Recent results on charmonia decays at BESII/BEPC are reported, including the
observation of psi'-->K_S K_L, psi'--> Vector + Tensor and psi'--> Vector +
Pseudoscalar 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 test of the color-octet mechanism via chi_cJ --> p
\bar{p} and chi_cJ-->\Lambda \bar{\Lambda}; the first observation of chi_c0-->
f_0(980)f_0(980); and a study of the psi' and chi_cJ decays with K_S K_S in the
final states.Comment: Invited talk in MESON 200
