We investigate the possibility of producing the enhancement observed in $J/\psi\to \gamma X$ with $X\to \omega\phi $ at BES by intermediate meson rescatterings through $f_0(1710)\to PP\to \omega\phi$, $f_0(1710)\to VV\to \omega\phi$, and $f_0(1710)\to SS\to \omega\phi$. We find that intermediate meson rescatterings can produce some enhancement near the $\omega\phi$ threshold. Implications about the property of this enhancement are discussed.
