  Recent results on charmonia decays at BES/BEPC are reported, including the
observation of psi'-->K_S K_L, psi'--> Vector + Tensor for the measurement of
the relative phase between the strong and electromagnetic decays of psi' and a
test of the pQCD ``12% rule'' between psi' and J/psi decays; the study of
psi'--> gamma gamma J/psi for the determination of psi'--> pi^0 J/psi, eta
J/psi, gamma chi_c1 and gamma chi_c2 decay branching fractions; the test of the
color-octet mechanism via chi_cJ--> p \bar{p} and chi_cJ--> \Lambda
\bar{\Lambda}; and a search for the CP violating process psi' and J/psi--> K_S
K_S.
