Abstract: In light of the recent data from BES collaboration for $\chi {c0}\to VV$,$PP$ and $SS$, and from CLEO-c for $\eta\eta$, $\eta^\prime\eta^\prime$ and$\eta\eta^\prime$, we present a detailed analysis of the decays of heavyquarkonia into light meson pairs such as $\chi {c0,2}\to VV$, $PP$ and $SS$ ina recently proposed parametrization scheme. An overall agreement with the datais achieved in $\chi {c0,2}\to VV$ and $PP$, while in $\chi {c0}\to SS$ we findthat a possible existence of glueball-$q\bar{q}$ mixings is correlated with theOZI-rule violations, which can be further examined at CLEO-c and BESIII in$\chi {c0}\to SS$ measurement.
