The quarkonia-glueball structure of eta, eta' and eta(1440) 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 J/psi into a vector and a pseudoscalar meson, and radiative decays of J/psi. Corrections due to SU(3) flavor symmetry breaking, non-ideal omega-phi mixing, double OZI and electromagnetic amplitudes of J/psi decays into a vector and a pseudoscalar meson, and three-gluon-annihilation amplitudes of radiative decays of J/psi are included in our analysis. Some predictions on the decays involving eta(1410) are presented, which can be tested at Beijing Electron Positron Collider/Beijing Spectrometer (BEPC/BES) with 50 million J/psi events.
