  Beijing Spectrometer (BES) at Beijing Electron Positron Collider (BEPC), IHEP
has accumulated 2.5 $\times 10^7$ J/$\Psi$ and plans to increase the number to
$10^8 \sim 10^9$ in the near future. In this paper I review and summarize the
recent studies on the possibilities of probing for new physics at BES. This
includes the theoretical works on and experimental attempt performed at BES in
searching for flavor changing neutral current, CP violation and lepton flavor
violation in the processes of J/$\Psi$ decays.
