  $\chi_{c0}$, $\chi_{c1}$, and $\chi_{c2}$ decays to $\pi^+\pi^-K^0_SK^0_S$
and $K^+K^-K^0_SK^0_S$, as well as $\psi(2S)$ decay to $\pi^+\pi^-K^0_SK^0_S$
are presented. The branching fractions of these decay channels are determined
using $14\times 10^6$ $\psi(2S)$ events collected at BESII/BEPC. The branching
fractions of $\chi_{c0},\chi_{c2}\to K^0_SK^0_S$ are measured with improved
statistical precision.
