The quarkonia-glueball structure of , and is phenomenologically deduced from the updated world average data including two-photon decays of pseudoscalar mesons, radiative decays between pseudoscalar and vector mesons, decays of into a vector and a pseudoscalar meson, and radiative decays of . Corrections due to SU(3) flavor symmetry breaking, non-ideal - mixing, double OZI and electromagnetic amplitudes of decays into a vector and a pseudoscalar meson, and three-gluon-annihilation amplitudes of radiative decays of are included in our analysis. Some predictions on the decays involving are presented, which can be tested at Beijing Electron Positron Collider/Beijing Spectrometer (BEPC/BES) with 50 million events.
