a new reaction, complementary to the $J/\psi\rightarrow \eta
K^{*0}\bar{K}^{*0}$ from which an $h_1$ resonance with mass around $1830$ MeV
was reported from a BESIII experiment. The new reaction is $\eta_c\rightarrow
\phi K^*\bar{K}^*$, or $\eta_c(2S)\rightarrow \phi K^*\bar{K}^*$. Using the
information from the analysis of $J/\psi\rightarrow \eta K^{*0}\bar{K}^{*0}$,
we find that the $K^*\bar{K}^*$ invariant mass distribution for those two
$\eta_c$ decays exhibits a clear peak around $1830$ MeV perfectly
distinguishable from what one obtains with pure phase space. We suggest the
implementation of these reactions to assert the existence of this elusive
resonance which, by its nature as a vector-vector molecule with $0^-(1^{+-})$
quantum numbers, only couples to the $K^*\bar{K}^*$ channel.
